This presentation is for architects, engineers, and other design professionals interested in increasing their knowledge of the application and use of air barriers in existing building envelopes of commercial and multi-family residential buildings. Researchers, architects and code writers have shown that attention to specific details in both new and retrofitted envelopes results in better performing buildings with better comfort and long durability as well as lower energy consumption.

Learning Objectives:

1. How better building envelope can reduce energy demand on heating and cooling and reduce energy.
2. The significance of each part of the building envelope (the top, bottom, vertical shafts and the walls) relative to the efficient operation.
3.  What problems can occur with the lack of compartmentalization and/or decoupling between floors in buildings over 3 stories?
4. Discover the materials and methodology used in air sealing commercial and low to high rise multi-family buildings.
