Building Resilience Rating Tool

The Building Resilience Rating Tool (BRRT) is intended to rate the resilience of your home to common extreme weather hazards. What is resilience?

The Building Code of Australia sets minimum standards for construction across Australia, ensuring that homes are safe, sustainable, accessible and cost effective. However, the minimum standards do not include measures to ensure that the building will be resilient (not suffer damage) during extreme weather events in your location. Low resilience buildings are inherently brittle to extreme weather events, suffering damage and economic loss during floods, fires, storms etc. A building that is designed  to be resilient to weather hazards is likely to save you money as it will suffer less damage from these events.  A rating from the BRRT will provide you with information concerning which parts of your home are most at risk. You will be able to explore alternative building elements to see how you can increase your resilience.

For information on how the tool works and a glossary see how the BRRT works.

Current Status of the BRRT Program -  Beta testing BRRT 2.0

The ICA has been working on increasing the resilience of the built environment for a number of years and has been developing the BRRT since 2010. The BRRT Development Team has engaged with over 120 stakeholders; extensively researched the resilience and durability of building materials; and developed calculations and formulations to form the basis of the BRRT. The methodology of the BRRT has been supported and informed by an Expert Advisory Group.

Whilst the BRRT Development Team has used the best available data and information in the BRRT calculations, it is acknowledged that there are ongoing advancements in data and we are continually looking at ways to improve the usability and accuracy of the tool.

Curent BRRT Version - BRRT 2.0 has been released for beta testing by relevant experts and stakeholders. If you havent already, you can apply to be considered as a beta tester by registering below.

The ICA intends to release a public version of BRRT 2 once we have addressed feedback from stakeholders and refined user inputs.The general development path for the BRRT is:

  • BRRT 1  Inundation (retired)
  • BRRT 2  Inundation, Storm (in beta testing)
  • BRRT 3  Inundation, Storm, Cyclone
  • BRRT 4  Inundation, Storm, Cyclone, Bushfire
  • BRRT 5  Inundation, Storm, Cyclone, Bushfire, Earthquake
  • BRRT 6  Inundation, Storm, Cyclone, Bushfire, Earthquake, Extreme Heat

The current version of the BRRT is focussed on stand-alone residential property. Future development will incorporate strata and commercial construction types.

What is the difference between this rating and supplier ratings?

The rating you see at the top of the page is the resilience rating of the generic class of building material to a particular hazard. A supplier rating is particular to a specific supplier product. For example, clay bricks may have a resilience rating of '3' to inundation but a supplier may have made specific improvements to their bricks and may be able to achieve a resilience rating of '5' for their clay brick.
