Of particular note is the significant number of screw-in fixtures used to illuminate the roof dome and the theater. Both incandescent and CFL lamps are in used in these fixtures. Various lamp manufacturers were noted in the installed lamps throughout the site, and color temperature was varied due to inconsistent stocking and re-lamping. The interior lighting systems have been upgraded on an as needed basis. Interior lighting controls, such as occupancy sensors, are not utilized within the campus.

EXTERIOR LIGHTING Minimal exterior lighting is present at this site; exterior wallpack fixtures presumed to contain CFLs and two screw-in incandescent floodlight fixtures are located on the southeast side of the facility.

ENGINEERING AND TECHNICAL ANALYSIS

The following section contains the recommendations of CLEAResult on a measure by measure basis for your school. These recommendations are based on observations from the on-site energy audit as well as conversations with facility personnel before, during, and after the audit. These energy and cost savings estimates are meant to inform the school’s decision makers on the value and benefits of implementing energy efficiency measures. Final savings will be determined upon installation and/or commissioning systems and equipment upgrades. The recommendations include a summary table of energy and financial savings with annual cost savings and the Savings to Investment Ratio (SIR). Some of the basic assumptions that apply to all measures are listed below. The assumptions that the California Energy Commission (CEC) include in Proposition 39 analyses are listed as the CEC financial assumptions. There are some additional financial assumptions listed that apply to financial metrics beyond what the CEC may or may not consider in analyses. The blended utility rate used for energy cost is included for your school that is based on utility data collected.

CEC financial assumptions: . Inflation rate: 2.0% . Discount rate: 5.0% . Electricity escalation: 4.0% . Non-energy benefits: 5.0% . Maintenance savings: 2.0%

Additional financial assumptions: . Cost of capital: 10% . Capital recovery factor: 0.1315 . Estimated annual savings: Customers cost per unit of energy multiplied by total units of energy saved . Blended utility rate used for energy costs, $0.126/kWh and $1.00/therm . Estimated install cost: Estimated based on historical projects completed and/or industry standard pricing guides

It is important to note that some of the measures identified in this report may be eligible for rebates or incentives through PG&E’s School Energy Efficiency (SEE) program for which CLEAResult is the program implementer. Eligible measures under the SEE program must follow the procedures and requirements of that program as well as Proposition 39 procedures and requirements. It is noted in our recommendation where applicable energy efficiency measures fall under the SEE program.

The effective useful life (EUL) data is based on numbers provided by PG&E. Although they do not always match the Prop 39 guidelines, they are used as the basis of this report to calculate SIR and other financial measures. The EUL information used in the energy expenditure plan (EEP) use the EULs from the ¬Prop 39 guidelines document.

CALCULATION METHODOLOGY

During the inspection, the facility staff was interviewed to understand the typical schedules and maintenance practices. Documenting operational characteristics is vital in maintaining the embedded knowledge in the site. Typically, not all information related to operational history at the site is available through an on-site inspection. In order to gain visibility in this area, an interval data analysis is performed to better document how the site is operated. Whenever 15-minute electric data and daily gas data sets were made available by PG&E and the site, these documents are used to supplement assumptions. Energy usage and savings have been evaluated to reflect actual savings for projects whenever information was available. Standard engineering simulation techniques have been used that include direct calculations for lighting projects and calibrated simulations for HVAC measures. Weather correlations use data from the National Oceanic and Atmospheric Administration (NOAA) weather station located at the Fresno airport. Incentives and rebates for qualifying SEE measures have also been included within this report to provide your school with the best information to make decisions. Incentives and rebates change periodically based upon utility program cycles and adjusted baselines due to the newly adopted “Title 24” California energy code, so these results should be validated at the time of installation to ensure that they still apply. Installation costs have been estimated through various means. Lighting retrofit costs have been estimated based upon the average cost of similar project installations in California at schools (K-12). These costs represent a basic cost for the project. These costs can increase for many reasons that include the necessity to pay prevailing wage or scope creep potentially related to supplemental Title 24 requirements. Commissioning measures are dominated by time estimates for the expected work and use RS MEANS cost data to estimate labor cost.

ENERGY SAVINGS RECOMMENDATIONS

Based on surveyed conditions at the time of the on-site energy audit, as well as information collected from program staff, this report has developed recommendations for reducing energy use through school system retrofits. Recommendations are grouped by Facility End-Use, and include a description of the retrofit recommendation along with an economic analysis. The values provided are estimates and are derived by comparing baseline operating conditions and equipment in use documented through the audit process. This process is used to recommend operational and equipment upgrades that this audit has found to be viable energy saving retrofit option(s). These estimates are meant to help the school evaluate the relative value of implementing a system upgrade and make an informed purchasing decision that incorporates the benefits associated with energy efficiency. This report does not provide equipment or contract with the participant to install the recommended measures. It is up to the school to identify and secure a method of installation. CLEAResult can assist in evaluating contractor proposals and assist the school in securing a contractor to perform the work. It is critical for the school to inform the SEE Program that it is interested in a project before any action is taken. CLEAResult will continue to assist in evaluating any of the recommended retrofit projects as they develop, since changing the type and/or quantity of equipment purchased will impact the rebate or incentive associated with the project or projects. Failure to notify CLEAResult may cause a retrofit project to become ineligible for rebate or incentive.

IT/PLUG – PLUG LOAD OCCUPANCY SENSORS

Recommendation

This technology is optimal for any plug-in device which has no memory storage and only operates during occupied periods. A rebate amount of $15 per plug load occupancy sensor is available. Plug-in products can account for up to 15-20% of the energy consumed by commercial buildings and homes. According to the EPA, "energy consumption by office equipment represents the fastest growing use of electricity in the country." A plug-load occupancy sensor is a special power strip that powers the machines down when the room is unoccupied for periods up to ½ hour. This type of sensor is appropriate for items such as desk lamps, computer monitors, radios, personal heaters, and other non- essential electric loads. When the sensor detects occupancy, it turns on controlled outlets. When the space becomes vacant, the sensor turns off these outlets automatically after the preset time delay expires.

