TO: WILLIAM A. HUSTON, CITY MANAGER
FROM: DOUGLAS S. STACK, ACTING DIRECTOR OF PUBLIC WORKS/CITY ENGINEER
SUBJECT: ADOPTION OF AN ENERGY EFFICIENCY AND CONSERVATION STRATEGY
SUMMARY
In order to be eligible to receive grant funding under the Energy Efficiency and
Conservation Block Grant (EECBG) Program, all entities receiving direct formula grants
from the U.S. Department of Energy are required to develop an Energy Efficiency and
Conservation Strategy (EEGs). The EECS identifies strategies to achieve the purposes of
the EECBG program. The City of Tustin's total eligible grant allocation is $677,300.
Presently, the application process has secured $30,000 of the allocation to develop our
Energy Efficiency and Conservation Strategy (EECS) attached for City Council
consideration.
RECOMMENDATION
It is recommended that the City Council adopt Resolution No. 10-14 adopting the Energy
Efficiency and Conservation Strategy and authorizing acceptance and execution of the
EECBG upon award by the U.S. Department of Energy.
FISCAL IMPACT
Failure to approve the recommended action will result in forfeiture of the remaining federal
grant funding in the amount of $647,300.
BACKGROUND
The American Recovery and Reinvestment Act (ARRA) of 2009, appropriates $2.7 billion in
funding for the Department of Energy (DOE) to issue/award formula-based grants to states,
U.S. territories, units of local government, and Indian tribes under the Energy Efficiency and
Conservation Block Grant (EECBG) Program. The purpose of the EECBG Program is to
assist eligible entities in creating and implementing strategies to reduce fossil fuel
emissions, reduce total energy use and improve energy efficiency. As a stipulation of grant
funding eligibility, each entity is required to develop an Energy Efficiency and Conservation
Strategy (EECS).

DISCUSSION
The City of Tustin is eligible for the allocation of $677,300, in Energy Efficiency and
Conservation Block Grant (EECBG) funds. Of the $677,300, the City has encumbered
$30,000 for its preparation of the Energy Efficiency and Conservation Strategy (EEGs).
The five City facilities that were initially identified, inventoried and evaluated to reduce total
energy use and improve energy efficiency were Civic Center, Columbus Tustin Gym,
Senior Center, Youth Center and Field Services Yard.
During the process of developing the City's EECS several conservation projects were
reviewed including lighting retrofits, control systems for lighting and heating ventilation and
air conditioning (HVAC), water conservation (flush valves, waterless urinals, & faucet
aerators) and solar (photovoltaic) projects. Many of the projects examined produce long-
term savings and several have already been incorporated into normal maintenance
activities to reduce energy costs and improve energy efficiency.
The recommended EECS identifies the following two priority projects for further
consideration and full utilization of available EECBG funding:
1. Photovoltaic Installation at Columbus Tustin Gymnasium
2. Tustin Energy Efficiency Building Permit Fee Rebate Program
The photovoltaic installation at Columbus Tustin Gymnasium will be a project designed to
generate the energy demand of the facility from solar at an estimated cost of $567,000. In
addition, staff will further apply for a rebate via the California Solar Initiative (CSI) that will
potentially allow for the city to receive a governmental incentive rebate for every kilowatt-
hour generated in excess of demand. The current incentive rebate is equal to $0.32 per
kilowatt-hour. The Tustin Energy Efficiency Building Permit Fee Rebate Program will be
further developed in cooperation with the Community Development Department to help
offset plan check fees, permit fees and inspection costs related to qualified improvements
for:
• New solar panels or Photovoltaic system Installation (avg. $550 each permit)
• New tankless water heating system Installation (avg. $50 each permit)
• Energy efficient air conditioning and ventilation systems upgrade -
overthe counter permit -one inspection (avg. $50 each permit)
• Energy efficient furnace upgrade -over the counter permit -one
inspection (avg. $50 each permit)
In order to maintain EECBG funding eligibility, staff is recommending the adoption of
Resolution No. ,10-14 as presented.

