The intent of this report is to evaluate energy consumption and costs and to recommend improvements to reduce consumption and costs. The American Recovery and Reinvestment Act (ARRA) provided funding for this audit with the end goal of improving the economy by reducing state-wide energy consumption and environmental impact. Cordova CMC, Cordova, Alaska imago 2011 GeoEyR 2011 Googae Audit Report Ameresco Federal Solutions Page 3 Level II Energy Audit Cordova CMC Cordova, AK Ameresco engineers conducted an energy audit at Cordova CMC during the week of July 11, 2011. The engineers were assisted primarily by the maintenance supervisor, Ken Lobe. Mr. Lobe provided valuable assistance to the Ameresco team including providing access to mechanical areas, utility data, facility drawings, and contact with other pertinent building personnel. The purpose of the audit is to identify cost-effective system and facility modifications, adjustments, alterations, additions, and retrofits. Systems investigated during the audit included heating, ventilation, and air conditioning (HVAC), interior and exterior lighting, domestic water, motors, building envelope, and energy management control systems (EMCS). A 53,700 square foot medical facility including exam rooms, offices, labs, inpatient beds, and other treatment areas is covered by this energy audit. Table ES.1 summarizes the 2010 utility cost for this facility. Table ES.1: Energy Cost Summary 2010 Energy Type _Annual Cost Electricity Fuel Oil Total $ 109,604 $ 108,991 $ 218,595 Table ES.2 lists energy conservation opportunities (ECO) with estimated cost and savings figures. ECOs 1-3 were calculated independently, therefore some savings may overlap. All other ECOs were calculated in numerical order taking previous ECO savings into account. Savings figures are estimated based on information available at the time of the audit and conforming to the level of detail recommended by ASHRAE Level II Audit standards. Costs are estimated based on industry standard references and the contractor's previously constructed energy conservation projects.

This data was collected in the REAL Preliminary Benchmark Data Form attached in Appendix A. Analysis of utility data reveals operational characteristics and usage trends which help identify savings measures. Historical utility data is also useful for establishing a baseline for future savings and benchmarking Cordova CMC against similar facilities. The site survey was conducted during the week of July 11, 2011. The first step of the site survey was a review of drawings onsite to get an overview of building construction and mechanical design. The drawings were then compared to the actual facility during a two day walkthrough of the facility which included a thorough inspection of mechanical systems, lighting, envelope, domestic water fixtures, and other energy using equipment. Referencing data collected from the drawings and the walkthrough, the audit team determined a series of ECOs feasible for implementation to analysis for cost-effectiveness. These ECOs were evaluated taking into account utility data and rates, local climate conditions, operating schedules, building occupancy, and the condition of building systems and equipment. The audit team employs proven system simulation techniques to model energy upgrades. Energy consumption of new equipment is based on up-to-date data for commercially available systems. Material costs and labor hour data is calculated from RSMeans Cost Data or other industry standards. Recent quotes or costs from other Ameresco projects are used when available. Labor rates are based on Davis -Bacon prevailing wage rates for the Cordova area. Where reliable figures are available, primarily on lighting calculations with predictable burnout rates, maintenance saving are included in savings figures. Maintenance costs are not included in controls or mechanical upgrades. Avoided costs of replacement are not included in these calculations. Audit Report Ameresco Federal Solutions Page 5 2.0 BUILDING DESCRIPTION Level II Energy Audit Cordova CMC Cordova, AK O General: Cordova CMC is a medium-sized medical center with approximately eight (8) in- patient beds, x-ray and lab facilities, a single bed ER unit, a physical therapy center and an attached minor medical center, and a substance abuse center. The building was constructed in 1985-86 with a total square footage of 53,700. The typical operating hours for the clinics and administrative areas are 8:00am to 5:OOpm, Monday -Friday. In -patient areas and the ER operate 24/7 year round. The average occupancy profile is 55 people during business hours and 20 people after hours. O Building Envelope: The exterior walls are 2-inch exterior finish system over steel stud framing with R-19 batt insulation. Windows are insulated, double glazing with wooden frames and little or no tinting. Exterior doors are either hollow metal type with