APS Energy Services will be partnering with Carollo Engineers, a leading expert in the planning, design and construction management of water and wastewater projects for public agencies, municipalities, private developers and industrial and agribusiness companies. Their areas of expertise include: Water, Wastewater, Energy, Air Quality, Stornnwater, Water Reuse and Groundwater.
Carollo Engineers proposes Mark Gross as its Project Manager for the evaluation of water and wastewater facilities in support of APS Energy Services' performance contract with the City of Tempe. Mark is very familiar with the City of Tempe's business practices, utility staff and facilities. More importantly, he is a design engineer with more than 18 years of experience who is able to recognize opportunities for energy and cost savings through modified operations and equipment improvements. Mark will be supported by Guy Carpenter, who also has 18 years of experience, eight of which was working for a municipal utility in a role that included responsibility for water and wastewater facility maintenance and operational efficiency. Guy recently conducted an energy efficiency audit and energy "road map" for a utility in Arizona and will work with Mark and Carollo's process and electrical engineers to develop potential Energy Conservation Measures (ECMs) through operational changes and equipment modifications, as appropriate. The commitment of Carollo's resources for the success of this project will be reinforced by the presence and involvement of Bob Ardizzone, the Managing Partner of Carollo's Phoenix office. Mr. Ardizzone has intimate familiarity with the South Tempe Water Treatment Plant, as he has been the project manager for two design projects and the production of an interactive Operations & Maintenance Manual for the facility.

They currently maintain 28 offices in North America, through which they have successfully completed more than 20,000 projects for public sector Clients. Carollo is currently ranked within Engineering News Record's (ENR) top 100 design firms. More importantly, ENR's annual Source Book ranks Carollo among the top firms for water and wastewater treatment plant design. Unlike their competitors, Carollo only provides water and wastewater engineering services. They recruit

nationwide and hire technical staff that have extensive background and training specific to this
field. For that reason, the quality and professional standing of their core group of water and
wastewater professionals equals or exceeds that provided by some of the largest engineering
firms in North America. They have recently completed or are performing ongoing water and
wastewater projects for many of the country's major municipalities or special districts.
Carollo has nearly 700 employees on staff including approximately 350 registered engineers.
They are a full-service company with the experience and qualified professionals to successfully
manage projects of any size. Their staff includes civil, sanitary, environmental, electrical,
mechanical, chemical, structural, control system and corrosion control engineers, as well as,
architects, planners and specialists in other areas. Their services cover all phases of municipal
water and wastewater projects, from studies and master plans, through facility and financial
planning, design, construction management and operations support. Carollo works with Clients
to develop optimal water, wastewater and infrastructure systems and facilities. By integrating
their Client's community values and goals with their knowledge of water resources, science-
based research, cutting edge technology, and their business-based decision and stakeholder
consensus building techniques, they provide Clients with comprehensive services that integrate
sustainability into their projects.
Through their experience with water and wastewater infrastructure design and the associated
relationships they develop with operators, engineers, and utility managers, they know that the
most important thing to Clients is the protection of public health and the environment through
compliance with applicable regulations and rules. They also know that this is followed in
importance by the service level a utility must provide to continually satisfy its customers. With
these priorities firmly in mind, Carollo will evaluate the City of Tempe South Water Treatment
Plant (and potentially other water and wastewater facilities) to provide recommended Energy
Conservation Measures (ECMs) that do not require a sacrifice in regulatory compliance or service
levels. This may seem an obvious responsibility, but energy efficiency evaluators who are not
well-versed in the operational requirements of water and wastewater facilities have a greater
potential to develop ECMs that are not implementable and therefore essentially meaningless.

plants and wells. Please see the Appendix for more details on Carollo Engineers.

11. Describe the nature of work generally conducted by subcontractors.
APS Energy Services will maintain onsite full-time Construction Manager(s) throughout the entire
duration of the project. An important part of APS Energy Services' approach to providing solid project management and high-quality customer service is to establish a strong local presence for
every project. We manage subcontractors at the first tier level, avoiding unnecessary middlemen
and mark-ups. Typically, APS Energy Services hires only labor subcontractors preferring to utilize
buying power for equipment to achieve additional savings on behalf of our Clients. We anticipate
using labor subcontractors from the following trades: electrical, building control, mechanical,
plumbing, lighting and water conservation.
We will ask your team for the name of two or three contractors who have performed well for you
in the past for each of the trades. We will help the City of Tempe standardize installed equipment, helping to lower the cost to maintain your facilities. Additionally, APS Energy Services
will prepare specifications, scope and drawings to obtain subcontract work and materials for the
City.
APS Energy Services strongly believes in keeping its business in the communities where the
company is invited to work by using local companies as subcontractors as often as possible.
APS Energy Services will assume full responsibility for all project work and services performed by
our subcontractors. Our subcontractor team will adhere to all provisions and conditions in this
RFR.