2. METHODOLOGY
The City of Tustin is eligible for the allocation of $677,300, in Energy Efficiency and
Conservation Block Grant (EECBG) funds. IMPACT Industrial Services has been engaged to
develop an Energy Efficiency and Conservation Strategy (EEGs) for five municipal buildings
owned by the City. This plan will identify potential energy conservation projects and provide the
City of Tustin with a budget and forecast for implementation.
The five City facilities that were identified, inventoried and evaluated to reduce total energy use
and improve energy efficiency were:
• Civic Center
• Columbus Tustin Gym
• Senior Center
• Youth Center
• Field Services Yard
This EECS report provides a system level survey of the buildings' structure, process, and
equipment, and identifies areas for savings. Basic information is obtained regarding energy
usage and utility issues, and a visual inspection is performed during the walk-through of the
facility to determine if there are operational savings opportunities. The scope of this work
includes:
• Review of energy bills from the previous 12 months.
• Interview of site personnel
• Breakdown of utility use within the property by major system.
• Compare facilities energy use index (EUI) against industry standard or peer groups.
• Development of a list of Energy Conservation Measures (ECM) for each of the major
energy-consuming systems, envelope, HVAC, lighting, power, and process.
• Develop a prioritized plan and forecast of the impact of the identified ECMs.
The findings are presented in this EECS report, to facilitate decision making resulting in a
prioritized action plan as part of a comprehensive energy management plan.
The EECS is a reconciliation of a "top down" analysis of utility bills with a "bottoms up"
evaluation of major systems' components and their operations. Major equipment specification
and operational profile data is gathered to develop system level estimates of utility usage that
can be then adjusted for actual annualized utility use.
The load factor concept utilized throughout this energy analysis is simply the ratio of average
actual consumption to the maximum potential consumption at full load. Load factor provides a
methodology to account for variance in operational profiles as system loads vary due to actual
throughput requirements (such as customer orders).
Electrical usage of lighting systems within the buildings are estimated by means of the actual
system inventory by fixture type and known hours of operation. For those instances where a
detailed lighting count is not feasible, lighting densities (in Watts /square foot) may be sampled
for representative areas and then extrapolated across the entire building space.
City of Tustin Energy Efficiency Conservation Strategy 2 1/12!2010
The energy consumption associated with HVAC equipment is bounded by weather dependent
use that is evident on utility bills, typically correlated to weather variables such as heating or
cooling degree days. Such correlations are easily observed in the seasonal variance in natural
gas usage due to winter heating loads. Such profiles allow for the evaluation of statistical
dependence on weather, leading to well defined breakouts of "base load" operations such as
kitchen usage. This total system usage may then be allocated across individual equipment by
size and functionality within the system. A similar analysis may often be performed for the
space cooling related consumption on the facility electrical usage.
With the lighting and HVAC systems modeled, the remaining loads are estimated from
nameplate data, staff interviews, and observation. As with all major systems, these
incrementally built up models are then normalized to meet the boundaries set by actual energy
usage documented on the utility billings.
Construction costs for the recommended ECMs are developed from contractor quotes, RS
Means estimates, and benchmark experience. While individual projects' final costs and
savings may vary from the results presented in this report, it is anticipated that the level of
accuracy across the entire portfolio of projects will exceed a schematic budget estimate level.

The energy use index (EUI) is based on the total annual energy (electrical and fossil fuel)
usage per square foot for each building. When normalized for the geographic area and local
weather conditions, this may then be used for comparison to other peer facilities as an
evaluation of the building performance.
The average unit rates for utilities calculated from the billing statements are presented below.
These rates are used for estimating the cost savings from the projects identified as part of this
initiative.

5.'I SOLAR PHOTOVOLTAICS
As fossil fuel prices continue to
grow and install prices drop,
renewable energy sources
continue to be a growing
contributor to the country's
energy supply. Incentives from
utilities and state and federal
sources also drive down these
first costs and can provide both
positive cash flow and
environmental impacts
throughout the life of the
equipment.