IT/PLUG – COMPUTER POWER MANAGEMENT SOFTWARE

Recommendation

Install Computer Power Management software to standardize power settings on all desktop computers connected to the school’s network as well as to schedule computers to shut down completely during the night. Additional features may include scheduled automatic software updates, visibility of current software licensing quantities, and timed sleep patterns. The cost of this product from certain vendors may be 100% covered by the rebate. . Computers on large networks are often set on various power saving settings. Individual computer settings can range from the maximum power saving setting to continuously on, often on workstations within the same lab. Computer Power Management Software can help ensure that every computer on the network is on the optimal power savings setting by centralizing control of the power settings at the server level. With a more centralized control, the IT staff is able to have control over all units in the network system, ensuring that computers are not running at night or on weekends and holidays and their power settings are not being overridden. When implemented over the entire network, this measure can lead to significant savings

LIGHTING – REPLACE INCANDESCENT/FLUORESCENT EXIT SIGNS

Recommendation

Replace any incandescent or CFL exit signs in your facility with LED exit signs. Emergency egress signs are one of the few electrical items in operation at a school 24 hours/365 days per year. Light Emitting Diodes (LEDs) provide bright, constant, and uniform illumination to the word "EXIT". LED Exit signs are also the most popular type of exit sign available today because of their combination of efficiency, longevity (8-10 years) and value. A typical LED exit sign will pay back itself in the form of energy savings within 3 years. Compared to traditional incandescent and fluorescent illuminated exit signs, LED exit signs are 10 times more efficient, drastically reducing electricity costs associated with exit signs. Incandescent exit signs typically consume 30-40 watts while LED models consume 2 to 4. Additionally, light source lifespan is expanded from 2,500 hours (incandescent) to 80,000 hours (LED), eliminating maintenance cost and time while improving reliability and building safety. Note: LED exit signs are no longer eligible for rebates but the measure is recommended as “low hanging fruit” that the school can easily do to achieve energy savings.

LIGHTING - REPLACE INTERIOR LIGHTING LAMPS/FIXTURES

T8 to LED Recommendation

LED troffer or panel fixtures represent the next step in advanced lighting design for interior spaces. Particularly in school districts, troffer and surface-mounted linear fluorescent fixtures are predominant in interior lighting systems. Options for upgrading these systems with higher efficiency linear fluorescent products is limited, but making the choice to install LED fixtures, tubes or retrofit kits will result in significantly more energy savings.

Aside from the tremendous energy benefits associated with installing high efficiency lighting, some additional advantages of LED technology include a much longer lifespan, consistent light output, wide selection of performance characteristics, and the ease of integrating controls.

Two options exist when eliminating linear fluorescent fixtures in favor of LED fixtures: LED retrofit kits and LED luminaire (fixture) replacements. Retrofit kits are ideal when the existing fixture housing is in good condition, fixtures are accessible, and the fixture spacing is appropriate for the new light source. A complete new LED fixture may be the best choice if the existing fixtures are in poor condition, new aesthetics are desired, or as part of a larger remodeling project.

Considerations for selecting an appropriate retrofit kit or fixture replacement include:

. Desired lighting properties: CRI, color temp, direct/indirect illumination . Existing luminaire condition and characteristics . Accessibility to the ceiling plenum

Due to differences in the light emitted from a fixture and the specialized nature of light emitted from an LED, it is advisable to think beyond a 1-for-1 retrofit strategy; depending on the needs of occupants and the room configuration, a reconfigured fixture layout may further optimize the lighting system. A lighting contractor should be consulted to arrange a room mock-up or test fixture before making a decision on large scale implementation of LED fixture replacement or retrofit. In most cases, a lighting system upgrade will trigger California Building Code (otherwise known as Title 24). To ensure compliance with Title 24, all mandatory measures pertaining to Altered Lighting Systems will need to be followed. For more information on lighting controls, please see Appendix C.

Currently, interior LED fixtures and retrofit kits qualify for a custom incentive from PG&E. It is recommended to replace T8 troffer and wraparound fixtures with LED troffer or surface-mount replacement fixtures or retrofit kits. Fixture counts can be reduced for the areas noted below, but a lighting vendor should be consulted before finalizing fixture count reduction plans:

Rebates are available for certain fixture types, including low- and high-bay, track, surface, pendant and recessed downlights. Fixtures or retrofit kits must be ENERGY STAR qualified, and must be on PG&E’s approved list at: http://www.lightingfacts.com/ca

We change the way people use energy™ School of Unlimited Learning Audit Report February 2015

Incandescent Lamp to Screw-in LED Lamp Recommendation

Also, screw-in LED replacements for incandescent lamps are available, which do not require any special retrofitting. Replace all screw-in incandescent or CFL lamps with new screw-in LED lamps. LEDs come at a slightly higher upfront cost when compared to incandescent and CFL lamps, but this can be easily recovered through energy savings and reduced lamp replacement costs over the lifetime of the bulb. The applications of LED technology should include simple bulb replacements on spot lighting, track lighting and recessed can fixtures when it is not practical to replace the entire fixture.

