Section 1 Executive~ Summary Introduction A performance contract is an agreement between an energy services company (ESCO) and a facility owner, under which the ESCO designs, engineers and implements needed facility improvements and upgrades. The ESCO guarantees the owner that savings from those upgrades will occur over the course of the performance contract. The guaranteed savings from reduced utility bills and material savings are then used to pay back the initial capital investment in equipment and installation. Thus, the owner merely redirects existing budgeted dollars, which are currently being paid to their utility companies, back into their facilities in the form of capital improvements. Afterwards, the facility owner retains 100% of the savings to use at its discretion. In the State of Kansas, the Kansas Energy Office allows public entities to utilize the state's Facility Conservation Improvement Program (FCIP) to implement these projects. By utilizing this program, energy experts from the State have been involved in all project development and oversight and have performed a thorough review of the engineering and energy savings calculations to ensure that the City of Salina is receiving the best possible project. The Kansas Energy Office will maintain it's involvement in this project throughout construction and for the life of the project. From the onset of this Investment Grade Audit, it has been the intention of Chevron Energy Solutions to align this energy conservation and capital improvement project with the stated goals of the City's 2008 Shared Vision Statement and Strategic Plan. In that plan, the City calls for a well maintained city with the highest possible quality municipal services, the start of efforts to be an environmentally friendly "green" community, and making practical efforts to preserve natural resources. This Performance Contract with Chevron Energy Solutions contributes. directly to all ofthese issues. This program directly conserves energy and water resources in City facilities to not only save energy dollars that can be reinvested, but to also having a positive environmental impact on the City's carbon footprint. In fact, the energy savings as a result of the recommended program equate to removing 74 cars from the road or planting 93 acres of trees each year. Knowing that water is increasingly becoming a scarce resource, this program also goes to great lengths to conserve water wherever possible. In addition to the energy and water reductions, this program provides capital improvements at the Police Station and the Health Department, to give City employees and citizens a better working and living environment, and provides an opportunity to make these improvements now instead of little by little over time on an emergency basis. The process of implementing a performance based guaranteed energy program, as practiced by Chevron Energy Solutions through the Facility Conservation Improvement Program includes the following four phases: Chevron ~ Energy Solutions 1-1 . . . Section 1 Executive: Summary Phase I II III IV Description Feasibility Energy Analysis Investment Grade Audit (IGA) Implementation Measurement and Verification This report documents Phase II of our process, the Investment Grade Audit. In developing this report, Chevron ES has worked on-site with the City of Salina personnel to address the concerns of the facilities and uncover areas for energy conservation opportunities. Beginning the first week in June 2008, Chevron ES staff visited the nine (9) City facilities included in the scope of the project to collect information. We examined every component and system that uses energy, including lighting, mechanical systems, building envelope systems, internal electrical systems, and miscellaneous "plug load" equipment. On following visits, a detailed survey of each lighting fixture and water fixture in the nine buildings was performed by specialized teams. Our data was collected by direct observation of equipment, site drawings, operating schedules and other relevant data. We also conducted interviews with City personnel to gain a better understanding of operational issues and their objectives for this program. After several months of analysis and subsequent site visits, Chevron Energy Solutions has been able to design a program that will maximize savings in order to address deferred maintenance issues while improving comfort and operational controL In addition to the physical surveys, Chevron Energy Solutions and the Kansas Energy Office held several meetings with City Administration to determine which capital improvement issues were most pressing and could be addressed through this program. Through these discussions, the much needed improvements at the Health Building and the Police Station were brought to light. Both of these buildings require significant facility improvements that the City has not been able to budget necessary funds for a comprehensive solution. This Performance Contracting program will allow the City to make the necessary changes and improvements to these buildings now to improve comfort, control and operational maintenance, instead of waiting for available funds from the City's capital budget. Through this team effort, Chevron Energy Solutions was able to identify savings opportunities that will improve the City's facilities and provide a reduction in maintenance costs. Through implementing an energy savings performance contract, the City of Salina will be able to pro actively solve facility needs through a proven mechanism ensuring a guaranteed fixed price and no additional taxpayer burden. This program solves problems now through money that was previously going to your utility companies and has a tremendous positive impact on the environment. Our program focused around the six general categories: . Lighting Conservation Measures . Mechanical Improvement Measures . Building Envelope Improvement Measures Chevron ~ Energy Solutions 1-2 . . . Section 1 Executive Summary . Equipment Control Conservation Measures . Water Conservation Measures . Utility Sourcing Alternatives Chevron Energy Solutions is pleased to present a customized energy savings improvement program for the City of Salina. Our meetings with Mr. Jason Gage, Mr. Steve Snyder, Mr. Byron Erickson and the rest of the City personnel outlined their goal to maximize potential energy savings and leverage excess savings. We would like to express our thanks to all of the staff members that provided assistance during our visits and telephone calls: Jason Gage, City Manager Steve Snyder, Director - Parks and Recreation Byron Erickson, Facilities Superintendent Jim Meyer, Bicentennial Center John Highkin, Smoky Hill Museum Michael Spicer, Salina Community Theatre Jack Rolfs, Director, IT Department Margaret Kay, Accounting Cindy Beneke, City of Salina Water Department Loralee Tibbetts, Health Department Additionally, we would like to recognize the Chevron Energy Solutions Team: John O'Herron, Business Development Manager Ron LaCombe, Senior Project Manager Randy Jameson, Project Manager Jacquelynn Morris, Lead Project Engineer Brandon Well, Energy Analyst Jason Patterson, Engineering Intern Steve Schulte, M&V Specialist Our objective is to provide a comprehensive list of energy conservation measures (ECMs) and energy related capital improvement measures (CIPs) to assist the City of Salina in tailoring a program that addresses immediate facility and operational needs as well as long-term infrastructure needs.

Section 4 Operations and Maintenance includes details ofthe operations and maintenance savings and capital avoidance savings associated with implementation of the ECMs and CIPs, as well as some general O&M guidelines. Section 5 Data on Present Facilities summarizes the current types of mechanical, lighting, heating, ventilation and air-conditioning (HV AC), and control systems in the buildings. Section 6 Measurement and Verification, describes the recommended methods of savings verification employed by Chevron ES to assure that actual savings meet or exceed projected savings. Section 7 Environmental Impact, discusses the environmental benefits of the project, including reduction in emissions and removal/disposal of PCB ballasts. Appendices include various supporting documentation as listed in the Table of Contents. Recommendations The recommended program includes comprehensive water and lighting conservation programs at all nine buildings, and controls projects, a building improvement project, and alternative sourcing of natural gas at selected buildings. At Fire Stations No. 1 and No.2, the golf clubhouse, the Health Department building, and the Salina Community Theatre the program includes installation of network programmable thermostats. Controls at the Smoky Hill Museum will receive some modification to reduce energy consumption at this building. The mechanical projects include replacement of five aging HV AC units at the Health Department. To address some significant comfort needs at the Police Department building, the feature project in the program is the replacement of the HV AC air handling units and control system. The program also includes replacement of a leaking skylight in the Health Department building and replacement with an insulated roof and ceiling. Utility cost savings will be realized with consolidation of gas meters at the golf clubhouse and bulk purchasing natural gas for the Bicentennial building, the Memorial Hall, and the Police building. Table 1-1 provides a summary of the projects in the recommended program. Detailed descriptions of each proposed measure, as well as the other measures that were evaluated, are provided in Section 2 - Energy Conservation Measures. This section also includes several projects initially considered but not recommended due to length of payback or other reasons. Chevron ES will work with the City to tailor a program that best meets the City objectives. Chevron _ Energy Solutions ... 1-4 . . .

Construction Costs are vaiid for 90 days from October 1, 2008. Ener2V Savin2s Performance Contract Benefits to the City of Salina: The City of Salina will derive many benefits from the implementation of a comprehensive energy performance contract. Just a few of the benefits are listed below. . Improved Working Environment: New and improved HV AC systems and temperature controls will provide a more comfortable working environment for the City of Salina staff and visitors. Additionally, lighting will be upgraded throughout all facilities. New lighting systems are designed to meet the llluminating Engineers Society (IES) standards. . Cost Control: Performance contracting provides a means to divert monies to facility improvements that would otherwise be spent on paying utility bills. Many of the items planned for replacement are well beyond their useful, functional life. Therefore, these are items that the City will need to replace in the near future. Through this performance contract, the City of Salina is able to pro actively make these improvements at one time, utilizing energy saVIngs and very favorable Interest rates to help fund the replacements and also lesson the burden on taxpayers. This program has a guaranteed fixed cost which also eliminates change orders from the construction. Chevron V Energy Solutions 1-7 . . . Section 1 Executive Summary . Energy Savings and Environmental Impact: The proposed energy conservation measures will reduce energy consumption and costs. The reduced energy consumption will result in less power plant consumption from the electric utility and much less natural gas usage as well. Other examples of positive environmental actions with some of the ECMs include removal of hazardous light ballasts. Implementation of the project will make a strong statement about the City's commitment to energy efficiency and environmental responsibility. . Reduced Maintenance: Several ofthe ECMs will significantly reduce maintenance costs and hours. No financial savings have been claimed for the City of Salina Facilities Department in-house labor savings. However, several of the projects will result in significant labor savings, freeing up the maintenance staff to address other items. Conclusion Chevron Energy Solutions recommends that the City of Salina move forward with a guaranteed energy savings performance contract. The evaluation shows that the resulting energy and materials savings will significantly reduce the cost of funding a wide range of projects that will benefit the City for years to come. The preparation of this report would not have been possible without the cooperation of City of Salina personnel. Chevron ES found the entire staff at the City of Salina extremely cooperative and supportive throughout the duration of the Investment Grade Audit. The spirit of cooperation exhibited by the City of Salina staff was instrumental in the successful completion of this Investment Grade Audit and will no doubt contribute to the successful implementation of the projects. Chevron _ Energy Solutions - 1-8 .. . . Section 2 Energy Conservation lMeasures Various energy conservation measures (ECMs) and energy related capital improvement measures (CIPs) were evaluated at the City of Salina. The measures considered covered the categories of building envelope, lighting, water conservation, heating, ventilation, and air conditioning (HV AC), and energy management systems (EMS). Table 2-1 on the following page presents a summary by project type. Table 2-2 presents a summary of costs, consumption savings, dollar savings, and simple payback for each measure. Following Table 2-2 are descriptions for each ECM and CIP with an explanation ofthe existing system operations, and an explanation of how these systems can be modified or replaced to provide more efficient and reliable operation. The primary method utilized for calculating energy and water savings was modeling of the individual ECMs through detailed analysis in spreadsheets utilizing bin weather data, annual load variation, equipment energy use, and schedule parameters. The savings were calculated as the difference between existing equipment definition (efficiencies, full load energy use and capacities, part-load profiles, and operating schedule) and proposed equipment modification or replacement. The type of calculation described above is very accurate for well-defined ECMs. For instance, water consumption savings for domestic water retrofits were determined by individually subtracting the rated water flow ofthe retrofit from the existing fixture water flow. Sample field measurements of existing lighting fixture electric usage were taken to calibrate the manufacturer's data. Chevron ~ 2-1 Energy Solutions . . .

