This April 13-15 in Kansas City NIBS is hosting the fourth conference on building enclosure science and best practices known as BEST 4 (Conference Building Enclosure Science & Technology). These are amazing events addressing the issues central to the architect’s mission of designing and delivering better buildings that last longer and perform far better than buildings ever have. BEST is coordinated with the DOE Whole Buildings Conference and the National Building Envelope Council of Canada’s Canadian Conference on Building Science and Technology. Especially useful is that many of the papers presented at previous BEST conferences (1, 2, and 3) are posted on the BEST site: http://www.nibs.org/?page=best
