This presentation by Christian Ozbun of Weathertight Consulting provides a technical guide for specifying and performing building enclosure testing to ensure field performance matches manufacturer data. It details critical ASTM and AAMA standards for evaluating air leakage (ASTM E783/E1186), water penetration (ASTM E1105/AAMA 501.2), and material adhesion (ASTM D4541/C1521) across windows, curtainwalls, roofing, and air barriers. Review the use of reduced field test pressures (typically 2/3 of lab values), the importance of early mockup testing, and the implementation of a Building Enclosure Commissioning (BECx) matrix to verify project-specific performance criteria.
Learning objectives
- Overview of various test methods.
- Which test methods should be specified for a given system.
- Understand general guidelines for location and quantity of testing.
- Guidance for specifying building envelope testing.
- Understand how manufacturer performance data translates into field test pressures.
- Learn when diagnostic testing should be performed.
