More Building a Net-Positive House
BPC Green Builders project manager Ben Bogie explains how double-stud walls help meet the energy performance goals of this net-positive home being built in Upstate New York. He also talks about the attributes that make this his go-to assembly, including its familiar framing for carpenters, extra-deep insulation cavity, and inherent thermal break. We see ZIP System sheathing being installed and learn why it was used as the primary air barrier.

Enjoying this series quite a lot. What made you all decide to go with Zip over something with more perms, like Plywood and adhered WRB?
Acf -spot on - The question answers itself .of course plywood and say Vaproshield Canfield a very vapor permeable wall, the WRB barrier is not a microscopic sheet of paper impregnated with resin, flashing of window rough openings rough openings superior, AND you now have to worry less if water does penetrate the wall assembly - zip is, after all, osb…unfair to expect Ben to respond because the answer is clear.
I am also truly enjoying this series, and would like to learn more about the above question.

So well done, great work everyone!
@Ben, what was the thin strip over-layer on top of the EPDM bulb sill seal, an aluminum sheet termite barrier?
