“We were very impressed with Building Science Trust as well as Dan’s level of professionalism and knowledge surrounding our energy-related equipment. We had a Net-Zero plan done for our 1983 home and they set out a very detailed action plan, with step-by-step instructions to get us off carbon! We’ve slowly begun implementing measures and are starting to see the savings! We would not hesitate to recommend Building Science Trust if you’re looking to reduce your carbon footprint.”

– Steve Hubbard, Director of Business Development, Lightenco

“Dan Vivian from Building Science Trust did an energy audit and analysis of my house. The analysis includes a list of the options and costs of various energy saving measures available to me. The analysis is customized to my situation and takes into account specifics such as the age of my HVAC equipment. He then presented me with the options, listed in order of priority and return on investment. Overall it was a very good experience. I have already started working my way down the list.”

– Raymond Leury, President, Electric Vehicle Council of Ottawa
