Residential Projects That Achieve Strong Star Ratings

What a High Star Rating Really Means

When a home achieves a strong NatHERS star rating, it’s doing more than ticking a compliance box. It’s proof that the building has been designed to stay naturally comfortable year-round, using less energy to heat and cool.

Star ratings measure thermal performance. The higher the rating, the better the home’s ability to maintain stable indoor temperatures with minimal energy use. In other words, it’s a clear indicator of efficiency, comfort, and cost savings for the homeowner.

Why It Matters for Residential Projects

In residential design, performance is everything. A home that performs well feels comfortable through every season and costs less to run. For architects and builders, achieving strong ratings early also reduces the risk of redesigns later in the approval process.

At Studio Terra, we use accredited NatHERS software like HERO and BERS Pro to model how a home responds to Australia’s climate. This gives our clients clear, data-backed guidance on how to lift performance without compromising design intent.

Simple Design Tips to Improve Your Star Rating

Small design decisions can have a big impact on a home’s energy efficiency. Here are a few practical ways to boost your NatHERS rating:

1. Get orientation right

Position living areas north to capture winter sun and reduce heat gain in summer. The right orientation sets the foundation for a naturally comfortable home.

2. Insulate effectively

Walls, ceilings, and floors all play a role in retaining warmth during winter and keeping heat out during summer. Quality insulation improves comfort and reduces energy bills.

3. Choose high-performance glazing

Windows can make or break a rating. Double glazing or low-e glass helps maintain thermal balance, especially in climates with temperature extremes.

4. Seal air leaks

Even a small gap around doors or windows can let conditioned air escape. Airtight construction prevents heat loss and reduces the load on mechanical systems.

5. Plan shading early

Incorporate eaves, pergolas, or vegetation to block harsh summer sun while still allowing winter warmth in. Good shading design is a natural, low-cost way to improve performance.

The Power of Early Assessment

The best results come when energy efficiency is considered from the start. By engaging an ESD consultant early, you can identify potential issues before they affect compliance or cost. Early intervention allows your team to refine layouts, select materials strategically, and ensure your project meets BASIX, NatHERS, and Whole of Home requirements without delays.
