Building professionals use software to assess the energy performance of buildings after renovation. Differences were observed between the results from different software.
This report from a study operated by CSTB within the French program RAGE 2012 analyses several available software for the calculation of the energy performance of residential buildings.
Test cases (houses, dwellings) have been studied with the following tools: Bati Cube, Cap Energy, Easy Energie, Orebat, Pro Eval, Pro Expert MI.
For each software, information is given about its field of use, ergonomics, reliability of results and precautions that should be taken when using it.
