CHICAGO — The National Environmental Balancing Bureau (NEBB) recently released its Procedural Standards for Building Envelope Testing standards.
The release is NEBB’s newest discipline and addresses the ability to test and quantitatively report the performance of the airtightness of today’s building enclosures. Two procedures are provided for the practitioner to follow in testing the integrity of the enclosure, a blower-door test method and a building HVAC system test method.
