Summer Energy-Saving Tips

It might be hot and sunny outside, but we’ve got some useful tips and suggestions to keep you cool during the summer, and make your home more energy efficient.

Thermometer

Fan

Blinds

Tree

Timer

Set your A/C for 25°C when at home and 28°C or switch it off completely when out to reduce cooling costs. Make sure ceiling fans run in a counter-clockwise direction. This helps circulate a cool breeze in your home.Close your blinds and curtains during the day. This will block warm sunlight and help naturally cool your home.Plant a tree or shrub to give shade to your central A/C. This can improve the unit's efficiency by up to 10%.Consider timers or motion sensors for lights. Adjust timers to account for more daylight hours in spring/summer.

Plug

Sliding door

LED lightbulb

Tap

Dish washer

Unplug electronics not in use so they don't consume "phantom power" or small amounts of electricity.Keep the track on your sliding door clean. A dirty track can damage the door's seal and let cold air escape.When purchasing a light bulb for your home, consider investing in LEDs. They are efficient as compact fluorescents (CFLs) but last about 3X as long.Try to quickly repair leaky faucets. One constant drip can waste up to 182 litre-sized bottles of water a week.Use the air dry option on your dishwasher or just stop your machine before drying cycle starts and open the door.

Leaf

Fridge

Clothes line

Freezer

Shower

If shopping for a new appliance, consider an ENERGY STAR other higher efficiency model for a high standard of energy efficiencyAvoid overfilling your fridge, which decreases air circulation and makes it work harder and less efficiently.In the summer, consider using a clothesline to let the sun and breeze dry your clothes.Don't let freezers build up more than 6 mm of frost. Defrost regularly to keep freezers working their best. Opt for a shower rather than a bath: a 5-minute shower uses about half as much water.

Pool

AC Filter

Bbq

Roof vent

AC

A single-speed pool pump uses up to 10 times more power in a season than a typical new fridge uses in a year. Consider installing a variable speed pool pump that uses less energy.Dirty A/C filters restrict airflow and can cause the system to run longer, increasing energy use. Replace  or clean filters monthly for maximum benefit.Avoid heating your home by using appliances in the summer – think about using the BBQ and the clothes line more oftenConsider attic ventilation to improve your home’s comfort. Energy costs rise if your A/C is fighting a hot atticTry to install your A/C in a shaded area. In direct sunlight it will consume up to 10% more energy than it will if shaded.Your thermostat should be shaded as well.

Door

Fireplace

LED and CFL lightbulbs

Open window

Microwave

Close as many doors leading to your air-conditioned space as possible to keep cool air inClose off fireplaces to prevent cool air from escaping up the chimneyIn areas where lights are left on for long periods, replace incandescent bulbs with cooler-operating CFLs or LEDsUse natural or fan-assisted ventilation to cool your house whenever outdoor temperatures and humidity levels drop but make sure your thermostat is switched off.Microwaves use up to 50% less electricity when used in “low” heat function than an electric stove. Use your microwave to reheat or defrost food quickly
