AkWarm-C is a building energy modeling software developed under contract by AHFC. Limitations of Study This energy audit is intended to identify and recommend potential areas of energy savings, estimate the value of the savings, and provide an opinion of the costs to implement the recommendations. This audit meets the criteria of a Level 2 Investment Grade Audit (IGA) per the American Society of Heating, Refrigeration, Air-conditioning Engineers (ASHRAE) and the Association of Energy Engineers (AEE), and is valid for one year. The life of the IGA may be extended on a case-by-case basis, at the discretion of AHFC. In preparing this report, the preparers acted with the standard of care prevalent in this region for this type of work. All results are dependent on the quality of input data provided. Not all data could be verified and no destructive testing or investigations were undertaken. Some data may have been incomplete. This report is not intended to be a final design document. Any modifications or changes made to a building to realize the savings must be designed and implemented by licensed, experienced professionals in their fields. Lighting upgrades should undergo a thorough lighting analysis to assure that the upgrades will comply with State of Alaska Statutes as well as Illuminating Engineering Society (IES) recommendations. All liabilities for upgrades, including but not limited to safety, design, and performance are incumbent upon the professional(s) who prepare the design. Coffman Engineers, Inc (CEI) and Central Alaska Engineering Company (CAEC) bear no responsibility for work performed as a result of this report. Financial ratios may vary from those forecasted due to the uncertainty of the final installed design, configuration, equipment selected, installation costs, related additional work, or the operating schedules and maintenance provided by the owner. Furthermore, many ECMs are interactive, so implementation of one ECM may impact the performance of another ECM. CEI and CAEC accept no liability for financial loss due to ECMs that fail to meet the forecasted financial ratios. The economic analyses for the ECMs relating to lighting improvements are based solely on energy savings. Additional benefits may be realized in reduced maintenance cost, deferred maintenance, and improved lighting quality. The new generation lighting systems have significantly longer life leading to long term labor savings, especially in high areas like Gyms and exterior parking lots. Lighting upgrades displace re-lamping costs for any fixtures whose lamps would otherwise be nearing the end of their lifecycle. This reduces maintenance costs for 3-7 years after the upgrade. An overall improvement in lighting quality, quantified by numerous studies, improves the performance of students and workers in the built environment. New lighting systems can be designed to address all of the above benefits.

Introduction This energy audit was conducted at Palmer High School (PHS) for AHFC and Matanuska-Susitna Borough School District. The school is a 197,494 square foot (sf) campus that includes classrooms, locker rooms, restrooms, administrative offices, a library, a gymnasium, and a pool. The location of the school is shown in the following regional and overhead images. The energy audit was conducted in order to evaluate areas and equipment where energy savings can be realized. The savings are then compared to a baseline and evaluated for reasonable project financial ratios and payback.

Energy Audit Process Prior to visiting the school, the first task was to collect and review two years of utility data for electricity and natural gas usage. This information was used to analyze operational characteristics, calculate energy benchmarks for comparison to industry averages, estimate savings potential and establish a baseline to monitor the effectiveness of implemented energy conservation measures. A spreadsheet was used to enter, sum, and calculate benchmarks and to graph energy use information (see Appendix A). The primary benchmark calculation used for comparison and baseline data is the Energy Utilization Index, or EUI (see Section VI). After gathering the utility data and calculating the EUI, the next step in the audit process was to review the architectural and engineering drawings to develop a building profile which documented building age, type, usage, and major energy consuming equipment or systems such as lighting, Heating, Ventilating, and Air Conditioning (HVAC), water heating, refrigeration, snow-melt, and etc. The building profile is utilized to generate, and answer, all possible questions regarding the facility’s energy usage. These questions were then compared to the energy usage profiles developed during the utility data gathering step. After this information was gathered, the next step in the process was to conduct a site survey. A site survey was completed on January 03, 2012. The audit included inspecting the building systems that impact energy consumption and answering questions from the preliminary review of the school. The on- site contact during the investigation was Mr. Rick Jensen of the MSBSD Maintenance Department1. The following information was also collected while on site: occupancy schedules, O&M practices, building energy management program, and other information that has an impact on energy consumption. The following energy audit includes an evaluation of the information gathered, the researching of possible conservation opportunities, organizing the energy audit into a comprehensive report, and making ECM recommendations for mechanical, electrical, and building envelope improvements. 