or without one-fourth inch (1/4") single glazing wire glass or aluminum frame with insulating glass. Two garage areas were equipped with a total of four insulated sectional doors. The metal roof is mounted over plywood sheathing on wooden truss. The roof is ventilated through the perimeter soffit with R-33 batt insulation on the attic floor above the vapor barrier. Maintenance staff did report trouble with roof leaks, but the attic insulation was in good condition. Insulation and window characteristics approach the ASHRAE Advanced Energy Design guideline for new facilities and upgrades are Audit Report Ameresco Federal Solutions Page 6 Level II Energy Audit Cordova CMC Cordova, AK not recommended. The table below summarizes the thermal resistance characteristics of building envelope components. Table 2.1: Envelope Summary Exterior Walls Roof Exterior Doors Exterior Windows 20.0 34.0 1.1-1.6 1.7 OO Air Distribution: The building has seven (7) Trane central air handling units (AHUs). AH-1 is a variable air volumes (VAV) unit with inlet guide vanes that serve 24 terminal boxes with reheat coils in the admin and medical clinic areas on the main level. AH-1 is equipped with a hot water (HW) heating coil and a chilled water (CHW) cooling coil. AH-2 is a constant volume (CV) unit with only a HW coil serving the "surgery" area. AH-3 is similar to AH-2 and serves patient rooms. AH-4 is CV with HW and CHW coils and serves the building core. AH-5 is CV with HW coil and serves the lower level. AH-6 is CV with a HW coil and serves as the makeup air unit for the kitchen exhaust hood. Terminal units for AH-2 through AH-6 are equipped with supplemental heating and cooling coils. AH-7 is CV with no coils and provides outdoor air for the mechanical room. O Ventilation and Exhaust: A common outside air (OA) plenum serves AH-1-7. Six exhaust fans (EF) are located in the attic and one on the roof. EFs 1-3 are equipped with glycol heat recovery coils which pre -heat incoming OA at the plenum. The circulating pump for the heat recovery loop was running during the visit even though OA pre -heating was not desirable. The exhaust fans are not interlocked with AHUs and seem to run 24/7. Running exhaust fans when AHUs are shutdown results in improper building pressurization which can draw moisture into the building envelope and adversely affect unoccupied temperature control. Currently AHUs also run 24/7 with OA dampers open bringing outside air into the building at all times. Improvements to the ventilation and exhaust system would include several changes. First, the system would bring in OA to satisfy ventilation requirements only during occupied hours. Additional OA would be brought into the building via an economizer cycle when OA conditions are conducive to free -cooling. EFs would be engaged to achieve a neutral or near neutral building pressure. Some medical areas have special pressurization requirements and these would be taken into account. Also, space usages have changed significantly from original designs. Over ventilation of spaces with reduced requirements is also wasteful. Addressing and correcting these issues is part of ECO 1 - DDC EMCS and ECO-2 HVAC Retro-commissioning. Audit Report Ameresco Federal Solutions Page 7 Level II Energy Audit Cordova CMC Cordova, AK O Heating: HW for heating is provided by two redundant 3766 MBH input Burnham boilers. The original burners have been replaced with Power Flame burners. Three pairs of redundant pumps provide HW circulation. The AHU HW coil loop, the duct and terminal HW coil loop, and the perimeter baseboard loop are each served by one pair of pumps. For each loop one pump is run year round to prevent system leaking. All pumps are CV with three-way valves on the majority of equipment. Initial analysis indicates that the boilers may be over sized for the actual building load. O Cooling: A 50-ton Trane chiller is installed in the mechanical room and appears to be in fair condition but is never run. Cooling is accomplished with natural ventilation from open windows and portable fans. Associated pumps were also de -energized and appeared in similar condition. O Controls: A Johnson Controls pneumatic system was originally installed and appeared to be relatively well maintained. Staff reported short cycles on the system compressor which indicates system leaks. Behavior of some terminal devices also indicated controls malfunction. The time clocks originally installed have had all scheduling pins removed due to difficulty of use and inadequate building warm-up control. Perimeter baseboards have thermostatic valves with sensors located too close to the heaters causing them to close prematurely. Maintenance personnel have started replacing baseboards in trouble areas with retrofit kits which allow for occupant adjustment. O Lighting: Interior lighting consists mainly of T12 fluorescents. Additionally, there are a moderate number of incandescent