Section 2 Energy Conservation Measures ECM Number: Ll ECM Title: De-lamp and Install Specular Reflectors ECM Description: All nine (9) City of Salina facilities surveyed under the scope of this study utilize light fixtures that operate three or four linear lamps. These fluorescent luminaires are candidates for retrofit with a specular reflector. This ECM considers de-lamping the three or four lamp fixtures down to two 28 watt T8 lamps. This can be achieved without sacrificing light quality by retrofitting the fixtures with enhanced aluminum specular reflectors, and new electronic ballasts. This ECM also considers retrofitting fixtures from two U-tube lamps to two 17 watt T8lamps, reflectors, and new electronic ballasts. There are 866 retrofits included in this ECM. Most of these fixtures have a poor reflective cavity design, resulting in light being trapped in the luminaires and never emerging as "usable" light. This energy is converted to heat within the luminaire, which shortens lamp and ballast life and contributes to additional cooling load. The lighting industry has seen continued advances in the field oflight reflection, which has resulted in the introduction of specular reflectors. With the specular reflector system, up to half of the lamps and ballasts can be removed without reducing the light level at the work surface. Each reflector is custom designed using sophisticated optical engineering and computer-aided design. The reflector is bent at optimum angles for each fixture type. The enhanced aluminum material optimizes reflectivity and overall performance. The reflector produces uniform lighting that is comfortable and aesthetically pleasing without changing the appearance of existing fixtures. Use ofthis reflector causes almost all ofthe light energy within a fixture to be transmitted as usable light. Resulting light levels are less diverse because of the reflector's geometric design. This induces even distribution of light and reduces glare. This ECM will reduce the number of ballasts required to operate the same number oflamps because the older magnetic ballast can operate a maximum of only two lamps, while electronic ballasts can control up to four lamps. With new electronic ballasts, areas that have luminaires mounted end-to-end can be tandem ballasted. Tandem ballasted fixtures house the ballast in one luminaire, while operating lamps in one, or more ofthe nearby luminaires. Due to the significant reduction in the amount of lamps and ballasts to maintain, this lighting ECM will generate considerable maintenance savings. The new lamps and electronic ballasts have average life ratings of approximately 24,000 and 50,000 hours respectively and are guaranteed by the manufacturer for 3 years (lamps) and 5 years (ballasts). Chevron ~ Energy Solutions 2-4 . . . Section 2 Energy Conservation Measures ECM Number: L2 ECM Title: Tl2 to T8 Fluorescent Conversion ECM Description: Eight (8) of the City of Salina facilities surveyed currently utilize fluorescent fixtures that operate Tl2lamps. Standard magnetic core and coil ballasts are used to operate these lamps. This ECM considers retrofitting the existing fluorescent fixtures with T8 lamps and new electronic ballasts. There are 870 retrofits included in this ECM. The combination ofT8lamps and electronic ballasts is one of the most technologically advanced fluorescent lighting systems available. It is proven to be more energy efficient than the conventional Tl2lamps and magnetic ballasts. The electronic ballasts operate at high frequencies to reduce the power requirements, while maintaining the appropriate light level. Electronic ballasts reduce the tendency of fluorescent lamps to flicker or ballasts to hum. T8 lamps use rare earth phosphor minerals, which provide superior color rendition similar to the familiar energy saver or warm white lamps. The combination ofT8lamps and electronic ballasts also operate approximately 30 degrees cooler than comparable Tl2lighting systems, offering the potential for summer cooling savings and longer lamp and ballast life. In addition to energy savings, this lighting ECM creates maintenance savings as well. Magnetic ballasts can control a maximum of two lamps, while electronic ballasts can control up to four lamps, therefore, reducing the number of ballasts to maintain. Some areas that have luminaires mounted end-to-end can be tandem ballasted. Tandem ballasted fixtures house the ballast in one luminaire, while operating lamps in one, or more of the nearby luminaires. Additional maintenance savings will also be achieved by replacing the existing, older lamps and ballasts which may be nearing the end of their useful life ratings. The new lamps and electronic ballasts have expected life ratings of approximately 24,000 and 50,000 hours respectively and are guaranteed by the manufacturer for 3 years (lamps) and 5 years (ballasts). Chevron ~ Energy Solutions 2-5 . . . Section 2 Energy Conservation Measures ECM Number: L3 ECM Title: 32 Watt to 28 Watt Fluorescent Conversion ECM Description: Seven (7) City of Salina facilities utilize fluorescent fixtures containing 32 watt T8 lamps and standard electronic ballasts. A reflector retrofit is not feasible with these fixtures and most contain only one or two lamps. Some of the T8 lamps in these fixtures have burned out or are nearing the end of their lamp life. This ECM considers replacing all the existing 32 watt lamps in one or two lamp fixtures with new 28 watt T8 lamps. The existing electronic ballasts will be re-used wherever possible. There are 507 retrofits included in this ECM. Once a lamp bums out after years of usage, the illuminance that was originally designed for the area is no longer achieved. Light levels lower than the original design can adversely affect workplace efficiency, safety, and productivity. In addition, lamps nearing the end of their life expectancy experience a decrease in efficacy (lumens per watt) which is commonly referred to as lumen depreciation. Depreciated or burned out lamps consume the same amount of energy as a new lamp of the same wattage but produce less light than what was designed. Group re-Iamping ensures the most foot-candles per energy dollar. Group re-Iamping maximizes labor efficiency and reduces the number of workplace interruptions. This ECM ensures lamp continuity throughout the facilities, which will result in all fluorescent fixtures having uniform lumen output, and color temperature. The proposed 28 watt T8 lamps will fit in the existing standard T8 bi-pin sockets without luminaire modification. The new lamps have expected lives of approximately 24,000 hours, and they are 100% guaranteed by the manufacturer for 3 years. Chevron ~ Energy Solutions 2-6 . . . Section 2 Energy Conservation Measures ECM Number: ECM Title: ECM Description: L4 Incandescent to Compact Fluorescent The City of Salina utilizes incandescent light fixtures in many of its facilities. This ECM considers replacing these lamps with new screw-in compact fluorescent lamps. There are 601 retrofits included in this ECM. Incandescent sources provide such desirable qualities as instant light, good color rendition, low replacement cost, and ease of control in dimming situations. However, they are the least efficient type of light source currently available. Of the total input power, only 10% emerges as visible light, 90% is converted into heat energy, which contributes to additional cooling load. The typical efficacy of an incandescent source is 20 lumens per watt and the typical life of an incandescent bulb ranges between 750 and 1,000 hours. Compact fluorescent lamps are a much more efficient light source with the typical efficacy of 50 to 70 lumens per watt, and having an average rated lamp life of 10,000 hours. Long lamp life results in reduced maintenance costs associated with lamp replacements. The higher efficiency, lower wattage compact fluorescent lamps can provide light levels iOf the same intensity as an incandescent lamp up to 150 watts without sacrificing light quality. Chevron ES studied the replacement ofthe 300 watt PAR 56 spotlights currently used at the Salina Community Theater and the Bicentennial Center. A one for one replacement of those particular fixtures with compact fluorescent fixtures is feasible but would sacrifice lumen output and dimming capability. A dimmable compact fluorescent PAR lamp with the equivalent lumen output of a 300 watt halogen lamp is not yet available. This measure does not include or recommend the replacement of those particular fixtures due to their specialized application. Chevron ~ Energy Solutions 2-7 . . . Section 2 Energy Conservation Measures ECM Number: L5 ECM Title: LED Exit Signs ECM Description: A combination of incandescent and compact fluorescent exit signs was found at seven (7) of the City of Salina facilities surveyed. This ECM recommends replacing or retrofitting the incandescent and compact fluorescent exit signs with new light emitting diode (LED) exit fixtures including battery backups. There are 67 retrofits included in this ECM. The typical life of an incandescent exit light bulb ranges from 2,000 to 3,000 hours with an efficacy light source rating of 20 lumens per watt. Of the total input power, only 10% emerges as visible light in an incandescent lamp. Exit signs generally operate 8,760 hours per year; therefore, on average, incandescent exit signs must be re-Iamped as often as 3 times a year, and up to once every 1 to 1 ~ years for fluorescent. Chevron ES recommends replacing these fixtures with a LED exit fixture. LED fixtures meet or exceed standards for exit lighting levels, while using only 2 watts of energy. These LED exit fixtures have a five-year warranty and a twenty-five year projected life. This will reduce nearly all maintenance labor and material costs associated with replacing bulbs. Chevron ~ Energy Solutions 2-8 . . . Section 2 Energy Conservation Measures ECM Number: L6 ECM Title: Metal Halide to New Fluorescent Fixtures ECM Description: Metal halide lamps are currently being used at Memorial Hall in the Arena and Access TV Studio. This ECM recommends removing the 12 existing metal halide fixtures in the Arena and installing 12 new 2'x4' high intensity fluorescent T8 fixtures. This ECM also includes replacing the metal halide fixture in the Access TV Studio with 3 new T8 fluorescent fixtures. There are 15 retrofits included in this ECM. A standard metal halide (MH) lamp provides desirable qualities such as 100 lumens per watt and a lamp life of 15,000-20,000 hours. However, the MH fixture generates a significant amount of heat which adds to the facilities' cooling load. MH lamps also degrade rapidly between 12,000 and 15,000 hours. A typical metal halide lamp has a lumen output depreciation of approximately 40% over its average life rating and are-strike (re-start) time period of approximately 15 minutes. The new fluorescent fixtures use significantly less energy and can generate nearly the same light output as the MH fixtures due to the addition of reflectors. The reflectors in the 2'x4' fluorescent fixtures distribute the light more evenly which minimizes shadows, reduces glare and creates a more balanced brightness. The new fluorescent lamps have a greater average life expectancy of 24,000 hours. In addition, the fluorescent fixtures are instant start (on/oft), and generate substantially less heat than the MH lamps. Fluorescent lamps also produce a constant and more uniform lumen output during an average life cycle in the areas they are used. Chevron Energy Solutions recommends retrofitting the selected metal halide lamps with new fluorescent fixtures with T8 lamps, and electronic ballasts. Due to the quicker re-strike period, constant lumen output, and elimination of heat produced by metal halide lamps, this retrofit is recommended for Memorial Hall. Chevron ~ Energy Solutions 2-9 . . . Section 2 Energy Conservation Measures ECM Number: C1 ECM Title: Networked Programmable Thermostats ECM Description: The Golf Clubhouse, Fire Station No.1, and Fire Station No.2 are equipped with primarily standard, non-programmable thermostats that control their split systems and rooftop HV AC units. The Health Department has a mix of non-programmable and programmable thermostats controlling the split systems. At the Health Department, only one ofthe programmable thermostats was found to have an active set back schedule programmed. This thermostat's clock was set 12 hours in advance, causing the set back temperature to control during the building's occupied hours instead of the unoccupied hours. Other programmable thermostats at the Health Department were programmed with a time schedule, but were set with a constant temperature at every time. If there is a temperature