Please Note: PG&E does not provide rebates for replacing incandescent lamps with screw-in CFLs. Please refer to PG&E’s rebate catalog for more information on the lighting requirements: http://pge.com/mybusiness/energysavingsrebates/rebatesincentives/

HVAC CONTROLS – GLOBAL THERMOSTAT CONTROL Measure Description School districts often run into the issue of controlling all of their HVAC systems effectively. Manual thermostats provide the challenge of assuming that those that turn on the system also turn it off when they leave and that the set- points are at reasonable levels. 7-day programmable thermostats do not always shut down the units during school breaks and holidays and the clocks on those units do not always get adjusted for daylight savings time. Having a centralized HVAC controls system such as wireless thermostats that can be controlled through the internet or EMS systems that allow control through a central computer or software program can greatly optimize school’s HVAC system and minimize wasted energy. Items such as more closely limiting set-point temperatures, ensuring optimal start/stop times, and ensuring that the units do not get left on during nights/weekends/breaks/holidays can save the school, energy and reduce both energy costs as well as maintenance costs. Recommendation Install centralized controls for the HVAC units so that they can be controlled more closely. Ensure that temperature set points are controllable only to within a designated range. Ensure that the units do not run unnecessarily during nights, weekends, holidays, and breaks. Ensure that the programmed start and stop times are correct. Savings

Energy Calculations SOUL has some opportunities to reduce loads during the unoccupied periods. Through an analysis of 15-minute electric data, it appears that equipment is operating significantly during the night, over the weekend, during holidays, and over the summer when it is likely that the equipment does not need to be operating. Energy loads vary significantly throughout the night as equipment turns on and off, but there is also a weather correlation to this load which implies that part of this equipment is HVAC related.

Midnight Electricity Demand VS. Temperature (Shows energy usage at midnight due to temperature) Note that cooling also occurs during the unoccupied night.

During the period from November 2013 through October 2014, electric data set was available. The current electric baseline is 1.14 W/sf. It is assumed that the baseline can be brought down to a typical baseline of 0.45 W/sf. Loads above this point were totaled before 7 a.m. and after 8 p.m. Savings during weekends and holidays were only partially included, which could make these savings estimates conservative. Many other loads can contribute to this effect; these types of load could include pumps, fans, package units, pneumatic compressors, exhaust fans, refrigerated units or server/IT equipment. Uncontrolled appliances can continue to consume power unless they are turned off. Anything from printers, projectors, fax machines, VCRs, computers, etc. can contribute to this demand. Proper education and awareness campaigns about energy among school teachers and students can help save considerable energy. Unnecessary energy use can be contributed from heating, ventilation, and air conditioning (HVAC) equipment that may not be needed during unoccupied hours. CLEAResult recommends using a “night load” calculator to help identify what individual loads constitute this significant usage. We can provide this tool upon request.

HVAC CONTROLS – ENHANCED VENTILATION CONTROL Measure Description Enhanced Ventilation control consists of retrofitting an HVAC unit with variable speed motor control and the installation of demand control ventilation when it does not exist currently. Demand control ventilation (DCV) is achieved with a CO2 sensor and an advanced digital economizer control

(ADEC) system if not installed. A CO2 sensor is installed on the unit. The existing analog controller is replaced with a digital controller that is sensitive to small changes in the outside temperature. Thermostat wiring and operation is verified and adjusted for optimal usage of the economizer. The CO2 sensor and fan motor speed control is wired into the ADEC for integration of economizer and occupancy control. . The CO2 sensor allows the economizer to use less outside air during periods of reduced and low occupancy. . The ADEC is capable of detecting and reporting problems with sensors, dampers and other components so that the unit can operate optimally. . The ADEC adjusts the changeover setpoint with higher and lower humidity so the unit is not overburdened with a heavy latent load (lower changeover setpoint with high humidity and higher changeover setpoint with low humidity). . Variable speed fan motor control allows for additional energy savings by reducing air flow to meet demands with lower occupancy.

Recommendation Install variable speed motor controls and demand control ventilation on the large package units serving the Theater and the Rec Room. A permanent magnet or EC motor may replace the existing motor for additional energy savings; please see “Standard Efficiency Motor Replacement” in Appendix B for more details. This measure may be impacted by the 2013 Title 24 standards. Potential impacts are listed in Appendix D Building Energy Efficiency Standards (Title 24, Part 6) of this report for HVAC controls measures. This measure is eligible for rebate under PG&E’s business rebate program. Specific requirements must be met, and this measure cannot be combined with the advanced digital economizer controller or enhanced ventilation control rebate offers for the same HVAC unit. Variable air volume (VAV) units are excluded from this rebate.

HVAC – HEAT PUMP UNIT REPLACEMENT Description State of the art Heat Pumps (HP) are significantly more efficient than those available fifteen years ago. Older units require greater input energy levels to achieve the conditioning needs of the occupants, and the expense to operate and maintain these units over time increases. Problems often identified with heat pumps include: broken economizers, improper refrigerant charge, unoccupied period operation, fan/compressor short cycling, inadequate ventilation air, poor air flow, and dirty filters/coils. Existing heat pumps should be replaced when: . Existing heat pumps are more than 15 years old (with a proactive plan in place for units at the 10 year mark). . Existing heat pumps are in poor operating condition and require expensive repairs. . Improved humidity and comfort control of the building is required. . The building is undergoing a comprehensive retrofit. . Existing heat pumps use R22 refrigerant. Newer heat pumps contain components and technology designed to minimize energy usage, thereby enhancing cost-effectiveness and energy efficiency. When choosing a new heat pump, look for higher efficiency units and compare their incremental cost with their additional benefits: . High efficiency systems use less energy, which translates to less money spent on energy bills. . By using less energy high efficiency systems reduce the negative environmental effects of burning fossil fuels and greenhouse gas emissions. . Depending upon the space served, new units may include demand control ventilation, ensuring required ventilation is met without over ventilating the space. . Humidity – High efficiency systems not only help keep the air at the preferred temperature, but can more effectively remove moisture from the air. Modulated systems run longer cycles at lower pressures, helping to cool the air comfortably. Air that cools too fast without proper moisture removal can lead to mold and other airborne problems - See more at: http://www.ac- heatingconnect.com/seer-101/#sthash.gGzQU3NW.dpuf Proper sizing and installation can have a significant impact on HVAC equipment efficiency; ensure replacement units are properly sized and installed. An HVAC technician can perform load calculations to determine appropriate equipment sizing for your location. Equipment resizing can reduce energy usage by as much as 35 percent, according to the CEE. In order to properly size a system, it must be checked for duct leakage and other inefficiencies that adversely affect performance. Recommendation When choosing a new heat pump (HP), look for efficiency ratings in the following ranges: . Split HP units under 5.42 tons: 12.0 to 12.5 EER . Single package HP units under 5.42 tons: 11.6 to 12.0 EER . Wall mount heat pump units: 11.4 EER . 5.42 to <20 ton units: 11.5 to 12.2 EER . 20 ton units and larger: 10.3 to 10.8 EER

