The use of glass and fenestration as part of the building enclosure material/system has become a significant consideration and component in today’s building design. Glass in a building enclosure is used as the medium that breaks down the visual/psychological barrier between the interior and exterior of a building. Glass introduces natural daylight into a space and provides views of the outside while it simultaneously keeps the forces of nature to the exterior.
An unbiased discussion and presentation of scenarios and criteria that are encountered when designing and installing roofing systems. The primary goal of this program is to introduce a way of thinking that will enable designers to select the proper system for the application and to become familiar with some of the more common roof system types used in the Northwest. This seminar is provided by Professional Roof Consultants, Inc. (PRC); a roofing, waterproofing and building envelope consulting firm located in Portland, Oregon.
Chris Benedict, using examples of her own work, will talk about the evolution of the system approach to building design and the profound position that the building enclosure holds as a part of that system. She will lay out her perspective on building enclosure fundamentals, including the management of air, water, vapor, light and heat and discuss how mechanical systems and materials can be refined, reduced or eliminated, while building performance is enhanced, when the relationships within the system are clearly understood.
This month’s presentation is a summary of a research study conducted by Walsh Construction Company and Building Science Corporation to evaluate highly insulated wood-framed walls for the Pacific Northwest. With changing energy codes, the 2030 Challenge and the need to reduce energy consumption, design teams and owners are considering exterior wall assemblies with ever-increasing amounts of insulation. The study evaluated exterior wall assemblies that provide a high insulating value while acknowledging the hygrothermal implications of increasing the insulating value.
Walsh Construction will be administering a whole building blower door test between 7 AM and 4 PM on Saturday. The building is located between Quimby and Raleigh and 13th and 14th. Please check in at the job trailer on Raleigh between 13th and 14th. If you wish to volunteer, please contact Marty Houston directly @ 503-5##-####.
This month Mark Campion will present information on the application of continuous insulation in walls per the 2010 Oregon Energy Code requirement.
This month our Portland BEC President, Dave Young, will present information on blistering in polyurethane membranes.
Water-filled blisters under cold-applied, asphalt-modified elastomeric polyurethane waterproofing membranes have been discovered on numerous buildings in the Pacific Northwest in recent years, often requiring replacement of the membrane. This presentation explains the phenomena of osmotic flow through polyurethane waterproofing membranes and presents strategies for addressing this problem through design.
The Portland BEC is hosting a local broadcast of this nationally sponsored webcast by BETEC/NIBS and AIA.
Portland BEC Members: free, plus BEC will submit your name for AIA CEU credits Non-members: $15 at the door Lunch will be provided for the first 30 attendees.

The first two BEC presentations for this year focus upon what project specific conditions warrant using an enclosure consultant and what conditions do not warrant inclusion of an enclosure consultant. The first panel discussion focuses more upon the working relationship setup and strategies, and the second panel discussion (October 2011) focuses more on the working management and roles.