complaint at one of these building, maintenance personnel must physically visit the site to assess the complaint. With a centralized system, much of this time could be used more productively. This measure proposes installing a wireless mesh networked solution from Millennial Net, an industry leader in wireless mesh networking. The wireless system will allow an easy installation, without having to run network cable through the buildings. Each building will have a Wi-Site controller connected to the internet that will communicate with the networked programmable thermostats and the web-based server. The web-based server receives data from each building's Wi-Site; there is no communication initiated from the web-based server to the Wi..Site. There is a monthly fee for hosting the web-based server maintenance of$30/month per site, which is included as a cost (negative savings) in the O&M savings of Table 2-2. This hosting fee includes all programming, scheduling, system monitoring and server maintenance. The proposed networked programmable thermostat system will provide supervisory control of the HV AC equipment at the Salina Community Theater, Golf Clubhouse, Fire Station No.1, Fire Station No.2, and the Health Department. The system will enable the equipment during occupied hours, and the existing local controls will control the equipment to maintain the space temperature set point per the Standards of Control (see Appendix A). The system will allow the equipment to operate during unoccupied hours to maintain a setback temperature. This system will also allow all equipment controlled in these buildings to be monitored via the Internet. Chevron ES has discussed connecting to the Internet with the City's IT Department and found that due to security concerns, the system cannot use the City's existing intranet for access. Since the system is not allowed to connect to the Internet at Fire Stations No.1, No.2, or the Golf Clubhouse via the City of Salina's interface, it is proposed that a cellular Internet connection be used at each of these sites. The estimated monthly cost per site for the cellular connection is approximately $40, which has been included as a cost (negative savings) in the O&M savings column of Table 2-2 for these three buildings. The City may choose from several Chevron U Energy Solutions 2-10 . . . Section 2 Energy Conservation Measures options for the Internet connection, from a standard phone line or dedicated DSL line, or the cellular connection mentioned above. At the Salina Community Theatre and the Health Department, pricing is based on using a direct gateway connection to the existing building's network for Internet access. In addition to the networked programmable thermostats at the Salina Community Theatre, this ECM includes minor ductwork modifications to provide improved control for the tandem air handling unit. This unit serves rooms on all three floors of the building, including the rehearsal room in the basement and offices on the main floor. Thermostatically controlled dampers and a bypass duct with a local pressure-controlled damper actuator will be installed to better manage airflow to these spaces based on occupancy. The fire stations are occupied 24 hours a day, 7 days a week, but opportunity exists for savings when the building is empty while the staff is out on an emergency call or when some areas are unoccupied for extended periods oftime. At Fire Station No.1 and Fire Station No.2, occupancy sensors will be installed for each thermostat to signal the rooftop air handling units to go into unoccupied temperature mode when no occupancy is detected for a period of time. The HV AC equipment will be scheduled according to the occupancy schedule of the spaces, as listed in Appendix A - Standards of Control. It is imperative that maintenance personnel verify the equipment schedules with the occupied schedules at least once a year to maintain the proposed savings. Failing to maintain these schedules will prevent a large portion of the energy savings from materializing. All of the schedules will be adjustable from the central location. The scheduled "ON/OFF" time for most HV AC equipment will coincide with the occupancy schedule for the area served by each piece of equipment. In addition, the City of Salina will need to inform the occupants that the new temperature controls are to be installed; and a procedure for permanent schedule changes and adjusting temperature set points will need to be established. The installation contractor will provide a complete I-year material and labor warranty for all EMS components. Chevron ES will perform a point-by-point commissioning during the installation to ensure that the EMS works properly. The City of Salina will be responsible for the followin2 items: 1. Maintaining temperatures and operating schedules as detailed in Appendix A - Standards of Control of this CEA Report. 2. Maintaining and repairing the thermostats after the I-year material and labor warranty expIres. Chevron _ Energy Solutions ... 2-11 . . . Section 2 Energy Conservation Measures 3. Installing (if extra lines are currently not available) and maintaining a dedicated Ethernet line in each building for the system to have remote monitoring and control capability for the Health Department and the Salina Community Theater. 4. Providing and maintaining dedicated Internet systems for Fire Station No.1, Fire Station No. 2, and Golf Clubhouse. 5. Ongoing monthly fees for remote web-server system. All electrical installations will comply with the National Electric Code, the equipment shall be UL or ETL (or other approved insurance organization) listed, and the overall installation will conform to all Uniform Building Codes. Savings are based on utilizing temperature bin data, and the corresponding occupied and unoccupied hours. The reduction in energy usage was calculated based on shutting offHV AC equipment during unoccupied hours and maintaining a temperature set back/set up. The hours of operation for the existing, and for the proposed changes is located in the Standards of Controls Table, located in Appendix A. Chevron ~ Energy Solutions 2-12 . . . Section 2 Energy Conservation Measures ECM Number: C2 ECM Title: Controls Upgrades ECM Description: The Smoky Hill Museum has an existing energy management system that is working well for the building. The existing energy management system operates the building to maintain the space temperature set point 24 hours a day, regardless of building occupancy to ensure that the exhibits are maintained within desired parameters. During the audit survey, it was noted that several office areas could be set back in unoccupied hours without causing any changes to the temperature and humidity control of the exhibit areas or storage areas. This measure includes programming time for the Invensys representatives to modify the programs to initiate set back during unoccupied hours for the office areas. There are eight (8) variable volume (V A V) reheat boxes serving these dedicated office areas. Implementing a setback program would eliminate excessive heating or cooling of these spaces when unoccupied. Savings are based on utilizing temperature bin data, and the corresponding occupi1ed and unoccupied hours. The reduction in energy usage was calculated based on setting the office area V A V boxes to their minimum position during unoccupied hours and eliminating or reducing the electric reheat coil use. The hours of operation for the existing, and for the proposed changes is located in the Standards of Controls Table, located in Appendix A. Chevron ~ Energy Solutions 2-13 . . . Section 2 Energy Conservation Measures ECM Number: CIPl (not in recommended program) ECM Title: Replace Unit Heaters with Infrared Heaters ECM Description: Five hot water unit heaters provide space heating for the garage/apparatus bay at Fire Station No. 1. One unit heater has been disconnected, but may be used if needed. The unit heaters have a constant flow heating coil, and the fan cycles on and off to maintain the space thermostat's set point temperature. The apparatus bay previously had an ice-melt system for the bay and the adjacent driveway. The ice-melt system has been decommissioned and not used for several years. The hot water boilers serving the building were sized for the loads of the unit heaters and the ice-melt system. With the ice-melt system no longer in use, the boilers are oversized for their current load -- the four working unit heaters. Existing Unit Heater This measure proposes abandoning the existing two hot water boilers in place, removing the unit heaters, demolishing the existing hot water piping in the apparatus bay and equipment room, and installing five new gas-fired infrared unit heaters to serve those spaces. New gas lines, gas exhaust pipes and electrical power will be provided for each new infrared heater. Coring or drilling through the walls and/or roof for the new exhaust pipe and gas pipe as required is included in the budget. Included is replacement of the electrical disconnects and breakers based on using the existing electric panels and available capacity. No new electrical panels or circuit breaker panels are included in the price. Proposed Infrared Heater In the heating season, opening the garage doors allows a substantial amount of cold outside air into the building. End-switches will be provided for the infrared units located near garage doors to prevent their use when the garage doors are open. With an infrared system, the floor and occupants are warmed by the radiant heat instead of the air. Ceiling space is at a premium in the apparatus bay at Fire Station No.1. Chevron ES recommends installing two of the heaters in the rear ofthe apparatus bay and one in the equipment room (small garage). The finaI arrangement will be determined during engineering design. Savings for this measure were calculated based on improved combustion efficiency of the radiant heaters at full and part loads over those of the existing atmospheric boiler; elimination of distribution losses with the hot water piping; and shutting offunits at times of wasted heating such as when garage doors are opened. The calculated savings were compared for reasonableness to the existing heating load as established from the most recent 12 months of natural gas usage data. Chevron ~ Energy Solutions 2-14 Section 2 Energy Conservation Measures . ECM Number: CIP2 (not in recommended program) ECM Title: Replace Boiler ECM Description: The boiler at the Police Administration Building is near the end of its rated useful life, and is oversized for its current load. The boiler was originally designed to provide hot water for heating to the air handling units, as well as floor radiant heat to the former jail/holding area. The floor radiant heat was eliminated several years ago when the space was converted to more evidence storage. At Fire Station No.2, the boiler is over 50 years old, and is at the end of its rated useful life. This cast iron boiler has an atmospheric burner, which has a standing pilot liight that burns whether the boiler is firing or not. This boiler was also originally designed to provide floor radiant heat to the first floor, as well as to hot water radiators throughout the building. When the building was remodeled (around 2006), the floor radiant heat was disconnected along with the radiators on the upper floor. Only the hot water unit heaters in the apparatus bay and three hot water radiators on the ground floor remain in service. . Police Administration Building Boiler This measure includes replacing the existing boiler at the Police Administration Building with a more efficient boiler with similar capacity, to ensure adequate capacity is available if measure M5 is selected. If the City of Salina chooses to implement measure M5, the additional outside air required to ventilate the building would likely result in increased heating consumption. This measure also includes replacing the existing boiler at Fire Station No.2 with a slightly smaller higher efficiency boiler. For both buildings, new PVC fresh air intake and exhaust will be routed from the basement to the outside wall. A new concrete curb will be added, the existing hot water pumps and valves will be reused. One new boiler control valve is included for each boiler. The new boilers will need power for the combustion fan and burner controls. Included in the pricing are new breakers based on using the existing electric panels and available capacity. No new electrical panels or circuit breaker panels . Chevron ~ Energy Solutions Fire Station #2 Boiler 2-15 . . . Section 2 Energy Conservation Measures are included in the price. A new boiler kill switch will also be installed for each boiler. At