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.
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
When South Eastern Australia was in severe drought at the beginning of the century, a whole array of efforts went into addressing the water shortage. Councils introduced, and then increased, water restrictions. Government handed out low-flow showerheads and shower timers,...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.
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.
Radiant cooling and heating has the potential for improved energy efficiency, demand response, comfort, indoor environmental quality, and architectural design. Many radiant buildings have demonstrated outstanding performance in these regards, and application of the technology in commercial buildings is expanding.
