[Greenbuilding] first certified Passive House in Canada

[Ross Elliott]

Final air test was 0.57 ACH50.

 

Custom house prices depend on what you call "custom", I know people in the
country who can build you a custom shack for way less. Anyone have an idea
what tract homes go for on a SF basis? (the worst possible way to price a
house, I might add - people buy a small crappy house, then move up into a
bigger crappy house when their income goes up, rather than a better quality
small house).

 

Ground source heat pump was one of those things that could be termed
"inappropriate technology", sort of overkill for such an efficient house,
but seemed like a good idea back in the beginning (sure boosted that HOT2K
EnerGuide rating, even though it's somewhat about the same efficiency
burning coal in a power plant and sending it to a heat pump as just burning
the coal in the house for heat instead). No problems with building
inspectors to put XTPS under footings here in Ottawa, I think Chris used the
Celfort 600 but I've seen 400 used with no problems.

That's a pretty nice looking build Ross. Do you know what they came in as
for their final blower door test reading. I'm curious about Chris's
statement that to build a custom house in ottawa, you're looking at
225-250$/sq ft. Am I the only one that considers that to be somewhat of
reach of the average person.  

 

With their ground source system, were they able to find a unit that was
sized small enough to meet the low energy demands?

 

Very promising. Seems like they didn't have go too excessive on the subslab
insulation compared to some of the other cold climate projects I've seen. Do
you know if they had issues with the permit department with the foam under
footings.
