During this presentation, Roy Denoon, will explain how there are several ways of obtaining design information for wind effects on building envelopes. This presentation will discuss the application of codified approaches and some of the relevant changes in ASCE 7-22. The alternative of wind tunnel testing to determine design wind pressures will also be illustrated with examples of when it can be an advantageous option in terms of reducing construction cost and/or ensuring reliability goals are met. Roy will also give an overview of the application of performance-based wind design approaches to building envelope design. Methods of determining wind loads on building appurtenances such as vertical fins or horizontal shades will be described, and examples of misbehaving building envelopes elements will be shown. 

 Roy Denoon is a Senior Principal and Vice President of CPP Wind Engineering & Air Quality Consultants, based in Colorado. Over his 30-year career in wind engineering, Roy has worked on projects all over the world including two Olympic Stadiums and the world's tallest building. He is a co-author of the CTBUH Guide to Wind Tunnel Testing of Tall Buildings, the ASCE/SEI Prestandard for Performance-Based Wind Design, and the ASCE/SEI Manual of Practice 143 on Design and Performance of Tall Buildings for Wind. He is a member of the ASCE 7 Wind Loading Subcommittee.  

This presentation is pending for 1 hour of AIA continuing education credits.
