Research Summary
Advanced thermal energy conversion systems, energy utilization in buildings, and the interactions between a building and its environment. Specifically include the development of advanced, highly integrated, heating, ventilating, air conditioning, and refrigeration systems; the role of renewable distributed power generation and combined heat and power (CHP) systems in residential and commercial buildings; and the integration of these technologies into high performance buildings
