AirTest Technologies recently declared that the garage ventilation system that uses its carbon monoxide sensor installed at a garage in San Francisco recorded a 93.9% kilowatt per hour savings and 95.7% peak kilowatt reduction. Engineers at the Pacific Gas & Electric confirmed this statement.
Nagle Energy Solutions, a consulting company that sells and installs green-technology, developed and installed the system. The demand control ventilation system deploys a smart-control technology to track and determine the level of carbon emission from vehicles in the confined space of the garage. It then adjusts fan speeds to control carbon levels to below 10ppm over long periods. This facilitates energy savings of 95%. The fan also provides constant ventilation to make sure that both the people working in the garage and visitors are not affected by the carbon emissions.
The DCW system at the garage is expected to recover installation costs within the next two years.
