<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">I knew I'd raise questions.<br>
I am in Napanee, Ontario (SW of Kingston). HDD annually is 4311; CDD is 215. These stats are from the Weather Network. The HDD is quite a bit higher than EnCan's estimates for Kingston, so I don't know how accurate they may be.<br>
Floor is 2200 Sq ft.<br>
I don't have cooling, and the heat is tied to the dryer and DHW and stove. I am trying to calculate summer usage to give me a rough idea of the winter heat load.<br>
No blower test as yet<br>
The house does rely on solar gain and shading. 3' overhangs on all sides.<br>
Windows calculated at 13% of wall area. Most are south facing (only 30sq ft of windows on north wall) Windows were 'tuned' to the exposure by Thermotech)<br>
14' door/window combo in great room. Small solarium on south with approx 40 sq ft of glazing<br>
Concrete floors throughout<br>

Congrats on the house. One hundred questions come to mind. Such as:<br>
What region are you?<br>
What are the average HDD's and CDD's for your location?<br>
What is the floor area of the house?<br>
Can you isolate the KW's and or BTU's used for heating and cooling for given periods?<br>
Did you do a blower door test on the house after completion? Do you use heat recovery ventilation?<br>
Does the house rely on solar heat gain and or solar shading? Any other consideration of window location and solar exposure?<br>
What sort of glazing did you use?<br>
<br>

Since I get tremendous information from the folks on this list, I<br>
thought I'd share what has transpired so far on my house, in the<br>
hope it helps others.<br>
<br>
House is Durisol, R28, plus 2" of closed cell soy foam on outside.<br>
Slab on grade with 5ft frost wall underneath. North wall bermed<br>
to 5'. Windows are Thermotech. 2200 square feet.<br>
Overall: R42 in walls, R34 under slab, R65 in ceiling.<br>
LED lights (mostly from IKEA) in many areas, CFLs in many. 2<br>
Halogens, bought when the salesperson promised that the GU10 CFLs<br>
would fit in the fixture. They did not, so both are on dimmers<br>
and will be replaced when the budget allows.<br>
HeatKit masonry heater; propane fired radiant in floor (Rinnai on<br>
demand system).<br>
Propane stove and dryer<br>
No waste hot water recovery system, as virtually all drains are<br>
embedded in floor.<br>
Outer taps fed by cistern, run by jet pump as needed. Jet pump<br>
will eventually run on solar.<br>
<br>
Performance:<br>
<br>
95-98F degree heat last week, for several days. Minimal wind<br>
Interior temp never higher than 75F.<br>
Hydro (electricity) bills past two months <$70/month, even when<br>
running table saw, mitre saw and concrete mixer, in addition to<br>
home office equipment.<br>
I can't gauge propane consumption yet, as the tank won't be<br>
refilled until the fall.<br>
<br>
FWIW!<br>
<br>
Thanks again for all the information you've given me.<br>
