Blower Door Testing

摘要

Air leaks in houses are a big problem. Leaks make homes uncomfortable and expensive to heat and cool. They create condensing cold spots that attract mold and rot. They lead to frozen pipes and make homes less resilient during prolonged power outages. Dealing with air leaks starts with locating them. There are many ways to find air leaks; the easiest and most common is to use a blower door. Blower-door tests used to be the exclusive domain of weatherization workers and building-science geeks, but that's not the case anymore. Everyone involved in residential building needs to become more familiar with blower-door testing because universal testing for all new homes is coming.