both facilities, the existing air separator and expansion tanks will be reused. Savings for this measure were calculated based on applying the efficiency of the new boilers to the existing building heating load for each building, which was based on the most recent 12 months of natural gas usage data at each building. Chevron V Energy Solutions 2-16 . . . Section 2 Energy Conservation Measures ECM Number: CIP3 (not in recommended program) ECM Title: Replace Condensing Unit(s) ECM Description: The Golf Clubhouse has a General Electric brand condensing unit that is at the end of its rated useful life. This condensing unit provides cooling for the south portion of the building. At the Health Department, the six (6) existing Lennox condensing units serving the north side ofthe building are all 14 to 15 years old, and are rated at 10 SEER or below. This measure includes replacing these existing condensing units with new, more efficient condensing umts. The new condensing units will be rated at a minimum of 14 SEER. Existing refrigerant lines will be reused as much as possible. New connections to the new condensing units are included in the price. Insulation on the exterior portions of the new refrigerant line connections will be installed. Existing coil drains and routing will be reused. Included is replacement of the electrical disconnects and breakers based on using the existing electric panels and available capacity. No new electrical panels or circuit breaker panels are included in the price. New air hoods on the proposed Golf Clubhouse units are not included. Modifications to the existing CU enclosure at the Golf Clubhouse are not included. The new condensing units will utilize refrigerant R22 to match the existing air conditioning coil on the inside unit. The inside furnaces and air conditioning coils on the existing units at both the Health Department and the Golf Clubhouse are all 14-15 years old, but are in very good condition, and all units at the Health Department have high efficiency heaters. Savings for this measure were calculated using cooling load variation with each annual temperature bin. Existing and proposed condensing unit efficiencies were applied to the existing load; the energy savings is the difference between the existing and proposed energy usage. The new unit efficiencies were based on 14 SEER for the condensing units at the direction of the City of Salina. Golf Clubhouse Condensing Unit Heat pumps were considered for this measure but are not recommended due to the increased cost of the heat pump installation as compared to the cost of a high efficiency condensing unit, coupled with the fact that the heat pumps are slightly less efficient than the proposed condensing units. Chevron ~ Energy Solutions 2-17 . . . Section 2 Energy Conservation Measures ECM Number: CIP4 ECM Title: Replace Split-System Units ECM Description: The south portion of the Health Department building is conditioned with five olde:r split systems, each consisting of a furnace with cooling coil in the attic and a condensing unit mounted on the roof. These five (5) split systems are near the end of their rated useful life, and are not operating efficiently. The existing furnaces have standing pilot lights which use gas year round, regardless of need. Due to their age and use, the condensing units for cooling are operating at lower efficiencies than current design condensing units. These five split systems do not provide fresh outside ventilation air for the occupants of the building as typically required by current building codes. This measure proposes removing the existing five split systems and replacing with five new, more efficient units. The new split systems will have outside air ducted to them to provide ventilation, new spark- ignition furnaces, and high efficiency condensing units. Adding the code-required ventilation will cause an increase in energy required to heat and cool the air, and this increased usage is included in the energy use shown on the ECM Summary Table. Each outside air damper will be mechanically interlocked with its corresponding supply fan to open when the fan is operating and close when the fan is off. A labor premium for attic: work was included in the price for this measure, and a new access ladder similar to the ladders installed for the south end attic mechanical rooms will be installed. Furnace #1 at Health Department The existing condensing units utilize R22, and the proposed condensing units will use R41Oa. Changing the condensing unit's refrigerant type would typically require changing the inside coil and possibly refrigerant lines to match the pressure rating of the new refrigerant. Replacing the R22 condensing unit to an R410a condensing unit is not usually cost effective as a stand alone measure when the inside coil must be replaced also. Replacing the entire five split systems affords the City of Salina on opportunity to switch refrigerants to the future refrigerant replacement for R22 now. New balancing dampers will be provided in main branch lines to enable balancing air flow. The existing ductwork and diffusers will be reused. Outside air or ventilation ductwork will be routed from proposed new outside air louvers (to be located in the attic space) to each new split system. New refrigerant lines will be run from the new condensing units to the inside furnaces. Existing coil drains and routing will be re-used. Included is replacement of the electrical disconnects and breakers based on using the existing electric panels and available capacity. No new electric panels or circuit breaker panels were included in the price. Chevron _ Energy Solutions ... 2-18 . . . Section 2 Energy Conservation Measures Savings for this measure were calculated based on temperature bin data to determine the existing load and the proposed load of the new units with the addition of the outside air. Existing split system heating efficiencies and condensing unit efficiencies were applied to the existing load; proposed heating efficiencies and condensing unit efficiencies were applied to the proposed load. The new unit efficiencies were based on a minimum 14 SEER for the condensing units, and 90% for the new gas furnaces. Heat pumps were considered for this measure but are not recommended due to the increased cost of the heat pumps compared to the cost of a high efficiency condensing unit coupled with the fact that the heat pumps are slightly less efficient than the proposed condensing units. Chevron V Energy Solutions 2-19 . . . Section 2 Energy Conservation Measures ECM Number: CIP5 ECM Title: HV AC Improvements/Controls Upgrade ECM Description: The air handling units (AHUs) serving the Police Administration building are the original equipment installed when the building opened in 1969. These existing air handling units are multi-zone units, which mix a stream afhot air and cold air ta deliver the required temperature air to each zone. The zone mixing dampers are nat accessible far maintenance and, as such, may not be working effectively. The hat and chilled water cails in these units have canstant flow and no contral valve to vary the flow as laad changes. Instead, each zone damper modulates to blend the amaunt of hat and cold air required for its zane. The use af various spaces in the building has changed over the years, and the current air distributian system is not as effective as it shauld be. In the winter, some exteriar rooms do nat get enaugh heat and in the summer, some interior spaces are toa warm. This building has been a problem far the city maintenance staff for years. Chevran ES recommends replacing the 3 existing air handling units with variable air volume air handling units and electric zone reheat cails ta provide the best cantrol and comfort far the occupants. The existing air handling units will be remaved from the building, and replacement air handling units will be installed. The new air handling units will each be equipped with a supply fan and assaciated VFD, hat water preheat and heating cails, and a chilled water coil. The: new AHUs will alsa have full economizer capability, but will not have a dedicated return fan. Temporary heating and caaling units will be used to serve the spaces during construction, as required. Same ductwork may need ta be replaced, but the majority af the existing ductwark will be reused; the engineering design phase will determine to what extent the ductwork needs to be madified or replaced. A new stand-alone energy management system far HV AC contral will be installed as part afthis project and is included in the cost estimate. Canverting from a constant volume air handling unit to a variable valume air handling unit typically generates significant energy savings. Currently, at the Police building, the outside air dampers are closed in the winter and summer in arder to meet space temperature requirements. With the new air handling unit installation, more outside air will be introduced into the building in order to meet building code ventilation requirements. Caaling and heating this additiana1 autside air has a negative impact of the energy savings, but will provide improved occupant comfort. The addition of terminal reheat cails will alsa increase the energy usage, but these provide the mast cast-effective way to solve the comfart and cantra1 problems in this building. Chevron U 2-20 Energy Solutions . . . Section 2 Energy Conservation Measures The building load model will be refined during the engineering phase of the projec:t to accurately determine load and airflow requirements for the building. In order to complete the computer model, additional data and site work to determine how effectively the conditioned air is being delivered to the spaces now may be required before the detailed scope can be finalized. For instance, more ductwork modifications, or increased duct sizes may be required pe:nding the analysis. Material and labor costs for these potential changes have been incorporated into the budget pricing for this ECM. In order to install the electric zone reheat, an electrical service upgrade will likely be required. A budget for the electrical upgrade has been included in the cost estimate. The need for the electrical upgrade and a firm quantity for the work will be determined during the engineering phase of the project. The City of Salina has indicated that their asbestos testing shows no asbestos in the corridor ceilings where the majority of the ductwork is located. Any asbestos testing or abatement required is not included in this scope of work. Chevron ~ 2-21 Energy Solutions . . . Section 2 ECM Number: CIP6 Energy Conservation Measures ECM Title: Remove Skylight ECM Description: The Health Department building has a large skylight in the lobby area. The City of Salina indicated to Chevron ES that the skylight has developed leaks over the past several years, and would like the skylight removed. The City allocates funds to their budget on a yearly basis to caulk and seal around the skylight. The Health Department provides and replaces a sun screen every 2-3 years. Existing Sunscreen This measure recommends removing the existing skylight and installing a new roof structure and TPO roof to match the existing roof material. Rigid roof deck insulation will be installed and a new drop ceiling will be added, with batt insulation above the ceiling tiles. The existing cove lighting and air diffusers are located below the proposed drop ceiling height, and may be suitable for reuse. For safety reasons, this work will need to happen when the building is unoccupied, and a labor premium for evening or weekend work has been included in the budget. Savings for this measure result from the reduction in solar load with removal of the skylight, and from the increased thermal resistance of the new roof and ceiling structure. Temperature bin data was used to account for annual load variations. Chevron U Energy Solutions Existing LoveLighting and Skvlieht 2-22 Section 2 . Energy Conservation Measures ECM Number: CIP7 (not in recommended program) ECM Title: Ceiling Modification/Insulation The Police Administration Building has a large office on the top floor with skylights and clerestory windows around the perimeter. This area was the old courtroom, and is now the Chief of Police's office, secretary's office, and conference area. Due to the high ceilings, low airflow, and insufficient roof insulation, this space is difficult to keep comfortable year-round. The City of Salina has indicated that their asbestos testing shows positive results for asbestos in the ceiling of this room and provided a contractor estimate to abate the area of work. The cost of this abatement is not in Chevron ES' scope of work, but is included in the financial