We have been helping Canada build better homes for over 30 years, founded by building science pioneer Bruce Gough. Licensed architect, Mark Rosen, started with Building Energy in 2008 to gain an appreciation and understanding of the way houses are put together. Starting out as a site inspector, he is now the owner, and has helped develop software tools, sits on several advisory boards and continues to actively lead the industry towards positive change. We  now certify over 900 homes in the Ottawa-area per year.
