Do I need a BASIX certificate?
Applications (Development Application, DA, or Complying Development Certificate Application, CDC) to build or alter residential uses (houses and apartments usually) in NSW must be accompanied with a BASIX Certificate, provided that the cost of building is in excess of $50,000.
If the cost of altering the dwelling is less than $50,000 then no BASIX Certificate is required to be submitted with your application, however it is still possible to obtain a BASIX Certificate in order to ensure best practice with environmentally sustainable development objectives.
What aspects of the development are affected?
In order to calculate whether a development will pass the BASIX requirements, information is required with respect to,
- Building materials and finishes,
- Insulation type and values,
- Window types,
- Areas of landscaping including low water usage plants,
- Rain water tank size and its connection to landscaping, swimming pool, laundry and toilets,
- Shower head, tap and toilets water efficiency ratings,
- Type of hot water system,
- Air conditioning and other forms of heating and cooling,
- Energy efficient lighting,
- Ventilation of bathrooms, laundry and kitchen,
- Cooker type, and white goods,
- Photovoltaic (solar energy).
Whilst this list may seem daunting we can assist with advice and guidance as to how to achieve BASIX compliance.
Do I need a Thermal Rating Certificate?
BASIX certificates for new dwellings are usually accompanied by a thermal rating certificate (also referred to as a NATHERS, ACCURATE or BERS Pro rating). The aim of the thermal rating is to promote that dwellings are comfortable to live in from an energy point of view. A dwelling that requires minimal heating or cooling provides an improved way of life than would a dwelling that feels cold and requires significant heating.
The certificate will specify the building materials used in the project and will accompany the BASIX Certificate with your Development Application (DA) or Complying Development Application (CDC).
If you are altering your home and require a BASIX Certificate, you will not require a Thermal Rating Certificate, unless those works are very substantial and Council considers your building works to be result in a new dwelling.
