[Greenbuilding] apples, oranges, and u values

[KTOT (g)]

I haven't been following this thread (have been out of town) but my year-old 
off-grid, passive house with low-e Weathershield windows and very excellent 
spray-in insulation (and extremely tight all around) performs magnificently. 
In this cold northern Rockies winter at almost 6000 foot elevation, the 
house was heated almost entirely by passive solar, with solar thermal 
radiant providing the heat the rest of the time, my backup Rinnai almost 
never kicking on at all. I never used the wood stove for heat as the house 
stayed warm enough without it. The low-E windows had two different values, 
something like 176 and 273 (not quite those, I'm sure), but I'd have to look 
those up in my records to be correct on the types of low-E.