13. Indicate the number of energy savings audits you have performed for water treatment facilities and wells for the past 5 years and the savings that were generated.
Carollo Engineers has been involved in more than 20 projects in the past 5 years that have either
been specific to energy savings audits, or had an energy savings work element associated with
the project (such as for a facility master plan or optimization study). These projects have been
for water and wastewater facilities.
For the Olathe (Kansas) WTP 2 Expansion Project, which included a modified treatment train and
operations of Finished Water Pump Station, annual savings in chemical costs were $100,000, and
annual savings in energy costs were also $100,000.
For the City of Escondido (California), Carollo testing and modification of the dose control
algorithm has allowed a 4 mgd system to be expanded to 8 mgd without adding a single UV lamp.
This can be viewed as increased capacity, or as a 50% reduction in energy use per gallon of
treated water. Under current operations, the testing saves Escondido $50,000 per year in energy.
14. Is your firm accredited by NAESCO (National Association of Energy Service Companies)?
APS Energy Services is focused on the five southwestern US states. The expense of national
certification is not necessary given our goal of being a high quality, boutique Energy Services
Company focused on custom solutions for our select Clients. As such, APS Energy Services is not
an active member of NAESCO; however, APS Energy Services is on the Department of Energy's
Qualified List of Energy Service Companies.
15. Describe your general approach to auditing a facility for all levels of audits requested. Include, at a minimum: what is involved, how is customer involved, methodical approach, etc.
APS Energy Services views the audit process as a partnership between APS Energy Services and
the City of Tempe. Prior to the start of the audit process, APS Energy Services' personnel will
meet with the City of Tempe to determine the financial and technical goals, needs and
constraints. A plan is then developed for the Audit and implementation process to provide
effective solutions and strategies that meet the City of Tempe's goals and needs within the City's
schedule constraints. Following the development, the plan is discussed to ensure thatit meets all
of the City's expectations. Each project has assigned dedicated team that is involved in the project from the start. The team includes a sales representative, audit lead, project engineers,
energy auditors, contract specialist, construction project manager and administrative support.
Team members will be involved in different capacities in all aspects of the project from the start
of the Audit until the conclusion of construction. These team members, under the guidance of an
on-site Project Manager, will from time to time require the assistance of City Facilities personnel.
Listed below is the time-proven methodology APS Energy Services uses to develop baseline
operating costs and savings projections, as well as, measurement and verification methodology
to ensure program success. In an initial site survey or a preliminary audit, APS Energy Services
performs the following steps for each facility:
• Performs a utility analysis of the facility, using past energy and water history, to determine
the monthly energy, water and gas consumption and demand profiles, and to compare the

energy use indices of the facility with similar facilities in the same geographic location. This
step will provide important preliminary information about the existing potential at the facility
and typically takes one to two days to accomplish, depending on the facility size and the
availability of the information.
• Review of available facility's blue prints and specifications to become familiar with the facility
systems and equipment. This step typically takes two to four days to accomplish depending
on the facility size and the availability of the information.
• Interview operating personnel and occupants to gain a better understanding of the building
systems and operations, and to discuss any issues or problems that must be addressed as part of the overall solutions that the audit presents. This step typically takes one to two days
to accomplish.
• Perform an initial walk through of the facility to become familiar with the building systems and equipment and compare the actual systems with the original design. The result of this
walk through is to develop a list of potential energy and water conservation measures and
engineering solutions to problems that were identified by the facility operators. This step
typically takes three to six days to accomplish depending on the facility size and the
availability of the information.
• Perform preliminary analysis of the feasibility of the potential measures. This step typically
takes three to six days to accomplish depending on the facility size and the availability of the
information.
• Prepare a preliminary report that includes financial and technical solutions that meet the
City's goals and objectives. Present the findings to the City for feedback and approval. This
step typically takes three to five days.
Upon completion of initial site survey, APS Energy Services would then initiate the following steps
in an Investment Grade Assessment for each facility included as part of the assessment:
• Complete a detailed field survey of the facility, which includes inspecting the building
equipment, operation, performance and issues. This step can involve short term or spot
monitoring of a statistically significant sample of equipment; collecting detailed data such as
counts of lighting fixtures and name plate data on equipment; and operational logs to
establish an accurate energy consumption baseline for the facility. This step typically takes
two to three weeks depending on the size of the facility and the complexity of the systems.
Please see Question # 7 for a list of systems that APS Energy Services surveys during the
audit.
• Perform detailed energy analysis for the facility using established engineering methodologies
and tools. The analysis starts by using the field collected data to establish an energy and
demand baseline for the facility. The calculated baseline is then compared to existing data,
such as billing history, for accuracy. The baseline is also used to develop end use breakdown for the facility to indicate the consumption of the individual systems to the total energy use
and demand. The proposed energy conservation measures are then analyzed using
established engineering software (e.g. DOE2.1E, VisualDOE, TRACE 700) or engineering
models (i.e. spreadsheets) to establish the potential savings of these measures. This step
typically takes five to seven weeks depending on the size of the facility and the complexity of
the systems.

O Operational and maintenance (O&M) savings are determined much differently than energy savings. O&M savings require the complete support and buy-in of the facility management staff. APS Energy Services will guide the City's facility management staff to help find true O&M savings. However, the City must make the final determination regarding the inclusion of each operational savings component. The O&M savings are typically taken because of the reduction in the required maintenance for new equipment, and are not intended to reduce maintenance staff. This step typically takes three to five days depending on the size of the facility and the complexity of the systems.
O A conceptual design for the recommended measures will be developed. The design will include equipment selection, systems modifications and verification that all recommended measures meet all applicable codes and standards. This step typically takes one to two weeks depending on the size of the facility and the complexity of the systems.
• Implementation schedule and cost estimates for each measure is developed to verify the feasibility of the proposed measures. Measures that do not meet the City's financial and technical objectives are removed from the project. This step typically takes one to two weeks depending on the size of the facility and the complexity of the systems.
• A detailed report discussing the results of the audit is prepared and presented to the City. The report includes the financial and technical solutions and makes the technical and financial case for the implementation of the project. The report will include measures that are economically feasible and a list of those measures that are not economically feasible but considered for the project. This step typically takes one to two weeks depending on the size
of the facility and the complexity of the systems.
16. Describe your firm's approach to the technical design of this project.
Engineering design is a core competency of APS Energy Services. Our staff performs all mechanical, plumbing and electrical design. The mechanical and electrical engineers that will be responsible for the construction documents are licensed Professional Engineers in the State of
Arizona.
Sequence of Engineering Design Services
City of Tempe Selects Energy Conservation Measures (ECMs): After the City has reviewed the
Investment Grade Assessment Report and agreed to the ECMs for inclusion in the energy performance contract, we will prepare a design scope of work, schedule and list of deliverables.
Design Selected Energy Conservation Measures (ECMs): APS Energy Services will first develop a
schedule for the project design services and will submit this to the City for review and approval. APS Energy Services will then move forward with the preparation of AIA construction documents
for the selected ECMs. Construction documents will be prepared for each type of construction (i.e. lighting retrofits, energy management systems, HVAC retrofits, water conservation retrofits, etc.) This will allow us to bid projects separately to specific groups of City approved subcontractor bidders. We will provide the City with review sets at 75% and 100% completion for comments and concurrence with the design. Construction documents will not be issued to bidders until the City
has approved the documents.

