3.3.4 Water Water is provided by Eugene Water & Electric Board (EWEB). The total annual water usage cost in 2015 for the airport was $2,228. The total annual sewage usage cost in 2015 for the airport was $142. 3.4 HEATING, VENTILATION, AND AIR CONDITIONING (HVAC) SYSTEMS Cooling for the cargo processing and screening area is provided by three outdoor Air Cooled Condensing Unit (ACCU) and associated indoor Force Air Furnace (FAF) with heating and cooling coil. In addition, cooling of office is provided by four Package Terminal Heat Pump (PTHP) with electric heating coils. Heating for the cargo space is provided by gas fired FAF with duct and air grille. Ventilation are provided by thermostatic controlled wall mounted exhaust fan with intake air louver, motorized damper and filter. De-stratification fans are installed in most space to increase the air circulation. The central HVAC equipment is controlled by time clock and individual standalone controls. Most of the time clock controls for the central equipment was manually overridden to allow the equipment to run continuously. There is no Building Automation System (BAS).

There is no overall building lighting control system for automatically shutting down lights based on time of day, but most areas are controlled by motion sensors. There are several areas inefficiently lit due to fixture with poor optics. Many areas do not take advantage of ceiling reflectance to increase the light levels. Occupancy Sensors were found in the building for all spaces except equipment rooms. All exterior lights are controlled by photocell. Most rooms exceed the ASHRE 90.1 W/SF levels, but the overall W/SF is 0.81 W/SF due to the higher efficiency of the storeroom lights. ASHRAE LEVEL 1 ENERGY AUDIT AIR CARGO BUILDING 13
