How sustainable design can help homeowners save over the long term

As the cost of living continues to shape the way Australians buy property, sustainable design is becoming a key consideration.

Energy-efficient features are no longer seen as a premium extra, they’re increasingly expected as part of a new home that balances both comfort and long-term cost savings.

Highlighting this demand, realestate.com.au’s New Homes Research 2026 found that 81% of house and land buyers surveyed were interested in homes with energy-efficient features such as solar panels, battery systems and real-time energy monitoring.

“The appeal of energy-efficient smart home features is universal across geographies, life stages and buyer segments,” says REA Group Market Research & Insights Manager Kate Berens. “This points to these features having broad relevance for new home buyers, rather than appealing to a specific niche.”

“Our research also shows strong interest in practical inclusions such as energy-efficient appliances, LED smart lighting and smart thermostats, highlighting the appeal of features that support comfort, efficiency and day-to-day living,” Ms Berens adds.

Cherie McMahon, Stockland Head of Development, Customer and Marketing, says that this is reflected in how buyers are thinking more carefully about how their homes perform day to day.

“Buyers are increasingly looking for homes that are energy efficient, affordable to run and designed to support healthier lifestyles,” Ms McMahon says.

The sustainable features that pay off early

There are a few key elements that buyers are prioritising in their new homes as they look to more sustainable, eco-friendly design.

“Some of the most sought-after features include quality insulation, double glazing, smart home technology, energy-efficient appliances and home designs that maximise natural light and ventilation,” says Ms McMahon.

For many buyers, the benefits of these design choices can be felt almost immediately, primarily through lower day-to-day running costs, with the Climate Council estimating that electrification and energy-efficient upgrades can save households at least $1,119 a year.

In some cases, buyers may also be able to access government rebates or incentives linked to energy-efficient upgrades and all-electric living solutions.

“Sustainable design can deliver real household benefits, from lower energy bills and reduced running costs to greater comfort throughout the year,” says Ms McMahon. “Measures such as electrification, solar readiness and energy-efficient design also help homeowners take greater control of their energy use and future costs.”

Beyond costs, Ms McMahon explains that homeowners also notice how much more comfortable homes can feel when designed with sustainability in mind.

“Homes designed with good insulation, natural light and passive design principles tend to maintain more consistent indoor temperatures throughout the year, making them more enjoyable to live in,” she says.

Future-ready living with lasting value

While the immediate benefits of an energy-efficient home can be appealing, the real value of sustainable design is how it performs over time.

At a neighbourhood level, sustainable masterplanned communities are designed to respond to long-term environmental changes.

Increased tree canopy, water-wise landscaping, greener infrastructure and cooler street design can help reduce urban heat while creating more comfortable neighbourhoods for residents.

“In a masterplanned community, these features work together to create neighbourhoods that are cooler, greener, and more comfortable for residents, while supporting long-term environmental outcomes and everyday liveability,” says Ms McMahon.

When considering further long-term benefits, Ms McMahon also points to growing buyer demand for sustainable homes, with homes in well designed, sustainable communities more likely to retain value over time.

“Homes and communities that already incorporate these features are likely to maintain strong appeal because they align with changing consumer preferences and support a better overall lifestyle,” says Ms McMahon.

“Communities that combine sustainability with connectivity, amenity and liveability are well positioned to remain desirable over the long term.”
