Repost: OBC Stop the Foot Dragging on Air Leakage Testing
Our friends over at Blue Green Group made a post recently that highlighted how air leakage in high performance homes should be more closely integrated into the Ontario Building Code’s SB-12 Section, as well as how more training amongst professionals and builders is needed to implement already existing technology and techniques for air tightness. See below for an excerpt and check out the full post here.
Waiting for the Building Code to incrementally ratchet up efficiency every 5 year cycle is too long a wait for high performance housing. The new 2017 version of SB-12 still has a prescriptive package (A1) that merely permits a fiber insulated 2×6 stud wall cavity without air leakage testing – that’s so 1980′s! We’ve had the materials and building science know-how since the 70’s, and with the proven processes of the Passive House approach to designing and building the most efficient buildings, there’s no excuse for not building high performance homes – now.
