About this home

In the last few years this building has undergone a significant change, from all gas and fairly inefficient, to all electric and fairly efficient.
As we are passionate about home efficiency and sustainability, we could see the potential in this home from the beginning and knew that conversion to electric would be fairly straight forward.
Our first step was to install a lot of solar. Then halogen downlights were replaced with LEDs, blow in wall and underfloor insulation was added, gas ducted heating was swapped for reverse cycle and the evaporative cooler was removed. The hot water was converted to a heat pump, and the cooktop to induction. All this was done in just a few days and the benefits were immediately noticeable.
The home is an ongoing experiment, with a range of approaches to draught proofing and other efficiency measures being trialed.

Q & A

What motivated you to build or retrofit sustainably?
The principal concern was to eliminate the use of gas, but we deterimined that it would make sense to ensure that in replacing gas we also aimed to end up with a more efficient house.
I found replacing the ducted gas heater and evaporative cooler with one solution - ducted reverse cycle AC to be the biggest difference to my comfort and enjoyment of the home. However there is no doubt that the extra insulation and air tightness measures are what made a difference to the bills.
We were pretty confident we knew what we were getting into, but the cost to get two small cuts made in an artificial stone benchtop (given the new regulations around silicosis) was a surprise. We also probably would have benefited from understanding the limitations of the power supply to our garage earlier on. The garage is supplied by a 32A line under the driveway, so we are limited to 7kW for all activities going on in the garage, meaning we must adjust our car charging if using a lot of power in the garage.
It would be lovely, and probably an excellent fire protection measure, to add a pool to the north of the house that can be accessed from the deck.