1 Mr. Rick Jensen, (907) 354-0348 (mobile), (907) 864-2007 (office) Palmer High School Final Energy Audit Report Coffman Engineers, Inc. 6/13/2012 6 AkWarm No. CIRI-PAQ-CAEC-03 IV. Method of Analysis Having completed the preliminary energy audit tasks, Coffman Engineers, Inc., (CEI) conducted a site survey. The site survey provides critical input in deciphering where energy savings opportunities exist within a facility. The audit team from CEI walked the entire site to inventory and investigate the building envelope and major equipment, including: HVAC, water heating, lighting, and equipment located in shops, kitchens, offices, and classrooms. An understanding of how the equipment is used is determined during the site survey. The collected data was entered into AkWarm Commercial™ software, an energy calculating program for buildings. The data was processed by AkWarm to model a baseline from which ECMs could be considered. The model was compared to actual utility costs to ensure the quality of the baseline and proposed energy modeling performed by AkWarm. The recommended ECMs focus on the building envelope, HVAC, lighting, water heating, and other electrical measures that will reduce annual energy consumption. ECMs are evaluated based on building use and processes, local climate conditions, building construction type, function, operational schedule, existing conditions, and foreseen future plans. When new equipment is proposed, energy consumption is calculated based on the manufacturer’s cataloged information. Energy savings are calculated by AkWarm. Implementation of more than one ECM often affects the savings of other ECMs. The savings may in some cases be relatively higher for an ECM implemented individually than when that ECM is just one of multiple recommended ECMs. For example, implementing reduced operating schedules of inefficient lighting systems may result in a given savings. Also implementing a more efficient lighting system will add to the savings, but less than the efficient lighting would alone because there is less energy to be saved when the lights are on a reduced operating schedule. Thus, if multiple ECM’s are recommended, the combined savings are calculated and identified appropriately in groups. In Appendix D, Energy Conservation Measures, the simple lifetime calculation is shown for each ECM, which is based on the typical life of the equipment being replaced or altered. The energy savings are extrapolated throughout the simple lifetime of the ECM. The total energy savings is calculated as the total lifetime multiplied by the yearly energy savings. The cost savings and installation costs are used to calculate simple payback2 and the Savings to Investment Ratio3 (SIR). These are listed in Appendix D and summarized in the Executive Summary Table of this report. The SIR is calculated as a ratio by dividing the break even cost by the initial installed cost. Cost savings is calculated based on the historical energy costs for the building. Installation costs include labor and equipment to evaluate the initial investment required to implement an ECM. These are applied to each recommendation with simple paybacks calculated. The energy analyst’s opinions of probable cost are garnered from RS Means Cost Data, other industry publications, and local contractors and suppliers. In addition, where applicable, maintenance cost savings are estimated and applied to the net savings. 2 The simple payback is based on the years that it takes for the net savings to payback the net installation cost (Cost divided by Savings). 3 Savings to Investment Ratio (SIR): Break Even Cost divided by initial installed cost, where Break-Even Cost is how much can be spent and still have the measure be cost effective; it equals the Present Value (PV) of Savings over the life of the measure minus PV of maintenance costs.

Building Description Palmer High School is a three story building with a variety of space usages and schedules. The school was originally built in 1976. Major renovations include a roof renovation and the addition of an athletic field complex and a pool in 1982, the installation of a seasonal outdoor hockey rink in 1983, school building additions and HVAC upgrades in 1985 and a fire alarm system upgrade in 1999. During the Mat- Su Borough School District (MSBSD) school year, the school is occupied by approximately 850 people from 5:30am until 10pm for school and after-school activities. Night janitorial staff works until 12am. The MSBSD school year runs from mid August thru mid May. There is an Agriculture and Greenhouse building on the property, however power is supplied to this building via an electrical connection that is separate from the school building. Thus, this building was not included in an AkWarm model for Palmer High School. V.I School Architectural Description Details of the wall, floor and roof construction were examined on the architectural drawings and confirmed during the site visit. Exterior walls surrounding the classroom areas are constructed of 2”x6” metal studs on 16” centers with R-19 insulation infill, 1/2” gypsum sheathing, and 1” stucco on metal lath. These walls are 20’ high, and have an estimated R-value of R-16.7. The exterior walls of the gym are constructed of 12” concrete blocks, a vapor barrier, 3-1/2” fiberglass batt insulation, 1/2” gypsum sheathing and 1” stucco on metal lath. These walls are approximately 40’ high and have an estimated R- value of R-16. The exterior walls surrounding the pool complex are constructed of 4” thick pre-cast concrete panels, 4” rigid insulation, and 12” CMU. These walls are approximately 32’ high and have an