This presentation is a technical discussion about using field measurements to validate thermal assumptions for existing buildings and help make energy models more accurate. In deep energy retrofits, the thermal performance of existing building envelopes is often difficult to determine with a high level of accuracy. For older buildings, the records of existing assemblies are often incomplete or inaccurate. To obtain greater baseline performance accuracy for energy models, in-field measurement tools can be used to obtain data on the thermal performance of the existing assemblies.

This course will provide a brief history of significant historical fires and how these have influenced the development of our current model building codes. Some more recent fires will be discussed, reinforcing the importance of mitigating fire propagation in cladding assemblies. A review of the five main building types will lead into a discussion of material combustibility followed by an overview of the Code requirements around flame propagation.

Installing a solar roof system on a building should be a decision that rewards the building owner with energy savings as well as piece of mind knowing they are doing their part to help the environment. What many building owners may not realize is that installing a solar roof system could damage their roof, void their roof warranty and end up costing them more in the long run. “Solar Roof Systems- The Good, The Bad and The Ugly” will identify the potential issues with a rooftop solar installation, what questions they should be asking and how to avoid serious, costly problems.

Please note that this meeting will occur on a Thursday

Architectural Aluminum Framing Systems can be broken down into a number of subcategories. These are: Storefront, Curtain Wall, Window Wall, Overhead or Sloped Glazing, Windows, Entrances, Interior Frames and Sliding Storefronts. The first three categories: Storefront, Curtain Wall and Window Wall are most commonly used for fixed exterior glazing on commercial applications. Each shares some common characteristics but for the most part, each is very different and designed for specific applications.

For our October 1, 2024 Portland BEC meeting, we have arranged for a unique opportunity to tour the ongoing construction of the OHSU Hospital Expansion Project (OHEP). This 14-story, $540M immediate care facility features approximately 500,000 sf of programmed space and parking, planned accommodations for up to 192 beds, 250,000 sf of unitized curtain wall, 10,000 sf of vegetated roof, and three (3) bridge connections to adjacent campus buildings.

Building science is a dynamic field that integrates age-old practices with cutting-edge research, offering critical insights into the design and construction of buildings. While some principles have been established for centuries, our understanding of building science continues to evolve as new research and industry experiences emerge. In recent years, there has been a growing recognition of its value, especially in addressing the complexities of modern construction and mitigating risks.

General Information

The Portland Building Enclosure Council is pleased to announce the 2024 Symposium. This year’s Symposium will focus on building enclosures responding to a changing climate.

The symposium is a full day event, comprised of presentations, speakers, and opportunities for sidebar conversations.

Mass timber is both an innovative building material and a fundamentally familiar material. This course will cover some of the challenges which can be encountered when using this material with an emphasis on the construction process. This course will address the nature of wood material and how it reacts to moisture and relate that to the practical use of mass timber as a construction material. The standards applying to mass timber moisture content during both manufacturing and fabrication and then erection and construction in general will be reviewed.
