With the ever-evolving technology of materials and construction trade practices combined with the desire to push project schedules to year-round construction, the risk of failure of building enclosure components is high. During this course, the discussion will revolve around case-studies of real-world building enclosure system failures resulting from discontinuities in the control layers (air, water, vapor, thermal), lack of understanding of the interaction between the interior and exterior environments, and construction related mistakes.

Effective building enclosures provide physical protection from weather and climate (comfort), indoor air quality (health), durability, and energy efficiency. This presentation will focus on the fundamentals of wall assembly design with emphasis on the control layers that separate exterior and interior environment.

As part of the discussion, we will examine the physical phenomena that affect buildings and strategies that can be employed through Control Layers to respond to the environment.

This seminar will discuss the impact of the NFPA 285 Test on buildings using IBC and ASHRAE 90.1 energy code requirements, the parameters and history of NFPA 285, and the definition of what building envelope components are combustible and require NFPA 285 testing by IBC. All of these elements combine to integrate NFPA 285 compliant assemblies into building envelope systems.

The Portland Building Enclosure Council will be holding our bi-annual symposium on May 11, 2016 at the Portland Art Museum. The event will be held in conjunction with CSI-Portland’s Industry Forum (IF) event taking place on the same day. This combined event promises to provide a full day of educational and networking opportunities related to practice and theory in architecture and technical aspects of building enclosures in energy retrofit applications. The proposed schedule of events and speakers are is as follows:

DoCoMoMo_Oregon and the Association for Preservation Technology, Northwest, are pleased to co-host a work- shop on Mid-Century Modern materials. The workshop will focus on materials used in the northwest through their history and case studies. The sessions will conclude with a lively discussion as to whether preserving Mid-Century Materials is less important than preserving the plan and layout of Mid-Century structures. A sack lunch will be provided to all attendees.

MORNING SESSION

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.

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.

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.

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.

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.