A review of such opportunities was performed for the City buildings. The CT Gym has been
identified as an excellent candidate for solar generated electricity. The pitch, open area, and
orientation of this roof allows for up to 106 kW of fixed solar arrays to be installed.
The economic climate within California is also a significant contributor to the viability of this
project; rebates in excess of $258,000 are available for this installation. In addition, staff can
also apply for a rebate via the California Solar Initiative (CSI) that will potentially allow for the
City to receive a governmental incentive rebate for every kilowatt-hour generated in excess of
demand. The current incentive rebate is currently equal to $0.32 per kilowatt-hour.
This project can provide a positive cash flow scenario throughout its 25 year lifespan, creating
potential monies to be used in the implementation of other energy conservation or sustainable
projects.
Appendix A includes the solar proposal and economic forecast provided by Garland Energy for
the City of Tustin.

5.Z LIGHTING UPGRADES
The majority of the buildings at the City of Tustin have been upgraded to T8 linear fluorescent
lamps and electronic ballasts. T12 linear fluorescent fixtures with magnetic ballasts and
incandescent lamps are found sporadically throughout the campus. There are many
fluorescent exit signs are in use (some are just paper signs). Motion sensors are not used with
any frequency.
The following is an overview of current lighting technology that will be recommended at the
buildings.
Compact Fluorescent Lamps
Compact fluorescent lamps (CFCs) are now in the mainstream with excellent color rendering,
new coating technologies and less mercury to dispose of once the lamp is replaced. Additional
benefits include:
• Besides saving energy, these lamps are instant on and last 8,000 to 25,000 hours,
depending on the lamp specified (compared to the A lamps currently used that last
1,000 hours).
• CFCs come in a wide variety of shapes and colors (referred to as color temperature in
degrees Kelvin). Color temperatures are available from a very warm 2,700 K, which is
the same as incandescent lamps, to a very blue 5,100 K.
Replace any existing incandescent lamps with CFCs.
T12 Linear Fluorescent Conversions to T8 with Electronic Ballasts
Any remaining T12 linear fluorescent lamps with magnetic ballasts should be converted to a T8
system with electronic ballasts.
Magnetic ballasts operate at 60Hz (cycles per second), the frequency of the AC voltage they
run on. About 25% of the population is sensitive to magnetic ballast flicker and hum and
actually can become physically ill, with symptoms such as headaches, nausea, itching and
burning eyes, tension, eye fatigue, and general fatigue. Operating at 60Hz, magnetic ballasts
may cause a stroboscopic effect with any machinery which has parts, such as pulleys or gears,
running at speeds that are a multiple of 60Hz. The stroboscopic effect will cause the machine
to appear motionless, which could be a hazard. Electronic ballasts work on high frequency,
around 25,000 Hz, which eliminates bothersome flicker and hum and improves the work or
classroom environment.
Lumen depreciation is the amount lumen output is
decreased over the life of the lamp. A major advantage
of converting to high efficiency T8 lamp systems is they
only lose 5% to 10% of light output (lumen
depreciation) over their life expectancy compared to a
T12's typical 30% lumen deprecation. As a result,
normal failures will tend to be close together for future
re-tamping purposes.
Replace any T12 lamps and magnetic ballasts with
newer T8, 25 Watt lamps and electronic ballasts.

Fifth Generation Linear Fluorescent Lamps
Fifth generation reduced-wattage T8 lamps are designed for fluorescent luminaire retrofits
where standard 32 W/T8 lamps would provide more light than is needed. These lamps are
available in 25, 28 and 30 W models and, in a majority of the cases, can replace the original 32
W lamps with 24% lower energy consumption than standard 32W/T8, but lumens are reduced
only 6%
Replace current T8 lamps with reduced wattage Fifth Generation lamps (the existing ballasts
do not need to be replaced). These replacements should be part of a group re-tamping when
the current T8's light output has depreciated to unacceptable levels or when maintenance is
starting to replace multiple lamps.
Lighting Occupancy Sensors
There were very few lighting occupancy sensors throughout the
City buildings. Suitable spaces include restrooms, conference
rooms, and private offices.
Utilize dual technology occupancy sensors that respond to both
movement and noise (infrared and ultrasonic) be installed so there
is little chance of accidentally turning the lights off in occupied
spaces. The figure at right demonstrates the dual technology
occupancy sensor functionality.
Exit Signs
Upgrade exit signs not using LED technology to LED.
Exterior and High Ceiling Lamps
Continue to replace high pressure sodium, mercury vapor, and metal halide lamps induction
lamps (with LED fixtures as an alternative). The energy savings from using the induction fixture
is greater than 50% but the leading advantage in an application such as this is the 15 year
maintenance free operation. For indoor applications, multi-lamp linear fluorescents may also be
considered.
Lighting Run Hours used for Analysis
Civic Center: Based on a run time of 12 hours per day for 250 days per year, except for
Police Department (24/7).
• City Yard: Based on a run time of 12 hours per day for 250 days per year.

