Certified RESNET HERS Raters play a central role in helping builders transition to new, more stringent residential building energy code requirements, like the 2012 or 2015 International Energy Conservation Code (IECC), which require blower door testing. Some builders have reported difficulty meeting new air tightness requirements such as 3 ACH50. Proper air sealing is critical to meeting these new air tightness targets and there are strategic locations that should be a focus for builders. The Insulation Institute has conducted research to quantify significant air leakage from five specific locations and estimated their potential contribution to ACH50 reductions. The research report can be downloaded at Five Priority Air Sealing Locations for New Homes. RESNET will be hosting a free webinar on August 16, 2018 at 2:00 p.m. Eastern on the findings of the Insulation Institute research. Learn where these five locations are and how raters can help builders target these locations to boost air tightness levels. The presenter of the webinar will be Charlie Haack, Director, Technical Services, NAIMA/Insulation Institute The webinar is free but one must preregister.
