Research indicates a growing correlation between residential energy features and increased property market values in both the United States and Australia.

In the United States, studies suggest that solar panel installations can increase home values by an average of 4.1% and provide long-term utility cost reductions. In Australia, a report titled ‘The Efficiency Edge’ found that each additional star on the Nationwide House Energy Rating Scheme is associated with an average 1.3% increase in property value. The Australian data also shows that homes with solar panels sold for approximately 2.7% more than comparable properties, while specific sustainable designs in Mount Hawthorn saw premiums between 14% and 24%.
