2021 2-Day Educational Symposium

The Portland Chapter of the International Institute of Building Enclosure Consultants (IIBEC Portland Chapter) invites all design professionals, consultants, and contractors practicing in the roofing, waterproofing and building enclosure fields to attend our 2021 2-Day Educational Symposium. We have invited some A-List presenters to come speak on a breadth of industry topics, and we’re sure you’ll go away with new insights and knowledge.  This year we’re offering both an in-person and virtual experience, and are offering discounted rates for multiple attendees from the same company (registered at the same time).  If you are attending virtually, a separate email, one week prior, will come with login information.  We look forward to having you join us!


Thursday Presentations Include:


How I Learned to Stop Worrying and Love the Downspouts

Presenter: Martin Houston, AIA, LEED AP

This presentation will study the historical development of gutters and downspouts as fundamental water management strategies in the built environment. We will discuss the growing trend of concealing water management tools such as gutters and downspouts and the risks inherent in such strategies. Finally, we will discuss how designers and builders around the world and over time celebrate these water managements strategies as a fundamental part of the design.

Martin Houston is a Principal at QEC, a Portland based enclosure consulting firm. Educated as an architect, Martin practiced for 14 years prior to joining Walsh Construction’s Quality team. He has been deeply engaged in building enclosure quality- focusing on durability and energy efficiency. Martin teaches the Building Enclosures class for architecture students at the University of Oregon.

Potential Issues with Application of WRBs

Presenter: Karl Schaack, PE

The long-term and optimum performance of WRBs relies significantly on the proper application of the system Overview of material options/selection.  Consequently, quite often issues are encountered during the installation of WRBs that have a significant impact of their performance.  The following topics will be reviewed:

  • Application methods or techniques.
  • Substrate types and preparation.
  • Transitions of construction materials.
  • Cladding installations.

Building Envelope Issues Museum of Tolerance, Israel

Presenter: Kenneth Klein, PE

The design of institutional buildings can push the limits of conventional construction in an attempt to create a landmark structure. For The Museum of Tolerance in Jerusalem, Israel, the architect designed a modern structure with the primary museum space below-grade and the exterior walls and roof clad with limestone. This design concept led to challenges in below-grade waterproofing, stone clad roofing, and flood control that have had to be remedied with construction modifications. This presentation will outline the original design and construction process of several key building envelope components and the remedies that were designed and installed to provide the Owner with the expected building performance and appearance.

Ken Klein has been with Simpson Gumpertz & Heger Inc. for over 36 years. He was previously the leader of the West Coast Building Technology division. He is experienced in the design and investigation of waterproofing of commercial, institutional, and residential buildings. Ken has consulted with architects, contractors, and building owners to analyze and repair water intrusion problems and construction defects. Well known in the industry, he has frequently presented to groups of attorneys, contractors, architects, and other design professional regarding building-envelope design and remediation issues. He is presently the Technical Advisor for the Western States Roofing Contractors Association.

Air Intrusion Conundrum – It makes a big “hygrothermal” difference, but how can we predict & control it?

Presenter: Phil Dregger, PE, RRC, Fellow-IIBEC

This presentation will review a three-year study involving a 450 unit HOA, with low-sloped highly reflective roofs, wood decks severely decayed in spots, in situ temp/RH loggers, roof moisture surveys, and coating the white roofs dark. WUFI Pro simulations will focus on selecting air infiltration models, selecting indoor climates based on temp/RH data, and selecting outdoor climates for design or forensic purposes.

Phil Dregger is a Professional Engineer, a Registered Roof Consultant, and has investigated roof problems for over 35 years. He has special expertise in wind, building codes, and condensation. Mr. Dregger has authored many articles on roof technology and has spoken to many industry groups. Phil received the ASTM D08 William C Cullen Award and the IIBEC/RCI Lifetime Achievement Award.

Friday Presentations Include:


Roof Jobs Gone Wrong – Small Changes, Big Problems

Presenter: Phil Dregger, PE, RRC, Fellow-IIBEC

This presentation examines roof projects where seemingly innocent changes led to problems. All of which, with the benefit of 20-20 hindsight, were avoidable. By the end of the presentation, attendees will be equipped, vicariously, with the “hindsight” needed to avoid problems related to four “avoidable” problems.

Moisture Durability in Green Standards

Presenter: Ben Meyer, AIA, NCARB, LEED AP

The requirements in green standards alone, such as LEED, Green Globes and IgCC may lack comprehensive measures to address resiliency related to the long-term performance of the building enclosure. We will review changes in codes, examples of roof and vertical assembly integrations, and tools to assess potential moisture challenges to enable energy-efficient and durable enclosure assemblies.
