How to make your home energy efficient

An energy efficient home is not only good for the planet, it can also lower your bills and save you money.

Benefits of an energy efficient home

Making your home more energy efficient can:  

  • save you money on your energy bills
  • lower your carbon footprint
  • help create a comfortable indoor living environment

Ways to make your home more energy efficient

There are many ways you can save energy – from keeping your thermostat set at 24°C, or higher, to washing your clothes at a lower temperature. But as well as changing your habits, you can also make changes to your home to make it more energy efficient. 

Switch to energy efficient products

From water heaters to washing machines, more and more household products and appliances are becoming energy efficient. 

Using such products can be a great way to save money on your energy bills. For example, if your air conditioning unit is over 10 years old, consider replacing it with a new energy-efficient one, with a high ESMA rating (4 or 5 stars). This will help you save up to 25% of cooling consumption.1


LED lights are also 85% more energy efficient than traditional bulbs. Each LED lamp you use instead, can save you money over its lifetime.

Cooling and irrigation

You can reduce cooling consumption by:

  • applying weather stripping and sealant around all doors and windows to keep the cooled air in, and hot air out
  • hang curtains, drapes, shades and awnings over windows to reduce heat

You can save water by:

  • maintaining sprinklers and checking for any leaks
  • installing a rain shutoff device on automatic sprinklers
  • adjusting sprinklers, so they water the lawn (not the pavement) to avoid waste
  • planting native plants in your garden, which need minimal or no irrigation

Generate your own renewable energy

Solar energy is a form of renewable energy – it produces no emissions and reduces our reliance on fossil fuels. By installing solar panels, you can use sunlight to generate your own electricity or provide hot water. 

Personal savings

If you have cash available, using your savings can be a good option to fund home improvements, especially smaller projects such as draft-proofing. You can also avoid paying possible interest that may come with borrowing. However, it's important to consider whether there are any charges for withdrawing your savings and whether you'll have enough money left over for an emergency fund.
