Energy advice: how to be more energy efficient
Did you know that if you can naturally increase the temperature of a room by just 1 degree C, you could save up to 10% of operating costs? Or that worldwide, it’s estimated that buildings account for approximately 40% of greenhouse gas emissions, yet between 20 to 50% of energy used in buildings is simply wasted through inefficiencies such as poor insulation or excess lighting?
Ever wondered how much more electricity you and your family could save, simply by making a few small changes to the way you live? Want some environmental tips on how you could be more energy efficient?
Here are a few simple energy efficiency tips which can help you be smarter about energy use, so as to take the heat off your next bill:
- Secure your home. Repair faulty door seals, hang curtains or blinds so they fit close to window frames and lay rugs securely on bare floors.
- Dress for the weather. “Layer up” in winter and wear cool, natural, breathable fibres in summer.
- Keep the air where it’s needed. Keep doors closed to unused areas (unless your heating or cooling system requires doors or windows to be opened).
- Stay consistent. Try not to change the thermostat settings often. Manufacturers recommend settings of 24°C in summer and 20°C in winter.
- Use curtains. Close curtains over large glass areas (you can lose up to 16% of heat transfer trough glass)
- Maintain your appliances. Check them regularly to remove dust and ensure adequate air flow.
- Use fans rather than air-conditioning. Fans use minimal energy, operate at a fraction of the running cost of air conditioners and can reduce the number of days you use air conditioning.
- Adjust your air-conditioning settings. For maximum efficiency, set the air conditioning unit to re-circulate cool air instead of pulling warmer air in from outside.
- Correctly position your air-conditioning unit. Make sure the outdoor section of your air conditioning unit isn’t installed facing the sun (north or west), unless the area will be constantly shaded to allow adequate cooling of the unit.
- Set rules. For example – only use your air-conditioner on days when maximum temperatures are 30 degrees C or higher (instead of 28°C or higher) – and you could save between 2 and 10% of your energy use.
