In direct connection to what's just been said, we worked on a pilot house in a community called Quaqtaq in Nunavik to try to achieve a passive house standard. The idea was to push the envelope and see what it would require. Was it possible, first, and then what would it require? As far north as it is, we have to deal with the weather, of course, the climate, which is extremely cold. That's the first stumbling block, but we did come across the same issues. We have a high-performing energy envelope, but the doors and windows were extremely expensive. Had they not been so expensive, we could have said that now all of the northern houses would be equipped with these top-of-the-line doors and windows, but they're not, because they're too expensive.
It's an ongoing innovation. If we manage to develop more performing insulation, thinner and more performing, that will certainly reduce the cost or bring the cost of a wall composition, roof, or floor to something that's reasonable. Right now our experience with this pilot house was that, in order to achieve a passive house, we had to have a massive wall, with massive insulation. We had to bring it down to something reasonable that could be built within a reasonable budget, but in the end, it was more expensive than your run of the mill.... We're almost there, but we're not quite there yet. There's no question that industry needs to be pushed, and I think that's where the federal government has to come on board to continue to maintain the work on these innovations.