17. Describe standards of comfort and functionality that are generally used for light levels, space temperatures, ventilation rates, etc. in the intended facilities.
Lighting
Light levels will be maintained to Illuminating Engineers Society (IES) recommendations for each
type of space being improved. Light levels will be maintained by City of Tempe staff throughout
the contract by group cleaning and group relamping. In addition, the performance of newer lighting technologies (T-8 lamps and electronic ballasts) does not depreciate over time as fast as
the existing equipment (T-12 lamps and magnetic ballasts).
Space Temperatures & Ventilation Rates
Ventilation rates for the existing facilities will be evaluated to verify that they meet American
Society of Heating, Refrigeration, and Air Conditioning Engineers (ASHRAE) Standard 62.1-2004.
In the event they do not meet the ASHRAE Standards, recommendations will be provided to the
City on how this can be accomplished. Space temperatures and ventilation rates will be
maintained to ASHRAE standards during the design and implementation phases. Space
temperatures and ventilation rates will be maintained throughout the life of the contract by City
of Tempe staff by performing preventative maintenance on air handlers and HVAC equipment
and also by monitoring conditions through the Energy Management Control System.
18. Describe in detail the methodology your firm normally uses to compute baseline of energy and water use as well as performance.
The process for baseline development that APS Energy Services adopts consists of a
comprehensive comparison between theoretical prediction and actual operation as determined
from equipment parameters and utility data. This process is based on established engineering
standards such as International Performance Measurement and Verification Protocol (IPMVP).
The process begins by collecting and reviewing at least two years of utility history for the audited
facilities to establish a base year for the analysis. This review is to ensure against the
misapplication of utility rates or an abnormal year's usage profile and to provide verification for
the analysis results. During the Audit, data is collected on the facility operation and the systems
in the facility. This data includes name plate data, short term monitoring, spot measurements,
and original construction documentation. The field collected data is then used to establish
baseline consumption at different levels. The baseline consumption may be developed for
individual measures or for the facility as a whole, depending on the considered measure and the analysis level that is used to calculate the energy savings. The baseline is established using
working models, such as DOE 2.1E or TRACE 700 or using spreadsheet models for individual
measures. The developed models are used not only to determine the baseline energy and water
consumption but also to evaluate the predicted savings for the recommended water and energy
conservation measures. The baseline that is established with the model is calibrated against the
base year that was established from the utility bill analysis. APS Energy Services will develop a
high degree of confidence in the baseline both internally and with the City before proceeding
with the analysis.

19. Describe the method(s) used to adjust the energy, water and O&M baseline due to such factors as weather and facility use changes. Describe factors that would necessitate adjustment.
APS Energy Services will apply the IPMVP methodology for baseline adjustments. The IPMVP
defines two types of adjustments. The first type is called Routine Adjustments that include
changes in parameters that can be expected to happen throughout the post-retrofit period and
for which a relationship with energy use/demand can be identified. These changes are often cyclical, such as weather or occupancy variations. Routine adjustments are included in the basic
mathematical model and the model can be adjusted to recalculate the effects of these changes
on the energy and water savings. The second type is called Non-Routine Adjustments. These
adjustments include parameters that cannot be predicted and for which significant impact on
energy use/demand is expected. Such parameters include changes in the amount of conditioned
space, changes in the amount or use of equipment, changes in environmental conditions (lighting
levels, set point temperatures, etc.) for the sake of standard compliance, and changes in
schedule, occupancy or throughput.
20. List all procedures, formulas and methodologies including special metering or equipment, which your firm will use to calculate energy, water and O&M savings. Include assumptions made in the calculations.
Water and Energy Sayings
Our approach to the analysis of energy-using systems starts by analyzing the data collected
during the site survey. The analysis will help in evaluating the initial feasibility of the
recommended measures. Then, for those Energy Conservation Measures (ECMs) that require
further energy analysis, the analysis may include developing computer-based temperature bin analyses or building or system simulation models. The decision will be based on the number, size
and type of ECMs being considered.
The Technical Site Analysis will entail a thorough site survey to collect required data, followed by
the potential creation of a computer model of the facility's energy using systems. Input data to
this energy usage model will include an inventory of the major energy using systems, occupancy
and use profiles, hours of operation, and pertinent weather data. Key data input includes metered and/or measured equipment performance characteristics to help establish the baseline
criteria. The computer simulation will be calibrated against established billing history that is
developed from utility analysis. The calibrated model will be used to determine the feasibility of
installing specific ECMs. Evaluation of these ECMs will encompass measure costs, projected
savings, effects on system maintenance costs, secondary impacts on other water and energy
using systems and life cycle costing.
An hourly energy analysis software program, such as Trane Trace 700 or DOE 2.1E, may be used
where several ECMs are proposed within one building with interaction of the impacted systems.
All calculations shall conform to ASHRAE standards. Load impacting ECMs (building envelope,
lighting systems, etc.), system distribution load ECMs (air handling equipment, pumps, etc.) and
generation load ECMs (cooling system heating, etc.), will be developed and analyzed. APS Energy
Services also investigates the feasibility potential of alternative type measures such as solar and
cogeneration.