analysis of the project for direct contracting by the City of Salina. This scope of work is dependent upon having the asbestos removed. ECM Description: . Clerestory Windows in Chief of Police Office This measure recommends installing a new drop ceiling with additional insulation above the new ceiling tiles. To keep some of the natural sunlight, 4 Solatubes or equivalent brand will be installed in the existing skylight wells and routed to the new drop ceiling. The remaining skylight glazing not replaced with Solatubes will be removed and weatherproofed. The existing air diffusers are located below the proposed drop ceiling height which is just below the clerestory windows level with the ledge shown in the picture, and the existing diffusers will be blanked off. The ductwork will be Solatube routed to the new drop ceiling and new diffusers will be installed. New recessed troffer lighting fixtures will need to be installed in the drop ceiling to replace the existing lighting fixtures on a one-to-one basis. Savings for this measure were calculated based on using temperature bin data and the reduction in load due to the increased resistance of the new roof and ceiling structure. . Chevron ~ Energy Solutions 2-23 Section 2 Energy Conservation Measures . Water ECMs WI through W5 The City of Salina uses few low consumption water devices in the facilities surveyed under the scope of this study. The facilities use more water than necessary due to the inefficient manner in which the existing devices distribute water. In many areas of the country, the use of water has become more of a concern in recent years due to depletion of natural raw water sources, deterioration of water infrastructure, and environmental concerns, all resulting in e:scalating cost of water and sewer rates. Utility charges for potable water and sewage is now increasing at a rate greater than other utilities such as electricity and natural gas. Chevron ES proposes a comprehensive program of water conservation that includes all areas of consumption in the buildings. The proposed changes fall directly in line with the City's Strategic Plan for 2008, specifically goal #7: "The City will recognize the importance of its natural resources and make practical efforts to preserve them." Action item #1 of goal #7 states that the City is planning a comprehensive approach to water use and conservation, which our project provides for the buildings included in our scope. On the following pages are details of the proposed Energy Conservation Measures (ECM) for all . facilities surveyed. . Chevron U Energy Solutions 2-24 . . . Section 2 Energy Conservation Measures ECM Number: WI ECM Title: Replace Faucet Moderators ECM Description: All City of Salina facilities surveyed contain kitchen and lavatory faucets that are designed to mix hot and cold water to the desired temperature. All faucets surveyed deliver water through moderators with internal parts that have deteriorated over time. These moderators allow a higher than necessary flow rate for their particular application. On average, these fixtures flow rates are approximately 3 to 4 gallons per minute. There are 143 retrofits included in this ECM. This ECM recommends replacing worn or damaged moderators with new pressure compensating moderators that utilize an o-ring to deliver the proper water flow rate for the task for which the faucet was designed. For lavatory faucets, existing moderators shall be replaced with 0.5 gallon per minute moderators. Kitchen faucet moderators shall be replaced with 1.5 gallon per minute moderators. This ECM also recommends replacing the o-rings, washers, and packing for faucets that are leaking. These upgrades will decrease water consumption, sewer, and maintenance costs. Since a portion of the water saved will have been heated, thermal energy will also be saved. Automatic sensors for faucets were considered, but are not included in this project due to the increased maintenance cost to replace batteries and adjust the sensors. Hard-wired sensors were not considered due to the substantial cost of running power to each fixture. Chevron !IIII!!!!! Energy Solutions - 2-25 . . . Section 2 Energy Conservation Measures ECM Number: W2 ECM Title: Replace Toilets ECM Description: All facilities surveyed contain toilets and flush valves that are not rated for low water consumption. These flush valves will occasionally hang up, using an excessive amount of water. In most cases, the diaphragms and vacuum breaker's rubber internal part will start to deteriorate after five years which can cause leaks that are not easily detected. These flush valves use between 3 to 5 gallons per flush, depending upon type. Recent technology has helped manufacturers develop toilets and flush valves that eliminate waste more efficiently. There are 146 retrofits included in this ECM. The Federal government established the Energy Poliey Act of 1992 (EPAct), a national policy that required by 1997 that all new water closets use no more than 1.6 gallons of water per flush. Since that time, water closet manufacturers have redesigned their china to effectively complete the flush process with 1.6 gallons or less. This ECM recommends replacing the inefficient toilets at all facilities surveyed with new, low water consumption toilets that exceed the EP A requirements. Since the existing toilets are not designed for low water consumption, they must be replaced along with their flush valves. Retrofit kits for flush valves shall be used where low flow toilet china already exists. These retrofit kits convert the existing 3 to 5 gallon per flush valves to 1.28 gallons per flush. Toilets with tanks that usually use 3.5 gallons per flush will be replaced with new tank toilets rated at 1.0 gallon per flush. All ADA compliant toilets will be replaced with new ADA compliant toilets. At the Bicentennial Center, the pricing includes installation of an access door to the pipe chase. The access door is required for the modifications to the flush valves. Automatic sensors for flushometers were considered, but are not included in this project due to the increased maintenance cost to replace batteries and adjust the sensors. Hard-wired sensors were not considered due to the substantial cost of running power to each fixture. Chevron ~ Energy Solutions 2-26 . . . Section 2 Energy Conservation Measures ECM Number: W3 ECM Title: Retrofit and Replace Urinal Flush Valves ECM Description: The existing urinal flush valves located at all City of Salina facilities are from five to fifteen years old. Due to the age and condition ofthe flush valves' internal parts, these valves use approximately 2 to 3 gallons per flush. These flush valves will occasionally hang up, using more water than required. The flush valve diaphragms and vacuum breaker's rubber internal part will start to deteriorate after five years which can cause leaks that are not easily detected. There are 55 retrofits included in this ECM. The Federal government established the Energy Policy Act of 1992. (EP Act), a national policy that required by 1997 that all new urinals use no more than 1.0 gallon per flush. Since that time, urinal flush valve manufacturers have designed 1.0 gallon per flush retrofit kits for urinal flush valves. This ECM recommends the installation of retrofit kits to the existing flush valves. These retrofit kits which include spuds, handle kits, vacuum breakers, water saving diaphragms and o-rings will reduce the 2 to 3 gallons per flush valves to 1.0 gallon per flush and eliminate wasteful leaks. This upgrade will result in a reduction of water consumption and sewer costs. The standardization of all flush valves and newer internal parts will lower maintenance costs. Chevron ~ Energy Solutions 2-27 . . . Section 2 ECM Number: W4 ECM Title: ECM Description: Energy Conservation Measures Replace Faucet and Spray Valves This ECM includes replacement of an older lavatory faucet at Smoky Hill Museum with a new, more efficient push-button faucet. This ECM also includes replacement of the dishwashing spray valves at the Bicentennial Center. There are 4 retrofits included in this ECM. These upgrades will decrease water consumption, thermal energy, and will reduce maintenance cost. Applicable sewer costs will also decrease in proportion to the decrease in water usage. Chevron ~ Energy Solutions 2-28 . . . Section 2 Energy Conservation Measures ECM Number: W5 ECM Title: Replace Water-Cooled Ice Machines ECM Description: This ECM considers replacing the existing ice machines located at Fire Station No. 1 and the Golf Clubhouse with newer ice machines that utilize air cooled condensers. The existing ice machines currently utilize water cooled condensers. The existing water cooled condensers consume more than ten times the amount of water required for actual ice production. There are two retrofits included in this ECM. The main benefit for replacing the existing ice machines is water savings, but maintenance savings can also be realized since water cooled condensers generally require more maintenance than air cooled condensers. Savings for this measure result from the elimination of water use to cool the ice compressors. The electrical penalty for switching to air- cooled vs. water cooled was calculated based on manufacturer's data and data loggers for run-time from a previous job. Chevron ~ Energy Solutions 2-29 . . . Section 2 Energy Conservation Measures ECM Number: VI ECM Title: Contract Natural Gas ECM Description: Kansas Gas Service (KGS) furnishes natural gas for all buildings in the scope of the project, except for the Health Department and Smoky Hill Museum. The Health Department obtains natural gas under a contract that Saline County has with Seminole Energy Services. With contracted natural gas, the Health Department has realized a lower natural gas rate than paid for use at the City buildings. Refer to Section 3, Historical Energy Consumption for comparison of rates. The ECM proposes contracting natural gas for the Bicentennial Center, the Memorial Hall, and the Police Department. With contracted natural gas, a third party would supply the commodity and Kansas Gas Service distribution would provide delivery services within the City. The reason that only these three buildings are recommended is because ofthe restrictions of Kansas Gas Service for delivery ofthe natural gas. To qualify for delivery of natural gas from a third party, a minimum annual usage of 1,500 mcf per building or contiguous properties is required. (See KGS's Small Transport Service tariff in Appendix D) The annual usage at the Bicentennial Center and at the Memorial Hall each exceeds the 1,500 minimum. In discussions with KGS, the Police Department building is considered to be contiguous to the Memorial Hall. Chevron ES explored allowing Fire Station No. I to be considered contiguous to these buildings also, but KGS commented that since other properties separate Fire Station No. I from Memorial Hall or the Police Department Building, that it would not qualify. Contracting third party natural gas supply does not guarantee a lower rate each month, but over time this approach has been shown to reduce annual natural gas expenses. Different approaches can be taken to contracting the gas by locking in annual rates for a fixed amount or by buying each month at the "first of month" price. When a price is set, typically an amount of usage is also defined. When more or less than the contract amount is used, the excess or overage will be charged at a different rate. Chevron ES will work with the City's procurement department to assist in evaluating historical usage and purchasing options. To estimate savings, Chevron ES was furnished the historical rates from Seminole Energy Services for the last two years. These rates were compared to the commodity portion ofthe historical natural gas bills from KGS, shown in Table CI of Appendix C. In addition to the commodity, KGS Small Transportation Service tariff for delivery has a small discount over the delivery rate in the General Sales Service tariff now used with KGS supply. These comparisons, shown in Table C2 of Appendix C, show the result of an average savings of $2. 