[Greenbuilding] first certified Passive House in Canada

[John O'Brien]

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.
