BASIX Benchmarks:
To determine water and energy targets, the average benchmark for per person consumption of potable water and greenhouse gas emissions within the NSW residential sector is calculated.
- Water – the NSW benchmark per person is 90,340 litres per year.
- Energy – the NSW benchmark per person is 3,292 kg of CO2-e per year.
BASIX Targets:
The performance targets set by the NSW Government include:
- up to a 40% reduction in potable water consumption
- up to a 40% reduction in greenhouse gas emissions and
- minimum performance levels of thermal comfort.
The BASIX certificate benchmarks of water and energy are both measured on a per capita basis, including:
- Water – the average NSW consumption of potable water from the residential sector.
- Energy – the annual average NSW greenhouse emissions from the residential sector.
