Regular Monthly Meeting

December 2016 Monthly Meeting

Time: 
Dec 6 2016 - 12:00pm - 1:30pm
Meeting Title: 

Cladding Attachment

Location: 

Aceh Community Room
Mercy Corps, 45 SW Ankeny St
Portland, OR 97204

Presenters: 

Ariel Levy, PE

Description: 

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. This presentation will review some of the more commonly observed cladding attachment systems in the marketplace, review some of the nuances of each, help us to understand the associated structural and thermal expectations, and finally present a method of assessing the combined structural and thermal capabilities from a design-tool perspective.

Ariel’s experience spans geographically across North America and includes buildings of all types: new to old, residential to high-rise. He has broad experience with a wide range of building enclosure systems, and his clients span the range including architects, owners, developers, contractors, property managers, lawyers, and insurers. Ariel is a Portland native and has practiced in Oregon for over a decade. Prior to his return home, Ariel spent several years practicing in Boston and Los Angeles. Ariel is also a Managing Principal of RDH, and oversees all aspects of operation in its Oregon and Northern California offices.

November 2016 Monthly Meeting

Time: 
Nov 1 2016 - 12:00pm - 1:30pm
Meeting Title: 

Specifying and Conducting Building Air Leakage Tests

Location: 

Aceh Community Room
Mercy Corps, 45 SW Ankeny St
Portland, OR 97204

Presenters: 

Terry Brennan

Description: 

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. In construction, the design and construction teams require an understanding of what needs to be included in the tests to avoid pitfalls, how to set up buildings for qualitative and quantitative testing, and how to interpret the results if the team is testing to a standard, pre/post retrofit comparisons, or comparing the results to other buildings.

Terry is a building scientist and educator. He is on the editorial boards of Environmental Building News and Heating Piping and Air Conditioning Magazine. He currently chairs the U.S.A.C.E committee developing new air leakage protocols. Past work includes consulting on a research project to restore three homes in the Seventh Ward of New Orleans after Hurricanes Katrina and Rita, teaching healthy housing courses for the National Center for Healthy Housing and working on a research project to study unplanned airflows in commercial buildings in New York State. He is a member of ASHRAE 62.2 Ventilation and Air Quality Committee and served as consultant to the National Academy of Sciences Committee on Dampness and Health in Buildings. He holds a Bachelors degree in Physics and a Masters degree in Environmental Studies.

October 2016 Monthly Meeting

Time: 
Oct 4 2016 - 12:00pm - 1:30pm
Meeting Title: 

A Comparison of Liquid Applied WRB Chemistry, Performance, Capabilities and Applications

Location: 

Aceh Community Room
Mercy Corps, 45 SW Ankeny St
Portland, OR 97204

Presenters: 

David Kimball

Description: 

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.

September 2016 Monthly Meeting

Time: 
Sep 13 2016 - 12:00pm - 1:30pm
Meeting Title: 

Evolution and Understanding of Attic Ventilation

Location: 

Aceh Community Room
Mercy Corps, 45 SW Ankeny St
Portland, OR 97204

Presenters: 

Lorne Ricketts

Description: 

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.

June 2016 Monthly Meeting

Time: 
Jun 14 2016 - 4:00pm - 5:00pm
Meeting Title: 

Building Tour: Overton Apartments

Location: 

NW 12th and NW Overton Portland, OR
