In winter, our insulated floor slab (and living space) is warm. In summer  
it's cool.

No auxiliary heating in winter until late at night, if at all. No  
mechanical cooling in summer except for maybe 3 or 4 evenings during the  
Dog Days of summer.

Slab is exposed to direct gain in winter via equator-facing glass (no more  
than ~15% of floor area) and completely shaded from summer sun by  
appropriately-scaled overhangs. Super-insulated/air-tight construction.

Climate: ~8750 HDD/yr, which is frigid to some of you (but balmy to guys  
like Gordon in Edmonton Alberta)

Moral of the story ?  God and the Devil are in the details.
