Almost 18 months ago we started down the path of making our home more energy efficient. Building science is the resident engineer's specialty so it’s been his mandate to improve the efficiency of our home in any way possible. I can’t even tell you how many cans of ‘great stuff’ foam we’ve gone through. We should have bought shares in it 18 months ago when we started sealing all the air leaks. It’s our style to take our time to do it right, so we used the entire 18 months allowed to complete all improvements as part of the government sponsored plan. Unfortunately the plan is no longer being offered for new audits. Perhaps more people were taking advantage of it then what was initially anticipated- and why wouldn’t you? Some of our improvements:
o Replaced 2 old windows with Energy Star rated windows
o Insulated 40% of our exterior wall space with spray foam
o Insulated our basement header space with spray foam
o Insulated our attic to R50 with blown-in cellulose
It may not seem like a lot but these 4 main improvements were good bang for the buck, resulting in almost $4000 in rebates. Now we just have to wait 12 weeks to receive the cheque in the mail....
