Simergy v1.0 was released today. Simergy is a free graphical user interface (GUI)  that enables DOE’s whole-building energy modeling engine EnergyPlus to be used more easily and effectively. Simergy helps meet the advanced building energy modeling needs of architects, mechanical engineers, simulation consultants, energy analysts and sustainability consultants. Simergy can be downloaded from simergy.lbl.gov. (Note that the registration process is separate from the EnergyPlus registration process, though if you aren’t already registered for EnergyPlus, you can download it with Simergy.)
Simergy gives users access to the powerful modeling capabilities of EnergyPlus in an integrated energy-assessment workflow:

  • Support for multiple design alternatives.
  • Versatile geometry creation with 2-D and 3-D CAD import capabilities.
  • Libraries and templates of construction materials, default operating schedules, and HVAC equipment and templates for conventional and low-energy HVAC systems.
  • Drag-and-drop HVAC schematic editing that can be used to both customize standard templates and create innovative designs from scratch.
  • Customized summary reports and interactive visualization of simulation results at different levels of detail.

For more information on the capabilities of Simergy and EnergyPlus, please watch a series of video tutorials and explore the guides, samples, and FAQs available on the Simergy website.