estimated R-value of R-17.5. The school has 4” thick concrete slab-on grade floors with 2” of rigid foam insulation covering the slab edge and extending at least 4’ below grade, providing an estimated R-value of R-16. There is approximately 99,885 sf of slab-on-grade floor area. The total usable square footage of the school, 197,494 sf, is greater than the slab-on-grade area as the school has three floors. This area includes all fan rooms, mechanical rooms, pool areas, and storage rooms. The roof is constructed of a metal deck covered by plywood decking, a 3 ply membrane, 4” rigid insulation and 2” rigid insulation under concrete pavers. While the roof insulation could not be accessed, it was estimated that the composite R-value for the roof system is R-30. The roof is scheduled to be replaced in the summer of 2012 which will bring the insulation value of the roof near R-40. There is approximately 98,885 sf of roof area. Typical window construction consists of double pane windows with 1/2” air space and anodized aluminum frames. Both fixed and operable windows were observed. The windows were installed during the original construction of the school and are approximately 36 years old. The framing seals and gaskets around the majority of the operable windows throughout the building were in poor condition resulting in excessive air infiltration and heat loss. An insulating value of R-1.2 was estimated for the windows. There is a total of 5,080 sf of window area, with 2,514 sf of south facing window area. The school has 17 insulated metal doors (R-2.5), three 3’x5’ insulated metal doors (R-2.5) and 4 insulated, overhead, sectional garage doors (R-2.9). The school entrances contain a total of 10 metal doors with half-light glass (R2.2) and 12 metal framed, full glass doors (R-1.8). There is a total of 1,481 sf of door area. Palmer High School Final Energy Audit Report Coffman Engineers, Inc. 6/13/2012 8 AkWarm No. CIRI-PAQ-CAEC-03 V.II Mechanical Description The school building is heated with two gas-fired Burnham V1123 boilers, each with an input rating of 3957 MBH, and a gas-fired Cleaver Brooks CB-700-200 fire tube boiler with an input rating of 8369 MBH. The heating system medium is water. Conduction and infiltration heating loads are accomplished with a perimeter baseboard heating system with cabinet unit heaters and horizontal unit heaters where required. Ventilation heating is provided by heating coils using glycol, which is heated by the central heating system using water-to-glycol heat exchangers located in each fan room. No mechanical cooling is provided for any systems in the facility. Heating water is circulated throughout the building’s hydronic systems, including terminal units and heating coils, by six heating water circulation pumps. HPP-1 and HPP-2 are 10 HP, base-mounted pumps that supply hydronic heating water. CP-1 and CP-2 are 7.5 HP inline pumps that also supply hydronic heating water. HWP-1 and HWP-2 are 5 HP, base-mounted pumps that supply the AHU heating coils. Pumps P-6A and P-6B are 7.5 HP base-mounted pumps that serve the pool with heating water. There are five air handling units (AHUs) serving Palmer High School. All AHUs were installed as part of the 1985 HVAC upgrades and are approximately 27 years old. The classrooms and offices are served by AHU-1, a variable air volume unit equipped with a 25 horsepower (HP) VFD-controlled motor. It is capable of serving up to 29,800 cubic feet per minute (CFM) of conditioned air. AHU-2 is equipped with a 10HP motor serving approximately 7,300 CFM of air to the gym. AHU-3 is a make-up air unit for the kitchen and is equipped with a 3HP motor serving 5,520 CFM of air to the space. The first floor locker rooms are served by AHU-4 and AHU-5 each of which provide 2,750 CFM of air using 3/4 HP motors. Domestic hot water for the school and the kitchen area is provided by three Triangle Tube Smart 120 series indirect water heaters each equipped with a 119 gallon storage tank. These indirect water heaters were installed in 2010 and are located in the boiler room. The domestic hot water line is constantly recirculated using a Grundfos, UP26-96BF, bronze in-line circulator pump. The school’s building energy management and control system is a hybrid system, using electronic transducers controlling pneumatic actuators. Compressed air is provided by two air compressors. The system was observed to be in fair working order; however, pneumatic systems are considered outdated due to the vast improvements in monitoring, control and operating efficiencies available from the modern genre of electronic control systems. The boilers are controlled by a Honeywell aquastat which limits the boiler’s firing frequency and supply hot water using three-way mixing valves. Boilers B-1 and B-2 are maintained on a low fire setting to achieve the highest possible combustion efficiency for these units. V.III Electrical Description The School is served by a 2500 Amp (A), 277/480 Volt (V), three-phase, four-wire, underground electrical service connected to a pad-mounted utility transformer. The school has a standby diesel generator used to power selected loads in the event of a power outage. Inside the school, 277/480V power is used to serve large mechanical loads. Dry type transformers are used to step the voltage to 120/208V, three phase for receptacle loads, computers, and kitchen equipment. Since the passage of the Energy Policy Act of 2005, all general purpose transformers have been required to meet the efficiency requirements listed in the National Electrical Manufacturer's Association publication NEMA TP1-2002. There are energy savings available by