Earlier this summer we started construction on a Passive House in Mountain Lake Park. The home was designed for a local couple who have had their heart set on building a sustainable home for years.  The owners began working with Carri Beer, AIA, LEED AP, from Brennan and Company Architects, and Passive House consultant Michael Hindle. 

The Passive House has many energy efficient and sustainable details.  Below are some photos of the excavation, foundation, and footing insulation.  

The footings bear on a cellular glass insulation block called FOAMGLAS from Pittsburgh corning, and the under slab, interior and exterior of the footings have Roxul Rockboard mineral wool insulation.