Savings from lighting and water efficiency measures will be calculated using customized
spreadsheets. For some cases, a new lighting system may be proposed and may require
evaluation of a new layout. In this situation, quantity and type of fixtures and resulting light levels
will be calculated using lighting software. The interactions between the high efficiency lighting
system and the mechanical systems will also be calculated and included in the analysis.
0 & M Savings
APS Energy Services will guide the City facility management staff to help find true O&M savings.
However, the City of Tempe must make the final determination regarding the inclusion of each operational savings component.
Many times operational savings are found by reviewing past purchase orders for repair parts and
outside service contracts. Therefore, APS Energy Services will assist the City in reviewing cost
center records and budgets to locate potential operational cost savings that can be achieved by
replacing equipment under the performance contract, or by taking on maintenance and repair
responsibilities which are currently being performed by outside contractors.
APS Energy Services does not anticipate including City facility management labor reductions as an
operational savings category. It is assumed that the City will not be interested in reducing staff
because there are many other areas where staff can be reassigned if required maintenance tasks
are reduced or eliminated due to new equipment installed by APS Energy Services. Examples of
operational savings include the following: Annual dollars spent on lamps and ballasts, based on
consolidation of equipment types, new warranties, increased equipment life and reduction of
equipment components resulting from the comprehensive lighting retrofit; Average annual cost
the City spends on repair parts for a piece of equipment that will be replaced; Annual service
contract cost if contract can be discontinued due to the performance contract.
21. Describe the procedure to assign dollar values to the savings. Include energy savings as well as maintenance or material savings.
When evaluating current energy prices, the structure of the rate must be examined to determine
the consumption, demand and time-of-use characteristics. Using a simple blended $/kWh rate is
not always the most accurate method for determining the dollar savings associated with energy
conservation measures. For instance, control measures (i.e. energy management system or
occupancy sensors) may not reduce the utility-measured peak demand in a month. If a time-of-
use rate schedule is in effect, it must be included in the evaluation and could necessitate the
development of a building energy simulation model for accurate calculations. All of these factors must be considered when calculating dollar savings.
An estimate of the energy savings and cost savings will be determined using current energy
prices. The simple payback period, in years, a detailed project costing, project life and an
indication of any change in operation and maintenance costs will also be included. A cost analysis
of each project will incorporate these factors. Escalation, discount rate and other parameters
germane to this life-cycle analysis, if required, shall be submitted for approval prior to life-cycle
evaluation.

22. Describe your firm's procedures and schedule for measuring financial performance of projects.
The method for calculating cost savings will vary slightly for each Energy Conservation Measure. The annual savings are guaranteed through a pre-defined measurement and verification protocol. The performance of the individual efficiency projects is measured at the completion of construction to validate the guaranteed savings. In accordance with Arizona State law, the measurement and verification process is repeated at the end of years 1, 4, 7 and 10. Reports will be submitted at these intervals. Any shortfalls in savings identified through this process, are either technically or financially resolved. APS Energy Services will perform a detailed investigation to determine all applicable adjustments to the baseline and energy savings calculations. This detailed investigation will include site visits and inspections to ensure all applicable equipment is in place, audit of all settings on equipment to determine operational changes from calculations of baseline and savings, and monitoring of appropriate services to determine adjustments in operations from stipulated or assumed values used in calculations of the baseline and savings.
A Registered Professional Engineer and Certified Measurement and Verification Professional shall perform all work necessary to determine appropriate savings adjustments and provide a final report outlining actual savings in accordance with the appropriate calculation of baseline and
savings.
23. Describe how the guarantee provisions work in the event that project results vary from projections. Also describe how excess savings can be documented.
In the event that the final M&V Report does not verify the expected energy savings in accordance with the M&V Plan, APS Energy Services shall repair or replace the Energy Conservation Measure that is not performing at the required level, as identified in the M&V Report.
If, after the opportunity to make corrections, the final M&V Report, as amended, indicates that energy savings are still less than expected energy savings for that year, APS Energy Services shall pay the City within thirty (30) days of receipt of the M&V Report, an amount equal to the sum of the present value of the difference between the Expected Energy Savings for each year in the payback period and the energy savings shown in the M&V Report.
24. Describe particular characteristics of how your firm approaches performance contracting.
There are many attributes of APS Energy Services and how we conduct ourselves that
differentiate us from our peers.
One of those attributes is the fact that our local headquarters is in Tempe, AZ on the south side of Tempe Town Lake on the corner of Rio Salado and Mill Ave. Having our office right here in Tempe allows us to have an intimate knowledge of the City of Tempe, its landscape, its challenges, and its successes. It also affords us the opportunity to participate in the local legislative process and to have an intimate knowledge of the local vendor community. Not only does APS Energy Services know the vendors, but we are also vendor and equipment neutral. Put another way, we do not own any proprietary technology or manufacturer of equipment which we might feel obligated to promote or sell as part of our performance contracting project.

As a local member of the community, we take a great deal of pride in the fact that no other energy services company has done the amount of work that we have done in the state of Arizona. APS Energy Services has completed over $250 million in energy performance contracts in this state. APS Energy Services is also proud to claim sixty nine full time employees who are all exclusively energy focused and who all live in this community, including a dedicated Utility Rebate Department and Measurement and Verification Department.
Given the current economic times and the budgetary constraints the City of Tempe currently finds itself, engaging with an energy services company who knows and understand s the financial landscape and how to secure financing is crucial to the successful completion of a project of this type. APS Energy Services does not make money on money, i.e. finance the projects. However, APS Energy Services does enjoy a relationship with a party who has successfully blended many different bond programs to fund a multi-phase project for the City of Reno. APS Energy Services won the competitive process and earned the right to perform the work for the $18 million City of Reno project. But, without the creative and innovative financing the project would still be on the drawing board. APS Energy Services proudly enjoys a relationship with the party who made that financing happen for the City of Reno and looks forward to dedicating his services to this project for the City of Tempe if we are fortunate enough to win this competitive process.
25. Describe the structure of the financing arrangement including: projected interest rate, financing term, repayment schedule, equipment ownership, security interest required, the responsibilities and liabilities of each party, and any special terms and conditions that may be associated with the financing of this project.
Overview of Financing Structure
Securing financing is an integral part of any project. With the financing industry in turmoil, the only known factor is that things change. At the same time, there are a series of incentives for energy projects from the federal government. Some incentives are for public projects, such as tax credit bonds, while some incentives are for privately owned projects such as the 30% grant in lieu of tax credit for renewable energy, available only to taxpaying entities. APS Energy Services understands how important securing the appropriate financing has become and how complicated it can be as well. Lease-purchase is a structure that works very well for energy improvement projects and can be used with the incentive programs that follow.
Each project must be analyzed for available incentives as a public project and also as a private project. Each incentive has its own regulations which may include prevailing wage requirements or a Buy American stipulation. Some public projects may be structured to have a 3 rd party owner and become a privately owned project, if the incentives are compelling. APS Energy Services has the expertise to manage the analyses necessary to make informed decisions in today's financing climate.
Tax Credit Bonds
Tax credit bonds provide a subsidy for qualifying projects through 4 distinct programs. For each program the issuer must be a municipal entity issuing debt that would otherwise qualify to be tax-exempt. The debt issuance is taxable and the purchaser of the debt receives a tax credit designed to be in lieu of interest. On March 18, 2010 a change was signed into law which allows