replacing these transformers with new models that meet or exceed the standard, however caution must be exercised as replacing transformers impacts available fault current and over-current protection device selective coordination. The replacement of the school’s existing transformers to meet NEMA requirements can only be recommended after performing a power system analysis. That level of study is outside the scope of this project. Palmer High School Final Energy Audit Report Coffman Engineers, Inc. 6/13/2012 9 AkWarm No. CIRI-PAQ-CAEC-03 The school was primarily illuminated by T12 light fixtures with magnetic ballasts. Though many of these fixtures remain, several have been retrofitted with T8 lamps and electronic ballasts or with volumetric troffer retrofit kits with T5 lamps. All of the office and classroom lighting was observed to be controlled by wall switches. The corridors are illuminated by a mix of fluorescent fixtures powered by the normal power system and fixtures powered by the standby power system. Corridor lighting is controlled by occupancy sensors and switch off while the space is unoccupied. Metal halide (MH) light fixtures are present in the gymnasium, weight room, auto shop, and the main lobby area for the school. These fixtures typically remain on even if the space is unoccupied for an extended period of time because of the long re-strike times associated with metal-halide light fixtures. Exterior lighting consists of 150W canopy lights, 150W wallpack light fixtures, 250W and 400W pole mounted parking lot lights. Both single and twin headed configurations are present for the pole mounted light fixtures. All of the lighting is high pressure sodium (HPS) with the exception of one LED wall pack fixture and a LED pole mounted area light. These lights are currently controlled by an on/off photo switch that turns the lights off during the day, and a time clock that shuts the building mounted lights off during the night at midnight, while the pole mounted light fixtures shut off at 10:00 pm. All of the exterior lights switch back on at 5:00. Other electricity-using equipment not previously described in the mechanical or electrical sections include a microwave, a walk in freezer and refrigerator, various other kitchen equipment, and various user equipment such as projectors, computers, and printers. V.IV Pool Equipment Description The pool is served by filters, a pool circulating pump, three indirect domestic hot water heaters, an air blower, and a plate and frame heat exchanger. The pool equipment was installed in 2010 and uses a gravity-fed system for cleaning the pool water. Pool capacity is approximately 250,000 gallons, and it is cycled through the filtration system approximately every 8 hours by the recirculation pump. A backwash is performed on the filtration system every 10-17 days. Pool water heating is accomplished by a heat exchanger located in the pool equipment room that is served by the school’s central heating system. Ventilation for the pool is provided by a variable volume AHU. The variable volume AHU consists of a 15 HP supply fan (F-1) equipped with a variable frequency drive (VFD) and a 15 HP return fan (F-6) equipped with a VFD. Ventilation for the spectator area of the pool complex is provided by a constant volume AHU. The constant volume AHU consists of a 1.5 HP supply fan (F-3) and a 1.5 HP return fan (F-8). Ventilation for the offices and locker rooms is provided by a constant volume AHU consisting of a 3 HP supply fan (F-5). Recirculation heating fan (F-4) has a 3/4 HP motor and runs continuously to provide heat to the Northern half of the pool area. Recirculation heating fan (F-2) has a 3/4 HP motor and runs continuously to provide heat to the Southern half of the pool area. Exhaust air is removed by fan (F- 7). Refer to Appendix C for a detailed listing of all major equipment. Lighting in the pool is provided by several 400W MH light fixtures mounted to a catwalk. Lighting for the bleachers is provided by ceiling mounted MH light fixtures. These MH fixtures remain on for the entire day due to the long re-strike time associated with MH light fixtures. The pool's locker rooms are illuminated by 4’ fluorescent T8 light fixtures. All other lighting for the pool facility is provided by 4’ and 2’ U-tube T12 light fixtures. All of the light fixtures in the pool facility are controlled by wall mounted rocker switches and were observed to remain illuminated during the pools hours of operation. Palmer High School Final Energy Audit Report Coffman Engineers, Inc. 6/13/2012 10 AkWarm No. CIRI-PAQ-CAEC-03 VI. Historic Energy Consumption and Cost Tables provided in Appendix A, Energy Benchmark Data Report, represent the electric and natural gas energy usage for the surveyed facility from January 2009 to December 2010. Matanuska Electric Association provides the electricity and Enstar provides the natural gas to the building. Both utility companies bill the facility using a commercial rate schedule. The actual utility bills were not provided to be able to verify the data received to assure 100 percent accuracy of the data. The AkWarm model of the facility was built to match the facility’s average annual electric and heating oil consumption, so that a realistic model could be created. The monthly energy consumption of the AkWarm model matches the actual average monthly consumption of the facility within 25%, which is adequate for this level of modeling. Overall, the energy consumption trends of the AkWarm model and the actual facility match appropriately. Graphical representations of the monthly energy consumption are included in Appendix A. VI.I Electrical