No matter how long you’ve been a building practitioner, you never stop encountering building science head-scratchers. Assemblies that you thought you had meticulously detailed may leak. Materials that you thought would last decades may show signs of pre-mature failure. Systems that seem like they should work (or have worked in the past) don’t. This workshop will teach you how to identify, diagnose and solve building science puzzles for a variety of building types, including residential, commercial and institutional, constructed using both traditional and modern methods. The presenters will share a series of case studies and invite the group to work together to identify the problems and propose solutions. Participants will also have an opportunity to present their own puzzles for group discussion.
