California building code requires infiltration testing for new homes, but no standard exists for multifamily buildings. Part of the reason is that they are difficult to test–a common method is to test the whole building at once, but this is expensive and complicated. An alternative called a compartmentalization test is conducted on individual units at a time. Compartmentalization testing advantages: units are safer in a fire, healthier because they inhibit the passage of smoke and smells between neighbors, and they make ventilation systems work better. The problem is it’s hard to get apartments tight. In this webinar we will review Steven Winter Associates’ database of over apartment 600 blower door tests and what we’ve learned from it. We’ll also review some recent work by the WCEC which is developing an automated sealing process to compartmentalize units.
