EXECUTIVE SUMMARY 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 (EEGs). The City of Tustin has been awarded an allocation of $677,300, in Energy Efficiency and Conservation Block Grant (EECBG) funds. To qualify for the release of the funds, the City has engaged IMPACT Industrial Services to assess the targeted buildings and develop the EECS. The five City facilities that were initially identified, inventoried and evaluated to reduce total energy use and improve energy efficiency include the 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 and included 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 EECBG grant funding: 1. Photovoltaic Installation at Columbus Tustin Gymnasium (CT Gym) 2. Tustin Energy Efficiency Building Permit Fee Rebate Program The current utility spends for these buildings have been calculated to be $368,000 annually, including electricity, natural gas, and water. The projects identified as part of effort can reduce this annual expenditure by 17%. A summary of all projects is presented below. Additional detail on the makeup of the utility consumption and the identified project savings (including carbon footprint) are provided within this document.

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.

Building specific ECM Scoping Worksheets are provided in Section 8 of this report. 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.

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. City of Tustin Energy Efficiency Conservation Strategy 16 1 /12/2010 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.

City of Tustin Energy Efficiency Conservation Strategy 17 1/12/2010 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. Youth Center: Based on a run time of 12 hours per day for 250 days per year. • Senior Center: Based on a run time of 11 hours per day for 250 days per year. • CT Gym: Based on a run time of 13 hours per day for 250 days per year and 7 hours per day for 104 days per year.

A more detailed lighting inventory for each building is provided in Appendix C. 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. „ r f ,M ~Y 6 s ~~ .~ k yt' ~° ,. ff ,,, ~ ~ if "' W \ ~ T ~ i Y:la'tF SliM4kF Q I5 !U ~ W r, en i i - e~ an !a n w T !. 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.

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.

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.

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.

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.

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 .
