Footings

In many cases, we’re trying to use fairly conventional construction techniques. However, the house foundation requires special treatment, as most houses lose significant amounts of heat to the ground. To achieve Passive House, insulation around and below the entire foundation is essentially required. Our details call for a 12″ thick strip of geotechnical-grade EPS insulation beneath the footings (min. 100kPa bearing capacity).

This is the angled corner at the south corner of the house. Both floors will feature large 10’x6′ window openings to capture as much southern solar radiation in the winter months, with relatively deep overhangs to prevent overheating in the summer.

Footings complete! The pad footing at the center is the only other structural support for the house, minimizing any chance for unfortunate thermal bridges into the ground…
