We have found that the amount of the grant for this kind of renovation by itself is likely to be quite small. One of our EnerGuide for Houses clients in Ottawa had almost exactly the same scenario, and after installing her new windows at a cost of $10,000, her home's rating improved by only one point - from 70 to 71 - not enough to qualify for any grant at all.

37. I'm replacing my 35-year-old windows with highly energy-efficient ones. What kind of difference will this make in the amount of the grant I will receive?
Recent case studies of houses in the Prairies have shown that the typical EnerGuide for Houses rating improvement is 3 points for an average 1960s house and 4 points for an average 1970s house. This data is consistent across Canada. The total grants in these cases ranged from $170 to $210.
The real value of replacing older windows with highly energy-efficient ones is the considerably improved comfort you'll notice when sitting beside the window. This is because energy-efficient windows have features (better air-seal construction with argon gas fill between the panes of glazing, insulated spacer bars between the panes and low-e coatings) that create a "warmer" surface. They're also often easier to maintain. Always ensure that replacement windows are properly installed to ensure minimum air leakage.更多精彩文章及讨论，请光临枫下论坛 rolia.net