During school days, as the staff rooms become occupied earlier and become unoccupied later than theater. The two big YORK split units must run unnecessarily for just supplying the cooling load to those two staff rooms. Therefore, we recommend splitting this zone by adding two smaller split systems for these two staff rooms to avoid running the bigger YORK split systems when the theater is unoccupied and these two staff rooms are occupied. The following savings table took into account the addition of two small split systems with 2.5 tons of refrigeration capacity each for the counseling and student service office.

HVAC – PACKAGE UNIT REPLACEMENT

Description State of the art single zone, constant volume, packaged rooftop units (RTUs) are significantly more efficient than those available fifteen years ago. Older units require greater input energy levels to achieve the conditioning needs of the occupants, and the expense to operate and maintain these units over time increases. Problems often identified with RTUs include: broken economizers, improper refrigerant charge, unoccupied period operation, fan/compressor short cycling, inadequate ventilation air, poor air flow, and dirty filters/coils. Existing RTUs should be replaced when: . Existing RTUs are 15 years old (with a proactive plan in place for units at the 10 year mark). . Existing RTUs are in poor operating condition and require expensive repairs. . Improved humidity and comfort control of the building is required. . The building is undergoing a comprehensive retrofit. . Existing RTUs use R22 refrigerant. Newer package units contain components and technology designed to minimize energy usage, thereby enhancing cost-effectiveness and energy efficiency. Higher efficiency units do cost incrementally more. However, more efficient units have additional benefits: . High efficiency systems use less energy, which translates to less money spent on energy bills. . By using less energy high efficiency systems reduce the negative environmental effects of burning fossil fuels and greenhouse gas emissions. . Depending upon the space served, new units may include demand control ventilation, ensuring required ventilation is met without over ventilating the space. . Humidity – High efficiency systems not only help keep the air at the preferred temperature, but can more effectively remove moisture from the air. Modulated systems run longer cycles at lower pressures, helping to cool the air comfortably. Air that cools too fast without proper moisture removal can lead to mold and other airborne problems - See more at: http://www.ac- heatingconnect.com/seer-101/#sthash.gGzQU3NW.dpuf Proper sizing and installation can have a significant impact on HVAC equipment efficiency; ensure replacement units are properly sized and installed. An HVAC technician can perform load calculations to determine appropriate equipment sizing for your location. Equipment resizing can reduce energy usage by as much as 35 percent, according to the CEE. In order to properly size a system, it must be checked for duct leakage and other inefficiencies that adversely affect performance. Recommendation When choosing a new RTU, look for efficiency ratings in the ranges of 14.0 to 16.5 SEER for small units (>5.42 tons) 11.5 to 12.0 EER for medium sized and large units (5.42 to 63.33 tons) and 9.7 to 10.2 EER for even larger units (>63.33 tons).

HVAC – DUCT SEALING

Recommendation

Using ducting to convey heated air to warm classrooms and offices requires well-sealed and insulated ductwork in order to warm the space efficiently and maintain good indoor air quality. Leak, holes, and poorly connected ducts can lead to significant loss of air as it travels to the room, and forces the heating unit to operate longer to achieve the desired room temperature. Ducting should be mechanically fastened and sealed tightly with mastic and/or Underwriters Laboratory (UL) 181B-FX approved tapes, such as metal backed tape, according to the EPA. “Duct tape” is not recommended. Ductwork should also be enclosed inside the building envelope, since the air distribution system works most efficiently in conditioned air at room temperature, as opposed to un-insulated attics and crawlspaces. If it is not practical or possible to enclose the ducting inside, ducts should be insulated as recommended by the International Energy Conservation Code (IECC) and California’s Title 24.

