DocAir Air Barrier Auditing (ABA), ABAA Certified Professionals
Air infiltration and exfiltration are among the largest, most overlooked drivers of energy waste and comfort problems in commercial buildings. An air barrier audit quantifies exactly how much air is moving through your building envelope, and identifies every gap, penetration, and failed seam that is responsible.
DocAir is ABAA-certified, Nashville-based, and has been delivering science-based building diagnostics since 2002. If your commercial property is in Nashville, find the right team.

Why ABAA Certification Matters for Your Project
Not all air barrier inspectors are created equal. Only ABAA-licensed field auditors are authorized to conduct official ABAA Quality Assurance Program audits, and the distinction matters for any project where compliance documentation is required.
The ABAA QAP was specifically designed to manage the risks that occur during air barrier installation, including the risk that an installed system that looks correct is not performing correctly. DocAir's auditors hold ABAA field auditor certification alongside a portfolio of complementary credentials, including LEED, HERS, and expertise in mechanical engineering. When an audit report bears the ABAA certification, it carries weight with designers, general contractors, code officials, and building owners alike.

Frequently Asked Questions
Is an air barrier audit required by the Tennessee building code?
Tennessee's commercial energy code follows ASHRAE 90.1, which requires a continuous air barrier for commercial buildings in Climate Zones 4 and above. Nashville falls within Climate Zone 4. While a formal ABAA QAP audit is a performance-based option rather than a prescriptive mandate in all cases, many designers and general contractors now require it as a condition of contract. Projects pursuing LEED certification also require building enclosure commissioning that includes air barrier verification.
How does air barrier auditing differ from a blower door test?
A blower door test measures total building air leakage as a single number, it tells you how leaky the building is. An air barrier audit goes further: it inspects the installation quality of the air barrier assembly itself, identifies specific locations and causes of air leakage, verifies material and application compliance with specifications, and produces a QAP-compliant documentation package. For commercial buildings, both are often used together for a complete picture.
What happens if the audit finds deficiencies?
We provide air barrier testing and verification services, documenting any installation issues as part of their advisory process and communicating them to the responsible contractor for correction before construction moves forward. DocAir's role is to provide objective documentation, not to perform the repairs, which ensures there is no conflict of interest in the audit findings.
