This page was developed by the Queen's University Applied Sustainability Research Group.

Abstract

This page is intended to be used as a resource for selecting building energy modeling software solutions. Most software packages perform very specific tasks, suggesting that a number of different packages be used to obtain accurate results for a desired project. Not all software packages are free of charge, but often demos may be obtained. Please refer to each package's corresponding link for more information.
