Mason Uses Energy-Efficient Heating
George Mason University is utilizing the latest, most innovative technology to provide students with energy-efficient heating and cooling on campus. “We use a high-temperature hot water system, not steam,” said Jeffrey Counts, assistant superintendent of the heating and cooling plant at Mason. “Steam systems are common. High-temperature hot water systems are not very common. In the future, they probably will be. They are more efficient and require a lot less maintenance.” The hot water system not only provides heating for students in both classrooms and dormitories but also provides domestic hot water, which students use when they shower and brush their teeth. “Our high-temperature hot water goes through a heat exchanger at the location [of the housing facilities] and their heat exchanger converts the hot water to domestic water for the showers,” Counts said. The heating and cooling plant also utilizes a chill-water system that cools about 92 percent of the campus. Though the hot water system requires less maintenance than a steam system, there are still several things that can go wrong. According to Counts, a weld joint may break, expansion joints and the high temperature valves may leak and the slip joints might break or corrode. Slip joints […]
