Solar Heat Recovery for Dulles Fire Station

DATE: Spring 2008

Many buildings at Dulles International Airport, outside Washington, DC, are covered in corrugated metal siding painted a dark “Dulles Gray”. Early tests showed that the siding panel temperature exceeded 100 degrees F on a 40 degree winter day.

The Energy Manager contracted with American Solar to install a solar heat recovery system for Fire Station 303 at the Airport. The system uses matching external metal plenums and solar fans to recover the solar heated air and supply it to the building. The solar heated air is used for space heating and hot water preheating.
