Navigating the 7-Star Transition in WA

Date: April 2026

Category: Industry Updates

The landscape of Western Australian residential design has fundamentally changed. With the move to 7-star NatHERS minimums and the introduction of Whole-of-Home energy budgets, the “compliance check” of the past is no longer sufficient.

Design as the Primary Tool Reaching 7 stars isn’t about adding more “gadgets” to a building; it’s about returning to the fundamentals of bioclimatic design. By focusing on the Thermal Envelope—the relationship between orientation, shading, and mass—we can achieve these higher standards while maintaining, or even reducing, construction costs.

The Whole-of-Home Reality We are now looking at the home as a complete system. This includes:

• The Shell: High-performance glazing and strategic insulation.
• The Systems: Energy-efficient heating, cooling, and water systems.
• The Offset: Utilizing solar PV to balance the energy budget.

Whether you are an Architect protecting a design vision or an owner-builder looking to future-proof your investment, our goal is to provide the technical modelling that makes 7-star performance a natural outcome of good design.
