40 per cent of the world’s energy resources are used in buildings, both residential and commercial. Here are some no-cost or low-cost ways to reduce energy use and improve the comfort of your home or office.
- Heating and cooling systems use 40 per cent of the average home’s total energy. If you are installing or upgrading a system, star rating labels will help you choose the most energy-efficient and cost-saving option. An evaporative cooling system is one of the most economical and efficient in our climate.
- External shading of the home, and windows in particular, can be up to five times more effective than internal shading (i.e. curtains and blinds) in blocking summer heat. Examples of effective external shading include shutters, window awnings, landscaping, and roof eaves. If you are installing shading, make sure it will allow winter sun in, to help you reduce heating bills.
- If you can’t make external modifications, installing thick drapery (i.e. curtains) and closing them to block summer sun will make a difference, these can also help to keep heat inside during winter.
- Filling in gaps and blocking drafts around older homes (under doors and around windows) is a cheap and easy way to improve comfort and efficiency, particularly during winter.
- Use energy efficient LED lighting and controls such as sensors to minimise electricity use
- When looking for an electrical appliance check the Energy rating - appliances | energy.gov.au Different appliances can be compared Home | Energy Rating