5.3 HVAC AND BUILDING AUTOMATION OPPORTUNITIES
General Recommendation -DDC Based Controls
Continue to convert HVAC controls from rudimentary (pneumatic, thermostatic, and timer)
based controls to direct digital (DDC) controls to provide the capability for dynamic control
strategies.
A campus-wide energy and environmental standard
should be set by senior administration and enforced by
the facilities staff. Occupied and un-occupied set points
and hours of operation should be defined and
implemented through the Apogee system. Space
conditions should be set to satisfy and industry
standard, such as the ASHRAE comfort zone definition
(depicted) or the Fanger comfort model. The level
(maximum deviation and duration) of night and
weekend set back strategies should be evaluated for
each building on a trial and error basis to balance the
greatest savings opportunity with optimal recovery time
from this "reset" state.

OPEIUIty[ IEYP[M*IMIF. "f
Demand Control Ventilation (DCV) can reduce the cost of operating an HVAC system by
matching the (unconditioned) outdoor air intake to the actual needs of the space. ASHRAE
standard 62.1 allows for the use of Carbon Dioxide (C02) sensors to evaluate the space need
and then to reset the outside air dampers using a building's automation system. We
recommend that sensors be installed and programming put in place to implement this strategy.
Re-commissioning of the dampers and actuators are recommended.
As part of the building assessments, a thorough review of the existing mechanical systems was
performed to evaluate the ECM opportunities at each building. An overview of the findings and
recommendations are presented below.
Civic Center
The Civic Center area consists of 4 VAV roof top DX units. The VAV units have fixed discharge air set
points and dry bulb economizers that appear inoperable. The dampers look to be in fair shape. The
supply fans contain inlet guide vanes as a form of fan capacity control.
City of Tustin Energy Efficiency Conservation Strategy 20 1/12/2010
A boiler is used to provide heating to the exterior zones and appears to run continuous. The boiler has a
fixed set point of 140 degrees and no apparent OSA lock out.
Potential VAV System ECM Opportunities:
• Discharge Air Reset From return air temp or VAV terminal load(Zone control required)
• VFDs for supply fans and static control.
• Differential temp economizer enable with OSA Lock out.
Demand Control Ventilation
• Global and Holiday scheduling.
• Zone control at each VAV box to implement and provide digital control to zones. Provide
occupancy sensors for each zone. Allowing zones to be controlled by occupied, standby and
unoccupied set point. Also data terminal load information can be provided to accurately control the
static control algorithm as well as the Discharge air control.
• OSA reset for boiler loop temperature set point
• Energize Boiler based on demand driven by Terminal load of VAV units and OSA temperature.
The civic center also utilizes single zone constant volume package units to serve some areas of the
complex. These units are generally controlled with mercury bulb mechanical thermostats or electronic
non-programmable equipment (no scheduling capabilities). Twelve hour wind up timers are also deployed
for simple schedule control. The economizers did not appear to function efficiently as we tested the
operations on a day in which mechanical cooling was not required.
Potential Single Zone ECM Opportunities:
• DDC unitary control for event scheduling or occupancy based control.
• Retro-commission economizer operations.
• Demand control ventilation on units that serve area that vary in occupancy. (Council chambers
and community center.
Citv Yard /Field Services
The field services buildings use constant volume, single zone rooftop units. The units are currently
operated on commercial 7 day programmable thermostats. The Trane equipment has functioning
economizers but the carrier unit does not. The unit serving the pole barn also does not contain an
economizer.
Potential ECM Opportunities:
• DDC unitary control for event scheduling or occupancy based control.
• Retro-commission economizer operations.
CT Gym
The Gym utilizes multiple constant volume roof top units that are controlled with mercury bulb thermostats
and 12 hour wind up timers. All units have economizers; however, none are in operation and require
some damper repairs or modification to remove obstructions from the intakes.
Potential ECM Opportunities:
• DDC unitary control for event scheduling or occupancy based control.
• Retro-commission economizer operations. (repair economizers)
• Demand Control Ventilation
• Occupancy sensors and standby, occupied and unoccupied set points.
City of Tustin Energy Efficiency Conservation Strategy 21 1 /12/2010
Youth Center
The youth center HVAC equipment consists of 3 carrier rooftop units controlled by 7 day programmable
stats. The economizers do not operate on these units as the dampers are in poor shape. Occupancy
varies in this facility with class room schedules.
Potential ECM Opportunities:
• DDC unitary control for event scheduling or occupancy based control.
• Retro-commission economizer operations. (repair economizers)
• Demand Control Ventilation
• Occupancy sensors and standby, occupied and unoccupied set points.
Senior Center
The senior center uses multiple constant volume rooftop units. Two of the units utilize an electronic