Consumption Data The electric utility costs consist of several components: a fixed monthly customer charge, an energy usage charge, fuel surcharge, taxes, and a demand charge. The energy usage and fuel surcharge are based on the customer's usage as measured in kilowatt-hours (kWh). The usage (kWh) is determined by load wattage divided by 1,000, times hours running. For example, a 1,000 watt load operating for one hour will use 1 kWh of electricity as would ten, 100 watt lamps operating for one hour or one, 100W lamp operating for 10 hours. One kWh is equivalent to 3,413 BTU. Utility data used in this report reflects the historical data provided for the building in a summarized format. VI.II Natural Gas Consumption Data The natural gas utility measures consumption and bills in CCF of natural gas, where one CCF equals 100 cubic feet of natural gas. The average heating value of natural gas is 1,000 BTUs per cubic foot, making 1 CCF equal to 100,000 BTUs or 1 Therm. VI.III Overall Energy Consumption Data The overall cost for energy use is calculated by dividing the total cost by the total usage. Based on the electric and natural gas utility data provided, the average cost for the energy and consumption calculations at the surveyed facility are summarized in the table below. Table 2. Energy Cost and Consumption Data Energy Cost and Consumption Data 2009 2010 Average Electric 0.14 $/kWh 0.11 $/kWh 0.12 $/kWh Natural Gas 1.01 $/CCF 0.84 $/CCF 0.92 $/CCF Total Cost $386,138 $290,193 $336,706 ECI 1.96 $/sf 1.47 $/sf 1.72 $/sf Electric EUI 28.2 kBtu/sf 27.3 kBtu/sf 27.8 kBtu/sf Natural Gas EUI 81.6 kBtu/sf 68.3 kBtu/sf 75.0 kBtu/sf Building EUI 109.8 kBtu/sf 95.6 kBtu/sf 102.7 kBtu/sf Palmer High School Final Energy Audit Report Coffman Engineers, Inc. 6/13/2012 11 AkWarm No. CIRI-PAQ-CAEC-03 The Energy Cost Index (ECI) is derived by dividing the annual cost by the building square footage. The building square footage was calculated to be approximately 197,494 square feet. This area includes the main building, the fan rooms, and the pool. The annual EUI is expressed in Thousands of British Thermal Units per Square Foot (kBtu/sf) and can be used to compare energy consumption of similar building types or to track consumption from year to year in the same building. The EUI is calculated by converting annual consumption of all fuels used to Btu’s and then dividing by the area (gross conditioned square footage) of the building. EUI is a good indicator of the relative potential for energy savings. A comparatively low EUI indicates less potential for large energy savings. Building architectural, mechanical, and electrical drawings were obtained and utilized to calculate and verify the gross area of the facility. The gross area was confirmed on the physical site investigation. Palmer High School Final Energy Audit Report Coffman Engineers, Inc. 6/13/2012 12 AkWarm No. CIRI-PAQ-CAEC-03 VII. Equipment Inventory and Photo Survey Following the completion of the field survey a detailed equipment list was created and is attached as Appendix C. The major equipment listed are considered to be the major energy consuming equipment in the building whose replacement could yield substantial energy savings. An approximate age was assigned to the equipment if a manufactured date was not shown on the equipment’s nameplate. As listed in the 2011 ASHRAE Handbook for HVAC Applications, Chapter 37, Table 4, the service life for the equipment along with the remaining useful life in accordance to the ASHRAE standard are also noted in the equipment list. Where there are zero (0) years remaining in the estimated useful life of a piece of equipment, this is an indication that maintenance costs are likely on the rise and more efficient replacement equipment is available which will lower the operating costs of the unit. Maintenance costs should also fall with the replacement. Additionally, photos of various equipment and the building construction were taken during the site survey. Several photos are included in Appendix E. CEI made miscellaneous thermographic images of the building using a FLIR T300 Infrared Camera. This is not a thermographic study, but rather just a few snapshots to illustrate easy-to-identify heat losses. These thermographic photos are included in Appendix F.

Energy Conservation Measures The following ECMs described here have been calculated by AkWarm Commercial and considered by the energy audit team as viable projects. ECMs provided below are considered to have viable financial ratios (SIR>1) or to add value to the building or building operational profiles. For a full list of ECMs considered and calculated by the energy audit team, including ECMs not recommended at this time, please see Appendix D. VIII.I School Energy Conservation Measures ECM# PHS-1 – Replace Residential & Light Commercial Refrigerators/Freezers Older Than 5 Years Old Annual Energy Savings Installed Cost SIR Payback (years) ---<10 years Due to advances in refrigerators in the previous five years, new Energy Star residential-type and light commercial-type refrigerators and freezers are much more efficient and result in viable energy savings. Built-in refrigerators and freezers should be evaluated independently. Replacing existing refrigerators, which are older than five years old, with new energy star models will typically have paybacks of less than 10 years. ECM # PHS-2 – Install A Pool Cover For Use During Unoccupied Periods Annual Energy Savings Installed Cost SIR Payback (years) $2,632 $10,000 4.23 3.8 Indoor pools lose a significant amount of energy due to pool water evaporation. Evaporated pool water requires additional ventilation