Why 7-Star Energy Efficiency Is a Smart Move in WA
When it comes to building a new home, energy efficiency is no longer a nice-to-have — it’s a must. And if you’re building in Western Australia, aiming for a 7-star energy efficiency rating isn’t just a box to tick — it’s a smart, future-focused choice that can save you money, boost comfort, and reduce your environmental impact.
Let’s break it down.
What Is a 7-Star Home?
In Australia, homes are rated on a scale of 0 to 10 under the Nationwide House Energy Rating Scheme (NatHERS). The higher the rating, the more energy-efficient your home is. A 7-star home is designed to naturally regulate its temperature, which means you’ll rely far less on artificial heating and cooling — while still staying comfortable year-round.
Why It Matters (Especially in WA)
Western Australia is a land of extremes — scorching summers, chilly winter nights, and rising energy costs. In this environment, smart design does more than look good. It works hard to keep your home liveable and affordable.
Here’s why going for 7 stars makes sense:
* Lower Energy Bills – a 7-star home can use up to 30% less energy than a 5-star home. That translates to real savings on your electricity bills every single year — without sacrificing lifestyle or comfort.
* Year-Round Comfort – energy-efficient homes are designed with your lifestyle (and climate) in mind. Quality insulation, strategic shading, and cross-ventilation all work together to keep your space cool in summer and warm in winter — without constantly reaching for the remote.
* Better for the Planet – reducing your home’s energy use means lowering your greenhouse gas emissions. With much of WA’s power grid still running on fossil fuels, energy efficiency plays a key role in creating a more sustainable future — one home at a time.
A Future-Ready Investment
As energy standards rise and buyers become more eco-conscious, homes with higher energy ratings are increasingly in demand. A 7-star rating adds long-term value to your property while making it more appealing to the next generation of homeowners.
How to Achieve a 7-Star Rating
You don’t need to compromise on design to build smarter. Here are some of the key features that help homes reach 7 stars:
* Insulation – quality wall and ceiling insulation that works to keep heat in during winter and out during summer.
* Windows & Glazing – double glazing, Low E glass, and thoughtful shading make a huge difference to how your home performs.
* Orientation – designing your home to maximise winter sun and block harsh summer rays helps regulate temperature naturally.
* Smart Systems – choosing energy-efficient lighting, heating, and cooling appliances ensures every element is working with — not against — your design.