zoning system. One of the zoning system units has no scheduling mechanism for the unoccupied
operation. Unit occupancy control is provided by 12 hour wind up timers and mechanical mercury bulb
thermostats. The new carrier unit uses a 7 day programmable thermostat for temperature control and
occupancy. These units have been slated for replacement.
Potential ECM Opportunities:
• DDC unitary control for event scheduling or occupancy based control.
• Demand Control Ventilation
• Occupancy sensors and standby, occupied and unoccupied set points.
Appendix D provides an inventory of the major mechanical equipment serving the buildings
addressed within this report.
5.4 VENDING MACHINE LOAD CONTROLLERS
Vending machines are located within several buildings in the City portfolio. These units operate
continuously, regardless of occupancy or need. Load managing devices are available that use
a passive infrared occupancy sensor to turn off the vending machine when the surrounding
area is unoccupied and turn it back on when the area is reoccupied. The load manager also
monitors the ambient temperature while the vending machine is off, and it powers up the
machine when required to ensure that the beverages stay cold. In addition, the load manager
monitors electrical current used by the vending machine so that it is not shut off while the
compressor is running to prevent a high head pressure start from occurring. This process
reduces maintenance costs and extends the life of the vending machine by significantly
reducing the number of compressor cycles. Typical energy savings have been documented to
be in the range of 35% - 45% of energy use. These controls have been deployed in several
areas to date; the remaining units (serving the Police Department and Senior Center) should
also be controlled.
5.5 WATER CONSERVATION
California is in its third year of serious drought. The Governor has declared a statewide
emergency due to water shortages and economic impacts. Given these circumstances, a
responsible Energy Efficiency and Conservation Strategy should address potential water
savings opportunities.
City of Tustin Energy Efficiency Conservation Strategy 22 1l12I2010
The City of Tustin has deployed (and will deploy more units in early 2010) low flow toilets and
urinals (including waterless fixtures) throughout the buildings included in this study. The City
standard for these fixtures include 1.5 gallon per flush (gpf) toilets and waterless urinals (0 gpf).
The impact of these changes is included in the EECS forecasts.
In addition to these changes, water usage may be reduced at the restroom faucets. These
units were observed to presently use aerators rated for flows of 2.0 - 2.2 gpm flows. These
aerators may be easily replaced (without changing the entire faucet) with 0.5 gpm units that still
provide adequate flow and pressure to rinse hands.
In addition to the capital projects outlined above, consideration should be given to the ongoing
maintenance of the irrigation systems serving the landscaping around the buildings. Damaged
sprinkler heads and mis-programmed controllers can also result in excessive water use by
these systems, often with no benefit as the surplus water is runoff to drain.
Water Wise Consulting, Inc has provided a report (not included within this document) that
provides fixture inventories and analysis for several City buildings, including the Civic Center,
and CT Gym. The remaining buildings were surveyed as part of the audit activity to support this
strategic plan.
5.6 DESK HEATERS
While not included as part of the capital project forecast, the City should deploy a program to
eliminate the use of personal heaters throughout. These existing units use a combination of
convection and conduction in an inefficient matter and can pose a fire risk if left unattended.
Instead, personal radiant heating panels are available that provide comfort and consume a
tenth of the energy. As an illustration, Project 21 includes the savings potential from the
replacement of 10 of such units.
City of Tustin Energy Efficiency Conservation Strategy 23 1 /12/2010
6. PERMIT FEE REBATE PROGRAM
To encourage awareness and energy efficiency throughout the City, the Tustin Energy
Efficiency Building Permit Fee Rebate Program will be developed in cooperation with the
Community Development Department to help offset plan check fees, permit fees and
inspection costs related to qualified improvements for:
• New solar panels or photovoltaic system Installation (avg. $550 each permit)
• New tankless water heating system Installation (avg. $50 each permit)
• Energy efficient air conditioning and ventilation systems upgrade -over the counter
permit -one inspection (avg. $50 each permit)
• Energy efficient furnace upgrade -over the counter permit -one inspection (avg. $50
each permit)
These fees will be reimbursed to the homeowner at the completion of the qualified project.
Recheck of plans, re-inspections, overtime inspections, and other fees not customary to
common plan check, research or inspections are not waived.
While this public outreach plan does not directly affect the energy consumption or carbon
footprint associated with the City buildings, it does incentivize the community to consider
energy efficient alternatives when performing upgrades or replacements to their property.

