Tips for a greener, cost-effective future
With South Australia’s hot summers and cool winters, improving your home’s energy efficiency can enhance comfort while lowering energy consumption. Additionally, government incentives and programs are available to support homeowners looking to adopt more sustainable solutions. Some local councils are now also assisting ratepayers in solar panel installations.
Why energy efficiency matters
South Australia experiences extreme seasonal variations, with scorching summer days often exceeding 40°C and chilly winter nights that can occasionally drop to below zero. These conditions can lead to high energy use for cooling and heating. But by improving energy efficiency, households can:
Lower energy costs by reducing reliance on air conditioning and heating.
Increase home comfort with better insulation and temperature regulation.
Reduce carbon footprint by decreasing energy consumption and greenhouse gas emissions. Landlords should note that rental properties with solar energy are very popular with tenants.
Enhance property value by incorporating sustainable features that attract buyers.
Tips for an energy-efficient home
1. Improve insulation and sealing - proper insulation is crucial for keeping heat out in summer and retaining warmth in winter. Consider:
- Roof and ceiling insulation to prevent heat transfer.
- Double-glazed windows or thick curtains to reduce heat loss and gain.
- Sealing gaps around doors and windows to prevent draughts and keep temperatures stable.
2. Upgrade to energy-efficient heating and cooling - heating and cooling account for around 40% of household energy use in South Australia. To reduce costs:
- use ceiling fans to circulate air instead of relying on air conditioning.
- opt for energy-efficient reverse cycle air conditioners with high star ratings.
- set thermostats to efficient temperatures (around 24°C in summer and 18-20°C in winter).
3. Harness solar power - South Australia has some of the highest solar adoption rates in the country, thanks to abundant sunshine and government incentives. To maximise savings:
- Install solar panels to generate electricity and reduce grid reliance.
- Consider adding a solar battery system to store excess energy for later use.
- Take advantage of off-peak electricity tariffs for appliances like dishwashers and washing machines.
4. Choose energy-efficient appliances - appliances can significantly impact energy consumption. When purchasing new appliances, look for:
- High energy star ratings (the more stars, the better the efficiency).
- Induction cooktops instead of gas for energy savings.
- Heat pump hot water systems, which use up to 60% less energy than conventional electric systems.
5. Maximise natural light and ventilation - reduce reliance on artificial lighting and cooling by:
- Installing skylights or large windows to brighten indoor spaces naturally.
- Using light-coloured roofing and external walls to reflect heat.
- Planting deciduous shade trees or installing outdoor awnings to block harsh summer sun.