the issuer to receive an interest rate subsidy equal to either 70% or 100% of the tax credit rate set by the U.S. Treasury. What was a tax credit for investors has become a direct cash subsidy to the issuer. This new option will make these debt issuances more attractive to a wider variety of
investors since the debt will simply be a taxable debt investment.
The goal of this program was to create an interest free loan; however, this goal was very rarely met as the tax credit was not sufficient compensation to the purchaser and the issuer was usually required to pay an additional interest rate (typically 1-3%). The term and tax credit rates are set by formulas tied to current interest rates. The tax credit rates change daily and the term can
change monthly.
Tax credit bonds have been valuable tools for several projects, including a project APS Energy Services is implementing for the City of Reno, Nevada. A Clean Renewable Energy Bond was issued for $2.34 million at 1% interest.
The four distinct types of tax credit bonds are as follows:
• CREBs — Clean Renewable Energy Bonds
o New renewable energy projects, can be used for reimbursement
o Allocation has an application process
• QECBs — Qualified Energy Conservation Bonds
o Renewable energy and energy efficiency
o Allocation by formula
• QSCBs — Qualified School Construction Bonds
o Any capital project or land acquisition
o Allocation by State
• QZABs — Qualified Zone Academy Bonds
o May include energy projects; still requires 10% contribution
o Allocation by State
The last two, QSCBs and QZABs are only for K-12 schools. CREBs have an application process which has not been set for 2010. For QECBs the State has released their allocations by formula which can be seen here: http://www.azcommerce.com/doclib/financehecballocation.pdf . The
City of Tempe has received an allocation of $1,852,098 in QECB.
CREBs can be used for new, renewable energy projects. QECBs can be used for a series of qualified uses that include energy retrofits of buildings that achieve over 20% efficiency, green community programs, renewable energy projects and more. All 4 of the tax credit bonds require compliance with federal prevailing wage laws. QECBs and CREBs receive an incentive of 70% of the tax credit rate set by the U.S. Treasury. The tax credit rate for all 4 programs as of March 26, 2010 was 5.90% and the maximum term, which can change monthly, was 16 years.

Build America Bonds and Recovery Zone Bonds
Build America Bonds provide a 35% subsidy on the interest paid on a taxable bond issue for projects that would otherwise qualify for tax exempt financing. There is no allocation process. If the project qualifies, it can simply be designated as a Build America Bond. Typically, both tax exempt and taxable rates are sought from underwriters so the issuer can compare both to insure that the most cost effective rate is chosen. Additionally, taxable interest rates have been less than 35% higher than tax exempt rates making Build America Bonds an attractive program. Prevailing wage requirements do exist and legal opinions can differ depending on the size and nature of the selected option. The method of issuance can be determined by the issuance (i.e. revenue bond, installment purchase, etc.)
The State of Arizona has received allocations in a federal bond program called Recovery Zone Bonds. These are very similar to Build America Bonds but they provide a more generous subsidy for municipal projects and the ability to issue them is allocated by the federal government. This program has two different categories: bonds for uses that would otherwise qualify for tax-exempt financing or Economic Development Bonds; and bonds that are for private activity or Facility Bonds.
Cities and counties ("Issuer") within the State have received direct allocations based on a formula created by the federal government. The formula is based on economic factors and is designed to provide targeted assistance. The debt must be issued before January 1, 2011 (unless an extension occurs). The term is not limited like tax credit bonds (CREBs, QECBs, etc.).
Economic Development Bonds are issued as taxable debt for municipal projects that would, in all other ways, qualify for tax exempt status. The U.S. Treasury provides the Issuer a 45% rebate on the interest rate paid by the Issuer. The rebate is paid in conjunction with scheduled debt service payments and the method of debt issuance can be of the Issuer's choosing (i.e. general obligation, revenue, or lease-purchase). The taxable market has attracted international investment, investment from pension funds and other taxable investors which have made the resultant interest rate for other Recovery Zone Economic Development Bonds quite attractive. These bonds require compliance with federal prevailing wage laws.
Facility Bonds simply pass on an interest rate that is tax-exempt to private activity projects that would otherwise be required to issue debt on a taxable basis. An Issuer would be required to issue the debt, which would not necessarily result in an obligation for repayment to the Issuer. There is no indication that Facility Bonds require compliance with prevailing wage laws.
If an Issuer chooses to utilize this program for energy improvements, the Economic Development Bonds could be used to finance the cost of the energy efficiency work on municipal buildings and the Facility Bonds could be used to finance a power purchase agreement for any solar projects in which the Issuer may wish to engage. In both instances, energy savings could be contracted to be sufficient to repay the debt service.
The Issuer would also be required to define the recovery zone. Other municipalities have done this by simply designating the entire city as a recovery zone through a resolution.

