Executive Summary
Intro4uction
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
of these 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 oflittle 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:

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 improv~ent 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

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.

Financials
The financial aspects of the project are presented in the following Table 1-2. Working in
conjunction with the Rod Franz, the City Finance Director, a net present value of comparative
scenarios is presented. A 3.0% annual inflation rate was used for electric and natural gas energy
savings, a 9.0% inflation rate was used for water and sewer savings as determined from the future
rates that have already been established, and 2.5% annual inflation rate was used to project
materials savings. Materials savings only were shown for all operations and maintenance
savings. No in-house City labor costs are included in the materials savings, although a reduction
in labor expended will be recognized with the implementation of these ECMs. All projects in
this report are comprehensive including engineering, construction, installation labor, and
materials. The total implementation costs were determined in accordance with paragraph 5.1 of
the Investment Grade Audit Agreement. A breakdown ofthese costs into the State Master
Agreement categories follows in Table 1-3.

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 TIluminating 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.

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 of the 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.
