Grace Cathedral

Project Summary

This beautiful church in San Francisco was able to save 93% annually on the cost of ventilating their parking garage after installing AirTest DCV (Demand Control Ventilation). The parking facility has a 40hp fan capacity and is 4,180 sq/m in size. After installing 6 AirTest TR2000 CO Transmitters, an AirTest CN7216 Controller, and 2 VFDs the parking facility shed 55,900 kWh of annual energy consumption. This means an annual reduction of 34,100kg of greenhouse gasses. The payback period on this project, based on energy savings, was 3 years.