air in order to control indoor humidity, in turn increasing the amount of outdoor supply air that must be tempered. By installing a pool cover, the amount of evaporated water will be minimized while the required ventilation to the space and the amount of pool make-up water will decrease. In helping control humidity, a pool cover will extend the life of the building surfaces, structure, and active mechanical and electrical systems. In an effort to conserve pool deck space, this ECM recommends purchase of a portable reel storage system. Refer to item 11 in Appendix D for more information. ECM # PHS-3 –Install VFDs on Heating Water Circulation Pumps Annual Energy Savings Installed Cost SIR Payback (years) $8,051 $42,700 2.87 5.3 It is recommended that Variable Frequency Drives (VFDs) be installed on eight heating water circulation pumps (HPP-1, HPP-2, HWP-1, HWP-2 and CP-1, CP-2, P-6A, and P-6B) so that the pumps can modulate in order to satisfy the heating load of the hydronic system for the building and the pool. Since the building is heated year round, these pumps are heavily used. Allowing the pump motors to modulate with the heating load will reduce the electricity required for pumping. An electrical engineer will need to evaluate the existing electrical layout to determine if additional infrastructure improvements are necessary to make this ECM viable. This ECM was modeled with a separate AkWarm model and as a result the item is not an additive measure in AkWarm. It is therefore not included in the final cost savings total in the final AkWarm model in Appendix D. Palmer High School Final Energy Audit Report Coffman Engineers, Inc. 6/13/2012 14 AkWarm No. CIRI-PAQ-CAEC-03 ECM # PHS-4 – Upgrade Restroom Lighting and Controls Annual Energy Savings Installed Cost SIR Payback (years) $1,033 $7,870 1.98 7.6 The lighting in the schools restrooms is provided by approximately two 52W, and two 90W incandescent lamps, 34 two-lamp T12 light fixtures and (2) two-lamp T5 fixtures. Four of the T12 fixtures are powered by the standby electrical system and are used as night lights. This ECM includes replacing the incandescent lamps with compact fluorescent lamps (CFL), and replacing all of the T12 light fixtures one- for-one with T8 fixtures. Each restroom should be provided a ceiling mounted occupancy sensor that switch the light fixtures off while the space is un-occupied. This description is for a compilation of several ECMs that are intended to be implemented at the same time. However, due to constraints with the AkWarm modeling software, the different lighting configurations were modeled separately. See items 6, 12, 15, 18, and 31 in Appendix D for details of individual measures. ECM# PHS-5 – Setback Thermostat for School Annual Energy Savings Installed Cost SIR Payback (years) $15,590 $114,000 1.74 7.3 Significant energy savings exist by reducing the room temperatures in the school during unoccupied times. By reducing the temperature of these spaces to 60°F during unoccupied times, the heating load required will be reduced. The cost of this ECM includes the cost of replacing 57 existing thermostats with new programmable thermostats, installing 57 electronic to pneumatic transducers, and connecting the transducers to the existing DDC system at a cost of $2,000 per thermostat. A DDC contractor will need to evaluate the existing DDC system to determine if infrastructure improvements are necessary to make the afore mentioned ECM viable. See items 1, 26, and 71 in Appendix D for more information. ECM # PHS-6 – Upgrade Locker Room Lighting and Controls Annual Energy Savings Installed Cost SIR Payback (years) $2,274 $21,600 1.62 9.5 The lighting in the locker rooms is provided by approximately 18 wet location listed 100W metal halide light fixtures, and 103 two-lamp T12 light fixtures. Six of the T12 fixtures are powered by the standby electrical system and are used as night lights. It is recommended that every light fixture including the metal halide fixtures are replaced one-for-one with two-lamp T8 fixtures. Additionally ceiling mounted light fixtures should be provided to switch the fixtures off while the spaces are unoccupied. This ECM does not include the locker rooms in the pool area. This description is for a compilation of several ECMs that are intended to be implemented at the same time. However, due to constraints with the AkWarm modeling software, the different lighting configurations were modeled separately. Refer to items 14, 29, and 33 in Appendix D for details of individual measures. Palmer High School Final Energy Audit Report Coffman Engineers, Inc. 6/13/2012 15 AkWarm No. CIRI-PAQ-CAEC-03 ECM # PHS-7 – Repair Burnout Domestic Hot Water Pump Motors with EC motors Annual Energy Savings Installed Cost SIR Payback (years) $175 $1,700 1.56 9.7 New, high efficiency pumps with electronically commutated (EC) motors have integral speed controls which read system demand, allowing the pump to slow down with significant electrical savings. Replacing the existing domestic hot water circulation pumps with new pumps with EC motors now (while the existing motors are still functional) will result in a $6,115 replacement cost with an annual energy savings of $173 and a simple payback of 34.9 years. However, upgrading to pumps with EC motors when the existing pumps fail and are in need of repair will offer a much better payback, because the marginal cost of choosing a high efficiency EC motor over the standard efficiency replacement motor is only a $535 repair cost, since the motor needs to be replaced anyway. The three domestic hot water circulation pumps, located in the boiler room, were