26. Describe the mechanics of the financing arrangement, including equipment ownership, responsibilities/liabilities of each party, security interest required and any special terms and conditions that may be associated with the financing this project.
Third Party Ownership
Many solar projects throughout the country have utilized 3 rd party ownership in the form of
Power Purchase Agreements (PPAs). A Special Purpose Entity ("SPE") is created to own and be a conduit for benefits. This can be a very powerful tool as it can allow a private party to realize the 30% Investment Tax Credit and accelerated depreciation on a project that provides power to a tax exempt entity that would normally not be able to utilize a tax credit. Currently the Investment Tax Credit can be realized in the form of a grant, making the incentive is much more
attractive.
Some common details of third party PPAs are as follows:
O The projects are net metered by the local utility
• The State regulates the PPA process
• Federal tax credits are available since the owner/PPA provider is a for-profit company
O The utility incentives can be realized and are to purchase the Renewable Energy Certificates (RECs), therefore an analysis of the value of the RECs in relation to the incentive is crucial
• The risk is borne by the owner/PPA provider, however, these PPA contracts can be written to deliver power as generated and not guarantee any level of generation
• The PPA provider is typically responsible for financing the project
O For assuming the risk and attaining the financing, the PPA provider realizes the benefits and passes them through to other participants as contracted by the terms of the power purchase
agreement
O The tax benefits may be utilized by the PPA provider or sold to tax equity investors
APS Energy Services is currently exploring the concept of utilizing the PPA structure to include energy efficiency in this type of financing which has been used primarily for renewable energy. Based on legal review and underwriter interest, we believe that we may be able to provide a very powerful solution that would take the task of financing away from a municipal Client completely.

27. Please comment on how you would work with the City to utilize tax-exempt financing if appropriate, or other methods to keep financing costs to a minimum.
With tax revenues down across the State and across the nation, simply asking the City to issue a
tax-exempt bond or capital lease using general fund balances, revenue streams, or the security of
a general obligation is the last option to be considered. The incentives outlined in the previous
sections for energy projects will be considered first. At the same time, the benefit of the incentives will need to exceed the benefit provided by tax-exempt financing.
If tax exempt financing is determined to be necessary, the structure would most likely be lease-
purchase as this structure does not require the commitment of a revenue stream or general
obligation commitment and can utilize relatively standardized legal documentation.
APS Energy Services has contracted the services of a financial consultant with experience as an
underwriter and financial advisor. The consultant has the ability to act as the financial advisor on
debt issuance as tax exempt lease-purchase or any one of the incentivized programs listed above.
This could save the City the cost of paying for the services of a separate financial advisor. Please
contact APS Energy Services for more information about this additional service.
28. Describe any utility rebates or other incentives that you can potentially provide and/or facilitate.
In a typical year, APS Energy Services will secure for our Clients in excess of $5 Million in utility

keep abreast of the latest incentive program guidelines to help maximize the amount of
additional funding our Clients can expect to receive. We will research all options for the City of
Tempe to provide the maximum amount of rebates the City may qualify for.
In addition to the energy and operational savings that will occur through the implementation of a
program of this type, there are three additional sources of funding which APS Energy Services will
explore on behalf of the City of Tempe. They are as follows:
• Arizona Public Service (APS) Energy Study Incentives — Arizona Public Service (APS)
offers up to $10,000 to its business account customers to help fund energy audits. APS
Energy Services will complete the energy study incentive application on behalf of the City.
The City will review and sign the completed application which is then submitted to APS.
When approved, the incentive check goes directly to the City.
• Arizona Public Service (APS) Retrofit Incentives — Arizona Public Service (APS) offers
both prescriptive and custom incentive programs for the installation of qualifying energy
saving measures. It is important that the rules regarding these applications be followed
exactly. APS Energy Services has an excellent track record in securing these incentives and has a dedicated team that will complete the retrofit incentive applications. The City will then
review and sign the completed applications which are then submitted to APS for approval.
Once the retrofits are installed and the pre- and post inspections are completed, the
incentive checks go directly to the City. Based on our initial assessment of the City, APS
Energy Services estimates these incentives will exceed $1,565,666.

• Federal Funding Opportunities — Various Federal programs such as Energy Efficiency
Conservation Block Grants (EECBG), American Reinvestment & Recovery Act (ARRA) and
Economic Recovery Bonds will be evaluated by APS Energy Services on behalf of the City.
29. Do you agree to open book pricing for your firm and any utilized sub contractor?
Yes, APS Energy Services agrees to and is willing to utilize open book pricing for our firm and any
of our sub contractors.
30. Describe your firm's capabilities in providing technical training for City personnel.
Initiating an energy performance contract begins a continual improvement process, rather than a
specific project that has a short term goal. Trained staff can make a difference between energy
performance contracting projects that exceed savings targets and those that require continuous
program resolution and extra staffing. To ensure the performance contracting process is
successful, the City of Tempe facilities staff and APS Energy Services' Team will work together as
partners with the common objective of protecting the performance contract investment while
optimizing savings. To this end, training will play a critical role in arming the individual City facility
operations staff with an understanding of every aspect of the program. This will help to maximize
savings through efficient operation of each Energy Conservation Measure. Likewise, we have
found that encouraging a sense of ownership by the City staff during the training can act as an
efficiency multiplier. This ownership will come from involving them in the diagnosis, design and
installation of improvements from the beginning.
APS Energy Services has developed the following four-step training approach:
1. Onsite classroom training in particular technologies using displays, practice modules and
O&M manuals prepared by manufacturers and from practical experience.
2. On-the-job nnentoring involving appropriate City personnel in obtaining ideas for efficiency improvements, considering the design issues involved, drawing the list of suppliers/
contractors for bids, reviewing the bids, supervising installation and commissioning the new
equipment by testing under load. The APS Energy Services Project Manager will form a
project team at the start that includes those who will have significant roles in operating, maintaining, and repairing the new equipment. As we learn the details of the actual facility,
who the key users are, and how they work, we will be better able to schedule project work
around critical occupants/staff needs.
3. Offsite training, usually provided by the manufacturers under APS Energy Services
supervision, includes certification training, plant visits, viewing equipment in actual operation
and participating in "lessons learned" forums.
4. Labeling of wiring, pipes, controls, and panels showing such information as circuit
identification, direction/volume of flow, calibration instructions, expected ranges of meter
readings under various conditions, proper switch and damper positions, etc.

