When you're shopping for appliances, heating, cooling or lighting products, you're not just buying for today — you're investing in the long-term performance and efficiency of your home. That’s where energy labelling systems like MEPS and LCA labels come in.

A cold water diverter is a mechanical valve installed on a hot water line. It redirects the initial cold water, known as redwater, that sits in the pipe before hot water arrives. Instead of wasting this water down the drain, the diverter sends it to a greywater tank, a garden irrigation system, or back into the hot water storage system for reuse. These diverters work using water pressure and do not require electricity.

Windows are one of the main reasons a home loses heat in winter and gains heat in summer. Selecting high performance windows is critical to achieving modern energy efficiency standards and reducing ongoing energy bills.

When selecting windows for a new build or renovation, it is essential to consider Australia’s varied climate zones and the latest energy efficiency requirements. The National Construction Code (NCC) now mandates a minimum 7‑star NatHERS rating for all new residential projects.

The Window Energy Rating Scheme (WERS) enables windows and glazed doors to be rated and labelled according to their annual energy impact on a house in any Australian climate. WERS is managed by the Australian Glass and Window Association and complies with the protocols of the Australian Fenestration Rating Council.

Windows are often one of the greatest contributors to energy loss in Australian homes. Choosing the right energy-efficient window solution can reduce heating and cooling demand, improve indoor comfort and help meet modern energy standards.

If you're renovating or building and want to improve your home's energy efficiency, Low-E glass is worth considering. Short for low-emissivity glass, this high-performance glazing helps regulate indoor temperatures, reduces energy bills and boosts comfort—all without sacrificing natural light.
