BASIX Certificate online index is a mandatory sustainability scheme for entire NSW with the purpose of certifying all developments to be designed reducing the use of potable water and to produce less greenhouse gas emissions. The BASIX tool is used to calculate the house or unit’s energy and water scores based on a range of data, including size, location, design features and fixtures.
The BASIX Certificate is an NSW Government is a certification that the proposed development is properly assessed and ensures to meet the set standards of the BASIX index for sustainable building. It is comprised of Four sections: General Description of the Project, Water Efficiency commitments, Thermal Comfort Commitments, and Energy Efficiency commitments that need to pass specific requirements.
Basix is designed to contribute to energy efficiency and to meet the building code of Australia. As part of the commitment, the development must use the least amount of potable water and be responsible for fewer greenhouse gas emission. It can be achieved and obtained through proper location and siting, proper ventilation, the use of energy rating fixtures and lighting devices, house fabric complying the standards of thermal performance, proper use of insulation, and proper window positioning, glazing, and shading.
BASIX encourages you to reduce your energy use and greenhouse gas emissions through the following strategies:
Hot water systems – reducing the demand for hot water (by improving water efficiency) and meeting the demand with less greenhouse-gas-intensive water heaters
Heating and cooling – reducing the heating and cooling demand (by improving thermal comfort performance) and meeting the demand with less greenhouse-gas-intensive appropriate heating and cooling systems
Ventilation and exhaust – using natural ventilation where appropriate, and reducing the operation of mechanical ventilation with suitable controls
Lighting – using direct natural lighting where appropriate and energy-efficient lighting
Pools and spas – choosing less greenhouse-gas-intensive water heating and pumping systems
Alternative energy sources – such as photovoltaics, wind turbines and cogeneration
Other energy uses – choosing less greenhouse-gas-intensive cooking facilities, refrigeration, clothes drying and appliances (appliances are an option in multi-dwellings only – not single dwellings)
Central systems (in multi dwellings only) – central hot water, central heating, central cooling, lifts, saunas and other measures
