Simergy v1.4 was released today. You can download it from the Simergy website at: http://Simergy.lbl.gov

Simergy is a BIM/BEM application that dramatically reduces the time and complexity required to use DOE’s whole-building energy modeling and performance simulation engine — EnergyPlus. Simergy was designed and developed to meet the advanced building energy modeling needs of architects, mechanical engineers, simulation consultants, energy analysts and sustainability consultants.
Long-Standing Simergy features include:
* Ability to manage and evaluate design alternatives
* Parametric building model creation with the Building Model Creator™
* Libraries of construction materials, building elements, solar shading, schedules, and HVAC equipment, controllers, and sensors.
* Time-saving templates for both conventional and low-energy HVAC systems, daylighting controls, natural ventilation, zone loads, zone conditions, simulation configuration, and simulation results
* Drag-and-drop HVAC schematic editing that can be used to both customize standard templates and to create innovative HVAC designs from scratch
* Customized summary reports and interactive results visualization that allow simulation results explored individually, at different levels of detail, and across multiple design alternatives
Improvements in this version:
* Performance improvements
* Improved crash reporting
* Improved Building Model Creator™
* Various bug fixes
New Features coming in a Professional version (now in Beta Testing):
* Support for EnergyPlus v8
* 2D to 3D tools for converting drawings into building models
* Import of building models from industry leading design applications (IFC/gbXML formats)
* Improved building model creation tools (including DWG Draw-Over)
* Import of nearly all IDF objects
* Automatic diagramming of HVAC systems imported in IDF format
* Support for Dual and Triple-duct air loops
* Support for primary/secondary water loops
* Support for Steam loops
* Support for Variable Refrigerant Flow (VRF) equipment
* Support for Thermal Storage
