Expand The Modeling Capabilities Of DOE's Energyplus Building Energy Simulation Program

Report Number



Buildings; Simulation; Energy Efficiency


EnergyPlus is a new generation computer software analysis tool that has been developed, tested, and commercialized to support DOE's Building Technologies (BT) Program in terms of whole-building, component, and systems R&D. It is also being used to support evaluation and decision making of zero energy building (ZEB) energy efficiency and supply technologies during new building design and existing building retrofits. Version 1.0 of EnergyPlus was released in April 2001, followed by semiannual updated versions over the ensuing seven-year period. This report summarizes work performed by the University of Central Florida's Florida Solar Energy Center (UCF/FSEC) to expand the modeling capabilities of EnergyPlus. The project tasks involved implementing, testing, and documenting the following new features or enhancement of existing features: * A model for packaged terminal heat pumps * A model for gas engine-driven heat pumps with waste heat recovery * Proper modeling of window screens * Integrating and streamlining EnergyPlus air flow modeling capabilities * Comfort-based controls for cooling and heating systems * An improved model for microturbine power generation with heat recovery
