In New South Wales, if you’re building a new home, undertaking renovations of $50,000 or more, or installing a pool or spa of more than 40,000 litres, you will need a BASIX (The Building Sustainability Index) certificate.
BASIX aims to create more comfortable and cost-efficient homes and additions, and requires evidence that your development plans meet energy sustainability targets.
It assesses three components of sustainable building design:
- Water – including basic landscaping details, fixtures, water storage and use, pools and spas
- Thermal Comfort – the thermal performance of the building fabric
- Energy (Green House Gas Emissions) – including hot water system, heating and cooling appliances, ventilation, lighting, energy used for pool and spa heating, alternative energy, etc.