ENVELOPE – COOL ROOF AND INSULATION

Recommendation

Typically, re-roofing is expensive compared to the energy savings that can be achieved. However, the additional cost to install a more energy efficiency roof is minimal (based upon DOE studies). This recommendation suggests in the event that the roof needs to be replaced, the school should consider installing a Cool Roof in addition to improving roofing insulation beyond the code requirement of R14. By upgrading to this reflective barrier, known as a CoolRoof, solar gain through the roof is decreased. This change has the benefit of reducing heating loads during the cooling seasons. However, it should be noted that there will be a heating penalty during the heating season because solar gains are again reduced. Un-insulated shell elements in the building can greatly influence the indoor air quality (IAQ) as well as the heating and cooling load of the building. The R-values (thermal resistance unit) of typical construction materials are very low and as a result, they do not provide much resistance to the heat loss during winter or heat gain in summer. Paybacks on insulating uninsulated buildings can vary depending upon the ease of installation and the existing conditions. However, paybacks on adding insulation to existing buildings are not as quick owing to a diminishing returns trend observed. A good way to overcome this would be to increase insulation to the recommended levels at the end of useful life of existing insulation in the shell elements or to act on these projects when areas are exposed for other reasons. Please Note: 2013 Title 24 regulations may require specific insulation values for certain climate zones and space types. Cool Roof specifications are required in California for re-roofing in Climate Zone 11 (Anderson, CA) to meet the following prescriptive requirement: - Aged reflectance: >=0.63 - Initial thermal emittance >=0.75 OR - Aged solar reflectance index >=75 Actual savings vary depending upon existing conditions and the orientation of the building. These vary up to 25% of the cooling load when no existing insulation is present. This is not the case at SOUL. Insulation generally exists, but has been compromised in some areas. An average savings has been estimated by performing multiple runs of the Cool Roof software module.

SOLAR – PHOTOVOLTAIC SYSTEM

Recommendation

It is recommended to select viable energy efficiency measures recommended in this report prior to installing a PV system. Proposition 39 guidelines have a few requirements that must be met in order for this measure to be installed when the financing is secured through a power purchase agreement (PPA). A PPA is an agreement between the vendor and the district for the vendor to install and maintain the equipment over the life of the contract with the district purchasing power provided by the equipment over the life of the contract. If the project is financed via PPA the district must include a letter of intent from a vendor with the energy expenditure plan that includes the following:

. Project or system size (capacity) . PPA term . PPA energy rate with any applicable rate escalations (not to exceed 3% escalation) . Anticipated rebate or incentive amount . Estimated production (kWh and kW) and cost savings over the PPA term . Demonstrate above savings meet required SIR

The PPA must be accompanied by a performance guarantee of 95% estimated production over 5 years, and additional performance and production guarantee over the life of the PPA term. If productions fall below the guaranteed threshold, the vendor must reimburse or compensate the district for the shortfall.

A few advantages on solar installation projects that schools benefit are listed below:

 Unused space in the schools locations, such as roofs and parking lots, provide electricity to the electric load of the building while use the utility grid as a back-up power source.  PV Applications for parking lots (carports) have a nice impact, not only in renewable energy production, but also by mitigating the extreme temperatures of direct sunlight on the car.  The State of California has net-metering laws, which means that on a grid-connected PV, power sent to the grid is credited to the system owner at the same retail rate a utility customer would be paying for power generated by the utility, if no net excess energy is generated by the end of the month.  PV peak production period usually matches the peak demand period, which has an effect on bigger economic savings at the end of the billing period.

APPENDICES

APPENDIX A – NO COST / LOW COST ACTIONS

CLEAN LIGHT FIXTURE LENSES Description

Lenses on exterior fixtures serve many purposes - they protect the lamp, keep the interior of the fixture clear of debris and modify or direct the light emitted from the lamp. Over time, the lenses become discolored and yellow due to interactions between dust, heat, and ultraviolet light. All exposed surfaces of the fixture will accumulate dirt unless cleaned. Between these conditions, usable light output can diminish by more than 20%. Recommended Action

Keep exterior fixture lenses clean. Cleaning a dirty lens can increase light output by 10%. Alternatively, replacement lenses made of acrylic can transmit approximately 92% of a fixture's light.

HVAC EQUIPMENT LABELS Description

Labeling of HVAC components is an inexpensive and effective method for helping facilities personnel properly operate and maintain the HVAC systems. The labels should be easy to read when standing next to the equipment, and durable to match the life of the equipment to which they are attached. "AHU" refers to any air handling unit that is associated with outdoor air supply. Recommended Action

At a minimum, the following components should be labeled in each ventilation zone of the school and should correspond with the HVAC diagrams and drawings: . The number or name of the AHU (e.g., AHU ##, or AHU for West Wing) . The outdoor air (OA), supply air (SA), return air (RA), and exhaust or relief air (EA) connections to the AHU, each with arrows noting proper airflow direction . The access door(s) for the air filters and the minimum filter dust-spot (or MERV) efficiency (Air Filters, minimum xx% dust spot efficiency) . The filter pressure gauge and the recommended filter change pressure (Filter Pressure, max 0.x in. w.g.) . The access door(s) for the condensate drain pan (Drain Pan) . Other pertinent access doors such as to energy recovery ventilation wheels or plates (Energy Recovery Ventilation Unit) . The minimum amount of outdoor air for each AHU (### CFM minimum during occupied times) . The outdoor air damper (OA Damper), with special marks noting when the damper is in the fully closed (Closed), fully opened (Open), and minimum designed position (Min) . If a motorized relief damper is installed (EA Damper), note the same positions as above.

We change the way people use energy™ School of Unlimited Learning Audit Report February 2015

. The access door to any outdoor air controls (OA Control(s)) such as damper position adjustments, outdoor airflow measuring stations, resets, fuses, and switches) . Breakers for exhaust fans (Exhaust Fan ##), AHU, unit ventilators . Access doors for inspection and maintenance of air ducts . Any dampers and controls for air side economizers (as appropriate) . The number or name of all exhaust fans, including the air quantity exhausted (EF##, ###CFM)

SERVER CLOSET THERMAL ENVIRONMENT RESET Description

Reset server closet temperature. The supply temperature to the server areas can often be raised above traditional settings without affecting the thermal equipment environment. Use environmental specifications provided by ASHRAE or NEBS to target appropriate temperatures within the range of 59°F - 90°F. Recommended Action

Reset server closet temperatures to a higher setting. Energy savings of about 1% per degree F rise in temperature can be realized.

