Dr. William M. Healy

Dr. William M. Healy is the leader of and a supervisory mechanical engineer in the Heat Transfer and Alternative Energy Systems Group of the Energy and Environment Division (EED) of the Engineering Laboratory (EL) at the National Institute of Standards and Technology (NIST). Dr. Healy joined the Heat Transfer and Alternative Energy Systems Group in March 1999 and assumed the duties of Group Leader in 2007. He manages the Net-Zero Energy, High-Performance Buildings Program within the EL Strategic Goal of Sustainable and Energy-Efficient Manufacturing, Materials, and Infrastructure. His current research interests involve the development of metrics to assess the performance of wireless sensors in buildings, the development of improved tools for residential energy measurement, and the development of improved test methods for rating the performance of residential water heaters. Dr. Healy has also investigated improved sensing methods for determining the moisture content within building envelopes. As a result of this effort, he and his collaborators were awarded a patent on the use of ultra-wideband radar to map the moisture state of a wall. Additional efforts have included support of the guarded hot plate development through finite element modeling and participation in efforts by the Department of Homeland Security to develop the infrastructure to allow data from sensors to be propagated to applications that require knowledge of hazard levels. Dr. Healy is a member of the American Society of Mechanical Engineers (ASME) and the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE). He currently serves on ASHRAE TC 7.5: Smart Building Systems and as a voting member for ASHRAE Standard Project Committee 118.2: Method of Test for Rating Residential Water Heaters. He has previously served as a voting member on ASHRAE TC 4.4: Building Materials and Building Envelope Performance. He is also an instructor in the Johns Hopkins University Engineering for Professionals program, where he teaches courses in Applied Heat Transfer and Thermal Systems.
