Current Projects

Because the former developer from the DOE-2.1 and SPARK software, we’re now developing:

EnergyPlus logo

EnergyPlus

EnergyPlus is really 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 within structures.

Schematic from Modelica

Modelica

The Modelica Structures library is really a free open-source library with dynamic simulation models for building energy and control systems. We are developing this library to accelerate innovation resulting in cost-effective, really low-energy systems for brand new and existing structures.

Building Controls Virtual Test Bed

Your Building Controls Virtual Test Bed is definitely an open-source software atmosphere that enables users to couple different simulation programs for co-simulation, and also to couple these programs with actual hardware. For instance, the BCVTB can simulate an entire building in EnergyPlus and also the Heating and cooling and control system in Modelica while exchanging data backward and forward. It may also link these programs to building automation systems and also to databases for model-based operation.

GenOpt

Once an analyst has specified an issue for any computer simulation, there’s usually virtually no time to optimize the look by studying the extended procedure for different the input data, running the simulation and evaluating the different results. GenOpt, a normal optimization program, helps overcome a few of the challenges involved with using system simulation for analyzing complex engineering problems, particularly individuals associated with cost functions.

EnergyPlustoFMU

EnergyPlustoFMU may be used to export EnergyPlus data to some Functional Mockup Unit (FMU) for co-simulation. Analysts can model the envelope of the building in EnergyPlus, export the model being an FMU after which link that model by having an Heating and cooling system model coded in a method simulation tool for example Modelica.

Home Money Saver (HES)

Home Money Saver may be the web’s first do-it-yourself home energy audit tool. Huge numbers of people used it in order to save energy in your own home, while trimming energy bills and reducing green house gases. Home Money Saver was the produced through the Lawrence Berkeley National Laboratory for that U.S. United states doe. This project was backed through the American Recovery and Reinvestment Act (ARRA).

Commercial Building Money Saver (CBES)

Commercial Building Money Saver (CBES) is really a web-based energy retrofit analysis tool for small-to-medium-sized commercial structures in California. CBES provides energy benchmarking and three amounts of retrofit analysis thinking about the work goal, data availability, and consumer experience. CBES offers 82 energy conservation measures (ECMs) for lighting, envelope, plug-in equipment, Heating and cooling, and repair warm water retrofit upgrades. CBES uses OpenStudio and EnergyPlus to produce and run energy models.
