The Science and Standards Behind Pearl SCORE^™.

Robin is a national expert on the valuation and financing of energy efficiency and home performance. In the mid-2010’s he co-founded a national non-profit, the National Home Performance Council, that developed strategies to bring residential energy efficiency to scale. He currently chairs the Building Performance Institute (BPI) Data and Modeling Standards and Technical Committee, and previously coordinated the development of multiple national energy efficiency standards, including the Home Performance XML (BPI-2100) and “Calibration” (BPI-2400) standards. He also launched and coordinated the National Energy Screening Project, a national initiative to improve utility cost-effectiveness screening practices.

Robin previously served as the Managing Director of the National Home Performance Council, a national non-profit created by the U.S. Department of Energy to develop policy solutions for scaling residential energy efficiency. He also served as the Executive Director of Hope Community, Inc. a New York City non-profit that built and managed over 1,200 units of affordable multifamily housing, and supported the Argentine Forensic Anthropology Team.

Robin holds a Ph.D. and M.A. in Anthropology for the New School for Social Research, a B.A. in Political Science and Anthropology from McGill University, and an International Baccalaureate from the United World College of the Adriatic.

After nearly ten years in the energy efficiency space and 30 in software development, AC Capehart has learned that understanding home performance is not all that different from understanding code: both are intricate systems of components that work together with complex interdynamics.

Previous experience includes stints at FireEye (cyber security), Perrone Robotics (vehicle autonomy), Linden Lab (Second Life), and Electronic Arts (games).

AC holds a Masters in Computer Science from the University of Virginia and a Bachelor of Arts from Swarthmore College.
