Course Description
• After a prolonged emphasis on concrete and steel for non-residential buildings, design professionals are using wood to great effect in a growing number of commercial and multi-family building types. Innovative applications for wood today include retail, schools, healthcare facilities, churches, bridges, industrial facilities, offices, student housing and more. Some applications are driven by wood's aesthetic and warmth while others cite its versatility or low carbon footprint. Their collective path has been made possible by building codes that increasingly recognize wood's structural and performance capabilities, and the continued evolution in the science and engineering of wood building systems and techniques.
• This session will challenge preconceptions about wood construction, while offering innovative solutions to current problems and providing attendees with a comprehensive background to move forward with taller, larger and more innovative wood structures.
Course Description Continued 1. Why any material? Wood has been a sought-after material for centuries thanks to its
renewability, affordability, warmth and beauty. More recently, its carbon benefits in comparison to concrete and steel have placed it at the forefront of green building design. The speaker will discuss life cycle comparisons of wood versus other structural materials and how the use of wood reduces a building’s carbon footprint. Sustainable forestry will be examined, including a discussion of myths and facts. The session also will explore how wood performs in the areas of durability, fire and moisture.
2. Building codes: Learn how the International Building Code increased the possibilities for wood construction by recognizing additional fire protection techniques, consolidating the maximum allowable areas and heights from the three legacy codes into one and allowing the use of wood in a wider range of building types. The session will look even further to building projects that have pushed the boundaries of wood design and construction.
3. Innovation: From six-story mid-rise to 30-story wood composite structures to wood bridges with 100-year service lives, the world of wood today is an exciting display of creativity and invention. Innovative wood materials and building systems are reducing the carbon footprint of the built environment while allowing wood to reach new heights, create safe havens in seismic zones and maximize energy efficiency. The session will showcase diverse projects from around the world to demonstrate innovation and inspire collaboration of materials destined to influence building professionals for decades to come.
Learning Objectives
• At the end of this program, participants will be able to:
1. Recognize the benefits of wood materials through evaluation of all materials using Life Cycle Assessment methodology.
• 2. Challenge preconceptions and myths related to forestry and the use of wood materials use in terms of sustainability, moisture, durability, and fire, through historical and contemporary project examples.
• 3. Make use of provisions in the International Building Code that allow designers to increase the allowable heights and areas of building projects beyond the stated tabular limits.
• 4. Utilize innovative wood materials and hybrid wood, steel, and concrete building systems that are being developed around the world today through exposure to a variety of project case study examples.

Biophilia
What is the difference between a ‘philia’ and a ‘phobia’?
“The connections that human beings subconsciously seek with
the rest of life”
Biophilia = “love of living systems”
Is there an emotional connection…
