Sustainable construction for the future - the role of government in energy efficiency and sustainability in buildings

摘要

This paper will summarise the findings from a study that explored the link between dwellinguddesign, or type, and energy efficiencies in sub-tropical climates. An increasing number ofudgovernment and private sector development companies are initiating projects that aim touddeliver enhanced environmental outcomes at both sub-divisional and dwelling levels. Theudstudy used AccuRate, a new thermal modelling tool developed by CSIRO that responds toudthe need to improve ventilation modelling. The study found that dwellings developed inudconjunction with the Departments of Housing and Public Works have set the benchmark. Itudprovides a snapshot of the energy efficiency of a range of dwelling types found in recentudsubdivisions. However, the trend toward increasing urban densities may reduce theudlikelihood that cooling breezes will be available to cool dwellings. The findings are relevantudto regulators, designers and industry in all states interested in reducing the energy used toudcool dwellings in summer.
