BASIX Report


What is a BASIX Report?

A BASIX Report is a draft documentation of the information which will be reflected on an actual BASIX Certificate. We provide a BASIX Report prior to provision of a formal BASIX Certificate in order to confirm that all details and BASIX specification meet the clients’ preferences and reflects the development design intentions accurately. This approach gives us the ability to change details and requirements to fine tune the BASIX Certificate that will be lodged to the council.

Please note that this BASIX Report is not a certified document and therefore you cannot use it to lodge your development through the council. You can find this indicated in the bottom left hand corner of the report where it states “This is not a valid certificate.”

Checking your BASIX Report

When you are entering the details asked of you into the checklist which we have provided to you for preparation of the draft BASIX Report, you must ensure that you have provided all of the correct general information regarding your new or existing development. You can double check that all information is correct when receiving the draft BASIX Report from us for your preview and confirmation. The most important sections to check is details such as; the development’s address, plan type and number, lot number, section number and the local government you are planning to lodge your BASIX Certificate to. If you receive a BASIX Certificate and these are found to be incorrect, you will be rejected by the council as it does not reflect or reference the development correctly and to change these details we must contact the NSW Development of Planning, which is a very lengthy and difficult process and it can cause submission delays.

Another point to remember is that thermal comfort, conditioned and unconditioned floor area, dwelling/unit numbers and number of bedrooms is the information provided by NatHERS thermal comfort software. As a result the areas which are used for creating of the BASIX Report are not necessarily equal to the areas which are being measured on the plans using architectural considerations and in many situations there are noticeable differences.

Lot number field of the BASIX Report can be up to 6 characters long only and plans numbers can be up to 7 characters long. Where more than one Lot number or Plan number exists for a particular development please select only one as a representative of the project. This will not affect your submission to the council as this is being considered with the rest of documents of the development and it is also a limitation of the tool which is being provided by the NSW Department of Planning itself.

Passing and complying to BASIX Assessment Tool

The information required for different types of BASIX Reports can be very different. The commitments set out of the BASIX reports regulate how the proposed development is to be carried out. It is a conditioned of any development consent drafted, or complying development certificate issued, for the development that the BASIX commitments are complied with.

Each BASIX Report is divided up between three sections which you must pass: Water Efficiency, Thermal Comfort and Energy Efficiency. If the development does not pass the minimum requirements of the BASIX scores, you will be unable to receive a BASIX Certificate. In these commitments “applicant” means the person carrying out the development. The applicant must ascertain that each dwelling, building and common room are listed in the BASIX Report, on the plans accompanying any development application, and on the plans and specifications accompanying the application for a construction certificate/complying development certificate for the proposed development using the same identifying letter or reference as is given to that dwelling, building or common area. If the proposed development involves the erection of a building for both residential and non-residential purposes, commitments in the BASIX Report which are specified to apply to a “common area” of a building or the development, apply only to that part of the building or development to be used for residential purposes. If this BASIX Report lists a central system as a commitment for a dwelling or building, and that system will also service any other dwelling or building within the development, then that system need only be installed once. If a star or other rating is specified in a commitment, this is a minimum rating. All alternative water systems to be installed under these commitments must be installed in accordance with the requirements of all applicable regulatory authorities. Please note that NSW Health does not recommend that stormwater, recycled water or private dam water to be used to irrigate edible plants which are used for consumed raw, or that rainwater be used for human consumption in areas with potable water supply.
