The Building America program of the US Department of Energy is supporting projects focused on residential air-conditioner and heat pump faults. One project examines how common it is for installation faults to occur, based on a large national study of houses in the US; another project proposes a way to use smart thermostats to diagnose faults; and a third project examines the effectiveness of methods for detecting and diagnosing faults. These presentations will give the latest results of current cutting-edge research on residential system faults, and a rare glimpse into the future of high-performance home comfort systems.