WALL-SWITCH TIMERS Description

Wall-switch timers come in different forms. Some allow for pre-programming of a certain length of time that the lights are turned on for each time the button is pushed. Others are a simple twist timer that allows the occupant to set the length of time that they wish the lights to be on. In spaces that see

We change the way people use energy™ School of Unlimited Learning Audit Report February 2015 intermittent use, wall switch occupancy sensors are typically a good recommendation. However, for spaces that are larger and cannot be covered by a wall-switch sensor alone, a wall-switch timer is a good alternative to ensure that the lights eventually turn off once people leave the room. Recommended Action

This technology is optimal for areas that are too large for a standard wall-switch occupancy sensor to use and have intermittent short usage such as break rooms, work areas, or teachers’ lounges where the more expensive ceiling mounted occupancy sensors are not required.

We change the way people use energy™ School of Unlimited Learning Audit Report February 2015

APPENDIX B – SUGGESTED MEASURES

STANDARD EFFICIENCY MOTOR REPLACEMENT Description

The cost of electricity to operate a motor over its life time is much greater than the initial capital cost of the motor itself. Typical life time of a motor, according to motor manufacturers is about 40,000 hours. Therefore it is cost effective to invest in the purchase of the highest efficiency motor available because of the huge energy saving potential over the life time. It is recommended to replace old and worn out motors with premium efficiency motors rather than rewind because, according to US Department of Energy studies of motors and motor drives in manufacturing facilities, rewinding makes a motor about 2% less efficient every time. Other advantages of premium efficiency motors include cooler operation because of lower losses and higher power factor and longer lifetime because of heavier duty bearings found on them. Recommended Action

Replace old, worn out, or broken standard efficiency motors with the highest efficiency motor that is feasible.

OFFICE EQUIPMENT Description

Small appliances, such as mini fridges, microwaves, and coffeemakers, can proliferate in the school environment, leading to high plug loads. Each plugged-in appliance contributes somewhat to overall energy consumption at the site, sometimes referred to as “phantom loads” and can often represent an opportunity to lower the site’s energy demand baseline. Lots of references exist to address these types of issues. A good description of the issues is presented in this reference: http://energy.maryland.gov/incentives/schools/resources/presentations/workshop2/Plugloads.pdf

Furthermore, the Department of Energy (DOE) through the Federal Energy Management Program (FEMP) provides good guidance on identifying and addressing phantom loads within school facilities. These items are included: . TV 1 watt . VCR 2 watts . DVD Player 1 watt . Audio Product 1 watt . Desktop Computer 2 watts . Workstation 2 watts . Laptop Computer 1 watt . Copier 1 watt . Printer 1 watt

We change the way people use energy™ School of Unlimited Learning Audit Report February 2015

Recommended Action

Limit possession of personal appliances in classrooms and offices, if applicable. Education campaigns for the site population, including students, staff, and faculty, have been effective at raising awareness and reducing energy consumption attributed to personal appliances without compromising occupant comfort or convenience.

LOW FLOW DEVICES High Efficiency Toilets

Early models of low flow toilets gave little consideration to the design of the bowl and focused solely on reducing the amount of water used per flush. This led to problems with clogging and multiple flushes. The new generation of high efficiency toilets has not only improved flushing ability, but has further reduced the amount of water per flush. New toilets have flush rates as low as 1.0 gallons per flush (GPF), compared to the current federal standard of 1.6 GPF. Replacing first generation low-flow toilets not only saves money from reduced water use; it also improves toilet performance and reduces sewer costs. Faucet Aerators

Faucet aerators are a simple, inexpensive way to reduce water usage without decreasing faucet pressure. Aerators are small screened cylinders that screw onto your existing faucet. When the water flows through them, it is mixed with air from the gaps in the screen. This helps maintain a high, consistent water pressure without letting as much water through. Bathroom faucets without aerators use between two and four gallons of water per minute, while faucets with aerators typically use less than one gallon per minute.

HIGH EFFICIENCY KITCHEN EQUIPMENT Kitchen equipment at the end of its life, is optimal for replacement with an efficient model. Since kitchens which actively cook food represent a significant portion of energy costs, selecting energy efficient kitchen equipment is an effective way to reduce consumption. Water savings of 25% and energy savings of 25% are possible by upgrading from standard efficiency models. Three organizations provide mainstream efficiency standards, and guidelines for commercial foodservice equipment:  For ratings, please visit Energy Star's website, http://www.energystar.gov/.  For rebates, check out Foodservice Technology Center (FSTC), http://www.fishnick.com/.  Find further resouces at the Consortium for Energy Efficiency (CEE), http://www.cee1.org/.

We change the way people use energy™ School of Unlimited Learning Audit Report February 2015

Recommended Action

Develop an energy efficient equipment replacement plan to take advantage of equipment failure. Consider replacing equipment which is more than 10 years old. Check out www.fishnick.com for current information about rebates available for kitchen equipment of all types.

AIR CARE PLUS AirCare Plus tune-up services offer a thorough inspection and adjustment for unparalleled performance. Even if the HVAC unit receives standard routine maintenance, a certified AirCare Plus technician can identify new opportunities to increase your system’s operational efficiency including:  Programmable Thermostats - Install and set a schedule Your certified AirCare Plus contractor will install and program a qualifying programmable thermostat for optimal system run time (if eligible). A programmable thermostat gives you the ability to set a heating/cooling schedule based on actual building occupancy, rather than conditioning the air 24-7-365.  Economizer - Repair, replace sensor, and optimize adjustments Your HVAC’s economizer saves energy by ensuring your building is making the best use of free, fresh outdoor air, rather than relying completely on the HVAC system to cool the space with conditioned air. If your HVAC’s economizer is not operational, your contractor can repair it to restore functionality. Typical repairs include the replacement of CO2 sensors, repairing damaged wiring, or replacing broken mechanical components such as motors or actuator.  Refrigerant Charge - Adjust and test Your unit is tested to determine if it has the proper amount of refrigerant. If the charge needs adjustment, your contractor will adjust the charge and re-test the charge to verify the success of the repair.  Airflow - Clean coils and install cogged v-belts Cleaning evaporator and condenser coils ensures optimal heat transfer, resulting in decreased run times, energy savings, and an overall reduction of energy demand. Cogged v-belts run with less mechanical resistance than smooth blower belts, increasing efficiency, saving energy, and prolonging the life of your equipment. The AirCare Plus Program is designed to enhance existing HVAC maintenance. The following are eligibility requirements to participate in the AirCare Plus Program:  Commercial electric customers of PG&E  Packaged HVAC or qualifying split systems

