Dynamic Interfaces of Water-Resistive Barriers

Maggiano's Little Italy, 516 North Clark Street, Chicago

The Chicago chapter of the Construction Specifications Institute invites you to its annual building enclosure event.

Water-Resistive Barriers (WRBs) have evolved to serve compound forms and functions. Despite these advances, performance expectations still reflect over-simplistic assumptions and problematic testing methods. Interfaces with modern wall components also remain ill-defined with respect to the WRB’s primary function of liquid water resistance. Industry trends toward component integration have further strained the WRB’s intended role. This two-hour presentation will review new findings from experimental research and computational modeling to demonstrate performance attributes of recognized WRB systems. Moisture transport and storage will be reviewed for three dynamic interfaces: (a) the exterior insulation interface; (b) the substrate interface; and (c) the fastener interface. Directives for industry research, testing standards, and product innovation will be discussed. 

Speaker: M. Steven Doggett, Ph.D., LEED AP, is the Principal Scientist and founder of Built Environments, Inc., an architectural & building science consulting firm specializing in building enclosure design and research. His background includes extensive field experience with complex building enclosure failures, particularly those involving air, heat, and moisture transport.  He merges this experience with innovative design practices to assist multi-stakeholders achieve more resilient, higher-performing buildings.  Dr. Doggett is actively engaged in enclosure design, assembly and material research, and building simulations involving computational fluid dynamics, 3-D thermal modeling, and hygrothermal modeling. Dr. Doggett is the former chair of the Minnesota Building Enclosure Council.
