The system will replace all of the indoor air every other hour while retaining about 96% of the interior temperature. The indoor air is kept fresh during the exchange with an UltimateAir energy recovery ventilator and a Fujitsu variable 0.25-1.0 ton 25-SEER mini-split on each floor.

The company is moving towards specializing in passive house construction and claims that it is able to keep costs to between $160 and $230 per square foot, which is no more expensive than typical US building costs.

Of course, a passive house costs much, much less to run over time, though, because it reduces the amount of energy needed to run it to a tiny fraction of what a typical US house takes to keep warm in winter and cool in summer.
