About this home

This project home, built in the 1970s, was typical of the era with no wall insulation and minimal in the roof. However we did rotate the design so the living areas faced north, and with abundant north glazing and an outdoor living area shaded by a deciduous vine, plus no west facing glass the house was ok. In the 1990s improvements were started, solar hot water, a pale roof repaint and plastic film ‘double glazing’ applied to some south facing windows.

The next decade saw PV panels on the roof, blow in insulation installed in walls and roof, rainwater storage and circulation and an air-cond for heating. The 2010s included double glazing the extensive north facing glass, increasing PV to 4KW, painting the dark brick a pale heat reflecting colour. In this decade we have added an EV and upgraded power to 10KW PV and a storage battery. Electric mower, BBQ and bikes continue the story. An EV now sits in the carport.

Q & A

What motivated you to build or retrofit sustainably?
My concerns about climate were well front of mind in the 1990s, that was the main motivator. Taking action was very important for me and my family. Comfort later turned out to ba a great bonus.
The installation of the first PV panels in 2006 was a big turning point. It was a major expense, with no expectation of a profitable return but great satisfaction of trying to live with minimal imported energy.
When I discovered how little insulation the house had - none in the walls and minimal in the roof - after access was blocked with PV panels. If only the house had been properly insulated when built.
We drive an EV most of the time, I wish we had an EV capable of towing our camper trailer and that there were sufficient EV charging stations in more remote areas to make touring by EV more realistic.