installed in 2010 and have an estimated 8 years of remaining service life. This ECM was modeled with a separate AkWarm model and as a result the item is not an additive measure in AkWarm. It is therefore not included in the final cost savings total in the final AkWarm model in Appendix D. ECM # PHS-8 – Upgrade Pool Fluorescent Lighting Annual Energy Savings Installed Cost SIR Payback (years) $1,036 $12,250 1.30 11.8 This ECM affects all portions of the school's pool section that are illuminated by fluorescent light fixtures including corridors, offices, locker rooms, and mechanical spaces. These general use areas in the pool section of the school are primarily illuminated by 4’ fluorescent light fixtures. Approximately 30 two- lamp T8 fixtures are used in the locker rooms. Four U-tube T12 fixtures are used in the staff locker rooms and corridors. Approximately 50 two-lamp and 2 four-lamp T12 fixtures illuminate the pools corridors, lobby, offices, mechanical spaces, handicap accessible restrooms, storage areas, and staff locker rooms. This ECM consists of replacing every four-foot T12 one-for-one with a T8 fixture, and replacing the U- tube fixtures one-for-one with four-foot T8 fixtures with two-lamps. Additionally, occupancy sensors should be provided to control approximately 20 T8 fixtures in the locker rooms, switching the locker area in one zone, and the restroom/shower area as another zone, however approximately five fixtures should remain un-controlled by the occupancy sensors to provide a small amount of illumination while the most of the fixtures are switched off. The pilot switches that control the fan room lighting should be replaced so that pool personnel know when these fixtures are switched on. Additionally occupancy sensors should be provided to control all of the newly retrofitted T8 fixtures with the exception of the fixtures located in the mechanical rooms and the fixtures in the main entrance. This description is for a compilation of several ECMs that are intended to be implemented at the same time. However, due to constraints with the AkWarm modeling software, the different lighting configurations were modeled separately. See items 10, 21, 24, 25, 28, 32, 35, 39, 40, 83, and 93 in Appendix D for details of individual measures. Note – AkWarm measures with SIRs less than one were included in this compiled annual energy savings, installed cost, SIR, and payback of this since the measures should be implemented congruently. Palmer High School Final Energy Audit Report Coffman Engineers, Inc. 6/13/2012 16 AkWarm No. CIRI-PAQ-CAEC-03 ECM # PHS-9 – Upgrade Corridor Lighting Annual Energy Savings Installed Cost SIR Payback (years) $2,658 $33,300 1.23 12.5 The corridors and lobbies in the school are illuminated by recessed metal halide down lights, and four foot fluorescent T5, T8, and T12 fixtures. Approximately 75% of these fixtures are controlled by occupancy sensors while the remaining fixtures are powered by the standby electrical system and used as night lights. It is recommended that the nine single-lamp, 193 two-lamp, and the 18 four-lamp T12 fixtures be retrofitted one-for-one to use T8 lamps and electronic program start ballasts. Additionally a new ceiling mounted occupancy sensor should be installed in the corridor adjacent to the kitchen. See items 20, 23, 27, 34, 38, 44, 52, and 65 in Appendix D for details of individual measures. ECM # PHS-10 – Upgrade Kitchen Lighting Annual Energy Savings Installed Cost SIR Payback (years) $469 $6,050 1.20 12.9 The kitchen is illuminated by approximately (3) two-lamps, and 34 four-lamp fluorescent T12 fixtures. Two of the four-lamp fixtures are used as night lights. All 37 of the T12 light fixtures should be retrofitted with T8 lamps and electronic ballasts. Additionally the two existing night lights should be switched with the existing lighting circuit, while two "bug-eye" type emergency lights be added to illuminate the path of egress in the event of a power outage. Refer to items 5, 69, and 79 in Appendix D for more information. ECM # PHS-11– Upgrade Pool High-Bay Lighting Annual Energy Savings Installed Cost SIR Payback (years) $3,092 $46,200 1.03 14.9 The natatorium is illuminated by approximately 44 400W metal halide (MH) high bay light fixtures mounted to a catwalk. The bleachers are illuminated by six similar fixtures mounted to the ceiling, and two ceiling mounted fixtures are present behind the diving boards. It is recommended that each of the MH fixtures be replaced one-for-one with six-lamp T5HO light fixtures listed for use in natatoriums. Additionally occupancy sensors should be used to control the six light fixtures illuminating the bleachers. See items 45 and 49 in Appendix D for more information. ECM # PHS-12 – Perform Air Sealing to Reduce Air Leakage by 20% Annual Energy Savings Installed Cost SIR Payback (years) $4,516 $40,000 1.02 8.9 By tightening the building envelope with air sealing improvements, infiltration into the building will be reduced. This in turn will reduce the heating load required by the building and reduce the amount of natural gas being burned by the boilers. While a blower door test was not completed, it is anticipated that air leakage is occurring through old weather stripping around doors, damaged gaskets in operable window frames, and wall and roof penetrations. Methods to decrease the infiltration into the building include: sealing around the windows and doors with caulking and insulation, adding new weather stripping to doors, providing gaskets to all exterior cover plates and sealing all roof and wall penetrations. Also, inspect and repair louvers and dampers within each