ATI Airtest Technologies, Inc. announced that its innovative, carbon monoxide (CO) sensor system has recently been installed at the Westin St. Francis Hotel in San Francisco. The reduction in energy consumption for the garage ventilation system was confirmed at 94.7%.

Engineers for the regional, public utility verified postinstallation power (kW) measurements showing an annual energy savings of 222,999 kWh and 25.5 peak kW ­ all while running the property's garage fans on a 24/7 basis. As a result, the Westin St. Francis Hotel's annual garage ventilation costs have been cut from $36,650 to just $1,779 a year ­ a 94.7% decrease.

The system will pay for itself in just 14.85 months.
