The Energy section of BASIX sets energy use standards to reduce the greenhouse gas emissions of all new residential dwellings.
The energy use standards are specified in Table 1 of Schedule 1 of the State Environmental Planning Policy (Sustainable Buildings) 2022. The percentages in the table represent a reduction in greenhouse gas emissions compared to the benchmark emissions and they depend on the climate zone and development type. The benchmark is 3,292 kilograms of carbon dioxide per person per year, which was the average for pre-BASIX homes.
To see the energy use standard that applies to your BASIX project, please refer to this calculator.
Energy consumption and savings is assessed on:
- Hot water systems
- Heating and cooling
- Ventilation
- Lighting
- Pools and spas
- Alternative energy sources
- Other energy uses
- Central systems
