J Turner Constructions' custom homes

In a huge stride towards a more sustainable future, South Australia has introduced a groundbreaking initiative – the 7-star energy ratings for new homes. This initiative is set to commence in October, 2024.

This bold move aims to not only enhance the energy efficiency of residential properties, but also contribute to the broader goal of reducing carbon footprints and mitigating the impact of climate change.

In this blog post, we will dive into the key aspects of the new 7-star energy ratings and understand how they are reshaping the landscape of new home construction in South Australia.

We have broken down this latest blog post into two parts.

In part two, we will discuss how this could affect you, the client, and how it may impact costs for new home builds in the future for South Australian people.

Understanding the 7-Star Energy Ratings:

The 7-star energy rating system evaluates the energy efficiency of residential buildings on a scale from 1 to 10, with a higher rating indicating superior energy performance.

This comprehensive assessment considers factors such as insulation, orientation, ventilation, and the use of renewable energy sources. Homes that achieve a 7-star rating are deemed to be highly energy-efficient, translating into reduced energy consumption, lower power bills, and a smaller environmental footprint.

Lower Energy Costs:

Homes with a 7-star energy rating are designed to optimise energy use, resulting in lower electricity and gas bills for homeowners. The idea being that the upfront investment in energy-efficient features pays off in the long run, offering substantial savings over the life of the home.

Comfortable Living Spaces:

Improved insulation and thoughtful design contribute to more comfortable living spaces. Homeowners can enjoy consistent temperatures throughout the year, with reduced dependence on heating and cooling systems. This not only enhances comfort but also promotes a healthier indoor environment.

Environmental Management:

Choosing a 7-star energy-rated home aligns with Australia’s commitment to environmental sustainability. Reduced energy consumption means fewer greenhouse gas emissions, making a positive impact on the environment and contributing to South Australia’s broader efforts to combat climate change.

Implications for the Construction Industry:

The implementation of the 7-star energy ratings brings to light the necessity for involvement of architectural design, as well as up to date construction practices. Builders and developers are having to embrace the advanced technologies and materials to meet the stringent energy efficiency criteria, with a clear focus on continuous improvement in the industry. One that, in our opinion, is necessary!

Increased Demand for Green Homes:

With a growing awareness of environmental issues, homebuyers are increasingly seeking energy-efficient properties. The 7-star energy rating serves as a valuable marketing point, driving demand for homes that prioritise sustainability and energy efficiency.


South Australia’s new 7-star energy ratings for new homes mark a significant leap forward in the pursuit of a more sustainable and eco-friendly housing landscape. As homeowners enjoy the benefits of reduced energy costs and enhanced comfort, the construction industry is prompted to adopt innovative practices that prioritise energy efficiency. This initiative will not only transform the way homes are built, but also underscores the importance of individual and collective efforts in building a greener, more resilient future.

In part two of this blog, we will discuss the impacts this will have on your budget, how you can best navigate this change, breaking down what all of this information means for you – and your wallet!