APPENDIX C – LIGHTING CONTROLS: SENSOR APPLICATIONS

INTERIOR CONTROLS Interior fixtures can be left on for significant periods during the day due to a number of reasons. To limit this unnecessary operation all new interior fixtures should be specified with sensors. Daylight sensors will detect when the natural light levels are sufficient to adjust the level of artificial light in the room and vacancy sensors will ensure that the fixture is turned off during the unoccupied times. By installing a time clock concurrently with the sensors, the lights can be shut down during non-business hours. The three sensor technologies listed here are potentially required by Title 24 in retrofit situations. Sensor installations can be on each fixture individually or included at a site level through an EMS control strategy. Actual savings may vary depending on the operation of the associated fixture. Information regarding exterior sensors can be found in the “Lighting Controls – Exterior Sensors” section of this Appendix. Daylighting: A daylight harvesting system has the potential to reduce interior lighting energy use while the space is occupied. As the daylight sensor reacts to light levels, the light emitted from each fixture is adjusted accordingly to apply a uniform, consistent light level across the space. Aside from energy- saving benefits, studies have shown a positive effect on human health and productivity by using light from the sun in classrooms (Daylighting Pattern Book, Lighting Research Center, 2010). Daylighting controls are now required in many spaces by Title 24. Dimming: Provides the ability to decrease lighting levels in the room from full brightness down to 10% brightness. Allows the light in the room to be tailored to a specific activity: full bright for lab time and dimmed down for smartboard or projector based lessons. Title 24 code specifies how many “steps” or levels of dimming are required for a particular space type. Vacancy: Two types of sensing mechanisms are available with occupancy/vacancy sensors: Passive Infrared (PIR), which detects large motions, and Ultrasonic, which can detect smaller motions. Use sensors that employ both technologies, called Dual Technology Sensors, in order to limit the occurrence of false-offs. These sensors are especially effective if teachers leave the lights on during class breaks and if lights are left on in the classrooms until the night custodians leave. Title 24 now requires occupancy-based lighting controls for most interior spaces.

 Fixture Integrated Occupancy Sensor

Install fixture integrated occupancy sensors on linear fluorescent high bay fixtures. If the lights will be frequently turned on and off, consider using program-start ballasts with the fixtures as well. One of the benefits of fluorescent high bay fixtures over HID fixtures is the instant re-strike time, which makes it possible to turn the lights on and off instantly. This allows those fixtures to work well with occupancy sensors. Purchase fluorescent high bay fixtures with an occupancy sensor integrated directly into the fixture. Each fixture will then be controlled with an occupancy sensors, so when only half of the gym is being used, the lights on the other end can be shut off. These sensors can be modified to fit a particular space (i.e. an aisle or gymnasium) by changing the sensitivity as

We change the way people use energy™ School of Unlimited Learning Audit Report February 2015

well as the amount of buffer time to leave the lights on when no activity is detected. When used in conjunction with T8 and T5 lamps, Program-Start ballasts can help prolong the lamp life in areas where occupancy sensors would be used.

 Wall-Mounted Occupancy Sensor

Install wall-switch occupancy sensors in private offices and other small spaces where automated light switches will save energy. Wall-switch occupancy sensors are relatively inexpensive and easy to install because they can replace a normal wall switch without special wiring. They are ideally suited for small spaces such as individual offices, closets, or personal restrooms. Make sure the sensor has a clear view to all areas for proper operation and can cover the space required.

 Ceiling-Mounted Occupancy Sensor

Install ceiling mounted occupancy sensors in larger spaces such as classrooms where automated lighting controls will save energy. Ceiling mounted occupancy sensors are most effective in large, open areas where their high position reduces the likelihood furniture, like TV stands or book cases, will block the sensor's view. Two types of sensing mechanisms are available with these occupancy sensors: Passive Infrared (PIR), which detects large motions, and Ultrasonic, which can detect smaller motions. Use sensors that employ both technologies, called Dual Technology Sensors, for classrooms or study areas in order to limit the occurrence of “false-offs”. These sensors are especially effective if teachers leave the lights on during class breaks and if lights are left on in the classrooms until the night custodians leave.

Timeclock: Installing time-of-day controls in addition to the sensor type listed above will allow the lighting system to be turned on only within specified operating hours. Shut-off controls are required by Title 24. Please Note: No rebates for interior controls are generally available after June 30, 2014 due to changes in Title 24, CA Building Codes and Standards.

