That sounds amazing!  I hope you will tell us how it does in the winter, and maybe some 
photos?

    I knew I'd raise questions.
    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.
    Floor is 2200 Sq ft.
    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.
    No blower test as yet
    The house does rely on solar gain and shading. 3' overhangs on all sides.
    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)
    14' door/window combo in great room. Small solarium on south with approx 40 sq 
    ft of glazing
    Concrete floors throughout

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

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