Empire Thermal Group provides accurate BASIX assessments and practical sustainability guidance for residential developments throughout New South Wales.
We work with architects, building designers, builders, developers and homeowners to create clear, coordinated pathways towards approval.
BASIX, the Building Sustainability Index, is the NSW sustainability assessment framework for residential development. It measures the proposed development’s water efficiency, energy use and thermal performance.
BASIX generally applies to all new residential developments in NSW, renovations valued above $50,000, and swimming pools or spas with a capacity of 40,000 litres or more.
Our team reviews the proposed design, completes the required assessment and prepares the commitments needed to support your development application or complying development certificate.

A successful BASIX assessment is not simply about entering information into an online tool. The commitments made through the assessment must be practical, achievable and accurately coordinated with the architectural plans.
Our role is to identify potential concerns early, recommend suitable improvements and ensure the final commitments align with the proposed design.

Water Efficiency
Water-efficient fixtures, rainwater collection, landscaping, irrigation and other water-use commitments.

Thermal Performance
The building fabric, insulation, glazing, orientation and shading that influence internal comfort.

Energy Use
The expected energy demand associated with lighting, appliances, building services and renewable-energy systems.

Heating and Cooling
The type, efficiency and configuration of the proposed heating and cooling systems.

Hot Water Systems
The proposed hot water system, energy source, efficiency and expected contribution to household energy use.

Construction Materials
The nominated building materials and information required for embodied-emissions reporting.

Our considered approach keeps the assessment process clear, coordinated and focused on achieving the right outcome.
