The Portland BEC (Building Enclosure Council) was formed in December 2005 as a committee of the Portland Chapter of the AIA. It is a part of a national network of BECs established by an agreement in May 2004 between the AIA and BETEC, the Building Enclosure Technology and Environmental Council of the National Institute of Building Sciences (NIBS).
In 2011 the Portland BEC became an IRS 501(c)(3) non-profit charitable organization supported by its individual, corporate, and student members. The Portland BEC is run by [an elected group of officers](http://www.portlandbec.org/officers/) and a board of directors.
The purpose of the organization is to promote and encourage discussion, training, education, technology transfer, the exchange of information about local issues and cases, relevant weather conditions and all matters concerning building enclosures and the related science.
The organization is charged with providing a forum for the construction industry in the crucial area of building enclosures.
The Portland BEC meets at noon on the first Tuesday of scheduled months at the Mercy Corps Building. The meeting lasts 1 1/2 hours and is structured around a presentation on issues relevant to the building enclosure. Anyone with an interest in improving the quality of the built building enclosure is welcome to attend.
