Building Enclosure Commissioning: Defining and Specifying an Effective BECx Scope

Many building enclosure failures begin with small issues or coordination gaps during design or construction that go unnoticed and undermine long-term building performance. Identifying enclosure issues early in the design and construction process reduced complications and cost compared to addressing problems after concealed conditional being to affect building building systems and occupants. Complex building enclosure assemblies and material transitions require careful design, precise construction, and coordination among multiple trades and manufacturers. An expert third part to review and verify performance goals in each project phase can help mitigate risk and maintain the owner’s quality and performance expectations. Without this oversight, project teams may overlook issues in enclosure design, installation, and materials interfaces that escalate into more significant problems.
