Portland BEC Sustainability in the Building Envelope

Fluid applied membranes, whether as a flashing or as a weather resistive barrier, are becoming much more common in the marketplace. This presentation will discuss the history and development of fluid applied membranes and will give attendees an understanding of the various different chemistry types available in the market; why they were developed and the important performance characteristics, including the advantages and disadvantages of each different chemistry type. Finally, attendees will understand how to choose the appropriate material for different applications and how to design with each material.

After 34 years at a major Silicone Sealant company, Dave Kimball has retired and started anew with PROSOCO, Inc., as a Technical Specialist in the Building Envelope Group, covering the North Atlantic Region from his office in Brooklyn, NY.

While Dave spent years living in many different parts of the country, primarily in a Technical Service role, working on Weatherseal, Structural Glazing, and exterior coatings applications, the unique challenge that rough opening preparation and Air and Vapor Barriers brings is inspiring.

In this course the presenter will discuss current research and understanding of moisture related problems within sloped roof attics in the Pacific Northwest. Case studies will be presented to illustrate the possible wetting sources in wood-frame construction along with practical solutions for mitigating the potential for problems in new construction.

Lorne Ricketts is a building science engineer specializing in research and investigation work. His experience consists of a wide range of projects including: building enclosure condition assessments, forensic investigations, building monitoring, field review, building modeling, and laboratory and field testing services.

Lorne’s Master’s research at the University of Waterloo focused on airflow in high-rise multi-unit residential buildings and included extensive testing and monitoring of a case study building. As a result, his work has developed the industry’s understanding of airflow in and around buildings and how it affects both energy consumption and indoor air quality.

Lorne’s practical experience combined with his theoretical training and proficiency with state-of-the-art thermal and hygrothermal (heat, air, and moisture) software modeling tools has enabled him to evaluate a wide variety of enclosure systems. This analytical work is used as the basis for recommendations regarding air barriers, vapor barriers, insulation levels, thermal bridging, and window selection.

DoCoMoMo_Oregon and the Association for Preservation Technology, Northwest, are pleased to co-host a work- shop on Mid-Century Modern materials. The workshop will focus on materials used in the northwest through their history and case studies. The sessions will conclude with a lively discussion as to whether preserving Mid-Century Materials is less important than preserving the plan and layout of Mid-Century structures. A sack lunch will be provided to all attendees.

AFTERNOON SESSION / PANEL DISCUSSION

• Veteran Memorial Coliseum: The Challenges of Mid-Cen- tury Modern Spectator and Events Venue. Presented by Susan Hartnett, Spectator Facilities and Development Manager, Portland Office of Management and Finance.
• Case Studies: Interventions and Additions to Modern Seattle Landmarks. Presented by Susan Boyle, Principal, BOLA Architects.
• Panel Discussion: How important is it to retain original materials vs. plan concepts? Moderated by Brian Rich, Principal, Richaven Sustainable Preservation.

This seminar will discuss the impact of the NFPA 285 Test on buildings using IBC and ASHRAE 90.1 energy code requirements, the parameters and history of NFPA 285, and the definition of what building envelope components are combustible and require NFPA 285 testing by IBC. All of these elements combine to integrate NFPA 285 compliant assemblies into building envelope systems.
