A BASIX certificate is required for new dwellings, multi-unit apartment buildings and row houses as part of the development application process.

It may also be required for alterations and additions valued over $50,000, or for swimming pools with a capacity greater than 40,000 litres.

BASIX is the NSW Government's Building Sustainability Index, which sets requirements for thermal comfort, water efficiency and energy performance.

Professional BASIX assessors like Positive Eco can help assess your project and guide you through the compliance and certification process.

For a typical project home, assessment fees start from $580, including GST, BASIX and NatHERS certificates.

Final pricing may vary depending on the project size, complexity and assessment requirements.

At Positive Eco, we prioritise fast turnaround times to help keep your project on schedule.

We can accommodate urgent assessments and rush jobs, and may arrange weekend work when required to meet project deadlines.

A NatHERS assessment can be used to demonstrate compliance with the thermal performance component of BASIX.

It offers flexibility by allowing improvements in one building element to compensate for performance limitations in another.

For example, rather than reducing glazing areas to meet thermal requirements, a NatHERS assessment may allow additional ceiling insulation or other design improvements to achieve compliance.

A complete set of architectural drawings and project documentation is generally required, including:

• Architectural floor plans
• Site plans
• Building elevations
• Window and glazing schedules
• Wall and construction details
• External finishes and materials schedules

Absolutely. An experienced BASIX assessor can help identify practical and cost-effective pathways to compliance.

At Positive Eco, we work closely with clients to understand their project requirements, design preferences and constraints, then recommend suitable compliance solutions.