can fixtures. In several offices under -shelf T12 task lighting is present. Fixtures are controlled by single -zone switching except in larger areas, most of which have multiple circuits by zone and a few with multi -level switching of three (3) lamp fixtures. Light levels vary in the building. Most areas were within the ranges recommended by Illuminating Engineering Society (IES). A few areas had excessive lighting and might be suitable for de-lamping, most notably the rooms which were intended to be surgical areas. Most exit signs employ either incandescent or fluorescent lamps but a few signs are equipped with LEDs. Exterior lighting consists primarily of 60W incandescent down lights and some halogen floods. Parking lot pole lamps are 250W high pressure sodium (HPS). O Process Loads and Miscellaneous Equipment: Medical air and vacuum equipment are present. A small Hurst boiler provides steam for sterilization. A full service kitchen also contributed to energy consumption and heat load. Computer load is typical for a medical office setting and common rooms had a few large televisions that were on but not in use at the time of the visit. There is also an onsite laundry for soiled linens. O Domestic Water: Domestic water is used in patient room showers and lavatories as well as kitchenettes and lavatories for staff and guests. Hot water is provided indirectly from the heating Audit Report Ameresco Federal Solutions Page 8 Level II Energy Audit Cordova CMC Cordova, AK HW loop via several heat exchangers. The heat exchangers are equipped with circulating pumps connected to demand sensors. Plumbing fixtures included 1.6 gallons per flush (gpf) toilets, 1.5 gallons per minute (gpm) lavatory sinks, and 2.2 gpm showerheads. These fixtures are compliant with standard s set by the 1992 Energy Policy Act and no further upgrades are recommended at this time. Pictures of general equipment and building conditions as well as thermal images of some building features follow this section. A list of major mechanical equipment is available in Appendix C.

Electricity is provided by the Cordova Electrical Cooperative. Fuel oil is supplied by Shoreside Petroleum, Inc. Fuel oil is used primarily in boilers for hydronic space heating and indirect domestic hot water (DHW) heating via heat exchangers with the boiler system. In addition to plug loads and hospital operations, electricity is used for space cooling. The tables below summarize the annual utility consumption of the site.

However, heating fuel consumption is higher than both the climate zone 1 average and the outpatient healthcare facility average. The lower -than -average density of workers at Cordova CMC compared to other healthcare facilities may explain part of the lower -than - average electric usage, but the primary difference is the lack of cooling. A chiller was installed during building construction but is never run. The need to run the boiler year round to supply the domestic hot water system may contribute to this increased usage. Maintenance staff also circulates heated water through the whole building in an attempt to reduce thermal expansion cycling in the hot water piping to prevent leaking. 3.2 Electricity Cordova CMC purchases electricity from Cordova Electrical Cooperative. The blended average FY10 rate was $0.19/kWh. For FY09 the rate was $0.22/kWh. The blended rate fluctuates monthly depending somewhat on demand but is more greatly affected by the Fuel Cost Adjustment (FCA). Cordova CEC generates electricity via both hydroelectric dams and diesel generators. The capacity of the hydroelectric dams is dependent on seasonal water flows. When water flows are higher and dam capacity is up, the FCA remains low. Otherwise, the blended rate increases. The energy rate schedule is calculated as follows: Basic Charge: $60.00/month Demand Charge: $8.40/kW Energy Charge: $0.169/kWh Fuel Cost Adjustment: Varies Cordova CMC FY09 and FY 10 usage and cost data is presented in the figure below. Audit Report Ameresco Federal Solutions Page 13 60,000 50,060 Electric Consumption (kWh) Level II Energy Audit Cordova CMC Cordova, AK Cordova Community Medical Center - Electric Consumption (kWh) vs. Electric Cost ($) Jan Feb Mar Apr May Jun Jul Aug.

Since the site does not use its cooling equipment and hot water pumps are run year round, this lack of pattern seems to make sense. The cost of electricity does not track well with usage due to the large fluctuations of the FCA. 3.3 Fuel Oil Cordova CMC purchases Fuel Oil from Shoreside Petroleum, Inc. The average FY10 fuel oil cost was $2.54/Therm. The average FY09 fuel oil cost was $2.08/Therm. Unit cost has consistently increased over the past two years. Fuel oil is stored in an onsite tank with a working capacity of about 2900 gallons and is trucked to the site in 2000 gallon maximum increments. Cordova CMC FY09 and FY10 usage and cost data is presented in the figure below.

