Before taking this class, you should have completed “Building Science Principles and Practice 1: Overview and Introduction to Control Layers” or an earlier version of that class titled “Building Science Principles and Practice for Nonresidential and Highrise Residential Enclosures”.
Moisture comes in several forms, all of which need to be managed to achieve a durable, healthy building. Warm air has greater moisture-carrying capability than cooler air, but when warm air comes in contact with cool surfaces condensation occurs. Lack of continuity of thermal and air control layers, as well as inappropriate vapor control, can enable condensation in a building assembly. This on-demand program focuses on condensation moisture and how to avoid condensation-related problems like mold and rot in your wall and roof assemblies. Dr. John Straube provides a clear introduction to concepts like dew point and relative humidity. He also goes further to discuss different surface responses to condensation, the role of dehumidification and air conditioning, and more.
