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. Some of the notable features and capabilities of EnergyPlus include:
- Integrated, simultaneous solution of thermal zone conditions and HVAC system response that does not assume that the HVAC system can meet zone loads and can simulate un-conditioned and under-conditioned spaces.
- Heat balance-based solution of radiant and convective effects that produce surface temperatures thermal comfort and condensation calculations.
- Sub-hourly, user-definable time steps for interaction between thermal zones and the environment; with * automatically varied time steps for interactions between thermal zones and HVAC systems. These allow EnergyPlus to model systems with fast dynamics while also trading off simulation speed for precision.
- Combined heat and mass transfer model that accounts for air movement between zones.
- Advanced fenestration models including controllable window blinds, electrochromic glazings, and layer-by-layer heat balances that calculate solar energy absorbed by window panes.
- Illuminance and glare calculations for reporting visual comfort and driving lighting controls.
- Component-based HVAC that supports both standard and novel system configurations.
- A large number of built-in HVAC and lighting control strategies and an extensible runtime scripting system for user-defined control.
- Functional Mockup Interface import and export for co-simulation with other engines.
- Standard summary and detailed output reports as well as user definable reports with selectable time-resolution from annual to sub-hourly, all with energy source multipliers.
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.
