NEBB Building Enclosure Testing (BET) Building enclosure technicians performing BET-level testing spend their days measuring air leakage rates, thermal bridging, and moisture infiltration across commercial facades, rooflines, and window assemblies. You’ll operate blower doors, infrared cameras, and manometers to diagnose why energy bills climb or occupant complaints spike. This credential positions you to lead diagnostic investigations that directly shape retrofit priorities and construction remediation budgets.