31. Describe your firm's approach to the performance guarantee.
APS Energy Services warrants for the term of contract following Substantial Completion (the "Guarantee Period") that the sites shall realize at least 100% of the savings detailed in the IGA that follow the schedules and maintain the comfort levels.
Measurement and Verification (M&V) is used to confirm that the new equipment and systems perform as projected and yield the projected savings.
Upon Substantial Completion of the work and at agreed upon intervals, APS Energy Services shall perform the M&V Plan for each Energy Conservation Measure (ECM) installed at each site to produce the M&V Report which will verify whether the ECMs are performing at a level that will support the Performance Guarantees.
In the event that the final M&V Report does not verify the expected energy savings in accordance with the M&V Plan, APS Energy Services shall repair or replace the ECM that is not performing at the required level, as identified in the M&V Report. APS Energy Services shall re-perform the relevant M&V work for the affected ECM and amend or supplement the M&V Report.
If the M&V Report demonstrates the work will achieve one hundred percent (100%) of the expected energy savings, then APS Energy Services shall have satisfied the energy performance guarantee obligations for the work under the Contract Documents.
If, after the opportunity to make corrections, the final M&V Report, as amended, indicates that energy savings for that period are less than expected energy savings for that year, APS Energy Services shall pay an amount equal to the sum of the present values of the difference between the expected energy savings for each year in the guarantee period and the energy savings shown for Year 1 in the final M&V Report. However, under no circumstances will the amount paid for the shortfall exceed the energy project cost.
This Guarantee is subject to the satisfactory performance by the City of its obligations including continued operation at the sites in accordance with the current scheduling information and maintenance of the facilities at the established comfort levels.
APS Energy Services offers guarantees that cover all program costs, including measurement and verification, as well as any maintenance contracting.
32. Does the guarantee cover the annual monitoring & verification and maintenance contract costs?
The guarantee can cover the costs that are included in the contract. APS Energy Services works with its Clients to customize our guarantee to their individual needs.

33. Describe the methodology proposed for ongoing monitoring and savings verification of each recommended project's performance, including the frequency of such efforts.
Energy savings calculations also mirror the measurement and verification (M&V) process. An
M&V plan, which includes the parameters that will be measured, the measurement time period,
the energy savings calculation methodology, savings adjustment methodology, and the
measurement equipment, is established and developed to fit the specific energy conservation
measure that is being evaluated. Each plan must meet one of the International Performance
Measurement and Verification Protocol (IPMVP) options or the Federal Energy Management
Protocol (FEMP) option criteria. The M&V plan for each Energy Conservation Measure (ECM) is
chosen carefully to meet the IPMVP or FEMP requirements, and to establish an accurate
timeline.
Once each ECM is installed, required post measurements will be taken and compared to pre-
installation measurements. Monitoring equipment is installed and data is collected. The collected
data from the monitoring equipment is then analyzed, trended and used to evaluate and verify
the predicted energy savings. Statistical analysis methods are also used to ensure statistically
significant and accurate results. The results are then compared against the baseline energy and
the predicted energy savings to verify the accuracy of the calculations. Adjustment to the
engineering calculations may then be applied to account for any changes in the baseline
conditions.
The energy or demand savings are determined by comparing measured demand or energy used
before and after implementation of an energy savings program. According to the 2002 edition of
IPMVP, it states that:
• Energy Savings = Baseline Energy Use — Post-Retrofit Energy Use ± Adjustments
The "Adjustment" term in this equation brings the energy use in the two time periods to the
same set of conditions. The conditions that most commonly affect energy use include weather,
occupancy, operating hours, equipment counts and ratings, temperature setpoints and changes
in the facility area. These conditions could have a positive or negative adjustment associated
with them.
The baseline conditions will be well documented in the M&V plan for each energy conservation
measure. The method of tracking and reporting changes to these conditions will also be established in the M&V plan. Once changes in these conditions are established, the baseline will
be recalculated to reflect the new changes if these changes have an effect on the baseline. The
energy savings will also be recalculated to reflect the new changes.
M&V can also be used to track the savings and ensure savings persist for the life of the measure.
If the savings are not being achieved, M&V can be helpful as a diagnostic tool to find the reasons
for not meeting the savings and what can be done to rectify the problem.
The City of Tempe will have the opportunity to choose the M&V option that best suits the cost,
timeline and benefit threshold needed by the City. APS Energy Services is able to perform savings
calculations using the methods preferred by the City.

