Tuesday Event Speaker

The Impact of Air Intrusion on Mechanically-Attached Roofing Systems
It has been suggested that cool roofs with mechanically-attached membranes pose a greater risk to moisture durability (i.e., a risk of intermediate condensation underneath the surface membrane) than roofing systems with traditional dark surface colors, primarily because of air intrusion. Since there is usually a high temperature gradient between the indoor environment and the roof surface, conditioned indoor air pulled to the interior side of the roof membrane will be very much affected by the exterior roof surface temperature; therefore, air intrusion causes an energy penalty as well. In this presentation, the moisture durability and expected energy loss is evaluated analytically based on variations in outdoor climate, roof surface color, and the air permeability of the roof materials underneath the surface membrane.

André Desjarlais is the Program Manager for the Building Envelope and Urban Systems Research Program at the Oak Ridge National Laboratory. He has been involved in building envelope and materials research for over 40 years, first as a consultant and, for the last 25 years, at ORNL. Areas of expertise include building envelope and material energy efficiency, moisture control, and durability. Desjarlais has been a Member of American Society for Testing and Materials (ASTM) since 1987 and serves on Committees C16 on Thermal Insulation and D08 on Roofing. He is the past Chairman of ASTM Committee C16 and was awarded the title of Fellow in 2011. He has served as the chairman of ASTM’s committee on Technical Committee Operations (COTCO). He has been a member of ASHRAE since 1991 and serves on Technical Committees TC 4.4 on Thermal Insulation and Building Systems, TC 1.8 on Mechanical Insulation Systems, and TC 1.12 on Moisture Control in Buildings, and is past Chairman of TC 4.4. André is also a founding director of the RCI Foundation.
