John Reynolds will be joining us from the University of Oregon to discuss passive cooling and heating. Oregon's climate offers architects the opportunities of both passive solar heating and passive cooling. Passive and energy-conserving buildings seek to manage the available thermal energy by lowering peaks and filling valleys in order to maintain comfortable conditions for the occupants. Thermal mass and glass are two of the more powerful tools designers can use to control these conditions. John will discuss the principles of passive cooling and heating, the materials involved and their optimal locations within the wall assemblies.

This month’s BEC meeting will feature a construction site tour of the Mercy Corps Headquarters in downtown Portland. The tour will focus on the design and construction issues associated with the building enclosure systems for this project that is pursuing LEED Platinum certification.

Tour leaders will include Bhavna Kumar and Mike Steffen of Walsh Construction Co./OR and Charles Dorn of THA Architecture. The meeting will commence in Room 152 of the White Stag Building at 3:30pm, where a brief overview of the project design and detailing will be provided. Participants will then adjourn to the building site for a one hour tour. The building site is one block south of the White Stag Building. Please note: participants should wear long pants and closed-toe shoes (work boots preferably). Hard hats will not be required for this tour.

As the trend toward re-using buildings grows, re-skinning buildings will become ever more prevalent.  Presenters from SERA, Howard S. Wright, and Benson will give a very brief presentation and then a tour of the building emphasizing the story of the envelope.  The tour and presentation will tell the story of the project and the envelope.  Please bring a hard had and construction appropriate footwear.

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.

The tragic fire in London, UK, raises issues with respect to claddings and continuous insulation in high performance buildings as well as retrofits. The first part of this session addresses the physics of the fire in London and why such an occurrence is unlikely in the United States and Canada.

Billions of dollars worth of hard coat stucco litigation have been filed within the last 12 months. What is driving the stucco failures? The patterns are eerily reminiscent of the failures of EIFS claddings in the 1990’s. The second part of this session addresses the changes in materials and construction practice leading to the failures.

The Portland Building Enclosure group will be organizing a tour of the in-progress renovation of the Portland Building. The project is located at 1120 SW 5th Ave, Portland, OR 97204. Touring guests will need to check-in, sign-in, and fill out waivers prior to the tour; please congregate under Portlandia at fifteen minutes prior to the tour Thursday, April 4th.

DLR Group and Howard S Wright are working on the new renovation of this iconic building. We ask that guests bring their own PPE, including: 1. Hard hats 2. Vests 3. Pants 4. Shoes w/ankle support 5. Safety glasses.

Designed by Michael Graves and built in 1982 as administrative offices for the City of Portland, The Portland Building is an award-winning example of Post Modern architecture. The building was later placed on the National Register of Historic Places as a building of “exceptional importance,” but it currently faces problems with its structure, exterior, and operational systems that repairs alone cannot address. To protect and preserve this major public investment, the City has initiated a $195 million project to reconstruct the Portland Building by the end of 2020. The City will create an adaptable building that will last 50-100 years, providing a productive work environment for employees and a welcoming space for community members.

The Portland Building Reconstruction project brings the City an opportunity to create a building that meets current and future needs. The completed building will provide a welcoming environment for our community and ensure viable office space to serve the public well into the future.

The Project includes:


• Repair/replacement of the building exterior
• Repair/replacement of electric, mechanical, plumbing, and technical systems
• Seismic upgrades

• Improved accessibility for all occupants and visitors

• Workspace and safety improvements

• LEED Gold building certification
• Historic preservation

The tour will be limited to 30 participants in two groups. The first group from Noon to 1 and the second group from 1 to 2.

Oh no! What did I miss? How to properly specify an air barrier system Laverne Dalgleish

Design and Construction documents are one of the first steps towards achieving an effective layer of airtightness to manage moisture and air movement. The importance of a proper specification cannot be understated and a well-articulated document will ensure that the owner is provided with materials, performance and quality. The presentation will review some of the consideration and language that should be reviewed prior to developing a specification and will outline code requirements, performance requirements, what can be done for quality and ensuring material selection meets the intent of design and for crucial coordination with other components of the enclosure.

“By Others” The Elusive Subcontractor Responsible for Transitions Andrew Dunlap

This course will take you through a multitude of details with a review of assembly environmental separators that will show common enclosure assembly discontinuities and provide an education on common system transition methods.

Air Barrier Material Evaluations & Testing: Why Peanut Butter Is Good For A Sandwhich But Not For Your Air Barrier Laverne Dalgleish

Air barrier technology has been around for decades, but the use of air and water resistive barrier material in buildings is fairly new. Some air and water resistive barrier materials have been used in other applications for years and now are being used for the air and water control layer. Now that the application has changed, does the material still perform in the new application? As the air and water resistive barrier industry has grown over the past decade, new materials have come on the market. These materials have a short track record, but should you shy away from using them? This presentation shows how you can sort out the different materials and how you can get help in choosing the right one for your project.
