    • Evaluation of Crawlspace Retrofits in Multifamily Buildings

    Metadata Updated: November 2, 2023

    In 2011 and early 2012, Building Science Corporation (BSC) collaborated with Innova Services Corporation on a multifamily community un-vented crawlspace retrofit project at Oakwood Gardens in Lansdale, Pennsylvania. BSC provided design consulting services and pre- and post-retrofit evaluation, testing, and data monitoring.The existing condition was a vented crawlspace with an un-insulated floor between the crawlspace and the dwelling units above. The crawlspace was therefore a critically weak link in the building enclosure and was ripe for improvement. Saving energy was the primary interest and goal, but the greatest challenge in this un-vented crawlspace retrofit project was working through a crawlspace bulk water intrusion problem caused by inadequate site drainage, window well drainage, foundation wall drainage, and a rising water table during rainy periods.While the un-vented crawlspace retrofit was effective in reducing heat loss, and the majority of the bulk water drainage problems had been resolved, the important finding was that some of the wood joists embedded in masonry pockets behind the brick veneer were showing signs of moisture damage.
