A BASIX Certificate is required for all new and altered* residential developments in NSW and forms part of the development application process in NSW.
BASIX, or the Building Sustainability Index, is a NSW Government initiative designed to encourage sustainable residential development within NSW. The aim of BASIX is to reduce greenhouse gases and water consumption in new and renovated residential developments and encourage the construction of residential developments with good thermal comfort performance.
Our Team and/or accredited in-house Assessor will complete a preliminary BASIX assessment of your project and will provide advice on what is required to achieve compliance with each section: water conservation, thermal comfort performance and energy efficiency.
* Applicable to alterations that cost $50,000 or more.
A NatHERS Certificate is required for certain new residential developments that do not fit within the criteria of the Thermal Comfort DIY option in BASIX.
The Nationwide House Energy Rating Scheme, aka NatHERS, is star rating system that rates the thermal comfort performance of a residential design – the higher the star rating, the higher the thermal comfort performance, which equates to a more energy efficient dwelling.
The thermal comfort performance of a dwelling is determined by assessing the dwelling’s location and orientation, construction materials, roof design, window size, style and orientation, placement of living and bedrooms, overshadowing by neighbouring developments and/or trees, cross ventilation and shading.
