We hope homeowners ​​​​can use Green Specs to help improve the sustainable performance of their home by undertaking major renovations or small improvements.

There’s a variety of changes that can be made to your:

  • Kitchen

  • Laundry
  • Bedroom
  • Garage
  • Outdoor spaces
  • Garden

These changes can help make your home more energy efficient, healthy, and resilient.

You can filter the plan to show:

  • Positive changes – ways to make your home more energy efficient
  • Healthy changes – ways to reduce harmful emissions in your home
  • Resilient changes – ways to help safeguard your home against the effects of climate change
  • Specific price ranges – if you’re on a budget

It’s super simple to use.


As we all consider new and progressive ways to reduce our impact on the environment, most Australians are aware that we should all be making more sustainable choices when it comes to home renovations.

New research from Allianz has revealed that while a quarter of Australian homeowners with a renovation plan aren’t even considering making their home greener (24%), close to half of Australian homeowners would like to renovate their home to make it more sustainable (46%) but admit they’re unaware of where to start (46%).

This is where Green Specs comes in.



The research was conducted by YouGov via an online survey conducted between 29th May to 5th June 2023. The sample comprised of 1,043 Australian homeowners and investors aged 18+ including 739 homeowners and 304 investors. Homeowners were defined as Australians aged 18+ who own the home that they are living in only (outright or with a mortgage) and don’t own any other property in Australia. Investors were defined as Australians aged 18+ who own at least an investment property (outright or with a mortgage) which they are not living in. The data is weighted by age, gender and region to reflect the latest ABS population estimates.

Key impact categories



If you’d like to make a real difference with your sustainable improvements, making sure your home is warm enough in winter is a good place to start. Heating our homes takes up the most energy, followed closely by cooling. The next highest consumer of energy is water heating, followed by appliances, lighting, cooking, and standby power.

We can spend 90% of our time indoors and most of that time at home, so making sure our homes are healthy is critical to our wellbeing. You might be surprised to know indoor levels of air pollutants may be 2 to 5 times higher than outdoor air. Things like high use of air conditioning, poor ventilation, and issues like mould are the key culprits creating an unhealthy home environment.

Extreme weather and climate change can have an impact on our homes. The good news is we have the ability to prepare and be ready. A resilient home is one that is robust, and in some cases goes beyond the minimum building standard requirements. A robust resilient home may help reduce the risks from extreme weather events and climate change conditions like bushfires, flooding, and heat.
