Green Star is Australia’s leading sustainability rating system, developed by the Green Building Council of Australia (GBCA). It independently assesses the environmental performance of buildings, fitouts, and communities across their entire lifecycle.
It’s not just a rating, it’s a benchmark for high-performance, future-ready buildings that deliver better outcomes for occupants, owners, and investors.
In a market where “Net Zero” is the new standard, Green Star certification is the key to increasing asset value and meeting ESG (Environmental, Social, and Governance) goals.

Here’s the reality most project teams underestimate:
You cannot achieve high Green Star ratings without controlling air leakage.
Uncontrolled air infiltration directly impacts:
• Energy performance modelling
• HVAC efficiency
• Indoor air quality
• Moisture and condensation risk
Green Star places strong emphasis on building performance outcomes, not just design intent. That means your building must actually perform as expected in real-world conditions.
Without verified airtightness:
• Energy targets are missed
• Commissioning fails
• Certification points are lost
Green Star includes four core certification pathways:
Design and construction of new builds or major refurbishments
Fitouts for commercial spaces
Design and construction of new builds or major refurbishments
Large-scale precinct developments
Each pathway evaluates sustainability holistically across environmental and operational metrics, encouraging innovation and measurable performance improvements.
To achieve a high Green Star rating (4, 5, or 6 Stars), a building must perform efficiently in the real world, not just on paper.
Aerotight provides the specialized membranes, tapes, and sealing systems required to create a continuous thermal envelope. Without a high-performance seal, even the best insulation fails. Aerotight ensures your building remains airtight, moisture-protected, and energy-efficient.
The Aerotight Impact: By eliminating uncontrolled air leakage, our systems significantly reduce the load on HVAC systems, directly contributing to Energy Use credits and helping your project move toward Positive certification.
The Aerotight Impact: Our sealing solutions prevent drafts and manage moisture vapor. This eliminates the risk of interstitial condensation and mold growth, ensuring a healthier, more comfortable indoor environment that meets strict IEQ criteria.
The Aerotight Impact: Our products are engineered for the harsh Australian climate. By protecting the building structure from moisture damage and rot, Aerotight extends the life cycle of the building fabric, aligning with Green Star’s Responsible and Resilient pillars.
We understand local building codes (NCC) and the specific challenges of the Australian environment.
Our membranes and tapes are tested for compatibility and long-term performance.
We provide the technical data and documentation you need to streamline your Green Star submission process.
We don't just sell products; we provide the technical guidance to ensure they are installed correctly to meet your Blower Door test targets.

Green Star is Australia’s leading sustainability rating system, assessing the environmental performance of buildings, interiors, and communities. It verifies that a project meets strict standards for energy efficiency, indoor environment quality, and overall sustainability.
While not always explicitly mandatory, airtightness testing is often critical to achieving targeted credits, especially those related to energy performance, commissioning, and indoor environmental quality. Without it, meeting performance benchmarks becomes significantly harder.
Most commercial projects target:
Your target depends on project goals, budget, and ESG requirements.
Testing should be done in three key stages:
Leaving testing too late increases cost and risk.
If a building fails:
This can lead to project delays and added costs, which is why early testing is critical.
Aerotight provides:
We ensure your results are accurate, defensible, and submission-ready.
Yes. Through the Green Star Performance pathway, existing buildings can be rated based on operational performance. Airtightness improvements can play a key role in boosting energy efficiency and overall ratings.
Green Star is commonly used for:
Aerotight focuses on one thing: verifiable building performance.
We help you:
Airtightness is a primary driver for the Energy Use and Positive categories. By minimizing uncontrolled air leakage, a building requires significantly less energy for heating and cooling. This reduction in operational carbon is essential for achieving higher 5 and 6-star ratings.
Aerotight solutions primarily contribute to credits within Energy Use, Indoor Environment Quality (IEQ), and Responsible Building Materials. Specifically, they help meet targets for thermal comfort, energy efficiency, and moisture management.
While the NCC sets minimum standards, many high-performance Green Star projects mandate Blower Door testing to verify that the design's airtightness targets have been met in reality. Aerotight systems are designed to help projects pass these rigorous air permeability tests on the first attempt.
A seal created with Aerotight membranes prevents external pollutants, allergens, and dust from entering the building. Furthermore, it eliminates "cold spots" and drafts, ensuring a stable, high-quality thermal environment for occupants, which is a key metric in the Green Star IEQ category.
Yes. By protecting the building's structural envelope from interstitial condensation and moisture-related rot, Aerotight extends the building's lifespan. This durability reduces the need for premature repairs or resource-heavy replacements, aligning with Green Star’s focus on long-term resilience.
Yes, our sealing tapes and membranes are selected for their low-emission profiles. This ensures they do not off-gas harmful chemicals, helping your project meet strict indoor air quality standards and material transparency requirements.
The National Construction Code (NCC 2022/2025) provides the "floor" for building performance, while Green Star represents the "ceiling." Aerotight solutions are engineered to exceed standard NCC requirements, bridging the gap between basic compliance and world-leading sustainability.
Our vapor-permeable membranes allow the building to "breathe" while remaining airtight. This prevents moisture from becoming trapped within the wall cavity - a critical factor in preventing mold and ensuring the building meets the Healthy and Resilient pillars of Green Star.
Don’t leave compliance to chance.
