BASIX or Building Sustainability Index is a mandatory sustainability scheme for residential developments in New South Wales.  BASIX overrides the NCC and assessments are conducted online using the Basix assessment tool to achieve sustainability targets for water consumption, thermal comfort rating and energy usage.

Accelerate staff are ABSA and BDAV accredited and can provide simulation method assessments for the thermal comfort section. This method of assessment usually results in less construction requirements compared to the Rapid and D.I.Y methods.

Queensland Residential

  • Single and multi-storey dwellings
  • Townhouses, duplexes and triplexes
  • Units and apartments
  • Re-locatable and modular homes

The Queensland Development Code (QDC) allows several methods of assessment to achieve compliance, the two of which that are most common are:

  1. A Deemed-to-Satisfy (DTS) assessment which involves checking that each individual aspect of the building meets the minimum requirements outlined in the National Construction Code – Volume 2.
  2. A NatHERS software assessment that achieves a minimum 6 star rating by simulating the design to calculate the overall heating and cooling loads over an entire year.

We will determine which method of assessment will achieve the best desired outcome and issue a detailed report that verifies compliance as well as list any additional construction requirements.


  • Offices
  • Retail
  • Aged Care
  • Childcare & Schools

All commercial buildings (class 3-9) must be assessed against Section J of the NCC-Volume 1.

Accelerate provide Deemed-to-Satisfy (DTS) reports for any size and type of commercial building throughout Australia. This involves reviewing each applicable performance requirement from Section J and providing a certificate that indicates how compliance is achieved for each relevant building element.

Advice and Design Recommendations

Accelerate provide independent advice both during and post construction. We also offer passive design recommendations prior to architectural plans being drawn.

Did you know that approximately 40% of household energy is used for artificial heating and cooling to achieve thermal comfort. Designing a house for the climate will ultimately reduce the need to switch on air-conditioners, which will reduce those electricity bills.
