The National Construction Code 2022 requires all new Australian homes to meet a minimum energy rating of 7 stars under the Nationwide House Energy Rating Scheme (NatHERS), an increase from the previous minimum 6-star rating. Due to these stricter requirements, architects and designers need to place greater focus on higher performing window systems. There is a common misconception that designers will need to reduce the number of windows or opt for smaller windows in new builds. However, it is possible to increase the thermal efficiency of windows, without compromising on aesthetics or functionality, with solutions currently available on the market.

Designing for 7 stars: Key window design considerations under the new energy efficiency building standards examines the impact of the new minimum 7-star energy rating on window design. In this whitepaper, we discuss several design strategies that will improve the thermal efficiency of windows, including choosing the right framing materials, preventing air leakage, double and triple glazing units, and low-E glass options. With governments constantly looking for ways to secure an energy-efficient future, this information is essential for practitioners operating under the new standards and beyond.

Established in 2009, BINQ is a privately owned Australian company whose influence comes from traveling the globe researching the most advanced window systems from Europe. BINQ’s windows are some of the highest performing windows in the world, with a range including timber, alu-clad and uPVC windows in a variety of styles and design options.
