Passive House (Passivhaus) projects represent the highest standard of building performance in Australia – where airtightness is not optional, but mission-critical.
At Aerotight, we don’t just test buildings, we Aerotight projects from concept to certification, ensuring your development achieves the stringent 0.6 ACH50 requirement and aligns with ISO testing protocols, NCC pathways, and high-performance design outcomes.
SCROLL
Passive House buildings rely on a controlled, airtight envelope to deliver ultra-low energy consumption, superior indoor air quality, and long-term durability.
To meet certification, buildings must achieve:
Without verified airtightness, Passive House performance fails at the fundamental level – impacting energy modelling, thermal comfort, and compliance outcomes.
Aerotight Insight:
Most Australian homes average ~15 ACH50 – over 25x leakier than Passive House requirements . This is why Passive House demands a completely different construction and verification approach.
We implement a whole-of-project Aerotight Strategy – not just final testing.
Our calibrated blower door systems can test everything from small residential builds to large commercial structures, delivering reliable results every time.
Outcome: Reduced rework, predictable compliance, and certification confidence.
All Aerotight testing aligns with:
This is also the same standard referenced within NCC verification pathways.
All Aerotight testing aligns with:
For Class 2 and residential developments, airtightness testing can support performance solutions and JV4 verification pathways.
For mixed-use and multi-residential buildings:
