1.0 EXECUTIVE SUMMARY
SIEMENS Building Technologies, Inc. (SIEMENS) is pleased to present the City of Saratoga with
the following Preliminary Study that identifies a set of turnkey improvements that will reduce energy,
water consumption and operating costs for the city. The minimum potential project represents an
average annual savings of $80,000 or $1.2 million over a 15 year period.
After a preliminary evaluation of nine of the City's facilities and existing utility bills, SIEMENS found
that the City has made a significant number of energy efficiency improvement measures previous to
this Preliminary Study, and has demonstrated itself to be forward- looking with respect to cost and
energy savings.
SIEMENS found numerous opportunities to improve energy and water efficiency. Energy, water
and operational savings would be realized by implementing projects involving heating and cooling
improvements, upgraded lighting systems, irrigation improvements, and other facility improvement
measures (FIMs). These findings are a result of site visits and technical analyses and reflect
SIEMENS' interest in delivering the most cost effective, state -of- the -art, and reliable energy, water
and operational savings solutions possible.
PROJECT SUMMARY
Total Project cost ranges from $1 $4.2 million (Table 1).
Much needed facility upgrades would be accomplished.
Options 1 and 2 are mostly self- funding
Table 1: Overview of Project Potential
There are potentially significant additional energy, water and operational savings and environmental
benefits associated with the project which will be studied in more depth at the Detailed Study phase
of the project.

SIEMENS
SIEMENS will utilize its significant resources and expertise to implement facility improvements,
providing the following benefits to the City of Saratoga:
Significantly reduce energy and water consumption, as well as associated greenhouse
gas emissions.
Significantly reduce operational expenditures with respect to heating, ventilation, and air
conditioning maintenance and replacement costs
Increase comfort levels and environmental control, benefiting building occupants
Increase lighting quality and improve the working environment
Improve exterior lighting in the parking lots, common areas and city street lighting
Extend existing facilities management capabilities with SIEMENS Service Staff providing
service and technology support 24 hours a day, 7 days a week.
Provide a financing solution so that much of the energy services program is self funding
Guarantee the energy, water and operational savings so there is no risk to the city in
accomplishing the facility improvement measures
Note: These energy opportunities are preliminary in nature and typically have a confidence band of
+1- 20 contingent upon modifications to the scope of work as directed by the city. A detailed
study must be made to verify the projected savings and project implementation costs. This is
considered to be a very conservative estimate. SIEMENS' energy estimates are based upon our
previous experience.

ENVIRONMENTAL IMPACT
In addition to reducing energy consumption, these turnkey improvements give the City of Saratoga
the opportunity to improve environmental performance of its buildings, both in terms of increasing
building occupant comfort levels while reducing harmful environmental impacts. Now more than
ever, State and Federal agencies are promoting the need to reduce energy consumption, and are
offering money in the form of incentives, rebates, and low interest loans to encourage energy
efficiency and renewable energy generation. These programs increase the economic feasibility of
the project, and SIEMENS can guide the city in taking advantage of these programs.
The positive impact this project will have on the environment is quantifiable. While PG &E has a
higher percentage of renewable energy in its portfolio than most utilities, much energy generated
still comes from burning fossil fuels. By reducing your energy consumption, fewer fossil fuels are
consumed which means less harmful emissions. Commercial buildings generate 18% of U.S.
carbon dioxide emissions. (Source: www.energystar.gov). By implementing the proposed Option 2
energy project, the city will save significant kWh of electricity, therms of gas and ccf of water.
Saving this electricity and gas will result in significant savings in CO emissions.

ELECTRICITY
Pacific Gas Electric (PG &E) provides electric service to a majority of the facilities in the City of
Saratoga. Each facility has at least one electric meter on site. These accounts will be discussed
briefly at the end of this section. The most recent twelve (12) month data available to SIEMENS
was the electricity billing data for the period of January 2008 through December 2008.
SIEMENS
PG &E provides electrical service to the city on the Al P, A6, A10S, E19SW, LS -1 and LS -2 rate
schedules. During summer, the on -peak period is from noon to 6:00 PM, part-peak from 8:30 AM to
noon and from 6:00 PM to 9:30 PM and off -peak is from 9:30 PM to 8:30 AM. During winter the
part-peak is from 8:30 AM to 9:30 PM and off -peak is from 9:30 PM to 8:30 AM. Weekends and
holidays are treated as off -peak periods. LS -1 and 2 rates are a stipulated amount when there is no
meter attached to the City's street lights (typical). PG &E assumes that there are 11 burn hours per
day, 365 days per year totaling 4,015 burn hours per year.
During the period of January 2008 through December 2008, the City of Saratoga spent a total of
$88,487 on electricity at: City Hall, Planning /Engineering/Theatre, Community /Senior Center, Corp.
Yard, North Campus, Warner Hutton House, Hakone Gardens. The total electric spend at the
Library for that same period was $165,761. The average electricity cost, or blended rate for the
period of January 2008 through December 2008 was $0.16 /kWh. The rate structures and charges
are listed in Appendix B.
Lighting and Landscape Districts have the potential for significant electrical and operational savings
by replacement of existing fixtures with either LED or Induction technology.

