Get More from ’74

Our house was built in 1974 and is a standard single-story brick veneer with 4 bedrooms. It has been our home since 1998. We are now a family of 3, and have been learning about and taking action on ‘sustainability’ since 2006. Our approach is: ‘be the change you wish to see’. Over the last 19 years we have progressively taken many (little, big, low-tech & DIY!) actions to reduce our direct usage of fossil fuels, mains water and try to limit our overall ecological impact.

DOWN WITH FOSSIL FUELS:
We have:

• Replaced roof with added R3.1 insulation and insulated ceiling with Earthwool R3.5
• Installed angled shade sail
• Sealed all internal vents
• Installed solar panels then upgraded system to include battery
• Retrofitted secondary glazing on windows
• Installed solar hot water then replaced with heat pump
• Invested in 3 Electric Vehicles (including a legal challenge and win at the High Court!)
• Installed solar ventilation
• Changed all light-bulbs
• Seasonally use Renshade and other DIY blinds
• Use cross-ventilation and passive heating/cooling
• Made DIY window pelmets

as well as consciously minimised our energy consumption.

RESULTS:
Electricity usage per day = 5-12kWh (depending on season and EV charging) – compared to benchmark of 18kWh in our suburb.
Gas (winter peak) usage per day = 194MJ – compared to benchmark of 340MJ per day.
Gas (summer) usage per day = 31MJ – compared to benchmark of 58MJ per day.

DOWN WITH MAINS WATER:
We have: installed 5 rainwater collection tanks and plumbed to toilet and washing machine, re-used grey and tap water within the home & garden, used mulch on garden beds, as well as consciously minimised our water consumption.

RESULTS:
Mains water usage per day = 100-220 litres (depending on season) – compared to benchmark of 500 litres in summer and 395 litres in winter, and Target 155.

DOWN WITH OVERALL ECOLOGICAL IMPACT:
We have: grown our own (limited range of) vegetables, DIY worm-farm, composted all organic matter, enjoyed back-yard chickens (sadly no longer with us), re-used and recycled things, generally tried to ‘consume with a conscience’, eaten less meat, shifted money to ethical funds, and as a family love going on regular ‘Op-Shop Crawls’!

Our story can show it is possible to “Get More from ’74” – even when the house is old, has numerous design faults, and is poorly oriented on the site. We would like to share what we have learned, and inspire others.