792/mcf for the period from September, 2006 through May, 2008. This is based on all usage of the buildings being charged at the "first of month" rate over by Seminole Energy Services. It is rather optimistic to assume that each month's usage can be predicted accurately, so there will be some Chevron ~ Energy Solutions 2-30 . . . Section 2 Energy Conservation Measures influence of excess or under usage, which can change this savings rate. To check this, Chevron ES compared the historical Seminole Energy Services blended rates to the commodity portion paid by the Health Department. This comparison is shown in Table C3 in Appendix C, indicating a historical savings over use of KGS gas of $2.1 08/mef for the same September, 2006 through May, 2008 period. This equates to 74% ofthe analysis using only the "fIrst of month" rates. Chevron ES proposes that forecasted natural gas cost savings be based on a natural gas savings rate of $2.1 O/mcf. This amount is then multiplied by baseline natural gas usage at the buildings less any natural gas savings from implementation of ECMs. The baseline usages are shown in Section 3 - Historical Energy Consumption. Chevron ~ Energy Solutions 2-31 . . . Section 2 Energy Conservation Measures ECM Number: U2 ECM Title: Consolidate Gas Meters ECM Description: The Golf Clubhouse has two natural gas meters -- one serving the usage of the furnaces and domestic hot water on the south portion of the building, and the other serving the lightly used north "First Tee" area furnaces. As the north meter only serves the heating needs of the north furnaces, it typically has zero use at least five months per year. Evenso, the City incurs a service charge and fee on this meter of$23.52/month with no usage. This ECM proposes consolidating all natural gas use of the Clubhouse onto the south gas meter. This includes the addition of natural gas piping from the south furnace room to the north furnace room. This piping will be routed above the drop ceiling across the rooms between the two furnace rooms. Kansas Gas Service will remove the unused meter back to the gas main. NOTE: The gas utility information furnished by the City included data for two additional meters at the Golf Course, but not serving the Clubhouse. These meters showed as much or more use as the Clubhouse gas use, including use throughout the summer. One of these meters was identified as serving the North Maintenance building. As other buildings at the Golf Course were not in the contract scope, the source of the natural gas use at these other Golf facilities was not investigated. Chevron ~ Energy Solutions 2-32 . . . Section 2 Energy Conservation Measures Energy Conservation Measures Not Recommended This section provides a brief description of energy conservation measure projects that were evaluated or considered, but later found not to be economically viable. While these projects may offer some energy savings, they typically would have to be funded through an additional capital outlay and/or through excess savings from other projects. Title: Controls Upgrade Description: The Bicentennial Center has a supervisory local control system for some of its HVAC equipment. Every air handling unit cycles to maintain the space temperature set point when operating. Due to the sporadic occupancy at the building, the maintenance staff have been manually duty cycling or alternating run times for the arena area of the building -- only half of the units run when the building is not hosting an event. Some of the local controls: that Chevron ES personnel observed during our survey did not appear to be operational or could not be confirmed due to inaccessible outside air dampers or bypass dampers. From the temperature readings observed, it is likely that the majority of the outside air dampers were closed. This measure is not recommended due to the high cost to install a new controls system and the negative payback resulting from increasing the outside air usage when the building operation is conformed to building codes. Title: Install Trash Compactor Description: The Smoky Hill Museum has six roll-off trash carts that are serviced weekly. The building has sporadic use, and does not always use all six containers each week. The City is charged for picking up all six containers whether they are all used or not. Chevron ES investigated installing a trash compactor as well replacing the trash carts with a single trash dumpster. The trash dumpster offered a potential savings of $30 per month over the use ofthe six carts. Chevron ES found that the savings available with the large dumpster were offset by the cost of the required concrete slab and enclosure fence. Title: Replace Condensing Units Description: The Salina Community Theatre has some older condensing units that provide cooling for the ground floor restrooms and the green room. Chevron ES discovered that due to the small size and intermittent loads in these spaces, replacing these units with modem high efficiency units was not cost-effective and is not recommended. Chevron ~ Energy Solutions 2-33 . . . Section 2 Energy Conservation Measures Title: Replace Stearn Boiler and Re-Zone Piping Description: The Memorial Hall has a small stearn boiler that installed in 1993-1994, with a new condensate return system installed in February of2008. The boiler is rated at 15 psi operating stearn pressure, but currently operates at 3 psi to maintain the space temperature set point of the single controlling thermostat in the lobby. The boiler stearn serves several original stearn radiators throughout the building. Some of the radiators are equipped with occupant controlled thermostatic regulating valves, which help control the temperature in that space. Although the boiler was installed after many of the building's original stearn radiators were taken out of service, it is still oversized for the current load, and operates inefficiently to maintain such a low stearn pressure. Chevron ES considered replacing the stearn boiler with a smaller, more efficient stearn boiler, and re-zoning the existing stearn piping to enable better control of the building heat and temperature setback when the building or portions of the building are unoccupied. This measure is not recommended due to the long payback of replacing the boiler and modifying the piping. Savings for this measure would be negatively impacted by the pending planned renovations in the ACCESS TV studio area, wHich would reduce the building stearn load. Chevron ES recommends a planned removal of the stearn systems in the building, and replacing with either a hot water system or packaged heat pumps similar to the planned renovations of the ACCESS TV studio. Title: Replace Window Air Conditioning with Centralized Cooling Description: The USD 350 offices on the south end ofthe Memorial Hall building use window air conditioners to provide cooling, while stearn radiators supply heat. Chevron ES considered replacing the window air conditioners with packaged AC units and installing duct\;vork to better distribute airflow to the spaces. With the change to a packaged unit, more space in the affected rooms would be cooled than are currently being cooled with the window air conditioners, which would offset any savings with the more efficient AC system. Architectural modifications to the space would be required to allow for installation of the ductwork to maintain an aesthetically pleasant work environment. Due to the limited occupancy of the areas using window air conditioners, their intermittent use, and the resulting long payback, this measure is not recommended. Chevron ~ Energy Solutions 2-34 . . . Section 2 Energy Conservation Measures Title: Install Arena Ceiling and HV AC Description: The arena at Memorial Hall currently houses a local youth gymnastics program. The gymnastics program holds several meets and public events throughout the year with a full audience in attendance. The arena currently has no cooling, and limited heating capability. These events would be more comfortable for the gymnasts and their audience if the space were air conditioned. The City of Salina asked Chevron ES to investigate installing a drop ceiling over the arena area, and installing heating and cooling to serve the space. Further discussions with the City indicated that the work at the Police Department building (ECM M5) was of higher priority than upgrading Memorial Hall. As this project would increase energy use and ECM M5 was a priority, focus was place on development ofECM M5 for use of excess savings generated from the other City projects in the program. The City confirmed that there would be no increased revenue generated by making the proposed changes and agreed that the measure should not be included in the project due to the increased operating cost and lack of any additional economic benefit. Title: Downsize Water Meter Description: The Memorial Hall has the largest water meter of the nine buildings in scope, yet it has an annual usage equivalent to buildings with only a 1" to 2" meter. The Memorial Hall's peak monthly water usage is less than that of the Golf Clubhouse, which has a 1" water meter. \Vith the upcoming water rate changes, the 3" meter will incur a service charge of $63. 15/month. A 1 W' meter's service charge is to be $14.89/month. With a change to a more appropriately sized water meter, the Memorial Hall could realize an annual reduction of up to $579. Chevron ES has discussed this matter with the City Municipal Utilities Department and they are investigating the feasibility of a meter changeout to reduce costs at the Memorial Hall. But, as of the issuance of this report Chevron ES was unable to get a conclusive answer to this request. As such, this ECM has been left under "Not Recommended". Chevron ~ Energy Solutions 2-35 '. . . Section 3 Historical Energy Consumption Historical Energy Consumption The consumption and costs of electricity, natural gas, water and sewer historical usages for the nine City of Salina facilities affected by the scope are provided in this section. The purposes of presenting historical energy consumption and costs are to calibrate energy savings calculations, to determine a basis for which energy savings can be evaluated, and to establish baselines for future savings reference. The following pages include electric, natural gas, and water consumption histories. The electric, natural gas, and water rate tariffs are provided in Appendix. D. Approx.imated overall energy use of the nine City buildings are given in the below chart: Energy Load Summary III Lights - 9% . Cooling - 26% o HV AC motors - 13% o Plug Loads - 15% .

Section 3 Historical Energy Consumption All buildings, except the Bicentennial Center, have electrical usage charged under Westar Energy's Small General Service (North Area) tariff. Under the Small General Service (SGS) rate, the first 1,200 kWh on monthly consumption is charged at a higher rate than all remaining consumption for a month. The SGS rate structure also has a demand charge for the maximum demand usage over 5 kW in each month. While the consumption charge is constant throughout the year, the demand charge changes seasonally with a summer (June through September) rate that is more than twice the non-summer demand rate charge. In addition to the energy rate and demand charges, there is a fixed $12 customer charge, several riders that are a function of consumption, and a 5% franchise fee that varies with the total charge of each month's bill. The Bicentennial Center electrical usage is charged under Westar Energy's Medium General Service (MGS) tariff. This tariff is available for facilities with demand use over 200 kW. The MSG tariff offers lower consumption rates than the SGS tariff, but a constant yearly demand rate. The summer (June through September) consumption rates are slightly higher than the non- summer consumption rates. The MGS tariff also has a monthly fixed charge of $1 00, several riders that are a function of consumption, and a 5% franchise fee on the total charge of each month's bill. The electrical rates used in the savings calculations are based on the most recent tariff rates. As the amount of the riders can vary each month, the actual total charge per kWh varies from month to month, primarily due to Fuel Charge Surcharge, which has been trending higher over the past six months of available data. All buildings use substantially in excess of the 1,200 kWh tier of the SGS tariff, so the lower tier energy charge is used in the determination of the impact of energy savings measures at the buildings. For the rates to be representative ofthe charges at the time of implementation, the impact of the Westar Energy rate increase application is included. (See Appendix D.) Table 3-2 Electrical Consumption Rate Determination Base Tariff Surcharges Franchise Expected Total Rate E1ffective Rate ($/kWh) ($/kWh) Fee Increase ($/kWh) SGS - all months $0.022923 $0.02060 5% 15% $0.0526 MGS - June-Sept $0.016367 $0.02122 5% 15% $0.0454 MGS - Oct-May $0.01211 $0.0402 Surcharges are based on sum ofthe average ofthe Fuel Charge, Property Tax Surcharge, Transmission Service Charge, and Environmental Cost Recovery Rider over the last twelve billing cycles. The effective electric demand rates are not impacted by any surcharges or riders. Chevron ~ Energy Solutions 3-2 . . .