2.5 ENERGY USE BENCHMARKS
SIEMENS performed a benchmarking analysis of the city's facilities. Benchmarking offers a high
level overview when comparing buildings of similar type, size and function. Buildings are
normalized by comparing energy use on a "per square foot" basis, known as energy usage intensity
(EUI). EUI information enables the development of a square foot index, which is then compared to
similar buildings in the region and identifies which buildings have the potential for greater energy,
water and operational savings. Based on staff interviews, utility and operational data provided,
SIEMENS calculated a benchmark analysis seen in the figures below:

3.0 ENERGY PROJECT OPPORTUNITIES
3.01 Energy Management System
An energy management system (EMS) manages energy consumption and delivery of
optimal lighting and thermal conditions by providing integrated control and monitoring of
fans, pumps, HVAC equipment, dampers, mixers, and thermostats. An energy management
system achieves optimal levels of occupant comfort while maximizing the energy efficiency
of the building(s). Control strategies such as this would be considered when upgrading the
HVAC equipment as well as Street Lighting, and Exterior /Interior Lighting upgrades at the
selected Saratoga facilities and locations.
3.02 PC Power Management
Most (if not all) of the facilities operated by the City of
Saratoga have computers on its network. Currently, the
network does not have power management capabilities,
therefore, we are considering a potential energy saving
strategy to upgrade the existing system to that of a PC Power
Management system. Realized savings can include an
annual savings of 200 kWh per each personal computer.
3.03 Interior Lighting Upgrade
The intent of this modernization measure is to reduce energy costs by
increasing lighting efficiency and to increase occupant performance by
maintaining proper lighting levels. Occupancy sensors can curtail
energy consumption by ensuring lights are turned off during unoccupied
hours. A detailed lighting audit is recommended to better understand the
savings potential of this measure.
3.04 Exterior Lighting Upgrade Street Lighting Upgrade
Induction and LED lamps save energy. The intent of this modernization
measure is to reduce energy costs by increasing lighting efficiency
while maintaining proper lighting levels. A detailed exterior street
lighting audit is recommended to better understand the savings
potential of this measure.
3.05 Exit Sign Upgrade
There are several benefits associated with this upgrade, including
reduced energy consumption, longer fixture life, and reduced
maintenance costs. Upgrading exit signs from incandescent to LED
can save an estimated 300 kWh per exit sign fixture. A detailed exit
sign audit is recommended to better understand the savings
potential of this measure.

