Compliance, Comfort, Durability: Fundamentals of Wood Building Design

July 17, 2014 – 8:15 am - 1:00 pm


Seattle, WASeattle, WA


On-site check-in: 7:30 am
Workshop begins: 8:15 am
Workshop concludes: 1:00 pm

Preservative-Treated Wood: Use and Specification

Butch Bernhardt, Western Wood Preservers Institute

In applications where wood may be exposed to moisture, insects or fungal organisms, preservative-treated wood can help ensure a building’s durability. In this presentation, participants will learn about the manufacturing process for pressure-treated wood, available products and their differences, and how preserved wood is used in construction. Topics will include types of preservative treatments and the required levels of retention, as dictated by the end-use application, desired service life and exposure conditions. AWPA Use Category standards and ICC-ES Report Evaluations will be reviewed, and current issues concerning treated wood in residential and commercial construction will be discussed. Participants will also receive free access to the Treated Lumber smartphone app.

Butch Bernhardt is the program and communications manager for the Western Wood Preservers Institute (WWPI) based in Vancouver, Wash. Bernhardt has provided product support and education on wood products for nearly three decades. His responsibilities at WWPI include product education, technical publications, standards, distance learning and digital design tools for preserved wood products. Bernhardt holds a Bachelor’s degree from Oregon State University and is the third generation in his family to work in the wood products industry.

Energy Code Compliance: Wood-Frame Buildings and the IECC
Andrew Klein, PE

This presentation focuses on the challenges of meeting 2012 International Energy Conservation Code (IECC) requirements in modern wood-frame buildings, as well as related design considerations. Topics will include the code’s scope, content and significant changes since the 2009 edition. Compliance path options will also be discussed in the context of specific building systems and features.

Andrew Klein is a consulting engineer who specializes in building and energy code compliance. He is involved in national-level committee work and building code development with the International Code Council (ICC), National Fire Protection Association (NFPA) and International Association of Plumbing and Mechanical Officials (IAPMO). He is a licensed Professional Engineer in the state of Washington and a Certified Energy Manager (CEM) through the Association of Energy Engineers (AEE).

Urban Acoustics
Steve Thorburn, PE, LEED AP, CTS-I, CTS-D, Principal Consultant, Thorburn Associates

As with any issue of building performance, the acoustics of a mixed-use wood-frame structure can be designed to meet or far exceed minimal requirements. It is the responsibility of the design team to determine acoustical expectations for the project and meet them within the available budget. Through the use of case studies, this fast-paced, interactive session will explore how multi-story wood systems can be used to meet acoustical privacy goals. Discussion will focus on the detailing and construction of units, and how consideration of the construction process can help keep acoustical costs down. With the objective of providing implementable solutions, the session will include construction details and photos showing what has and hasn’t worked in actual buildings.

Principal Consultant with Thorburn Associates, Steve enjoys helping others understand the principals of acoustics and audiovisual technology. His dual degrees in electrical engineering and technical theatre give him a

balanced left brain/right brain approach to project solutions. In addition to experience on more than 2,800 projects, he is an author and teacher, a past INFOCOMM Educator of the Year, and recipient of two International Communications Industries Association Facility Design Awards. He routinely speaks and writes for the AEC industry on acoustical issues.
