Our DCV (Demand Control Ventilation) solutions were implemented in the parking garage at Sunset Millennium in West Hollywood. Our results were astounding but not unusual for AirTest DCV in parking garage applications. In this 1000 car facility with 8 fans and 242hp we installed 41 sensors using the existing conduit. AirTest developed the plans using AirTest TR2000 sensors and an AirTest CN8000 Control Panel. This resulted in 1 year operational savings of $220,000 (1.3m kWh). Payback period on investment was 9 months and 100% of the cost was covered by rebates.
