Bringing Central Air to a 1930s-Era School

Because of the size of the school, we ruled out a decentralized unit ventilator system. Instead, we chose an exterior chiller that runs chilled water to each classroom — a more economical yet still centralized solution. We also fitted a rooftop unit on the cafeteria, added a cooling coil to the gym air handler and completely upgraded the boiler system. To accommodate these improvements, we brought in new electrical service and used the massive crawl space underneath the school to house most of the piping. New building automation controls allow the facilities team to manage temperature and humidity and diagnose problems remotely.