7.2 CARBON FOOTPRINT
The Carbon Footprint is the carbon consumption impact of an organization. It represents the
total amount of greenhouse gas (GHG) produced to directly and indirectly support the
organization's activities. A complete and comprehensive organizational CF includes three
types of emissions:
• Direct Emissions -From on-site consumption of energy, such as boilers, space
conditioning systems, furnaces, owned vehicles and equipment, etc.
• Indirect Purchased Electricity Emissions -Purchased electricity consumed at the
facility.
• Indirect Operational Emissions -Caused or influenced as a consequence of the
activities of the organization. These may occur from sources not owned or controlled
by the organization. Examples include faculty, staff and student commuting, air
transportation, research, production, purchasing, waste streams, contractor-owned
vehicles, outsourced activities and events.
City of Tustin Enerov Efficiency Conservation Strateov 25 1/12/2010
According to the international standard Green House Gas Protocol, the hierarchy for reporting
and taking action on GHG emissions is to:
• Measure and report climate-impacting emissions
• Reduce or eliminate GHG emissions by reducing or eliminating carbon consumption
• Replace, if possible, fossil fuel energy sources with renewable energy sources
• Neutralize unavoidable GHG emissions
Source Energv Carbon Footprint
As mentioned above, a complete carbon footprint would include all activities, such as
employees driving to and from work (some may take the less carbon intensive public
transportation), the amount and type of fuel used by vehicles and lawn equipment, the amount
of solid waste sent to landfills, etc. For this assessment, only the total annual electricity and
natural gas consumption is utilized to develop a Source Energy Carbon Footprint, the quantity
of carbon that was generated to produce and deliver the energy from all sources used by the
City buildings in a year.
The values used to calculate the Ibs C02 per kWh are different for each state and depend in
large measure on the electrical generation mix in that state (e.g. coal, nuclear, natural gas,
hydro, waste to energy, etc.).
• Based on the EPA's eGrid tables, the average California electric delivery is equal to
700.4 Ibs C02/mWh.
• The (Department of Energy's) Energy Information Agency stipulates a conversion of
121 Ibs C02/therm for natural gas.
The table below identifies the Source Energy Carbon Footprint reductions for the ECMs
recommended in this strategic plan.

Description:
Objective:
duce energy consumption associated with the building lighting by replacing existing 32 W (T8) lamps with fifth generation 25 W and 28
lamps. Ballast replacements are not necessary. Replace all non-dimmable incandescents with CFLs. Additionally, convert all/remaining

Project Name: I Lighting Retrofits I Internal Budget ID:I
Location : Senior Center System : Lighting Budget Affected : Utilities
Description:
Objective:
Reduce energy consumption associated with the building lighting by replacing existing 32 W (T8) lamps with fifth generation 25 W and 28
W lamps. Ballast replacements are not necessary. Replace all non-dimmable incandescents with CFIs. Additionally, convert all/remaining
exit signs to LED illumination. Finally, evaluate all outdoor lighting for LED or induction applications. This can be accomplished by means o
a group relamping or phased in as existing lamp inventory burns out.
Rationale:
Next generation lighting such as reduced-wattage T8 Lamps are designed to replace the old 34W/T12 lamps in fluorescent luminaire
retrofits where standard 32 W/T8 lamps would provide more light than is needed. They are available in 25 W and 28 W models and, in a
majority of the cases, can replace the original 32 W lamps without noticeable effect. Advantages include 24% lower energy consumption
and longer life.

