Ok, let’s get stuck in. 

In Part 1 of this blog series, we have discussed the unveiling of SA’s NEW 7-star energy rating and how it looks from an industry standpoint, but how will this impact you – the homeowner, buyer or client?

Implementing the new 7-star energy ratings for new homes in South Australia can have both short-term and long-term implications for construction costs. 

Here’s our breakdown of the potential cost impacts:

Upfront Costs

Higher Initial Investment: Building a home with a 7-star energy rating may require the use of advanced materials, improved insulation, high-efficiency heating and cooling systems and other energy-efficient technologies. These elements could contribute to a higher upfront cost for clients.

Design and Planning Expenses: Achieving a 7-star energy rating may involve more detailed design and planning processes to ensure that the home meets the required energy efficiency standards. This may result in additional upfront costs for architects, engineers and other professionals involved in the planning stages, including us, the builder. 

Long Term Savings

Reduced Energy Bills: The primary benefit of a 7-star energy-rated home is the potential for significantly lower energy bills over the lifespan of the property. Homeowners can expect to recoup the initial investment through ongoing savings on heating, cooling, and other energy-related costs.

Increased Property Value: As energy efficiency becomes a more significant factor in homebuyers’ decision-making processes, properties with higher energy ratings may command a premium in the real estate market. This can contribute to increased property values over time.

Government Incentives

Potential Financial Support: Governments often provide incentives and rebates for builders and homeowners who invest in energy-efficient construction. These incentives can help offset some of the additional costs associated with meeting the 7-star energy rating requirements. 

Market Trends and Demand

Competitive Advantage: As sustainability becomes a more significant factor in homebuyers’ preferences, builders who offer 7-star energy-rated homes may gain a competitive advantage in the market. This can lead to increased demand, potentially balancing out initial cost increases.

Industry Adaptation: Over time, as energy-efficient construction practices become more widespread and standardised, the associated costs may decrease as the industry adapts to new norms and technologies.


In navigating this landscape, it’s essential for clients to weigh the upfront costs against the long-term benefits and consider the broader advantages, including potential savings, increased property values, and a positive environmental impact.
