Australian Standards 3959 – Construction of Buildings in Bushfire Prone Areas and the different Wildland Urban Interface (WUI) Building Codes in the U.S., CA Building Code, IWUIC, NFPA, etc. are all based on similar research. Embers are 80-90% of the cause for building loss, followed by radiant heat and direct flame.

A homeowner cannot control the land and vegetation outside of their property boundary. Therefore, codes make us look to what we can control. As a building code generally take years to write and update, we now look to National and State Fire Authorities for Best Practice.
