As the clock ticks down to May 1, 2025, Western Australia (WA) is on the brink of a significant shift in home construction.
New homes and apartments will be required to meet minimum 7-star energy efficiency standards under the Nationwide House Energy Rating Scheme (NatHERS), promising healthier living spaces and reduced power bills for homeowners.
The transition to 7-star ratings demands a blend of innovative design and high-performance materials.
WA’s building industry, particularly the glass processing and window fabrication sector, has been preparing for this change over the past two years.
Clinton Skeoch, Executive Director & CEO of the Australian Glass and Window Association (AGWA), emphasised the crucial role of windows in achieving higher energy ratings.
“Windows account for around 40 per cent of heat loss and 87 per cent of heat gain in Australian homes, so glazing is a key factor when it comes to achieving higher energy ratings,” Skeoch stated.
The benefits of these upgrades extend beyond energy savings.
Skeoch noted: “Better performing windows significantly enhance the comfort and health of residents while reducing energy consumption, and that makes a big difference to household running costs.”
Contrary to concerns about potential high costs, a comprehensive study commissioned by AGWA in 2024 revealed encouraging news.
The average cost to upgrade a new three to four-bedroom home from 6-star to 7-star energy efficiency was estimated at approximately $4,260, significantly lower than previous industry forecasts.
Skeoch highlighted the long-term benefits of this investment, stating: “When you factor in annual energy bill savings of hundreds of dollars, the payback on investment period for new home buyers will occur within the first few years of ownership.”
As May 1 approaches, WA’s world-class glass and window sector stands ready to meet the growing demand for higher-performing windows, having invested heavily in new plant and equipment.
This transition marks a significant step towards sustainable housing in Western Australia, promising not only environmental benefits but also long-term cost savings for homeowners.
