Contractor cuts solar gain with custom window curtain
A local energy services contractor, using a 210-foot motorized thermal curtain to deflect sunlight entering the windows, has reduced excessive heat gain at a racetrack clubhouse here, cutting air conditioning run-time by about 75%. Because Mobile Greyhound Park's clubhouse faces east, direct exposure to sunlight from dawn to afternoon race time, about 1 p.m., was bringing the indoor temperature to almost 100/sup 0/, according to Stan Norris, operations management for the contracting firm, Technical Energy Controls, Inc. Lowering the temperature to a comfortable level required running four Carrier Corporation air handling units, rated at a total of more than 170 tons, for about eight hours, and annual energy bills were running at about $240,000, Norris said. With the aluminum foil-backed vinyl curtain, the air handling units need only operate two hours to bring temperatures to comfort levels.
