How the BRRT works

How does the tool work?

There are many different factors that affect how resilient your property is to natural hazards. These include the weather hazard risk in your area, the characteristics of your site, the type of house and the building materials used.

The Building Resilience Rating Tool (BRRT) takes into account all the factors that are specific to your property and gives you a single resilience rating. It also provides you an opportunity to see which hazards your property is most susceptible to and which elements your house are negatively affecting your rating.

A little more on the technical side…

The BRRT draws from two different databases and user input that feed into an algorithm to produce ratings. The first database is the Building Resilience Knowledge Database (BRKD) which is a portal of information on the resilience of building products and materials to extreme weather events. The second database provides information about natural hazards and their probability of occurrence.  

BRRT Prototypes

Prototype I of BRRT started in 2010 and included inundation. Prototype II (the current BRRT) includes inundation and storm. The Australian Resilience Taskforce has a detailed plan for further improvements and refinements including the incorporation of information about two additional hazards - tropical cyclones and bushfire.

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.
