Passive House Project Open House

10am to Noon

2 family wood frame retrofit in South Park Slope completed in 2011. Schuco windows, Zehnder ERV and dense pack cellulose insulation. This house was able to achieve an air-tightness of 2.0ACH at 50Pa but is expected to exceed Enerphit standards and actually meet Passive House requirement of 4.75 kbtu/sfyr.http://photos3.meetupstatic.com/photos/event/5/c/8/c/event_71003692.jpeg
