Scott Horowitz joined NREL in 2007 and manages the Residential Buildings Research Group's tools and analysis area, which includes work on whole-building energy modeling, cost-based optimization, model accuracy/calibration, and technology assessments. He is the lead developer of BEopt™, a residential building energy optimization tool used to provide support for the Building America Program's teams and energy efficiency goals, and a contributing developer to numerous software tools, modeling workflows, and data transfer standards, including Home Energy Score, ResStock, Energy Rating Index (ERI), Home Performance XML (HPXML), and Weatherization Assistant. Horowitz also leads efforts to incorporate residential models and capabilities into DOE's EnergyPlus™ and OpenStudio® platforms.
