- Description
- The intensity of tropical cyclones and severe storms are likely to increase due to climate change. Brisbane and the northeast coast of Queensland in Australia are regions where design wind specifications may be inadequate under either current or likely future climate conditions are particularly vulnerable. An appropriate adaptation strategy may be one that increase wind classifications for new houses leading to reduced vulnerability of newconstruction.The present paper will assess the damage risks, adaptation costs and cost-effectiveness of this adaptation measures for residential construction in the Queensland cities of Cairns, Townsville, Rockhampton and Brisbane assuming time-dependent changes in frequency and intensity of cyclonic and non-cyclonic winds to 2100. Loss functions were also developed for direct and indirect losses. It was found that increasing design wind loads for new houses in Brisbane and South East Queensland will lead to a mean net benefit (net present value NPV) of up to $10.5 billion by 2100 assuming a discount rate of 4%. The benefits are highest for Brisbane due to its large population and high vulnerability of existing residential construction, and have 90-100% likelihood to achieve a net benefit by 2100.
