The control of air infiltration and exfiltration is becoming increasingly important for modern energy-efficient buildings. This course presents the arguments for airtightness in buildings and how to detail air-barrier systems. Because airtightness is a “whole building” characteristic that depends on the work of multiple trades, we will also look at commissioning and inspection during construction. You will come away with a stronger understanding of how air-barrier systems work and how to solve common problems in design and construction.
