SCROLL
In Australia’s evolving construction landscape, airtightness is no longer optional – it is a measurable, compliance-driven performance requirement.
For new home builds and residential developments targeting NCC compliance, Green Star certification, or high-performance outcomes, airtightness testing is critical to achieving verified building envelope performance.
At Aerotight, we don’t just test – we Aerotight projects strategically, embedding airtightness into design, construction, and commissioning to ensure measurable, compliant outcomes aligned with AS/NZS ISO 9972 testing standards and NCC verification pathways.
The NCC explicitly requires building envelopes to be sealed against air leakage as part of its energy efficiency objectives .
Aerotight ensures these risks are addressed early through Aerotight design reviews, detailing strategies, and performance validation testing.
Under NCC 2022 Section J, airtightness plays a direct role in achieving compliance with energy efficiency performance requirements.
Aerotight applies a compliance-first methodology, ensuring your project aligns with:
This is not theoretical compliance – this is measured, certified performance.
For developments targeting Green Star Design & As Built certification, airtightness testing is a direct pathway to sustainability credits.
Aerotight has delivered industry-first Green Star airtightness testing projects in Australia, working collaboratively with:
We don’t just test – we Aerotight Green Star strategies, aligning airtightness targets with cost, constructability, and certification outcomes.

1. Aerotight Design Strategy
2. Aerotight Construction Measures
3. Aerotight Verification Testing
We position airtightness as a performance asset, not a compliance burden.
Airtightness is one of the few building performance metrics that can be objectively measured and verified.
The difference between design intent and real-world performance comes down to one thing:
Testing. Validation. Accountability.
Aerotight ensures your residential project is not just designed to perform –
It is proven to perform.

Hear directly from builders, architects, and project teams across Australia who trust Aerotight for accurate testing, smooth compliance, and dependable results on every project.
Airtightness testing measures how much uncontrolled air leaks through a building envelope. For new homes, it ensures the design intent is achieved—improving energy efficiency, comfort, and compliance with NCC requirements. Aerotight testing provides measurable proof of performance, not assumptions.
While not always mandatory prescriptively, the NCC (Section J) requires buildings to minimise uncontrolled air leakage. Testing is commonly used as a verification method (J1V4) to demonstrate compliance—especially for performance-based designs.
Aerotight conducts blower door testing in accordance with AS/NZS ISO 9972, the internationally recognised standard for measuring building air permeability. This ensures results are accurate, repeatable, and certifiable.
Typical NCC reference levels for apartments (Class 2) are around ≤10 m³/hr·m² @ 50Pa, but project targets vary depending on:
Aerotight helps define project-specific targets aligned with compliance and performance goals.
For best results, Aerotight recommends a staged approach:
This reduces risk, cost, and rework.
Yes. Airtightness testing can contribute to Green Star credits by verifying building performance. Aerotight works with project teams to align airtightness outcomes with Green Star pathways and documentation requirements.
Typical leakage points include:
Aerotight identifies and addresses these through targeted Aerotight measures and on-site diagnostics.
Yes - positively, when designed correctly. Airtight buildings reduce uncontrolled air infiltration, allowing mechanical ventilation systems to deliver filtered, controlled fresh air. Aerotight ensures airtightness works in balance with ventilation design.
Improved airtightness reduces heating and cooling losses, resulting in:
Lower energy consumption
Reduced operational costs
More stable indoor temperatures
Aerotight testing ensures these performance benefits are actually achieved in the built outcome.
Aerotight goes beyond testing by providing:
Aerotight design strategies during early project stages
On-site guidance and inspections
Detailed reporting aligned with NCC and ISO requirements
We work as a performance partner, ensuring airtightness is designed, built, and verified - not left to chance.
Whether you’re delivering:
Aerotight will define, implement, and verify your airtightness strategy with precision.
Aerotight your next project – and make performance measurable.