AHU. To achieve a viable economic benefit, up to $40,000 can be invested and still achieve an SIR ≥ 1 by reducing air leakage by 20%. See item 50 in Appendix D for more information. Palmer High School Final Energy Audit Report Coffman Engineers, Inc. 6/13/2012 17 AkWarm No. CIRI-PAQ-CAEC-03 ECM # PHS-13 – Upgrade Classroom Lighting Annual Energy Savings Installed Cost SIR Payback (years) $10,741 $165,867 1.00 15.4 The classrooms and wood shop in the school are illuminated by recessed 400W metal halide down lights, and four foot fluorescent T5, T8, and T12 fixtures. Approximately 95% of these fixtures are controlled by wall switches and the remaining fixtures are powered by the standby electrical system and used as night lights. It is recommended that the 30 metal halide light fixtures be replaced one-for-one with six-lamp T5HO light fixtures. The 74 two-lamp, 606 three-lamp, and the 18 four-lamp T12 fixtures should be retrofitted one-for-one to use T8 lamps and electronic program start ballasts. Additionally a new ceiling mounted occupancy sensor should be installed in each of the approximately 78 classrooms with the exception of the wood shop. ECM # PHS-14– Upgrade Gym Lighting Annual Energy Savings Installed Cost SIR Payback (years) $2,321 $36,000 0.99 15.5 Though this ECM does not have a SIR greater than one it is recommended that the 42 existing 400W MH gymnasium light fixtures be replaced one-for-one with six-lamp fluorescent T5HO light fixtures. Occupancy sensors should also be installed to switch the light fixtures off while the space is unoccupied for extended periods of time. Besides energy savings, fluorescent fixtures have added benefits over MH fixtures which include better color rendering, multi-level and frequent switching capabilities making them ideal for use with occupancy sensors. See item 51 in Appendix D for more information. Palmer High School Final Energy Audit Report Coffman Engineers, Inc. 6/13/2012 18 AkWarm No. CIRI-PAQ-CAEC-03 VIII.II Administrative Controls for Energy Conservation and Optimization While the intent of many energy conservation measures is to increase the efficiency of fuel-burning and electrical equipment, an important factor of energy consumption lies in the operational profiles which control the equipment usage. Such profiles can be managed by administrative controls and departmental leadership. They determine how and when fuel-burning and electrical equipment are used, and therefore have a greater impact on energy savings potential than simply equipment upgrades alone. Significant energy cost savings can be realized when ECMs are combined with efficient-minded operational profiles. Operational profiles may be outlined by organization policy or developed naturally or historically. These profiles include, but are not limited to: operating schedules, equipment setpoints and control strategies, maintenance schedules, and site and equipment selection. Optimization of operational profiles can be accomplished by numerous methods so long as the intent is reduction in energy-using equipment runtime. Due to the numerous methods of optimization, energy cost savings solely as a result of operational optimization are difficult to predict. Quantification, however, is easy to accomplish by metering energy usage during and/or after implementation of energy-saving operational profiles and ECMs. Shown below are some examples which have proven successful for other organizations. Optimization of site selection includes scheduling and location of events. If several buildings in a given neighborhood are all lightly used after regularly occupied hours, energy savings can be found when after- hours events are consolidated and held within the most energy efficient buildings available for use. As a result, unoccupied buildings could be shut down to the greatest extent possible to reduce energy consumption. Two operational behaviors which can be combined with equipment upgrades are operating schedules and equipment control strategies including setpoints. Occupancy and daylight sensors can be programmed to automatically shut off or dim lighting when rooms are unoccupied or sufficiently lit from the sun. Operating schedules can be optimized to run equipment only during regular or high-occupancy periods. Also, through a central control system, or with digital programmable thermostats, temperature setpoints can be reduced during low-occupancy hours to maximize savings. In addition, sporadically used equipment can be shut down during unoccupied hours to further save energy. In general, having equipment operating in areas where no occupants are present is inefficient, and presents an opportunity for energy savings. Operational profiles can also be implemented to take advantage of no- or low-cost ECMs. Examples include heating plant optimizations (boiler section cleaning, boiler flush-through cleaning) and tighter controls of equipment setbacks and shutdowns (unoccupied zones equipment shutdown, easier access to and finer control of equipment for after-hours control). In a large facility management program, implementation of these measures across many or all sites will realize dramatic savings due to the quantity of equipment involved. Changes to building operational profiles can only be realized while simultaneously addressing health, safety, user comfort, and user requirements first. It is impractical to expect users to occupy a building or implement operational behaviors which do not meet such considerations. That said, it is quite practical for management groups to implement administrative controls which reduce losses brought about by excess and sub-optimum usage.
