Building Enclosure Testing Seminar – June 2025

The seminar and exam will be held at NEBB TEC in Gaithersburg, MD

Building Enclosure Testing (BET) is an important and growing field in our industry. It addresses a distinct need within the building and construction industry – the ability to test and quantitatively and qualitatively report the performance of the airtightness of today’s building enclosures.

BET is a process involving evaluation, verification, and documentation that a building’s design and construction meet defined performance expectations.  In addition to fewer water leakage/mold issues for both new construction and renovation projects, BET results in better building energy performance through improved thermal performance and decreased air leakage issues.

Learning Objectives

This three-day seminar provides Attendees with an overview of building enclosure testing concepts including:

• Discussions of air barrier enclosures from design to material selection and installation.
