Heat wave risks and residential buildings

Abstract

The modelling of the global climate over the 21st century indicates various changes including sea level rise and an overall warming effect of between 1.4 and 5.8 °C. The local effects of these long term global changes are currently being considered. It is probable that more severe and frequent heat waves will pose an increasing risk to the occupants of buildings in Australia and regions around the world. Recent heat waves have caused significant morbidity and mortality as well as a range of disruptive effects in the urban environment. This paper reports on a research project that aims to determine possible design options for adapting residential buildings to more severe heat waves. The focus of the research is on particular residents who are the more vulnerable in the community in terms of both health and financial resources. The paper reviews past and future impacts of heat waves and available mechanisms for dealing with their effects. The paper concludes by suggesting a number of design options that can be considered to adapt dwellings to more severe heat wave conditions.