This was not always the case for all buildings at the City of Salina but, with a few exceptions, there was reasonable agreement on electric consumption from year to year. To represent recent electric growth and to smooth out minor anomalies, the average of the most recent two years of data was used to establish the historical baseline for each building. One exception to this is in the data for Fire Station No.2, which shows a significant drop in electric usage for most of 2006. This was identified as the time that the fire station was being renovated.

The Golf Clubhouse has two natural gas meters, so the bills for these two monthly bills were aggregated for the analysis. The average natural gas rate for each of the months from June, 2007 through May, 2008 was determined and averaged. Because of the upward trend in natural gas costs, the most recent data is the closest to representing where gas rates may be today. The averages from the seven buildings were quite similar, varying only because of the billing periods that kept the monthly bills from using the same surcharges and gas costs. A rate of $11.617 fmcf was used as the basis for the savings calculations for the seven buildings using a twelve-month average. Chevron ~ Energy Solutions 3-13 . . .

The new water rate structure along with new water rates increases in sewer rates, and increases in meter charges go into effect November 1, 2008. Resolution 08-6523 also sets the water, sewer and meter rates for five years. These rates are shown in Table 3-25. The water and sewer savings rates used in the savings calculations are based on the 2009 rates. The average escalation of total rate per ccf over the next five years is 9.0%. Table 3-25 Water and Sewer Rates per Resolution 08-6523 2009 2010 2011 2012 2013 Average annual rate of increase Water base rate ($/ccf) $2.34 $2.55 $2.82 $3.12 $3.49 10.5% Water excess rate ($/ccf) $4.68 $5.10 $5.64 $6.24 $6.98 10.5% Sewer ($/ccf) $2.88 $3.08 $3.35 $3.64 $3.90 7.9% For each building, monthly baseline water use was established using the averages from 2005 through 2007, using all available data furnished by the City. To determine effective combined water and sewer rate for each building, a forecast was developed for post-retrofit water use. It is assumed that, on average, each month's future usage is at this post-retrofit value. Knowing the post-retrofit usages, the months exceeding 120% of the "Winter Quarter Average" can be Chevron . Energy Solutions 3-23 . . . Section 3 Historical Energy Consumption determined. The water savings in these months is based on the "excess use" rate and the water savings in other months is based on the base rate. Each month's rate is weighted by the monthly forecasted quantity of water savings in ccf to arrive at an equivalent annual average water rate. All usages also have a $0.032/kgal ($0.023936/ccf) charge for the state water fee and for sewer usage for the types ofECMs considered; For 2009, the minimum base savings rate is: $2.34/ccf(water) + $2.88/ccf(sewer) + $0.02394/ccf(state fee) = $5.244/ccf The maximum savings rate for any month occurs when usage exceeds 120% of the "Winter Quarter Average": $4.68/ccf(water) + $2.88/ccf(sewer) + $0.02394/ccf(state fee) = $7.584/ccf The savings rates fall in between these values for all buildings as shown in the ECM Summary table of Section 2. Note that the savings rates at the Golf Clubhouse and at Smoky Hill Museum are at the minimum rate of $5.244/ccf as each month's post-retrofit usage is expected to be below 120% of the defined minimum "Winter Quarterly Average" of 800 ccf. Another interesting observation is that the Police Department savings rate is near the maximum rate year-round. This is because of the shape of the annual water use curve which shows that the three minimum use months are coincident with when the "Winter Quarter Average" use is established. A summary of the historical water usages are given in Table 3-26 through Table 3..34 along with the three year historical average usage. Chevron ~ Energy Solutions 3-24 . . .

Section 4 Operation & Maintenance A. OPERATIONAL AND MAINTENANCE (O&M) SAVINGS As mechanical and lighting systems age, they require more maintenance, which can strain a facility's physical and capital resources. The proposed project will significantly reduce maintenance by replacing old, maintenance intensive mechanical, plumbing, and lighting equipment. Maintenance cost savings associated with individual energy conservation measures are documented in this section. The projects included in this report involve new equipment with a full service life ahead of them at the beginning of the program. As such, future expenditures for certain equipment replacements are avoided or greatly reduced. Future funds that would be used for replacement of equipment covered in this program can be diverted to other facility needs. These avoided replacement costs are not included in the financial aspects of the program. However, specific reductions in replacement parts are included in the financial aspects of the project and are quantified in this section. Some median estimates of service life are provided by ASHRAE for some of the types of equipment covered in this program. Hot Water Boilers Pumps (base mounted) Air-cooled Condensers Rooftop Air Conditioners Gas-Fired Furnaces Hot Water Unit Heaters 24 - 30 years 20 years 20 years 15 years 18 years 20 years ECMs LI-L6: Lighting ECMs The maintenance savings related to lighting retrofits includes the benefits of replacing existing lamps that have part of their expected life used with new lamps having a full life expectancy, and of the use of new lamps and ballasts with longer lives than existing lamps. The replacement costs for the retrofit assumes that lamps will have to be replaced every five years and that the ballasts will last for twenty years. The tables on the following pages provide the basis for determination of the lighting maintenance savings. Table 4-1 provides the existing maintenance costs, while Table 4-2 provides the expected maintenance costs after the lighting retrofit has been completed. Table 4-3 shows the savings over a term of20 years. No lighting maintenance costs are shown during the first three years after the retrofit as all of the components will be new and will be under warranty. The annual average lighting maintenance savings of $4,413 is prorated by building and presented in Section 2 - Energy Conservation Measures, Table 2-2. Chevron ~ 4-1 Energy Solutions . . .

Section 4 Operation & Maintenance CIP 1: Replace Unit Beater with Infrared Radiant Beat (not in recommended program) With the installation on the direct-fired infrared heaters, the existing boilers will be decommissioned and no longer need to be maintained. Chevron ES was furnished an estimate of $600/year that the City of Salina will save in a reduction of ongoing maintenance costs associated with the boiler at Fire Station No.1. CIP 2: Replace Boiler at Fire Station No.2 (not in recommended program) The replacement ofthe 50 year old boiler at Fire Station No.2 with a modern high efficiency boiler will lead to a reduction in maintenance costs associated with the aging boiler. Chevron ES was furnished an estimate of $800/year that the City of Salina spends annually on maintenance parts and costs associated with the existing boiler at Fire Station No.2. It is assumed that maintenance costs on the new boiler will be half this amount. CIP 2: Replace Boiler at the Police Department (not in recommended program) The replacement of the aging boiler at the Police Department with a modern high efficiency boiler will lead to a reduction in maintenance costs associated with the boiler. Chevron ES was furnished an estimate of $3,200/year that the City of Salina spends annually on maintenance parts and costs associated with the aging boiler at the Police Department. With an allowance for annual maintenance costs of the new high efficiency boiler, an annual O&M savings of $2,700 is estimated to be realized with the boiler replacement. CIP 5: BV AC Improvements / Controls Upgrade The upgrade of the 40 year old HV AC system including air handling units and controls will lead to a reduction in the annual maintenance, parts, and subcontracted repair expenditures by the City for maintaining the air handling units, dampers, ductwork, and fans. Chevron ES was furnished an estimate of $4,000/year for the amount of these annual expenditures. With a small allowance for annual costs to keep the new system in optimal operating condition, an annual O&M savings of$3,500 is estimated to be realized with the HV AC replacement. This annual O&M savings is used in the financial analysis until the year of capital cost avoidance with equipment replacement. CIP 6: Remove Skylight Removal of the skylight at the Health Department building will not only provide energy savings in conditioning the space, but also provide a reduction in annual maintenance costs associated with the skylight. Chevron ES was provided an estimate of $200 that the City spends annually to caulk and seal the skylight to prevent leakage. The City also spends $1,650 every three years to replace the skylight screen installed to reduce the radiation into the lobby space. Overall, the removal of the skylight and replacement with conventional roofing and an insulated ceiling will lead to an O&M savings of$750/year. Chevron ~ 4-4 Energy Solutions . . . Section 4 Operation & Maintenance ECM Cl: Networked Programmable Thermostats Chevron ES was provided an estimate of $300/year for maintenance and replacement of thermostats affected by this ECM. This O&M savings was distributed over the buildings affected by this ECM roughly by the number of thermostats at each building. At Fire Station No. 1, Fire Station No.2, and the Golf Clubhouse an annual O&M savings of$45 is used. At the Health Department building and the Salina Community Theatre an O&M savings of $80/year is used. Section 2 - Energy Conservation Measures describes that for ECM C1, these annual maintenance savings will be more than offset with the $30 web server maintenance fee and with the approximate $40/month ISP service required at the two fire stations and the Golf Clubhouse. ECM Wl-W5: Domestic Water Retrofits O&M savings assume reduced parts and maintenance costs will result after new plumbing systems have been installed. Replacing/retrofitting existing toilet and urinal flush valves with new flush valves as described in Section 2 - Energy Conservation Measures, will not only reduce the water usage per flush but will also result in maintenance savings from fewer repairs to existing flush valves. The annual baseline assumption is that on average, 20% of the flush valves, tank toilets, and sink aerators will need to be rebuilt / replaced each year. Using a cost differential of $20 for each flush valve and tank toilet and $0.50 for each sink, an annual avoided maintenance cost is obtained: (29 tank toilets + 172 flush valves) x 0.20 x $20.00 + 144 sinks x 0.20 x $0.50 = $819 This is based on the assumption that parts have, on average, a five-year life. Chevron ~ Energy Solutions 4-5 . . . Section 4 Operation & Mai.ntenance B. CAPITAL COST AVOIDANCE Much of the major equipment proposed in the ECMs and CIPs replaces existing equipment that is near or beyond its useful live. This existing equipment will need to be replaced within the term of the financing period if the measures are not implemented. Implementation of these projects now will save the City the expense of replacing equipment over the coming years when the end oftheir useful lives is reached. To conservatively estimate the replacement year ofthe major pieces of equipment, the ASHRAE median service life plus 35% was used. Ifthe replacement year has already past, indicating that the equipment is beyond its typical useful life, 2009 was used as the replacement year. Generally, the current subcontracted cost estimate was escalated at 2.5% per year, for inflation, to arrive at the cost of replacement at the end of the equipment's life. These estimates include equipment, supplies, labor, bonds, and contractor overhead and profit. An exception to this is the cost of the split-system replacements at the Health Department building.