EXTERIOR CONTROLS Exterior fixtures can be accidently left on during the day due to a number of reasons. To avoid this occurrence all new exterior fixtures should be specified with photocell sensors. Photocell sensors will detect when the sun rises and sets and will ensure that the fixture is turned off during the day. In many cases, even with photocells, the fixture may be located in a shaded spot or the photocell eye is dirty and the light stays on even during the daytime. By installing a time clock concurrently with the photocells, the lights can be shut down during the daylight hours even though the photocell may detect

The three sensor technologies listed here are required by Title 24 in most retrofit situations. Sensor installations can be on each fixture individually or included at a site level through an EMS control strategy. Actual savings may vary depending on the operation of the associated fixture. Information regarding interior sensors can be found in the “Lighting Controls – Interior Sensors” section of this Appendix. Photocell: Exterior fixtures can be accidently left on during the day due to a number of reasons. To avoid this occurrence all new exterior fixtures should be specified with photocell sensors. Photocell sensors will detect when the sun rises and sets and will ensure that the fixture is turned off during the day. Photocells are required by Title 24. Occupancy: Required by Title 24 for mounting heights under 24-ft, an occupancy sensor will turn the fixture on to full brightness when the sensor detects movement, heat, or both, depending on the type of sensor. Timeclock: In many cases, even with photocells, the fixture may be located in a shaded spot or the photocell eye is dirty and the light stays on even during the daytime. By installing a time clock concurrently with the photocells, the exterior lights can be shut down during the daylight hours even though the photocell may detect that the area appears dark. Time-based controls are required by Title 24.

APPENDIX H – DEFINITIONS

FINANCIAL DEFINITIONS Future Value

Future-Value cash flows are the estimated annual energy savings in dollars spread over the life of an investment. Discount Rate

Discount-Rate is the minimum rate of return required by a district. The Discount-Rate is used as the interest rate in Present-Value calculations. The Discount-Rate is used as a measure of risk, used to account for any variables or changes that may affect the economic value of the investment. The higher the perceived risk of an investment, the higher the Discount-Rate should be. The higher the Discount- Rate assigned to an investment, the lower the Present-Value of the investment will be Present-Value

Present-Value is the discounted sum of all Future-Value cash over the life of an investment. Using a Discount-Rate, the district discounts the Future-Value cash flows of the investment based upon the perceived risk the investment poses to the organization. PV = FV Cash Flow/ (1+Discount-Rate)^Project Life

Net-Present-Value

Net-Present-Value is the Present Value of all future cash flows over the life of an investment minus the initial project cost. NPV= Sum(Present Value Cash Flows) – Investment Cost

Internal-Rate-of-Return

Internal-Rate-Of-Return is an internal financial metric used by districts to decide whether or not to undertake an investment. The higher an investments Internal-Rate-Of-Return, the more desirable it is to undertake. Assuming all investments require the same upfront cost, the investment with the highest IRR would be considered the best and undertaken first. The basic rule is that if an investment produces an Internal-Rate-Of-Return greater than the investment’s Discount-Rate, the investment is economically feasible. If the Internal-Rate-Of-Return is less than the investment’s Discount-Rate, the investment should not be undertaken. Modified Internal-Rate-of-Return

Modified-Internal-Rate-Of-Return is an internal financial metric used by districts to decide whether or not to undertake an investment. Similar to Internal-Rate-Of-Return, a Modified-Internal-Rate-Of-Return greater than the investor’s Discount-Rate would indicate that the investment should be undertaken. Modified-Internal-Rate-Of-Return has an advantage in that it assumes cash flows from the investment are re-invested at a “safe-rate”. The “safe-rate” in the context of energy efficiency is the required rate of return for an investment, typically equal to the Discount-Rate.

Simple Payback Period

Compared to the more sophisticated financial measures such as Net-Present-Value and Modified- Internal Rate-Of-Return, Simple Payback is simple to understand. Its simplicity however can cause districts to overlook potentially very profitable investments. Simple Payback is calculated as the number of years it takes for an investment to “pay for itself” through the annualized savings or benefits that the investment creates. The major drawback of using Simple Payback as a decision making tool is that it measures only time, and does not take in to account the cost of money or the profitability of an investment after the project has paid for itself. Capital Recovery Rate (j)

The interest rate used in the capital recovery factor formula. Typically most districts will use their Weighted Average Cost of Capital (WACC), adjusted up or down for perceived risk. Capital Recovery Factor

The Capital Recovery Factor (CRF) is used to determine a single annual cost incurred, spread out over the economic life of an investment. The purpose of using a CRF is to provide a district with a single cost to use when budgeting capital expenses, such as energy efficiency improvements. The Capital Recovery Factor takes into account the Discount Rate (j) used in the cash flow valuation of an investment and the economic life (n) of the investment to provide investors with a present value cost. The formula is shown below: Capital Recovery Factor (CRF) = [j(1+j)^n]/[(1+j)^n]-1

Annualized Project Cost

Annualized Project Cost is used in the Cost-of Delay financial model. This metric identifies all of the costs and benefits associated with an investment and amortizes them as a fixed amount that can be budgeted over the economic life of the equipment, similar to how home mortgage payments are determined. The Annualized Project Cost is determined by multiplying the project cost by the Capital- Recovery-Factor. Annual Cost-of-Delay

The Annual-Cost-of-Delay is the annual cost a district would incur by operating inefficient equipment compared to investing in an efficient upgrade. The equation is shown below: Annual-Cost-of-Delay = Annual Gross Energy Savings ($) – Annualized Project cost

Savings-to-Investment Ratio The Savings-to-Investment Ratio (SIR) is calculated based on the net present value, the project installation cost, and any benefits to the cost including rebates, grants, and non-energy benefits. Under Proposition 39 guidelines non-energy benefits are generally considered to be 5% of project costs. Bond funds can be considered grants when they are tax-backed bonds or non-general obligation bonds, for which a tax source repays the bonds. Additional fund sources can be used to finance projects, but will not “buy down” the cost of the project. The SIR equation is as follows: SIR = NPV / (Project Installation Cost – Rebates – Grants – Non-energy Benefits)
