The Bottom Line – household impacts of delaying improved energy requirements in the Building Code [PDF 3.81 MB]
Australia has the potential to strengthen residential energy standards in the Building Code and cut heating and cooling energy use by up to 51 per cent, according to a new report released today by ClimateWorks Australia and the Australian Sustainable Built Environment Council (ASBEC).
The ClimateWorks and ASBEC report highlights that energy requirements in the Code were last updated in 2010 and are next due to be updated in 2019, which is proposed to include improvements to the requirements for housing. These are a good start, but there is no proposal to strengthen the required level of energy efficiency for homes. The report stresses that by failing to act now, we will be building to 2010 standards all the way to 2022, locking in higher emissions and energy costs.
However, implementing these changes now could deliver Australians more comfortable homes plus savings of up to $150 per household a year on energy bills, more than offsetting additional capital costs. Changes could also cut emissions by around 10.8 million tonnes to 2050 - the same amount Loy Yang B coal-fired power station emits annually - and reduce stress on the electricity grid.
