Starting 1 May 2025, Western Australia will adopt the new National Construction Code (NCC 2022) energy efficiency rules. That means all new homes will need to meet a minimum 7-star energy rating under the NatHERS (Nationwide House Energy Rating Scheme).
This is a big step forward. It’s great for the environment, great for your energy bills—and it changes how homes are designed and built across WA.
But what does this mean for you?
It Means You’ll Need a Smarter, More Efficient Home
The new rules aren’t just about ticking boxes. They’re about building homes that stay cooler in summer, warmer in winter, and use less energy all year round. They’re also about managing things like condensation and airflow more carefully to improve comfort and prevent damage over time.
It’s a step toward future-proof living.
Why Norde Homes Is Already Ahead of the Curve
At Norde Homes, we’ve been designing and building energy-efficient homes in Perth long before these new rules came into play. In fact, many of our homes achieve NatHERS ratings of between 8 and up to 10 stars—well above the minimum 7-star requirement.
Here’s how we do it:
• Passive solar design – our homes are designed to make the most of natural light and heat.
• High-performance insulation and double glazing – keeps the temperature steady and the bills low.
• Smart layout and orientation – every room is positioned for maximum comfort and efficiency.
• And many other, top-secret methods and approaches that we will not divulge here!
Building a home is a big step—choose a builder who understands passive solar design. Norde Homes creates stunning, custom homes that maximise natural light, comfort, and energy efficiency. Let’s bring your vision to life—book a free consultation today.

The new NCC 2022 changes may feel like a challenge to many builders. But for us, it’s business as usual. We’ve spent years perfecting the design and construction of homes that go beyond compliance.
We know what works. We know what to look out for. And we know how to build homes that are comfortable, sustainable, and ready for the future.

If you’re thinking of building a new home in WA, now’s the perfect time to talk to a builder who’s already leading the way.
