EnergyPlus and SketchUp – Integrating Building Energy Performance into Design

Thu, 14 Aug 2008 16:00:00 GMT

EnergyPlus—DOE’s building energy simulation program—includes many building energy-simulation features that previously have not been available together in a mainstream program. Features include variable time steps, configurable modular systems integrated with a heat balance-based zone simulation, on-site power, hybrid natural/mechanical ventilation, and under-floor air distribution (UFAD). The underlying heat balance load calculation method is included in the 2005 American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) Fundamentals. In 2007, DOE began working on a plug-in for Google’s SketchUp software, which Google describes as “3-D for everyone.” SketchUp is used by a majority of architects during early design to facilitate studies of shape and massing. The Energy Design Plug-In integrates EnergyPlus with SketchUp, allowing easy evaluation of building energy performance. This presentation, by Drury Crawley of EERE, introduces EnergyPlus and its simulation methodologies, capabilities, utilities, and interfaces that facilitate using it.

Drury B. Crawley is acting team leader for the Commercial Buildings area of DOE’s Office of Energy Efficiency and Renewable Energy. He leads DOE’s team that is working to achieve net-zero energy commercial buildings by 2025. He also is responsible for managing DOE’s building energy software tools research and development activities including EnergyPlus, Energy Design Plug-In, and DOE-2, among others. He has more than 30 years of experience in energy efficiency, renewable energy, and sustainability for buildings; and is active in ASHRAE, the U.S. Green Building Council, and the American Institute of Architects. He serves on the editorial boards of three international journals, has published more than 100 papers and articles, and has given more than 175 presentations throughout the world.
