How is the performance of an air barrier evaluated within the building enclosure commissioning process?

The performance of an air barrier is evaluated as a subsection of the Building Enclosure Commissioning (BECx) process. This integrated approach is critical because air barriers are essential for enhancing the energy efficiency and overall performance of the building. Including the evaluation of air barrier performance within the broader commissioning process ensures that the building enclosure is fully addressed, allowing for a systematic approach to assessing its performance under actual conditions.

Evaluating the air barrier during the commissioning process involves various tests and assessments that help identify any potential leaks and ensure that the air barrier is functioning as intended. This process emphasizes the importance of quality control and verification at each stage of the construction, as it can help prevent issues such as condensation, air leaks, and mold growth, which could arise if these elements are evaluated only after construction is completed.

This approach highlights the proactive nature of quality assurance within the commission, rather than relegating the assessment to audits alone or deferring it until after the building is fully constructed. It underscores the necessity of incorporating air barrier evaluation at a stage when adjustments can still be made, thereby enhancing the overall success of the building’s performance and longevity.
