Your BASIX Compliance Made Simple
Developing a high-rise apartment building in New South Wales? You’ll need a BASIX Certificate that demonstrates compliance with the NSW Government’s sustainability targets for water, energy and thermal performance before lodging your Development Application (DA). At BASIX Certificates, we specialise in high-volume, multi-storey assessments—delivering fast, accurate, and scalable compliance solutions.
We work closely with architects, project managers, and developers to simplify complex compliance across every level of your apartment building, ensuring every unit and shared system is BASIX certified and DA-ready.
Why High-Rise Apartments Need BASIX Certification:
Under NSW planning policy, all residential dwellings, including those within high-rise developments, must meet the sustainability requirements of the Building Sustainability Index (BASIX). This includes thermal comfort modelling, energy efficiency measures, and water-saving infrastructure across both private and shared spaces.
Our team understands the intricacies of multi-storey developments and can advise on the best approach—whether it’s grouped or unit-by-unit assessments or a combined BASIX and JV3 pathway for mixed-use buildings.
What’s Assessed in a High-Rise BASIX Report:
-
Unit orientation, insulation and thermal zoning
-
Shared energy systems (e.g. hot water, lighting, HVAC)
-
Individual and common area water-saving systems
-
Solar power and smart metering integration
-
Efficient appliances and lighting for multi-unit use
