Avoiding Building Enclosure System Failures

Track 3: Testing & Inspection

Wednesday, March 27, 1:00 – 2:00pm

The presentation will review the four barriers needed for effective building enclosure systems. Proper location of the four barriers based on climate region and building use will be reviewed. Examples of failed building enclosure assemblies will be reviewed along with the reasons why they failed. Building enclosure designs that would fail will be reviewed. The reason why they would fail and the design changes that actually prevented them from failing will be reviewed.

Learning Objectives:

  1. Learn the Four Barriers needed for effective building enclosure systems
  2. Learn where to properly locate these four barriers for effective building enclosure
  3. Learn about failures to do improper design and location of the four barriers
  4. Learn how building enclosure systems are analyzed to insure effective performance
