<br />FIGURE 10: AIR CARGOBUILDING PERCENTAGE OF TOTAL ANNUAL ENERGYCONSUMPTION FOR EACH UTILITY TYPE IN 2015 <br /> <br /> <br /> <br />The 2015 site electrical and gas Energy Cost index (ECI) is $ 0.6/sf/yr. The 2015 site electrical and gas <br />Energy Utilization index (EUI) is 34.7 kBTU/sf/yr. This is high compared to the national median for Non- <br />Refrigerated Warehouse, which is 19.2 kBTU/sf/yr. The high electrical EUI is due to many potential reasons: <br /> <br />» Inefficient lighting fixtures. A large number of T8 3 lamp parabolic fixtures were observed in the <br />building. <br />» Most rooms exceed the ASHRE 90.1 W/SF levels so by about 200%. <br />» Lack of an efficient control system for HVAC and lighting systems <br />» Improper set points and settings for temperature set points and equipment operation control <br />» HVAC equipment set to run continuously, regardless of demand <br />» Excess infiltration and introduction of unconditioned outside air <br />» Large walk-in cooler used by Alaska Airlines. The cooler will increase the power index, but would only <br />be responsible for a portion of the increased power consumption. The exact use and requirements for <br />the cooler are unknown. The cooler is not a candidate for energy conservation measures at this time. <br />3.3.2 Electricity <br />Electricity is metered and billed based on the meter readings. The air cargo building has multiple meters <br />throughout its property. <br />3.3.3 Natural Gas <br />Natural gas is metered and billed based on the meter readings. Natural gas is mainly use for heating <br />through the Forced Air Furnaces (FAF) in the building. The annual natural gas consumption is 15% of the <br />total energy consumption in MBH as shown in Figure 8. <br /> ASHRAE LEVEL 1 ENERGY AUDIT AIR CARGO BUILDING 12 <br /> <br />
