As an instructor of realtors across Ontario, I can say with absolute confidence that Ontarians who are doing the right thing for themselves and the environment have not seen the real estate industry being effective at putting a value on home energy efficiency. In the last year I have spoken to roughly 3,000 realtors in training contexts. Every time I teach a course, I ask people to put their hands up: “Who has sold a house with a geothermal heating system?” I ask those same folks to tell me, “Who has received a premium from the marketplace?” I then ask what was the reason that they did not, because the consistent answer was they did not. The reason that they did not was because the buyer market does not understand energy performance.