Discussion with staff seems to indicate this pattern is atypical. Cost tracks precisely with usage, but unit cost has gradually increased over time. Audit Report Ameresco Federal Solutions Page 15 4.0 ENERGY CONSERVATION OPPORTUNITIES Level II Energy Audit Cordova CMC Cordova, AK Table 4.1 summarizes the ECOs identified during the energy audit and evaluated for implementation. Potential ECOs for this report were identified based on observations made during the energy audit, a review of historical energy consumption data, building drawings, and input from maintenance personnel. These opportunities were evaluated for detailed savings, cost estimate, and life -cycle costs. A description of each energy conservation opportunity is also provided in this Section. Table 4.1: ECO Summary ECO #1l ECO Description Annual Savings Total Cost Simple Payback 1 DDC EMCS 2 HVAC Retro-commissioning 3 Boiler Upgrade 4 Premium Efficiency Motors 5 T8 Lighting Upgrade 6 Install Occupancy Sensors 7 CFL Lighting Upgrade 8 LED Exit Sign Upgrade 9 Exterior LED Lighting 10 Weather-stripping 26,432 $ 8,287 $ 6,408 $ 1,211 $ 20,310 $ 3,044 $ 1,497 $ 886 $ 1,640 $ 633 $ 371,385 76,422 119,034 18,327 92,004 9,054 1,556 1,298 14,889 3,329 14.1 9.2 18.6 15.1 4.5 3.0 1.0 1.5 9.1 5.6 ECO 1 — DDC Energy Management & Control System O Summary: Throughout the building there are pneumatic manual wall thermostats for the various HVAC zones. These indoor temperature controls are typically inaccurate due to temperature drift, age, cost of maintenance of pneumatics, and frequent need for re -calibrated. These units also do not have night time setback features. In addition, pneumatic controls do not have the ability to maintain the temperature at set -point under changing load conditions. This ECO proposes installing a EMCS with direct digital control (DDC) to effectively minimize energy demand and consumption with fully automated and centralized energy management. EMCS will permit advanced energy control strategies such as operation scheduling, optimal start/stop, night setback, economizer, and hot water temperature reset. A full DDC install also allows for elimination of the air compressor for the pneumatic system. EMCS will also result in O&M savings, improved comfort, real-time continuous monitoring, and data trending. Real-time monitoring and trends allow maintenance staff to more easily troubleshoot mechanical failures and overheating zones. Audit Report Ameresco Federal Solutions Page 16 Level II Energy Audit Cordova CMC Cordova, AK O Recommendation: This ECO is feasible as with a simple payback of 14.3 years. The simple payback period is less than the 15 year median expected life of the control system. This calculation employed a conservative estimate of savings primarily driven by scheduling savings that do not included savings from advanced controls techniques. Detailed analysis will likely increase savings. Controls costs are estimated at approximately $1,600 per point with point count based on drawings of existing pneumatic system. Maintenance savings were not included in this calculation. This ECO was calculated independently of other ECOs. Savings may overlap with ECO 2 and/or ECO 3. ECO 2 — HVAC Retro-Commissioning OO Summary: A fully functional and properly balanced HVAC system is critical for comfortable and efficient operation of a building. Improper system operation can result from a variety of causes: normal wear and tear, space end use changes, or even incomplete commissioning at initial start-up. This ECO proposes a comprehensive retro-commissioning of the control systems in each building to optimize system operations. This also covers the full Test, Adjust, and Balance of all HVAC systems. Retro-commissioning reduces operating and maintenance costs and improves energy performance and occupant comfort. • Recommendation: This ECO is feasible with a simple payback of 9.2 years. The energy cost savings justify the initial investment cost. Maintenance savings were not included in this calculation. This ECO was calculated independently of other ECOs. Savings may overlap with ECO 1 and/or ECO 3. ECO 3 — Install Higher Efficiency Boilers O Summary: This ECO proposes replacing existing hot-water heating boilers with higher energy efficiency units. The existing Burnham boilers are original to the building and are approaching the end their useful service life. Boilers employing modern technology can be installed to reduce energy consumption, improve system operations, and reduce maintenance costs. The current boilers operating have a nominal efficiency of 80% whereas current generation high efficiency oil -fired boilers reach 87% efficiency. O Recommendation: This ECO is feasible with a simple payback of 18.6 years. The simple payback period is less than the 25-year median expected life of the new boilers. Maintenance savings were not included in this calculation. This ECO was calculated independently of other ECOs. Savings may overlap with ECO 1 and/or ECO 2. ECO 4 — Premium Efficiency Motors OO Summary: This ECO proposes installing National Electrical Manufacturers Association (NEMA) premium efficiency motors to replace standard and high efficiency motors. This replacement would cover all fan and