models. It is recommended to replace these motors with premium efficiency models.
Newer, premium efficiency motors will be in the 90- percentile efficiency range. The intent of
the measure is to reduce both energy consumption as well as demand through the use of
higher efficiency equipment. A detailed motor audit is recommended to better understand
the savings potential of this measure.
3.07 Window Film
Window film helps conserve energy and decreases a building's green house gas emission
levels. Window film lowers energy consumption, thus lowering building operating costs.
Window film helps keep the inside of a building cooler and at a comfortable temperature
during the hot summer months. It acts as an insulator during the cold winter months helping
keep a building at a comfortable desirable temperature. The energy efficiency of a building
will increase by reducing the heating and cooling loads.
3.08 Plug Load Controller
A plug load controller is an energy saving control system that provides maximum surge and
noise suppression while keeping plug load equipment off when there is no occupancy.
Often times plug loads remain on while an office or cubicle is unoccupied during work hours,
or even in the evening. The plug load controller saves energy by keeping plug load
equipment off while employees are at meetings or off to lunch, etc. Typical construction is
invasive and looks similar to that of a eight outlet power strip.
3.09 Thermal Storage
A thermal storage module can be paired with a standard air conditioning unit to reduce the
air conditioning demand for small to mid -sized commercial buildings. The system is
designed for easy deployment and requires no modification to existing ductwork or structure.
The system utilizes off -peak power to freeze water within an insulated storage tank to store
cooling capacity at night for use during the next day. This eliminates the need to run the
energy intensive compressor during peak daytime hours. Air conditioning energy demand is
typically 40 -50% of a buildings electricity use during expensive peak hours. This will
significantly reduce the electrical consumption of a building during the day. Additional
analysis is necessary to determine the viability of specific applications.
3.10 HVAC Unit Upgrades
There are currently five air conditioning units
at the City Hall Complex facilities (City Hall
Admin. /Engr /Community Development) that
should be replaced. Three of the units are
Trane units, and the other two units are BDP
Co. The Senior /Community Center has six air
conditioning units that should also be
replaced. The units at the Senior /Community
Center are all BDP Co. units. All eleven units
Confidential and Proprietary
1
mentioned are over 15 years old and have exceeded the efficient life expectancy of an air
conditioning unit. The intent of the measure is to reduce energy costs through the use of
higher efficiency equipment.
3.11 Vending Miser Controllers
By installing energy governing controls on the four vending machines,
runtimes can be curtailed up to 50% saving energy and operational
costs to maintain the compressor. The Vending Miser controller
detects occupancy and provides efficiency controls for each vending
machine according to occupancy.
3.12 Water Conservation
Water conservation measures can be implemented on
a strategic basis to reduce operating costs at both the
LLD's and at Hakone Gardens' landscape irrigation
system. Weather smart automated irrigation controls
use weather factors such as soil infiltration and rainfall
intensity which are compared to determine the exact
effect weather has on irrigation needs. Ordinary
irrigation systems cannot adjust to changing weather
conditions. Ordinary irrigation systems generally
overwater the landscape causing expensive property
damage (figure), and high water bills. Additional
analysis is necessary to determine the viability of specific applications, however, locations
such as the Bellgrove District, The Orchard and Hakone Gardens are the three locations
that offer the most potential.
3.13 Photovoltaic System
Siemens can install solar power panels to provide an efficient and
easy -to- install source of solar electricity. A preliminary calculation
yielded a system capable of offsetting 100% of Saratoga's annual
electric consumption. The system can help reduce power
consumption from the utility grid during peak demand rates.
Systems can be installed on rooftops, in designated ground areas,
and in parking lot structures. These systems further demonstrate
the city's commitment to environmental initiatives. Installation of
these systems helps to reduce greenhouse gases, positively
impacts global warming, reduces acid rain types of emissions, reduces your susceptibility for
utility -based energy price increases and reduces the consumption of fossil fuels.
3.14 Solar Water Heating
Solar Water Heating (SWH) can offset your annual gas
utility bill by heating up your domestic hot water with energy
supplied by the sun. The addition of this system can impact
tasks ranging from hand washing to dish washing. Upon
further investigation, we will find the correct locations and
Confidential and Proprietary
19
system sizes where the SWH will have the greatest impact and lowest pay back rate.
Possible sites for a viable SWH system include Planning and Engineering, the Theater, City
Hall, the Library and the Community /Senior Center.
3.15 Refrigerator and Freezer Optimization
Cooling starts when the compressor of the refrigerator or freezer turns on. Run time on the
energy- consuming compressors for the typical refrigerator and freezer comes from a sensor
in the unit that senses change in air temperature. However, items in these units are food and
liquid items. Fluctuating air temperature due to doors opening and closing sends a signal to
the compressor to turn on and cycle the system to assist in cooling. Air temperature rises
faster than food temperature and an optimization device can be implemented to more closely
mimic actual food temperature rather than air temperature. Considerable operational savings
from not having to cycle the compressors in these units can be quantified as well as lower
money spent in your annual electrical bills can also be achieved.
3.16 Cool Roof
Siemens surveyed two sites that are candidates for a cool roof. These
two sites are the Senior /Community Center, and the City Hall Complex
(Engr /Planning /Admin). A cool roof also known as a white roof is a
highly reflective and emissive roof coatings that stays 50 to 60 degrees
F cooler in the summer sun. A cool roof reduces energy costs,
improves occupant comfort, and increases the life cycle of the roof.

lighting audit (DEA) to determine the existing lighting levels existing at the Library.
Photovoltaic System: The push for cities to "go- green" is now mainstream and the City of
Saratoga has aggressively already accomplished initial Facility Improvement Measures
(FIMs) at their existing facility. This helps reduce the initial expense for purchasing a larger
photovoltaic (PV) system by already lowering the annual utility bill. Under the Aggregate
Net Meting (AB 2466) scenario, the City has the opportunity to install PV at multiple city
owned locations and utilize the energy generated to the rest of the existing facility electrical
meters. Siemens recommends a DEA to determine the size of system and AB 2466
scenarios.

