As Australian building codes evolve to mandate robust energy and moisture performance outcomes, airtightness testing has become a core compliance and quality assurance requirement for modern property developments. Aerotight delivers independent, ISO‑aligned airtightness testing and consultancy that gives you confidence – from design strategy to handover certification – while protecting brand reputation, operational energy performance, and regulatory compliance.
SCROLL
Leakage of uncontrolled air across the building envelope is a primary driver of energy inefficiency, occupant comfort issues, and moisture‑related defects in commercial and multi‑unit residential projects. Traditional design and simulation methods alone do not prove performance – empirical testing does.
Mandatory provisions in the National Construction Code (NCC) 2022, including Section F8 (Condensation Management) and verification requirements such as JV4 building envelope sealing, now require measured evidence that the building’s air barrier performs in situ to ensure compliance and to justify HVAC sizing.
Under NCC 2022, energy performance (JP1) and building envelope sealing (JV4) can be verified through measured air leakage results in accordance with AS/NZS ISO 9972 (blower door testing) – the internationally recognised method for building airtightness.
Airtightness performance impacts:
A measured result provides statutory building surveyors the quantitative evidence they demand to issue Occupancy Permits.
Aerotight conducts full building envelope airtightness testing in accordance with AS/NZS ISO 9972 using advanced blower door configurations and diagnostic tools - irrespective of building size or typology. This includes:
Early engagement with Aerotight transforms compliance from a late‑stage hurdle into a managed design strategy:
This “Aerotight Strategy” approach drastically reduces the risk of systemic defects and first‑test failures.
Airtightness testing plays a role in wider sustainability outcomes, including Green Star Design & As‑Built ratings. While Green Star air permeability testing is documented as a pathway to achieve up to one innovation point, the disciplined testing process is essential for high‑performance building certification.
This ensures your compliance evidence withstands scrutiny from regulatory authorities and certifiers alike.
Our Aerotight measures and reports integrate seamlessly into project QA/QC suites and regulatory sign‑off processes.
For modern property developments, airtightness testing is no longer optional. Developers must prove that their buildings meet energy performance targets, comply with construction standards, and deliver long-term durability. Aerotight provides independent, certified airtightness testing that protects your project from compliance delays, costly remediation, and reputational risk.
Why developers rely on Aerotight:
We provide the "Quantitative Evidence" that Building Surveyors now demand to sign off on modern high-performance builds.
Avoid the nightmare of "Leaky Building" headlines. Our testing provides a documented audit trail of build quality.
A verified airtight envelope allows you to specify smaller mechanical plants, often saving enough in capital costs to pay for the testing ten times over.
Should a dispute arise, our ATTMA-certified reports provide the forensic technical data needed to protect your position.
Hear directly from builders, architects, and project teams across Australia who trust Aerotight for accurate testing, smooth compliance, and dependable results on every project.
Our services align to AS/NZS ISO 9972, ATTMA methodologies and internationally accepted best practice protocols.
Ensure your next development delivers compliance, performance, and structural integrity with confidence. Aerotight testing, strategy and verification services give you the clarity and evidence to meet regulatory demands and protect your investment.
