Jon joined NREL in 2009 and works in the Building Energy Science group. Jon’s area of expertise is residential heating, ventilating, and air-conditioning systems (HVAC), including installation quality, cold-climate heat pumps, dehumidification systems, high-performance home cooling loads, occupant thermal comfort, and building energy modeling.

Prior to working at NREL, Jon was a faculty research assistant in the Mechanical Engineering Department at the University of Maryland, where he co-led the development effort of vapor compression system simulation and optimization software used by HVAC manufacturers.