The frequency of the M&V efforts will be determined by the most technically appropriate and cost-effective M&V approach agreed to by both City of Tempe and APS Energy Services and determined by the characteristics and applications of the technologies.
34. Briefly describe the maintenance responsibilities of your firm and City.
There are several aspects to long term maintenance services for energy savings persistence: assuring the equipment has the ability to perform its function to the best of its ability and then assuring that the equipment is being controlled in the most efficient manner. The ability to perform its function includes preventive maintenance services which includes alignment, lubrication, continuous power quality, and clean liquids and fluids to pass through the equipment. Clean heat transfer surfaces are also critical to the maintenance of energy savings. Predictive maintenance services can also be included to analyze vibrations that are an indicator of potential bearing failures. Most important to the energy savings is the continuous attention to how the device is controlled. It is only through periodic inspection that you can assure that the device is being controlled accurately and with the sequence of operations for the various modes of operation. APS Energy Services has several Client sites that we perform regular visits to confirm proper maintenance and energy persistence. Ongoing measurement and verification services are required by the State of Arizona and these will be in addition to the preventive and operating inspections as part APS Energy Services' offering.
35. Describe the types of services that can or must, be included in the maintenance contract. Comment on whether City's maintenance staff can perform these duties if desired, and describe any impact on the guarantee.
All Energy Conservation Measures are fully commissioned by trained professionals, followed by the delivery of specific Operational and Maintenance Manuals for all new and retrofitted equipment. All maintenance required would be dependent upon the type and complexity of equipment installed and/or retrofitted, and at the manufacturer's requirements for set intervals of maintenance. Assuming an adequate number of properly trained maintenance personnel on staff, the City of Tempe could perform these maintenance duties. Please note however, that failure to perform the scheduled maintenance on new and retrofitted equipment in accordance with the manufacturer's requirements may jeopardize equipment warranties and the City of Tempe's energy savings through reduced equipment efficiencies and service life.
36. Describe the required length of the maintenance contract if required and the relationship with the guarantee in the event that City chooses to terminate the maintenance contract prior to the end of the performance contract.
The required length of the maintenance contract is dependent upon the final decision of the City of Tempe. In most cases, the maintenance contract is structured to extend for the duration of the guarantee portion of the contract. If the contract does not define the guarantee or the City of Tempe determines a guarantee is not needed, the duration of the maintenance agreement may be based on yearly intervals or multiples of years, with the option to renew. If the City of Tempe decides to terminate the maintenance agreement prior to the end of the performance contract, and fails to provide scheduled maintenance in accordance with the manufacturer's

requirements, the City of Tempe would be at risk of decreased equipment performance and
service life that may reduce the prescribed energy savings as identified within the Technical
Grade Audit document.
37. Describe your willingness and experience/capability to provide services and prepare an application to achieve the Energy Star Label/LEED Certification on retrofitted buildings.
APS Energy Services is an Energy Star Partner and can and will provide all of the services required
to achieve an Energy Star Label for qualified buildings. We also have 2 LEED certified employees
that can assist in the development and analysis of points necessary to become LEED certified. We
will work with our Business Partners who have the experience and capability to prepare the
appropriate LEED applications.
38. Describe your willingness and experience/capability to calculate and report emissions reductions.
Calculating and Reporting emissions reductions as a result of energy efficiency projects ,as well
as, renewable energy generation is a standard in all reports developed by APS Energy Services.
These calculations are completed based on local utility generation mix and are specific to our
Client's locations in an effort to report as accurately as possible.
39. Describe how your firm would work with the City's facility manager to coordinate installation and avoid conflicts with the building's operation and use.
Nearly all of APS Energy Services' Clients are located in publicly occupied facilities where specific
coordination is required with the Client, local utilities, subcontractors, equipment suppliers and
facility personnel to best accommodate the needs of the Client, its staff and visitors to cause
minimal, if any, disruption. APS Energy Services will work with the City to coordinate the
construction schedule to occur before or after occupied times. This scheduling allows the project
schedule to be maintained without having to disrupt workdays and APS Energy Services ensures
that its subcontractors and equipment suppliers will follow the established construction
schedule.
40. Who will control the purchase of parts and what procedures would be in place to guarantee the best value to the City?
APS Energy Services will control the purchase of parts and will competitively bid for best pricing
through approved vendors to supply parts as needed for the period of the maintenance
agreement, with any escalation established based on the maintenance period.
41. Describe your company's process to solicit bids on equipment/labor or to ensure price/cost competition and the best value for the City.
APS Energy Services will ask the City of Tempe for the name of two or three contractors who
have performed well for the City in the past for each of the trades. APS Energy Services will help

the City of Tempe standardize installed equipment, thus helping to lower the cost to maintain City facilities. APS Energy Services will prepare specifications, scope and drawings to obtain subcontract work and materials for the City. APS Energy Services strongly believes in keeping its business in the communities where the company is invited to work by using local companies as subcontractors as often as possible.
APS Energy Services will assume full responsibility for all project work and services performed by our subcontractors. Our subcontractor team will adhere to all provisions and conditions in this RFR.
42. Describe any major changes in operations or maintenance of the facilities that your firm foresees based on the information provided.
Based upon the preliminary energy savings ideas presented in the Preliminary Energy Audit located in the Appendix, some of the final recommended energy conservation measures may include changes to operations and maintenance of the STWTP. This is where the value of Carollo Engineers as part of our team is significant, as they will be cognizant of how changes in operation have the potential to influence the primary objective of the STWTP, which is to provide safe drinking water at the service level Tempe's customers have come to expect. Specific examples of possible operational modifications include the following:
• Frequency and timing (optimization) of solids blowdown events.
• Slight modifications to sodium hypochlorite generation operations.
• Modify the UV dose control algorithm to preferentially operate at more efficient lamp power settings.
• Provide a new control algorithm for operation of the Finished Water Pump Station (FWPS), based upon automatic control of pump speed and on/off operation to maintain the desired operating setpoint discharge pressure.
• Modify the power control system to incorporate the use of an on-site biodiesel fueled turbine generator for peak power demand.
• Install and use a complete power monitoring system, and allow operators to make operational adjustments using the monitoring system feedback.
The greatest potential for energy and associated cost savings is at the FWPS. However, to develop fully implementable Energy Conservation Measures, it will be necessary to evaluate how changes to the operation of the FWPS affect the ability to provide appropriate pressure and flow throughout the distribution system. That is, modifications of the operation of the FWPS to achieve power savings at the STWTP will need to be matched with modifications to the operation of the distribution facilities. It is not known if this type of evaluation is anticipated or expected as part of the performance contract, but our recommendation is to provide you with a holistic analysis that will result in a response plan that balances total energy savings without sacrifice to the provision of safe drinking water.
