AirTest DCV (Demand Control Ventilation) was retrofitted on to this 6,130 sq/m parking garage in San Francisco.

10 AirTest TR2000 CO Transmitters, an AirTest CN7216 Controller, and 5 VFDs were installed on this ventilation system with a 130hp fan capacity.

AirTest’s DCV solution was able to produce a 93.9% annual reduction in energy consumption.

By making this parking garage smart with AirTest sensors there was a reduction of 138,360 kg of greenhouse gasses produced and a savings of 226,898 kWh each year.

The payback period on investment was under 2 years.
