Why is a post-construction audit necessary for air barriers?

A post-construction audit is vital for air barriers primarily to ensure compliance with design intent and code requirements. This process involves a thorough examination of the installed air barrier system to verify that it has been executed according to the specifications outlined during the design phase. Additionally, building codes often dictate specific performance criteria that air barriers must meet, such as air leakage rates and insulation values.

By conducting a post-construction audit, stakeholders can identify any deviations from these requirements and ensure that the air barrier functions as intended. This step is crucial not only for compliance but also for the long-term performance of the building, as ineffective air barriers can lead to problems such as energy loss, moisture intrusion, and overall decreased building efficiency.

Other options, while they may pertain to aspects of building performance or aesthetics, do not capture the primary purpose of the post-construction audit as it pertains to air barriers. Aesthetic considerations do not impact the essential function of the barrier, while cost-efficiency and overall building performance are important but secondary to the immediate need for compliance with established standards and codes.