The existing outside air dampers use dry bulb economizers that are not fully operational for most units. This results in wasted energy as
more unconditioned outdoor air is brought in than is required. The existing programmable thermostats do not provide the ability to

Project Description:
Objective:
Provide DDC based controls for all HVAC equipment to allow for optimal scheduling and set point configurations. Recommission the
outside air dampers and add C02 controls to optimize the economizer operations. Replace existing inlet guide vane operations with
variable speed drive control.
Rationale:
The existing outside air dampers use dry bulb economizers that are not fully operational for most units. This results in wasted energy as
more unconditioned outdoor air is brought in than is required. While inlet guide vanes do vary the supply air flow and provide some
energy reduction, variable speed drives provide greater savings and less reliance on mechanical linkages that may fail. Finally, upgrades to
DDC will allow for optimal control, including dynamic scheduling and greater response to outdoor conditions.

City of Tustin, CA Project No.: P-19
Project Scoping Worksheet Date: 1/8/10 Rev: 1
Project Name: Water Conservation (Toilets, Urinals & Faucets) Internal Budget ID:
Location : Senior Center System : Water Budget Affected : Utilities
Objective:
Continue the city's practice of replacing toilets and urinals with low or no flow units. Additionally, convert all faucets to low flow (0.5
use by replacing the aerator (without replacing the entire fixture).
Rationale:
As water resource continue to become scarce, water conservation becomes more critical and economically viable. The City of Tustin has
experienced success with the installation on waterless urinal in other buildings. Additional savings can be achieved through reduced flow
faucets and toilets as well.
Preliminary Financial Impact:
Projected Cost $: 2,968 Energy Savings $: 514 Simple Payback: 5.8 Yrs

City of Tustin, CA Project No.: P-21
Project Scoping Worksheet Date: 1/8/10 Rev: 1
Objective:
Desk Heaters Replacement /Removal - 30 Units
Replace existing convective desk heaters with radiant heat panels.
Rationale:
The radiant heating panels draw less than 1/10th the current than that of their convective counterparts. Use of a radiant heat source
saves energy by heating the objects as opposed to the air itself, providing equivalent heat at a reduced operating cost.

9. ROOFING REPLACEMENT PLAN
Several City buildings have roofing systems that are at (or nearing) the end of their rated useful
life, resulting increased maintenance and water leaks. Garland Roofing has provided an
assessment and recommendations for several of the buildings addressed by this plan. A
summary is provided below; additional detail for each roof is located in Appendix C.

TOTAL 107 700 48 465 -346 $8 555 $1 584 000
Note that natural gas savings is represented as a negative number as the reduced heat gain
penalizes the heating function.
ENERGY STAR® labeled roof products can save money and greenhouse gasses by reducing
building HVAC energy use associated with removing solar heat gain. These "cool roofs" work
by reflecting more of the sun's energy back into the atmosphere, keeping the building cooler
and reducing HVAC operations.
Savings are developed from the ENERGY STAR roofing calculator (located at
http://www.roofcalc.com/default.aspx). The roofing calculator estimates annual energy savings
for typical building types with non-metallic-surfaced roofs using typical weather conditions.
These estimates were derived based on simulations run with the DOE-2.1 E model using
cooling and heating degree-days. Actual savings will differ based on building design, building
operation, cooling and heating equipment, and local weather.
Because these replacements are driven by end-of-life issues, they are not included in the
energy forecasting. However, the energy savings associated (albeit minor) with these projects
are provided for informational purposes.

