ETA researchers develop whole-building energy simulation software programs that allow architects and building engineers to design or retrofit buildings for maximum energy efficiency and occupant comfort.
Programs developed by ETA researchers include the following:
- EnergyPlus whole-building simulation program
- Modelica Buildings library for rapid prototyping and controls design
- Building Controls Virtual Test Bed for co-simulation and for model-based operation
- GenOpt generic optimization program
- EnergyPlusToFMU to export EnergyPlus as a Functional Mock-up Unit for co-simulation.
- CBES (http://cbes.lbl.gov) Web-based application for commercial building energy retrofit analysis
- CityBES (https://citybes.lbl.gov/) Web-based data and computing platform for city scale building energy efficiency
- Occupancy Simulator (http://occupancysimulator.lbl.gov) Web-based application for simulation of occupant presence and movement in buildings
The Simulation Research Group is leading, with RWTH Aachen, the International Energy Agency's Annex 60, which is developing new-generation computational tools for building and community energy systems based on the Modelica and Functional Mockup Interface standards.
The Simulation Research Group is also leading, with Tsinghua University, China, the IEA EBC Annex 66 (https://annex66.org): definition and simulation of occupant behavior in buildings. Our behavior research (https://behavior.lbl.gov) focuses on energy-related occupant behavior, using advanced data analytics, modeling and simulation, to reduce energy sue in building and improve occupant comfort.
