Energy Efficiency Ratings QueenslandDid you know that the minimum energy efficiency rating for new houses and townhouses in Queensland is 6 stars. This also applies to additions, alterations to your existing home. What does that mean and how can it be achieved?

When we speak about energy efficiency, we refer to the idea of using less energy while providing the same outcomes. Houses that are more energy efficient reduce the need for other means of cooling homes in the hot Queensland weather – such as air conditioners and fans. This in turn reduces our reliance on electricity outputs while also benefitting the environment by lowering greenhouse gas emissions in the state.

The star rating (out of 10) applies to the shell of the building – i.e the roof, walls, windows and flooring – all of which play a vital role in the overall comfort and energy efficiency of the house. The rating does not include air conditioners, hot water systems, lighting, fans, fridges or any other fixed appliances that are found in the home.

The code does not apply to industrial, public or commercial buildings.

The benefits of a 6-star house
