Fire Department, Jessamine County, Ky.

Fire DepartmentFor Fire Chief Mike Rupard, maintaining constant temperatures within his firehouse was a costly year-round struggle. Eight 14 by 14-foot glass doors surrounded by brick and mortar are capped by a 12,000-square-foot peaked steel roof. In the winter, heat escaped through the roof and the fire truck's pumps were freezing. During the summer, it simply felt like an inferno.

High ceilings in the bay area forced gas heaters to run constantly during the winter to keep the environment warm. While the temperature at the ceiling level remained a constant 70 F, the occupants at the floor level were experiencing temperatures in the 50s. With the installation of a 16-foot diameter Big Ass Fan, Rupard was finally able to achieve the desired air circulation to eliminate temperature discrepancies and disperse emissions. By slowing the fan speed during the winter, the warm air collecting at the roof is mixed throughout the space, creating uniform temperatures from ceiling to floor without creating a draft. This air balance has made the department workout facility, located on an open mezzanine above the truck bays, far more bearable.

During the summer the fan speed is increased to create gentle breezes. "When we open the bay doors and crank our Big Ass Fan we get a nice breeze that runs through the station, keeping us very comfortable," says Rupard.
