HAP, Trace and BeOpt are using EnergyPlus now as the simulation engine. The list is more apple to apple to include IES VE, IDA ICE, DeST, ESP-r.

While I haven’t worked with all the tools on your list I highly recommend EnergyPlus. It’s very robust and commonly used in the building science field. Plus, you can find many models of typical “archetype” buildings already developed and calibrated for the US building stock (see: https://www.energy.gov/eere/buildings/commercial-reference-buildings). Those could be a good starting point.

Dear Dr. Hafiz Zafar Sharif,

I suggest you to have a look at the following, interesting note by Robert Fassbender on “What is the Best Energy Modeling Software” (2015) available at: http://energy-models.com/blog/what-best-energy-modeling-software.

You can also see at the following previous questions on Rg at:

and

Thanks to everyone for your kind response about the my query.

It depends on the objective of the modeling.

If you are looking for a free, open source platform, EnergyPlus is a good idea. BEopt is more suitable for residential modeling. Another software that is quite complete is DesignBuilder, but you have to buy it...

Hi

Design builder is a good software.

HAP, Trace and BeOpt are using EnergyPlus now as the simulation engine. The list is more apple to apple to include IES VE, IDA ICE, DeST, ESP-r.
