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.

As the vegetated roofing industry continues to grow and mature, the Ecoroof Symposium will showcase the most up-to- date research on the economic and environmental impacts that green roofs provide to buildings and cities. We are honored to host London’s own Dusty Gedge as our keynote speaker, as well as a research medley on topics such as enhanced real estate value, energy impacts, and biodiversity. Panels of experts and breakout sessions offer a wealth of experience on best practices to avoid concerns, and to extend the service life of the roof membrane and vegetation. Green roof tours can provide insight into a variety of systems and approaches.

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.

The Portland Building Enclosure group will be organizing a tour of the in-progress Overton apartment building in the Pearl District.

Currently, Unico is constructing NV (www.nvportland.com), a 26-story, 275-unit, Class-A+ apartment development in Portland, Oregon’s Pearl District. Located at NW 12th and NW Overton, NV residents can anticipate 360 degree views of the Portland cityscape, Pearl District, Fremont Bridge, eastern mountains, and West Hills.

The project is located between NW Pettygrove/NW Overton and NW 13th Ave/NW 12th Ave. Touring guests will need to check in, sign in and fill out the waivers - please congregate near the corner of NW Overton and NW 13th Avenue at 4pm on Tuesday, June 14th.

Please RSVP to John Duncan for headcount purposes.

ZGF and Andersen are working on the new Overton Apartment building being built in the Pearl District. Andersen asks that guests bring their own PPE, including: 1. Hard hats 2. Vests 3. Pants 4. Shoes w/ankle support 5. Safety glassesThe following systems can be observed at the tour:

The window wall is mostly finished, but can be observed from interior & exterior. Storefront is in progress. Curtain wall may be in progress as well. Brick is in progress at the podium, and metal panel is in progress at the tower. Some in-progress foundation waterproofing assemblies will also be visible.

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.

Herman Lopez is a Commercial Business Development Manager with DuPont Building Innovations. He is based in Fort Collins, CO and responsible for commercial business development throughout Western US representing DuPont Weatherization Systems. He has over 20 years sales and business development experience in the commercial and residential construction markets having worked for Simpson Strong-Tie, Azek Trimboards and DuPont™ Building Innovations. He is also active with CSI, (Construction Specifications Institute) and BEC (Building Enclosure Council). He speaks at many AIA-BEC Chapter meetings throughout the US as a representative of DuPont.

Effective building enclosures provide physical protection from weather and climate (comfort), indoor air quality (health), durability, and energy efficiency. This presentation will focus on the fundamentals of wall assembly design with emphasis on the control layers that separate exterior and interior environment.

As part of the discussion, we will examine the physical phenomena that affect buildings and strategies that can be employed through Control Layers to respond to the environment.

Stevan serves as the Sustainability Practice Lead for Morrison Hershfield's Pacific Northwest offices and has provided green building consulting, building envelope/durability and commissioning duties on sustainability projects in Canada and in the US. Further to sustainability, Stevan has over 16 years of building science experience completing several building envelope assessments for building envelope failures as well as design assist services to architects on new construction projects. His experience also includes 3rd party building envelope drawing review, specification writing and construction drawing preparation of envelope systems. His experience in building envelope contributes to a better understanding of whole-building systems in his work in green buildings

With the ever-evolving technology of materials and construction trade practices combined with the desire to push project schedules to year-round construction, the risk of failure of building enclosure components is high. During this course, the discussion will revolve around case-studies of real-world building enclosure system failures resulting from discontinuities in the control layers (air, water, vapor, thermal), lack of understanding of the interaction between the interior and exterior environments, and construction related mistakes. Conditions include roof-to-wall transitions, SIPS panel detailing, precast concrete panels, lightweight concrete construction and other conditions.

Below grade waterproofing is becoming increasingly important as occupants, owners and warranty providers are less tolerant to water ingress into below grade structures and local jurisdictions are increasingly limiting rain and storm water discharge. There are various water management methodologies and waterproofing systems available to provide protection against water ingress of foundations. This presentation provides insight into various waterproofing strategies and systems for below grade foundations. Factors that contribute to the performance of a dry below grade foundation will discussed including soil retention, ground and surface water flow rates, hydrostatic pressure, dewatering and drainage, foundation forming, concrete mix design, steel reinforcement, waterproofing membrane and accessories, weather during installation, contractor experience, design, details, field review and cost.
