EnergyPlus is a whole building energy simulation program that engineers, architects, and researchers use to model both energy consumption-for heating, cooling, ventilation, lighting and plug and process loads -and water use in buildings.

OpenStudio is a suite of free and open-source software applications for building energy analysis used in building information modeling. OpenStudio applications run on Microsoft Windows, Macintosh, and Linux platforms. Its primary application is a plugin for proprietary SketchUp, that enables engineers to view and edit 3D models for EnergyPlus simulation software.
OpenStudio was first released in April 2008 by the National Renewable Energy Laboratory, a part of the U.S. Department of Energy. NREL reports an average of 700 OpenStudio downloads per month.[8] Google's strategist for SketchUp, remarked that "OpenStudio is lauded around our office as one of the most complicated plug-ins ever written for SketchUp".
OpenStudio was designed to work with SketchUp, because many architects already use SketchUp for building designs. The integration allows architects to analyze a design's energy performance before beginning construction.
