Our results for heat loss were no surprise to us. Out of a rating of 50 (lower number= more energy effecient), the basement is rated at 49 (there was no insulation at all), air leakage and ventilation at 41, the main walls at 40, windows at 38 and ceiling (attic) at 8. The next step is to see what's financially possible, i.e. small investment= big return. With the windows being currently rated at 38 and improving to 9 (after installing all new windows with double glazing, argon stuff, etc.) and it costing a fortune to replace, we probably won't be doing that improvement... although we will be replacing the front windows.... eventually. The basement is the easy one to bring down to their suggested 13 (from 49). We've already started insulating and putting up vapour barrier (dont' worry, it's in the next post), and for the heating... well, you've already met Slim... which was a huge incentive to get the evaluation in the first place.
In our results there's also a chart that shows the energy use for the heating system in gigajoules (GJ). They estimated that The Beast used 180GJ of energy to run. If all the upgrades they've suggested are implemented, the energy usage drops quite dramatically to 50GJ. Now that's energy saving! Too bad windows cost so freakin' much!
Once everything is updated, insulated, spray foamed and weather sealed, we'll be calling back our friendly energy advisor and aksing him to bring his big yellow fan to see how close we came to their suggested rating of 75.

That is the neatest!
