3 Course Description The use of wood-frame construction for mid-rise projects is innovative in its ability to achieve multiple, simultaneous objectives. Wood is a code-compliant solution to the issue of how to cost-effectively increase density while creating vibrant urban environments. A renewable resource, it can also help meet the sustainability requirements of even the most stringent green building rating systems, while offering the additional benefit of carbon sequestration. The innovative use of wood is in fact changing the skyline. Increasingly, five- and six-story wood buildings are rising up among traditional concrete and steel shells as designers and developers embrace timber s vast potential for lower costs, faster installation, and a significantly lighter carbon footprint. Through the use of case studies, this session will showcase recently completed projects that illustrate this trend. Topics will include current code allowances for mid-rise wood buildings, design strategies and environmental performance. Discussion will also touch on the international trend toward even taller wood buildings, made possible by emerging research and the development of advanced wood products and technologies.

4 Learning Objectives 1. Evaluate the opportunities for wood frame structures in mid-rise projects. 2. Interpret local code language on the allowance of wood framing above three stories. 3. Envision the opportunities for mass timber structures of 10 stories or more. 4. Communicate the benefits and dispel the myths of mass timber framing.

20 Spartan Village, UNC Greensboro, NC We assumed that wood framing would be a little less expensive, but actually found it gave us significant cost advantages. We saved $15 per square foot which, for a 385,000-square-foot project, is a lot of savings Raymond Hunt EDC Development Management Lord, Aeck & Sargent Architecture TFF Architects & Planners
