WBDG Whole Building Design Guide

Building Envelope Design Guide (BEDG)
Under guidance from the Federal Envelope Advisory Committee, the National Institute of Building Sciences has developed this comprehensive guide for exterior envelope design and construction for institutional/office buildings. The BEDG is continually being improved and updated through the Building Enclosure Councils (BECs).

Architecture and Building Science Education in North America, Challenges and Opportunities

A recent workshop on Building Science Education in North America hosted by ASTM International and the National Institute of Building Sciences, spurred frank discussion about the place of the modern architect in building design and construction. The workshop was held during ASTM’s May committee week in Toronto, Ontario, Canada, and attracted more than 100 participants ranging from students to professors to department chairs representing U.S. and Canadian colleges and universities as well as practicing design and construction professionals and representatives from both the legal and insurance communities north and south of the border.

Speakers included:

  • Dr. John Straube, University of Waterloo
  • John Fernandez, Director of Building Technology, Massachusetts Institute of Technology
  • Dr. Georg Reichard, Virginia Tech
  • Ronald Krpan, PE, British Columbia Institute of Technology
  • Henry Green, Hon. AIA, President, National Institute of Building Sciences
  • Patrick Huelman, University of Minnesota
  • Samuel Rashkin, U.S. Department of Energy
  • Hua Ge, Concordia University
  •  Andrew Dunlap, SmithGroup Architects
