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!
