Among its buildings, Miami Valley Hospital South in Centerville, Ohio includes a 60,000 square foot medical office building, a state-of-the-art cancer center and a main hospital unit. During routine HVAC maintenance, the facility’s test and balancing experts found that leaks, common throughout many of the duct systems employed on campus, were leading to significant HVAC performance inefficiencies. With an ongoing mandate to reduce energy use, hospital administrators knew that by fixing the leaks, they could potentially save a substantial amount of energy.
