Prepare your home for summer

September 2011

The mercury is rising, but your energy bill doesn’t have to if you prepare your home for the warmer months.

Ausgrid’s energy efficiency expert Paul Myors said there are simple steps you can take to stay cool without burning a hole in your pocket.

A four person household can cut up to 10% off their electricity bill and up to one tonne of CO2 from household emissions, by planning ahead and using appliances efficiently.

Ceiling insulation can reduce indoor temperatures by as much as 10 degrees in summer and cut your cooling costs by up to 30%.

However, keeping the heat off your house in the first place is even better.

Start by shading windows with external blinds, pergolas, or even trees and plants. Each square metre of direct sun on or through windows can be like running a one bar radiator in your home.

Leave doors and windows on opposite sides of your home open to take advantage of natural breezes and make the most of cross ventilation.

On milder summer days consider opting for a fan over the air conditioner. By circulating air around the room, fans can make it feel around three degrees cooler, and they cost as little as $5 a year to run.

It’s also wise to buy a thermometer to know exactly how warm it is inside. With a cool breeze flowing through your home you should be comfortable in low 20 degree Celsius temperatures.

If you need to use the air conditioner, try to avoid overcooling below 23 degrees Celsius. Each extra degree lower can add up to 10% to running costs.
