General Information

The Portland Building Enclosure Council is pleased to announce the 2018 Technology Symposium. This year’s Symposium will focus on durability issues affecting the Building Enclosure.

The symposium is a one-day event, comprised of presentations, speakers, and opportunities for sidebar conversations. The conference will bring together leading code knowledge from Canada and the United States focusing on existing and future building enclosures. The academic knowledge will be complimented by real world applications and case studies

  • Meet with the local representatives of leading building product manufacturers
  • This all day event includes continental breakfast and seated lunch.
  • 6 AIA /CEU - LU/HSW expected

Speakers & Sessions

Catherine Houska
Session 1 - Metal Selection and Design for Longevity

With increased emphasis on whole building life cycle assessment, owners increasingly want materials and systems that can provide longevity. Accurate prediction requires both assessment of the site and an understanding of materials. Even project locations in relatively close proximity can vary significantly in their exposure to corrosive pollution, coastal or deicing salt, moisture exposure and other factors that can affect deterioration. Design elements like sheltering, crevices, metal combinations and finish roughness also affect performance. Case studies will be used to illustrate the fundamentals of site assessment and comparative corrosion data for metals will be provided. Galvanic and other types of corrosion that can affect performance will be reviewed. Some common misconceptions will be reviewed.

Mike Dutton
Session 2 - Curtainwall Loads and Testing

Presentation will cover environmental loading considerations including wind and seismic. The upcoming code will adopt the load design document ASCE 7-16 which has changes to both seismic and wind that will impact curtainwall. Effects will be reviewed so expectations can be adjusted. The presentation will also include structural considerations for performance mock up testing from testing standards AAMA 501.4 and 501.6 and the difference between these two tests and when to use them. In particular building drifts will be reviewed in detail as they pertain to curtainwall design.

Andre Desjarlais
Session 3 - Envelope Air Leakage Tools

Buildings account for more primary energy consumption in the United States than both industry and transportation. Building energy-efficiency measures have enormous potential to reduce energy consumption, costs, and greenhouse gas (GHG) emissions. Progress can be made by installing commercially available technologies like ENERGY STAR* equipment; however, technology innovations are required to meet future energy efficiency targets. The US Department of Energy’s Windows and Building Envelope R&D ET Roadmap, published in 2014, identifies research opportunities for improving the energy efficiency and durability of new and retrofit residential and commercial buildings to meet DOE’s goal of a 50 percent reduction in building energy consumption by 2030. The findings of this report have served as a launching pad for the research activities that are now underway at the Oak Ridge National Laboratory’s Building Envelope Systems Research Group.

Robert Lepage
Session 4 - Biodeterioration and Buildings

Humans have been using wood to build structures for thousands of years. More recently, mass timber and engineered wood are promising structural materials finding greater acceptance within the building industry, particularly in novel applications, such as Tall wood buildings. With greater exposure however, comes greater risk. Delving into the building physics, we will explore the micro and macro conditions suitable for biodeterioration, the mechanisms of degradation, available tools to assess and identify risk, as well as conceptual level recommendations to ensure acceptable building performance throughout its design service life.

David Nicastro
Session 5 - Durability as a Factor in Construction Litigation

Problems with manufacturing, design, and construction cause countless premature failures of water-resistive barriers; therefore, durability is a central factor in construction litigation. This presentation will synthesize a practical understanding of durability based on theoretical behavior, observations from numerous failure case studies, and research and test results from The Durability Lab. Improving durability is also closely related to sustainability; preventing premature failure keeps building materials out of the landfill longer.

Mike Steffen
Session 6 - Orchards at Orenco - Measured Performance

This presentation will discuss the measured performance of the Orchards at Orenco affordable housing project in Hillsboro, Oregon. With 115 units already completed, and a third phase currently under construction, this project is the largest Passive House certified development in North America. Mike Steffen of Walsh Construction Co. will describe the integrated design and construction process used during the first two phases of the Orchards project, the systems used and key details, and will discuss the lessons learned, including how the cost premium to achieve Passive House was reduced significantly during the second phase. Mike will also share detailed feedback on the building’s measured energy performance and discuss the results of extensive monitoring studies of the enclosure system used on Phase I. This presentation will provide valuable information and insight regarding how to deliver high performance, low energy housing to communities across the Pacific Northwest.