CIP 1: Replace Unit Heater with Infrared Radiant Heat (not in recommended program) The capital cost avoidance amount associated with this CIP is based on the direct subcontracted replacement cost of the hot water boiler at Fire Station No. I if it were to remain using the hot water unit heaters in lieu of changing to direct-fired infrared heaters. CIP 2: Replace Boiler (not in recommended program) The capital cost avoidance amount associated with this CIP is based the direct subl.::ontracted replacement costs of the 52 year old boiler at Fire Station No.2 and the 33 year old boiler at the Police Department building with high efficiency hot water boilers as described for CIP 2 in Section 2 - Energy Conservation Measures. CIP 3: Replace Condensing Unit(s) (not in recommended program) The capital cost avoidance amount associated with this CIP is based the direct subcontracted replacement costs of the 15 ton south condensing unit at the Golf Clubhouse, and the six (6) north roof-mounted condensing units at the Health Department building as described for CIP 3 in Section 2 - Energy Conservation Measures. . CIP 4: Replace Split System Units The capital cost avoidance amount for replacement ofthe split-systems at the Health Department building savings is based on the budgeted amount that the City had allocated in 2008 for replacement of two of the five units. The City planned to replace two split systems in 2008 for $29,000. Even though the other three south units are ofthe same age, the analysis assumes that they will be replaced in two years at the same current cost per unit increased for inflation: ($29,000/2) x 3 units = $43,500 [2008 cost] $43,500 x (1 + 2.5% inflationlyr) (2 years) = $45,702 [2010 cost] CIP 5: HV AC Improvements / Controls Upgrade The capital cost avoidance amount used for replacement of the HV AC systems and controls at the Police Department is based on the direct subcontracted replacement costs of the project, as described in Section 2 - Energy Conservation Measures, less the electrical upgrade amount in the CIP pricing. .

Section 6 Measurement & Verification The heart of any performance contract is the guarantees with which it is associated. Not only the guaranteed price of the installation but the guaranteed savings generated from the installation of the energy conservation measures. While the installation guarantee is easy to track and verify, the savings guarantee is more complex, can be done in different ways, and can be left open to interpretation. However, when done correctly, not only can the savings be measured and verified, but the customer can achieve many additional benefits from the equipment installed, over and above the guaranteed savings. The following section introduces Chevron Energy Solutions' Energy Management Group, and outlines some of the services it can provide. Specifically, these topics will address: · Energy Management Group Overview - Including its staff, experience, and capabilities. · Measurement and Verification (M& V) of Savings - What are the options, when should they be applied, and what are the benefits of each. · Client Specific Recommendation - Based on the parameters of this analysis, these are our recommendations for a workable M&V plan that gives the greatest ongoing benefit, and ongoing Monitoring Services. These are included in the base Monitoring fee. · Monitoring Services - The scope of Standard Services included and Optional Extended Services from the Energy Management Group. Measurement & Verification of Savin2:s One key to successfully achieving the predicted savings of any project is the accuracy of measurement techniques employed, and the validity of the energy baselines. To assure confidence in these processes, Chevron Energy Solutions will follow the International Performance Measurement and Verification Protocol (IPMVP). This protocol is recognized by the National Association of Energy Service Companies (NAESCO) as the standard guideline of how savings resulting from energy conservation projects should be measured. The IPMVP defines four broad options for measurement and verification of energy savings. Each option is applicable to specific situations; and, oftentimes, more than one option is possible. Multiple options are often implemented on a single project. The broad categories of the IPMVP layout as follows: · Option A - Partially Measured Retrofit Isolation - End-use measurements, some stipulations. · Option B - Retrofit Isolation - Complete end-use measurements. · Option C - Whole Building - Energy use analysis on multiple systems. · Option D - Calibrated Simulation - Computer modeled building savings. Chevron ~ Energy Solutions 6-1 . . . Section 6 Measurement & Vt~rification Often overlooked is the necessity of identifying the M&V plan coincidently with the project development. In some cases, it is necessary to drop or ignore a portion of savings associated with a specific retrofit for the simple reason that that portion is unreasonably expensive to measure. Implementation of a verification plan for the diverse types ofECM's typically involved in a performance contract usually requires a combination of methods to successfully measure savings. Even for a given ECM, verification categories may be crossed by combining a stipulated and an end-use measurement component into the savings calculation. Factors that guide the selection of an M& V method for each ECM include: * Cost of measurement vs. savings * Timing of measure installation * Likelihood of future ECM's at the same facility * Likelihood of future construction at the facility * Degree of sub-metering within the facility * Complexity ofECM's to be installed * Level of interaction between ECM's * Dynamics of the facility's energy baselines * Likelihood of sustainable savings from the measures Due to the variables and dynamics that are unique to each performance contract, and often to each facility within a performance contract, an individual measurement and verification plan must be developed for each situation. While the specifics may vary, the general method employed will always follow one of the methods outlined in the IPMVP. The following paragraphs detail the M&V methods being recommended for the City of Salina: Option A - Partially Measured Retrofit Isolation This option allows for the energy savings to be calculated using a sampling of field measurements combined with stipulated parameters. The savings, once calculated, are usually stipulated to for the life of the project. Ongoing actual measurements mayor may not be used in this verification technique depending on whether the predicted savings and/or volatility of the measures implemented warrant the expenditure on additional field measurements. A possible application for using this option would be for lighting efficiency improvements whose performance may be relatively stable and not interdependent with other measures. The savings for the lighting upgrade would be quantified by measuring before and after power consumption for a representative sample oflighting circuits and by stipulating or agreeing to the hours of operation of each circuit. Entirely Stipulated Savings While not directly defined as an IPMVP option, the protocol recognizes that there are instances when measurement and verification of the savings is not warranted. In cases where the cost of measurement is too high as compared to the savings, where the parameters preclud1e accurate measurements, or where the confidence of the savings projections is high, the Client and Chevron ~ Energy Solutions 6-2 Section 6 Measurement & Verification . Chevron Energy Solutions may agree to stipulate to those projected savings for the term of the project without any additional measurement and verification of the savings.

Section 7 Environmental Impact Purpose The City of Salina has retained Chevron ES to identify and evaluate energy conservation measures (ECMs) that could be implemented through a performance contract to produce improvements in energy utilization. Chevron ES has conducted thorough surveys of the heating, ventilation and air conditioning (HV AC) systems, lighting systems, building energy controls, water-use areas, and building envelopes of buildings at the City of Salina. The purpose of the survey was to locate and analyze mechanical, controls, lighting, water systems, and equipment to determine which ECMs could be implemented to provide the maximum reduction of energy usage at the minimum cost for the City of Salina. The recommended ECMs in this project address and achieve these goals. Greening Measures for the City of Salina The ECMs that were discussed in Section 2 will reduce the amount of energy used to heat and cool the buildings while simultaneously increasing occupant comfort: . HV AC Improvements and Controls . Replace Split - System Units . Replace Condensing Units . Replace Boilers . Replace Unit heaters with Inferred Radiant Heat However, there are additional benefits beyond energy savings that will be realized through the implementation of many the ECMs: Lighting and PCB Ballast Disposal: All PCB-contaminated materials will be incinerated pursuant to the U.S. Environmental Protection Agency Final Rules 40 CFR 761.70. All uncontaminated (less than 50 ppm PCB's) metal components of the ballast shall be recycled, recovered, or reclaimed. Chevron ES will insure that the ballast disposal company provides a manifest and certificate of destruction pursuant to 40 CFR Subpart K. Environmental Impact on Pollution Direct Emission Reductions: Every mcf of natural gas that is burned by the City of Salina to generate heat will produce NOx, SOx, and CO2 emissions. Reducing the amount of natural gas required to meet the building heating load results in a direct reduction in emissions. The existing annual emissions of NO x, SOx, and CO2 compared to the projected annual emissions for the Recommended Program presented in Section 1 is shown in Figures 7-1 through 7-3 below. These results are determined from the energy savings that would be generated by the proposed ECMs that reduce natural gas consumption. Chevron U Energy Solutions 7-1 . . .

Section 7 Environmental Impact Indirect Emission Reduction Indirect emissions are defined as the emissions associated with generating electricity at the utility's power plant, which is assumed to utilize fossil fuels to generate steam. Chevron ES has identified ECMs that would result in reduced electrical consumption, and if implemented, these ECMs would aid in the reduction of emissions such as NOx, S02, and C02 produced during electrical generation. Every annual 1 0,000 kWh reduction in electricity use equates to the carbon sequestering of 2.5 acres of pine or fir forest or equivalent to taking 2 average cars off the road each year. fit tit ~ The corresponding environmental impacts of implementing the Recommended Program presented in Section 1 is shown in Table 7-1 below, and is based on the projected electrical energy savmgs.

(NYSE:WR) today fIled with the Kansas Corporation Commission (KCC) a request to increase its rates to recover the cost of providing electric service to its customers. Westar is seeking an increase in rates of about 15 percent for both its north and south regions. The increase in the northern region is $90.0 million and in the southern region it is $87.6 million. The combined increase is $177.6 million, and for each region reflects an increase of just under 15 percent. The average residential customer would see a per month increase of $9.62 in Westar's northern region and $10.34 in Westar's southern region, based on usage of 900 kilowatt-hours (kWh) of electricity. The national average retail rate is 9.2 cents per kWh. With the requested rate increase, Westar said its average rates will be 6.9 cents per kWh. "On a combined basis, our average rates today are lower than they were 20 years ago," said Bill Moore, Westar's president and chief executive officer. ''This is even more dramatic in our southern area, where our average rates are significantly lower than they were in 1988- something in stark contrast to other energy costs." - MORE- Page 1 of4 . . .
