At giantA Pty Ltd, we specialise in BASIX certificate and NatHERS assessment services across New South Wales (NSW), helping homeowners, builders, and developers meet building sustainability index (BASIX) and energy efficiency standards.
Our energy rating consultants and sustainable architects Sydney ensure your project achieves full BASIX assessment compliance and delivers genuine sustainability outcomes.
What is
Understanding BASIX and Its Role in Building Sustainability
The Building Sustainability Index (BASIX), a key NSW Government initiative, ensures all residential developments and development applications meet energy and water efficiency targets.
Using the BASIX tool, our accredited BASIX assessors prepare a sustainability assessment for your design, measuring factors such as insulation, glazing, lighting, and appliance efficiency.
Your BASIX compliance certificate confirms that your project meets BASIX requirements for energy and waterconservation.
Our BASIX reports outline essential upgrades, from insulation specifications to renewable energy and thermal comfort improvements.
Example recommendations include:
- Solar or heat pump hot water systems
- Double-glazed windows for improved thermal comfort
- Efficient water fixtures and rainwater tanks
- Passive shading and lighting optimisation
Together, these measures align with BASIX standards and help lower greenhouse gas emissions.
NatHERS Assessment – Measuring Thermal Performance
The Nationwide House Energy Rating Scheme (NatHERS) evaluates your design’s thermal performance.
Our NatHERS assessors use tools such as AccuRate and FirstRate5 to generate a 0–10 star rating, showing how efficiently your building uses heating and cooling.
Since 2022, NCC Section J requires a 7-star minimum energy rating across Australia.
We optimise your design to meet these rules using passive solar principles, strategic glazing, and thermal comfort modelling.
When paired with BASIX compliance, a high NatHERS rating provides faster complying development certificate approvals and improved building sustainability outcomes.

How BASIX and NatHERS Work Together
In NSW, a NatHERS certificate fulfills the thermal component of BASIX compliance, simplifying your approval process.
This integration allows our team to optimise both energy and water performance while satisfying all BASIX assessment requirements.
Our Whole of Home energy efficiency reports analyse lighting, appliances, and renewable systems, ensuring long-term comfort and value.
This combined approach supports NSW’s sustainability goals and helps homeowners achieve true thermal comfort.
