Energy Simulation Software


eQUEST –  is an hourly energy modelling tool using the DOE-2.2 simulation engine.  This is the primary software tool used by GreenSim.

Can-QUEST – download from Natural Resources Canada, is a Canadian adaptation of eQUEST which generates an NECB-2011 reference building model.

EE4 – obsolete software from Natural Resources Canada which generated the MNECB-1997 reference building.

Simergy – graphical interface for EnergyPlus version 8.1

OpenStudio – graphical interface for EnergyPlus version 8.4 using SketchUp as the model geometry tool.

RETScreen – a spreadsheet based tool for evaluating renewable energy technologies including wind, solar PV and solar thermal, run of river hydroelectric along with combined heat and power and energy conservation improvements.

These are the tools that we use most often at GreenSim but it is hardly an exhaustive list of energy simulation tools.  For a thorough directory of energy simulation tools have a look at IBPSA-USA’s BEST List.
