Addressing Condensation in Low-Slope Roof Assemblies In basic roofing design, vapor retarders and air barriers play a crucial role in reducing air leakage and enhancing the performance of the roof system. However, their benefits extend beyond simple air sealing. This course explores the impact of new innovative technologies, including permeable vapor retarders and air barriers, […]

Sustainable Building Envelope Performance with Self-Sealing Fasteners & Anchors 1.0 IIBEC credit and 1.0 GBCI credit Sustainable building envelopes demand high performance from and proper installation of continuous insulation and air, water, and vapor control layers. What happens when thousands of holes are made in these materials as they are installed with blind fasteners, one […]

Path to Net Zero: Beyond Handing Over the Keys Net Zero is not a pass/fail scenario. We are designing our buildings to be able to make a net positive outcome, but if the true operational impacts are not baked into the design are these buildings being set up for failure? Do we have the opportunity […]

NIST Clearing House for Infiltration Modeling Purposes (CHIMP) Infiltration is the unintended and uncontrolled air leaking into a building through intentional and unintentional openings. While infiltration has been used to fulfill outdoor air requirements in buildings, it is not generally accepted as a “best practice” anymore. But how much infiltration can you expect in a […]

 Case Study on ICF Panel Waterproofing Failures This is a case study on Construction Defects in a $1.3 million new home built with insulated concrete forms (aka ICF panels). ICF is becoming increasingly popular for custom homes and DIYers, but many details are hard to find, and many trades are unfamiliar with their unique requirements. […]
