Buildings designed to use energy more efficiently can cut Australia's property sector energy emissions by more than 20 per cent, but the nation is being forced to wait for the government action required, asserts the Royal Australian Institute of Architects.
"Around 30-40 per cent of all primary energy is used in the design, construction and operation of buildings, with a corresponding rate of greenhouse gas emissions", said RAIA National President, Alec Tzanne.
"The design and building professions can help cut that energy use by more than 20 per cent but not without decisive and immediate action by the Federal Government."
Mr Tzannes said targets and incentives to reduce energy emissions - particularly in existing buildings - and an emission trading system that includes the building sector must be introduced as a matter of urgency.
"If the Federal Government is serious about arresting Australia's greenhouse emissions it needs to act now with measures and incentives for Australian industry and consumers to embrace energy-efficient technologies and design principles", said Mr Tzannes.
A UN report earlier this year found that more than one-fifth of present energy consumption per year could be saved by 2010 by applying more rigorous standards to new and existing buildings.
"Improving energy efficiency in new buildings - particularly new homes - doesn't always require advanced and expensive high-tech solutions. Smart design such as sun shading and natural ventilation, better insulation and using recycled building materials can help make a difference, and still allow us to maintain a high quality of comfort", said Mr Tzannes.
A more pressing challenge for Australia is to achieve energy efficiency in existing buildings.
"We especially need targets and incentives that will accelerate the refurbishment of existing buildings", Mr Tzannes said.
"Australians deserve a significant commitment now, not next year."
