Yeah, i got their data for Hamilton and ran the numbers with it, and the results just seemed too good to be true. I checked the data to some degree with NASA, i'm still looking to cross-reference it more that way. Then i ran the numbers again with the data above, and percent sunshine figures for Toronto supplied by Kachadorian's book. Calculated that way, the incoming sun was way lower. I still have to compensate for the fact this chart only gives figures for vertical glazing, but the NRC values were a full 40% higher. Just a huge difference.
