If you have an interest in the design and construction of building enclosures, the BEC is an organization to join. The goal of the BEC is to promote the pursuit of excellence in the design, construction, and performance of the building enclosure. Membership represents an interdisciplinary forum of architects, engineers, consultants, manufacturers, contractors, developers, etc. BEC-Chicago meets once a month. At these meetings, which are typically an hour long, members share information on ongoing projects, issues, and research; sources of reliable information on design and construction practices; and lessons learned. Many of our programs offer accredited continuing education units.
