FAQ

Q. What is the minimum energy rating for my state?

A. This varies per state. The current requirements by state are:

VIC; QLD; SA; TAS; ACT: 6 Stars

NT: 5 Stars (Class 1 and 10)

NSW: Minimum heating and Cooling load based on the Building Sustainability Index (BASIX). See further information below on BASIX.

Of course, the higher your star rating, the lower the energy requirements for heating and cooling your home.

Q. How is the price for an assessment determined?

A. The price is determined on a project by project basis and will be based on design complexity, house size, number of dwellings. Once we receive your house plans, a fixed price will be provided.

Q. What is the BASIX Certificate?

A. Introduced by the NSW Government, BASIX (Building Sustainability Index), ensures homes are designed to use less water and be responsible for fewer greenhouse gas emissions by setting energy and water reduction targets for houses and units.

It is a mandatory component of the development approval process in NSW under the Environment Planning and Assessment Act 1979. Therefore, all Develeopment Applications must be accompanied by a BASIX Certificate which confirms compliance with BASIX requirements.
