Our commitment to our customers and the industry makes the difference

From the foundation to the highest apex of the roof, the building envelope encompasses all aspects of a building’s structure. A structurally sound building envelope is critical to ensure safety and optimize a building’s life expectancy and reduce reparation costs. At the Building Envelope Science Institute (BESI), our experts train and certify industry professionals using nearly 30 years of building envelope knowledge and field experience.

“I attended BESI training and was impressed by the cogent and entertaining presentations that sharpened and consolidated my knowledge regarding building envelope issues and our industry. BESI takes no point of view, but recognizes the economic costs of not being educated and using best practices in building envelope integrity. I also was pleased at the geographic and professional background diversity of the attendees. Their perspectives provided another level of education for me and my colleagues.”

Bruce J. Schulte, J.D, CFRE, BET-1The Garrett McKenzie Environmental Group Inc.

“The seminar was intense, but very educational as Scott “Spiderman” Mullholland presented the material in an energetic and thought provoking manner. I feel fortunate to have been in the first group to go thru the training and look forward to attending future BESI training sessions.”