6.0 CONCLUSIONS AND NEXT STEPS
This Preliminary Proposal has identified areas where the city can reduce energy, water, and
operating costs resulting in numerous other benefits. The next step in the project development
process is to perform a detailed energy audit of the facilities. A comprehensive analysis will provide
proposed equipment descriptions, specifications, detailed construction information, cost and
savings projections, financing terms, a life -cycle cost analysis, and implementation schedule.
SIEMENS will address all aspects of the project including operation and maintenance, training, and
measurement and verification to ensure that projected savings are fully realized. SIEMENS will
also thoroughly consider the following factors:
Available financial resources, including federal, state and utility incentives
Financing options for customer consideration
Project development and project management requirements
Training of facility operators
Long range operation and maintenance
SIEMENS' experience has shown that the preliminary analysis in this proposal is an important first
step in helping customers better understand their facility's energy efficiency profile. However, the
most significant benefit results from helping customers implement the energy, water and operational
savings solutions that are determined during a detailed energy audit. SIEMENS has dedicated staff
experienced in developing the most cost effective energy program for each customer. SIEMENS'
licensed and skilled professionals will ensure that projects are implemented in a timely manner with
minimal disruption to daily activities.
We now propose that the city and SIEMENS jointly develop a customized Scope of Work on which
to base the detailed analysis. A sample Letter of Intent will be provided as a starting point for this
discussion.
The final outcome of the entire process will be a co- authored energy program that is in the best
interests of the city. Here are some key characteristics of SIEMENS' unique and rigorous
approach:
No Up -Front Capital. All costs related to the implementation of the recommended solution,
such as feasibility study costs, design and engineering fees, project management, construction
costs, operations and maintenance training, monitoring of results, and verification of savings
are included in SIEMENS' integrated solution. Therefore, there are no capital requirements
from the city at any time in the development or installation of the project.
Long -Term Comprehensive Perspective. SIEMENS evaluates and considers all cost
effective measures and is not limited to short -term payback projects or constrained by any
product preferences. We will work with the preferences of the city as it relates to contractors
and /or equipment.
Hassle -Free Implementation. Since the SIEMENS solution is an integrated arrangement, the
city does not have to allocate existing personnel to manage the various steps involved in
performing energy efficiency improvements such as feasibility studies, designing and installing
equipment, training personnel, and monitoring the systems' performance.
Partners in Process. SIEMENS will always include the city management in key milestone
decisions throughout the project and will ensure a co- authored solution.

Performance Standards. SIEMENS will oversee the quality of service provided and will
ensure that vendors and subcontractors follow specific and strict performance standards.
Comprehensive Warranty. SIEMENS will provide overall warranty coverage for a period of
twelve months from the date of substantial completion for each end -use measure.
Follow -Up Reports to the City. SIEMENS will provide the city with a summary of the
project's performance on a periodic basis.
Capturing Energy Savings from Capital Improvement Projects and Avoided Capital
Costs. SIEMENS can capture energy savings from current city projects pending that are not
implemented before a contract is signed, and roll those savings into the performance program
to allow for paying of projects where shortage of funds exists.

The demand charges are not time -of -use and the A10 TOU rate structure for demand is as follows:
Demand /kW
Maximum Peak
The E -19SW (Non -FTA Rates) rate structure provided by PG &E charges for time -of -use consumption
kWh as well as demand kW. This benefits facilities most likely to use a significant percentage of their
electricity during the off -peak period.
Electricity /kWh (E19SX rate without tax)

Demand is measured and averaged over 15- minute intervals. "Maximum" demand is the highest of all
the 15- minute averages for the billing month. "Maximum Peak" is the highest of all the 15- minute
averages during the peak period. The E19SX rate structure for demand is as follows:
Demand /kW (E19SX rate without tax)Summer
