We have two new Passive projects in construction now, “Acorn Glaede” in Downers Grove, and a not-yet-named house in Hinsdale. They both started in the summer; Downers is a slab-on-grade, but Hinsdale has a full basement. Here are some compare-and-contrast images, starting with Hinsdale (we didn’t get to the site before framing started):

on PHIUS tour–basement at Hinsdale; note 8″ EPS outside exposed concrete foundation


The Architect considers the foundation-wall joint


2×6 framing with Zip sheathing as airtight layer, 5.25″ EPS outboard, flush with exterior face of 2×12 bucks


South facade–seen from alley, garage to left begun


From northwest


East facade–the “modern farmhouse” look taking shape


Using Rosboro X-Beams: no-added formaldehyde glulams

Now for Downers Grove:

Frost-depth foundation with 8″ exterior, 4″ interior EPS; note separation of exterior porch with insulation–no thermal bridge


Closeup of corner


Slab poured, StegoWrap in place


Tom with initial color studies for prefinished color-mix on LP SmartSide siding


Walls going up! 2×6 wall framing; note 2×12 bucks at openings, like Hinsdale…a favorite detail


Second floor walls–that oak tree behind was a major driver of plan layout


View from Living Room through south windows to the other great oak tree


With owner and her parents…


Big bucks on the east wall


Capped out before the cold hit!

That’s it for now–more to come as these get enclosed and finished!