APPENDIX C: ROOFING REPLACEMENT & REPAIR PLAN
City of Tustin Energy Efficiency Conservation Strategy 57 1/12/2010
City of Tustin !Facility Name: City Hall

Flat Square Footage: 20,000
Estimated Cost of Solution Chosen: $275,000.00 J
Recommended Action Year: Year 1: 2009
Solution:
Option 2 V Option 3
Expected Life: 30 Years Cost Estimate: 5275,000.00
This option would require tearing the roof off down to the deck. A red rosin paper is loose laid which is covered by a type II base sheet.
This is nailed according to FM regulations. Then, two plies of Type IV plies are mopped in type III asphalt, shingle fashion directly to the
insulation. The two ply is covered with one ply of a high performance modified asphalt smooth sheet. The angles, projectings, and critical
areas will receive an extra ply of protection. Then the entire system will be covered with a mineral surface cap sheet.
The quality of the angles, which will get the majority of the abuse, varies widely from each manufacturer. Most modifieds will be affected by
sun. When a mineral surfaced modified membrane is used, that mineral surface is intended to provide UV protection although it is nominal.
recommend a UV resistant compound such as one that incorporates SBS, SIS and ES rubbers in the compound. These materials work
together as they age to keep the membrane soft and flexible. SBS, which is the common polymer in the generic modified sheets hardens as
it ages and the material becomes brittle. SIS softens in the same way old Scotch tape softens and turns to goo as it ages .These two
materials blended together significantly improves the long term weathering characteristics of the membrane by providing outstanding UV and
heat aging resistance. The ES polymer gives the membrane a harder surface. All of these attributes extend the life of the roof and reduce life
cycle costs. This will also include installing a title 24 coating.
Reinforcement is also important. This membrane should have some fiberglass scrim to provide dimensional stability and shrink resistance .
Most of the generic materials use a less expensive polyester which tends to allow for significant movement, which fatigues the polymer.
Polyester shrinks which puts a sheer stress on the seams. It is heat sensitive so it is often distorted during application. Fiberglass is
dimensionally stable, will not shrink, has excellent heat resistance and provides extremely high tensile strength. Polyester does provide tear
strength which is why it is put in with the fiberglass to make up the composite scrim reinforcement in the membrane .
There is no charge for the daily inspections or the warranty. These are done to make sure that this roof lasts, which is in everyone best
interest. Weekly reports will be provided to the City of Tustin.
This roof comes with a 30 year warranty.
Expected Life is an average, assuming that a proper evaluation 8 maintenance program is performed on a yearly basis.

it ages and the material becomes brittle. SIS softens in the same way old Scotch tape softens and turns to goo as it ages .These two
materials blended together significantly improves the long term weathering characteristics of the membrane by providing outstanding UV and
heat aging resistance. The ES polymer gives the membrane a harder surface. All of these attributes extend the life of the roof and reduce life
cycle costs. This will also include installing a title 24 coating.
Reinforcement is also important. This membrane should have some fiberglass scrim to provide dimensional stability and shrink resistance.
Most of the generic materials use a less expensive polyester which tends to allow for significant movement, which fatigues the polymer.
Polyester shrinks which puts a sheer stress on the seams. It is heat sensitive so it is often distorted during application. Fiberglass is
dimensionally stable, will not shrink, has excellent heat resistance and provides extremely high tensile strength. Polyester does provide tear
strength which is why it is put in with the fiberglass to make up the composite scrim reinforcement in the membrane .
There is no charge for the daily inspections or the warranty. These are done to make sure that this roof lasts, which is in everyone best
interest. Weekly reports will be provided to the City of Tustin.
These roofs come with a 30 year warranty.

This option would require tearing the roof off down to the deck. A red rosin paper is loose laid which is covered by a type II base sheet.
This is nailed according to FM regulations. Then, two plies of Type IV plies are mopped in type III asphalt, shingle fashion directly to the
insulation. The two ply is covered with one ply of a high performance modified asphalt smooth sheet. The angles, projectings, and critical
areas will receive an extra ply of protection. Then the entire system will be covered with a mineral surface cap sheet.
The quality of the angles, which will get the majority of the abuse, varies widely from each manufacturer. Most modifieds will be affected by
sun. When a mineral surfaced modified membrane is used, that mineral surface is intended to provide UV protection although it is nominal. I
