BASIX & NatHERS
The Building Sustainability Index (BASIX) sets sustainability targets for water and energy as well as minimum performance levels for the thermal comfort of the proposed development. These targets are expressed as a percentage. They apply to all new residential dwelling types and are part of the development application process in NSW. The BASIX requirements are for water and energy usage and thermal comfort performance.
To approve such developments, the consent authority requires evidence that the development plans meets the BASIX requirements.
Because every home is different, site orientation, climate zone, glazing style and position, number of bedrooms and appliance types are all factors that impact the NatHERS result. Some elements of your home may need items added or upgraded to suit these BASIX and or NatHERS requirements and compliance. This information will be determined as we are preparing for your council lodgements.
The Nationwide House Energy Rating Scheme (NatHERS) measures a home’s energy efficiency to generate a star rating. The higher the star rating, the less energy needed to heat and cool the home. NatHERS Assessors currently use the house plans and building specifications of a home to input data into a NatHERS accredited software tool to estimate the amount of heat that needs to be added or removed to keep that home comfortable all year round. The NatHERS tools then generate a certificate and NatHERS star rating out of 10. This star rating measures the home’s thermal performance, based on its structure, design and materials. The NatHERS certificate allows the assessor to complete further analysis of the structure and design.
Water - designed to reduce your water usage, through water reuse.
Energy - designed to reduce your electrical consumption by installing energy efficient appliances.
Thermal - designed to ensure that new homes constructed, expend less energy using construction materials.
