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.
