We tore down the house at 9805 - 84 Avenue about 45 days ago, and Peter Amerongen and Habitat Studios have made a lot of progress since.
The very beginning was quite stressful due to some difficult neighbour relations, but we go through that (for now). In the meantime, our foundation is poured and backfilled:
and the framing is well underway:
Adam the framer frames the double-walled exterior walls. Once filled with insulation and sealed, they will provide an amazing R56-rated resistance to heat flow to the outside.
The east and west walls completed, with a pile of reclaimed two-by-fours from the old pink house that Adam and Nick, the framers, will reuse as backing.
Rim detailing: Adam seals the gaps between boards to reduce air movement around the floor rim. This rim would normally remain exposed, leaking air for the entire lifetime of the house.
Adam finishes the rim detail by stapling a strip of Tyvek over the floor rim board. Attention to details like this, which Adam and Nick are very conscientious about, is very hard to come by in Alberta's slap-it-up-quick building industry trades culture.
The framing is probably the most revolutionary part of this NetZero Home, which is ironic because it adds the least amount of cost compared to the other innovations. Insulation and good sealing have no moving parts - they will save energy 24 hours per day, 365 days per year, and never break.
The second floor should be done by the end of this week!
