Olivia gives a guided eco-retrofit tour of her house

Thank you for posting/hosting this video. Wouldn't it be great if Canadians' penchant for home renovations always included such innovative retrofitting?

Indeed!

There are other interesting technologies out there, and some of them are quite low-cost. There are also things that tenants can do (as I am, and am not in the position to renovate), such as sealing cracks near windows, and weatherproofing doors. My landlords were around today, and I've arranged this for our house.
