The frame of a Passivhaus may not be as exciting as the thick layers of insulation, the high-tech mechanical systems, or the triple-glazed windows, but it plays a very important supporting role in achieving success. Every component of the framing package in this house was chosen with care and for a specific reason. The exterior Zip System sheathing provides airtightness, the double-stud walls and raised-heel roof trusses are a cost-effective means of supporting or containing above-average levels of insulation, and the open-web floor trusses easily span the open floor plan and provide plenty of room for the many ducts necessary for the Zehnder ventilation system and supporting mechanicals.
