As we move toward higher performance buildings supported by advanced technologies, we require more advanced tools to not only analyze but also disseminate the information. This session will use data driven guidance and highly visual tools to communicate a more complete picture of whole building energy performance. The frameworks presented will highlight the relationships between multiple performance variables, allowing designers to make more informed decisions and building energy policy makers to focus attention on areas of higher priority. The session will include a brief overview of the recently published Building Envelope Thermal Bridging Guide (available publicly, free of charge), followed by a “how-to” use the guide, using building case studies and hands-on examples. The exercise is meant to teach participants how to use the guide, but also to understand the implications that the information has on opaque building envelope performance.

The second part of the session will introduce the concept of building energy performance mapping (BEPM) using unique visualization techniques. With a case study as a backdrop, we will explore how the use of BEPM can put into context building performance characteristics, such as thermal bridging and wall R-values in comparison to glazing, architectural massing and other parameters. Highly visual tools will be used to consolidate vast amounts of data into a package, allowing architects and designers to make informed decisions throughout design without relying solely on, or waiting for, project-specific calculations. The ease at which BEPM helps visualize results makes it accessible to all designers, allowing this part of the presentation to be highly interactive.

Glen is currently working on the PDX Next Main Terminal Expansion project as the lead for the vertical envelope and his recent projects include the Nike World Headquarters Expansion, Sebastian Coe Building, the GSA Federal Center South Building Complex and the Twelve | West Mixed-Use Building.

This course will cover Electronic Leak Detection (ELD) testing methods used for quality assurance of roofing and waterproofing membranes. Participants will learn about the principles outlined in the ASTM Standard Guide D7877 and ASTM Standard Practice D8231 and will be able to identify which assemblies are compatible with electronic testing and active monitoring.

Shaun Katz has been with Detec Systems for 7 years and has over 20 years of experience in customer service, sales and business administration. Shaun has assisted contractors, architects, engineers and consultants, manufacturers, facility managers and building owners with forensic leak investigation, as well as leak detection testing in new construction. He has performed presentations and demonstrated ELD throughout the world, and won the 2020 Presenter of the Year Award from the Chicago chapter of IIBEC.

His goal is to provide a basic understanding of Electronic Leak Detection and to assist design teams with ensuring valid and conclusive ELD.

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.
