The Cold-Formed Steel Engineers Institute (CFSEI) will host a webinar on “Introducing AISI S250, North American Standard for Thermal Transmittance of Building Envelopes With Cold-Formed Steel Framing,” on Thursday, December 16, 2021 from 3:00 p.m. to 4:30 p.m. EST. The webinar will be conducted by Jonathan Humble, FAIA, NCARB, LEED BD+C, regional director of construction codes and standards for the American Iron and Steel Institute (AISI). It is designed for architects, engineers, building officials and contractors. Participants are eligible for 1.5 PDHs. 

The webinar will walk attendees through the history, development and contents of the new AISI S250 standard. Participants will obtain a relative understanding of how to apply the various provisions of the standard in order to evaluate the thermal capabilities of envelope assemblies (e.g., walls, ceilings/roofs) containing cold-formed steel framing for use in professional practice. Jonathan Humble led the work group responsible for the development and publication of the AISI S250 standard. 

As regional director of construction codes and standards for AISI, Jonathan Humble is involved in research and development of new technologies for AISI standards and guides, participates in national model codes and standards development, and provides educational services to steel industry members, design professionals, code officials, general contractors and building owners. He holds Bachelor’s and Master’s degrees in Architecture from the University of Wisconsin-Milwaukee. He is licensed as an architect in Connecticut and Massachusetts, is NCARB-certified, and holds a LEED AP-BD+C credential. He received architectural awards for his designs while in the practice of architecture. 

Jonathan was inducted into the American Institute of Architects (AIA) College of Fellows for his outstanding contributions to the AIA and its membership. He is a recipient of the International Code Council’s Honorary Membership, ASHRAE International’s Distinguished Service Award, National Fire Protection Association’s Committee Service Award, and the Cool Roof Ratings Council’s Marty Hastings Award, all in recognition of his exceptional service and contributions to these codes and standards organizations.