pump motors 2HP and higher as well as select few with less than 2 HP. Premium efficiency motors typically increase energy efficiency by 2 to 3%. Currently AHU fans and HW pumps run 24/7 year round. However, calculations for motors Audit Report Ameresco Federal Solutions Page 17 Level II Energy Audit Cordova CMC Cordova, AK which will be scheduled off during unoccupied periods following the installation of a DDC control system had run hours reduced appropriately. OO Recommendation: This ECO is feasible with a simple payback of 15.1 years. The simple payback period is less than the 20-year median expected life of the new motors. Maintenance savings were not included in this calculation. This ECO was calculated assuming the installation of ECO 1. If ECO 1 is not implemented, savings will increase. ECO 5 —T8 Lighting Upgrade O Summary: This ECO proposes replacing existing T12 lighting fixtures with high efficiency T8 fixtures. T12 fixtures using magnetic ballasts are highly energy inefficient. Also, T12 lamps are no long in production and will be unavailable when warehouse reserves run out. Post -light levels are generally nearly equal to that of the existing lighting systems and at minimum will meet IES guidelines for spaces renovated. O Recommendation: This ECO is feasible with a simple payback of 4.5 years. The simple payback period is less than the typical 15-year length of study period for lighting upgrades. Maintenance savings due to longer life of T8 lamps with electronic ballasts are included in this calculation. ECO 6 — Install Occupancy Sensors O Summary: This ECO proposes installing sensors to shut off lighting in unoccupied spaces. Lighting systems are often left energized in unoccupied areas. Common sensing technologies include infrared, ultrasonic, and audible sound, often combining multiple types of sensing in one unit to avoid shutting off lights in an occupied area. Potential areas for occupancy control in this facility include clinic offices, the lower level storage area, the cafeteria, the PT room, conference rooms, break areas, and utility closets. OO Recommendation: This ECO is feasible with a simple payback of 3.0 years. The simple payback period is less than the typical 15-year length of study period for lighting upgrades. This ECO was calculated assuming the installation of ECO 5. If ECO 5 is not implemented, savings will increase. ECO 7 — CFL Lighting Upgrade O Summary: This ECO proposes retrofitting the existing incandescent light bulbs with compact fluorescent bulbs. Incandescent light bulbs installed in recessed fixtures, track lighting, utility closets, and other general areas. Over 75% of the energy used by an incandescent light bulb is converted into heat and is lost. Compact fluorescent light bulbs are much more efficient and can easily replace incandescent bulbs. Post -light levels will be nearly equal to that of the existing lighting systems or to IES standards for the present space usage, whichever is lower. O Recommendation: Applied to the buildings above, this ECO is feasible as a stand-alone measure with a simple payback of 1.0 years. The simple payback period is less than the typical Audit Report Ameresco Federal Solutions Page 18 Level II Energy Audit Cordova CMC Cordova, AK 15-year length of study period for lighting upgrades. Maintenance savings due to longer life of CFL lamps are included in this calculation. ECO 8 — LED Exit Sign Upgrade • Summary: This ECO proposes replacing the existing incandescent and compact fluorescent exit signs with light emitting diode (LED) units. LED exit signs are typically 2.0 watts per unit. OO Recommendation: This ECO is feasible as a stand-alone measure with a simple payback of 1.5 years. The simple payback period is less than the typical 15-year length of study period for lighting upgrades. Maintenance savings due to longer life of LED lamps are included in this calculation. ECO 9 — Exterior LED Lighting O Summary: This ECO proposes replacing HID exterior lighting with LED lighting. New advanced LED fixtures are commercially available to replace outdoor building and roadway lights. These fixtures have similar output, longer service life, and better lumen maintenance OO Recommendation: This ECO is feasible as a stand-alone measure with a simple payback of 9.1 years. The simple payback period is less than the typical 15-year length of study period for lighting upgrades. Maintenance savings due to longer life of LED lamps are included in this calculation. ECO 10 — Weather Stripping • Summary: This ECO proposes applying weather stripping to exterior door perimeters to reduce air infiltration into the buildings. Reducing infiltration improves building performance by reducing envelope heat loss. Many building doors have existing weather stripping material which is worn or missing. Replacing this weather stripping will have significant impact. O Recommendation: This ECO is feasible with a simple payback of 5.6 years. The simple payback period is less than the typical 25-year length of study period for envelope measures. O Recommendation: Applied to the buildings above, this ECO is feasible as a stand-alone measure with a simple payback of 7.4 years. The energy cost savings justify the investment costs.
