May 2017 Monthly Meeting

In the roofing industry there is a difference between wind speeds and wind pressure on the roofing system. This presentation takes a look at these differences and suggests ways in which specifications can be written, and roof systems designed, to meet the local code requirements.

April 2017 Monthly Meeting

Continuous exterior insulation, when used correctly, can resolve multiple building performance challenges. In this presentation, we will look at two topics: condensation and effective R-values. Condensation can lead to mold or rot on building enclosure surfaces, as well as within the enclosure’s inner layers. You will learn how to assess and minimize condensation risk in various assemblies, including how to reduce risk using continuous exterior insulation.

March 2017 Monthly Meeting

In a world where energy-efficiency and sustainable solutions are increasingly prioritized in building projects, it is important for architects, contractors and all building professionals to make informed decisions when selecting components of the building envelope. In an effort to assist building owners and design professionals in the selection of fenestration products, the National Fenestration Rating Council (NFRC) has designed a rating system in which all products are evaluated under equal terms, enabling a fair comparison of products from different manufacturers.

February 2017 Monthly Meeting

Grant Park High School in Portland, Oregon is a multi building campus featuring buildings and additions built over a period of time from 1923-1966. Composed largely of concrete frame structure with brick infill, the cladding has exhibited an accelerated degree of masonry spalling at a number of the buildings on various different elevations.

January 2017 Monthly Meeting

Subgrade waterproofing presents unique challenges in that corrections can be difficult post installation. This panel discussion will examine common problems and what steps can be taken to avoid them. The panel will examine remediation techniques and strategies for mitigating problems in existing buildings and remodels.

The panel will include perspectives from Designers, Installers, and Manufacturer Representatives, as we review questions and project examples.

December 2016 Monthly Meeting

Drained- and Rain-Screen cladding design has become commonplace over the last number of years, at least in many of our Northern-US practice areas. As a result, the industry has shifted much of its research and design effort to the further advancement of both the structural attachment methods for cladding and the improvement of the thermal properties of the attachment. The market today is filled with a variety of clip systems, thermally efficient girts, and other solutions for achieving both structural and thermal load resistance requirements.

November 2016 Monthly Meeting

Air tightness testing is becoming more prominent in building codes across the country with an ever increasing focus on energy conservation and indoor air quality control. This presentation focuses on how to select and perform building airtightness tests. During design, properly specifying an air tightness test requires the design team to be able to identify the air, thermal and vapor control layers throughout the building to determine the building enclosure and understand the various air tightness tests available.

October 2016 Monthly Meeting

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.

2016 Ecoroof Symposium

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.

September 2016 Monthly Meeting

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.
