Building Enclosure Commissioning (BECx)
NIBS Guideline 3
Building Enclosure Commissioning (BECx) is a quality assurance process that focuses on all aspects of the design, construction, operation, and maintenance of the building enclosure, which includes the roof, walls, windows, doors, foundation, and other elements that separate the interior from the exterior environment.
-
The process begins with design, where we review design documents to ensure the building enclosure meets the project’s performance requirements, such as thermal performance, air tightness, moisture control, and durability. This involves checking design specifications, detailing, and material selections for compliance with codes, standards, and best practices.
-
During the construction phase, we perform inspections on both mock-ups and in-situ conditions to ensure that practices align with the design intent and project specifications. This is the most critical phase of the project. Testing is performed to ensure things like air leakage, water penetration, and thermal performance meet the project requirements and perform as intended by the product manufacturers.

-
The final stage of the process is post-construction. Final inspections and testing are completed, product documentation is compiled including all findings, test results, and any corrective actions taken. Training is provided to the building operators and maintenance staff on maintaining the enclosure's integrity.
The overall goal of building enclosure commissioning is to avoid issues like energy inefficiency, moisture damage, air leaks, premature failures, and comfort problems, thereby ensuring the building performs as expected over its lifecycle, enhancing occupant comfort, reducing operational costs, and extending the life of the building materials. This process is particularly critical in high-performance or sustainable building projects where energy efficiency and environmental control are paramount.
