There are calls for changes to the nation's building code to ensure homes are heat stress resistant in summer.
A study has found new 'energy efficient' homes can actually be less resistant to heat than older double-brick homes.
As a result, Australian's are becoming more reliant on air-conditioning, driving up power prices and putting people's health at risk.
A rapid review on green-rated office buildings, and their operational energy use, found that the conclusions of six studies ranged from the certified buildings performing worse, similarly or much better than the non-certified buildings in terms of energy usage intensity. Two...Read more
Industry misconceptions around high cost and poor market interest in energy efficient homes continue to obstruct the mass adoption of low carbon housing. Josh’s House demonstrates that low carbon housing is accessible and cost effective. The Star Performers series showcases how...Read more
Research identifies that home design needs to considers both energy efficiency and heat stress resistance. Currently, NatHERS only focuses on energy efficiency. If the building codes are not modified, then house designs which only focus on NatHERS could adversely impact people's...Read more
In Australia, heatwaves are the deadliest natural hazard and a major driver of peak electricity demand. The disproportionately high peak demand increases electricity prices, causes occasional blackouts and exacerbates energy poverty, all of which limit one’s ability to use air conditioning. Meanwhile, increased energy efficiency of dwellings may decrease their heat stress resistance.
The Performance Requirements of the National Construction Code (NCC) can be met using either a Performance Solution or a Deemed-to-Satisfy (DtS) Solution or a combination of both solutions. The following demonstrates the performance based design process that should be used in conjunction with the Development of Performance Solutions Guidance document.
Numerous mandatory energy efficiency building standards and rating systems have been developed globally. The International Passive House Standard is a voluntary alternative, but there is little data on the performance of houses built to this standard in Australia.
