About this home

Our family home has become the Better Energy Lab itself — a real-life testing ground for energy independence. Through a carefully designed solar and battery system, plus an electric vehicle and plug in hybrid car charged almost entirely from our own solar power, we’ve created a lifestyle where we drive and live on clean, self-generated energy.

This experiment in sustainable living has delivered remarkable results:

  1. Thousands saved every year in electricity and petrol costs
  2. Zero reliance on fossil fuels for daily living
  3. Automated energy management, where solar, battery, EV, and appliances work together
  4. Resilience and backup power for peace of mind.
  5. 4 br all electric home with an electric vehicle and a plug in hybrid. The plug in hybrid has done 3000kms and used about 50L of petrol.

The property has:
- 30kW solar system with 9.7kWh battery - adding 80kWh more
- smart EV charger,
- electric hot water automation making the hot water run from renewable energy.
- efficient variable speed pool pump,
- Bionizer swimming pool water treatment that uses copper and silver to sanitize the pool instead of chlorine, allowing the water to be recycled on the garden.
- solar LED skylights that increase and decrease the light with the intensity of the sun without the potential for leaks or impact on your homes thermal performance as they allow insulation to be installed over the skylight.
Insulation increased to R5 in the ceilings with the original insulation being repaired to fill in the many gaps and a second layer added.
- wall insulation and breathable vapour barrier added to walls as they have been renovated.
- A singular split system AC that has had automation added to switch on based on time and temperature so that the house is precooled with renewables keeping the 4br home cool through summer.
- recycled materials

The house and cars, ran on just 710kWh of grid energy last year with the rest coming from the solar and or battery system.

Q & A

What motivated you to build or retrofit sustainably?
We have always felt that want are part of the environment and what we do matters. Making these basic changes are so easy, they cost very little compared to the value of our homes and they give us so much contentment to know that we are doing our part.
Changing our home to all electric and setting the home and our vehicles up to run from our solar system and battery has been transformative. It's remarkable to think that only 6% of our electricity comes from the grid and that includes running 2 EV's. We don't get electricity bills - we get electricity pay checks as we now supply enough energy to the grid to supply two more homes that use a similar amount of energy as ours.
We have always been up-cyclers, happily giving second hand materials, furniture or clothing a second life. It is incredibly satisfying seeing something that was going to go to landfill becoming part of the fabric of our home, it's nice to think of all of these components (kitchen benches and cupboards, bathroom vanities and shower screens, toilets, light fittings, lamps or even floorboards having their own stories and histories that have all culminated and now become part of our story).
I would love to revamp the garden with natives to bring more life in, build raised vegie patches with water reservoirs underneath, grow avocados and fruits, have chickens and native bees. We will also be painting the roof white to reduce heat gain and the heat island effect, and change the colour of the exterior. We will look to use stone wall features and timber features. We will also be adding a bi-directional DC EV charger as soon as one becomes available for the battery we are installing. This will allow us to charge our cars faster and also take energy out of the cars to support our home or the grid.
