Stay Cool, Save Energy and Money, and Protect the Planet
Keeping your home cool during the hot weather doesn’t have to come at a high cost to your wallet or the environment. By making small changes to how you use your air conditioning, you can stay cool, reduce carbon emissions, save money, and contribute to a healthier planet.

Over the course of a summer, these savings add up—imagine the impact we could have if everyone made this change!
While it may seem like setting the thermostat lower would cool the room faster, air conditioners remove heat from the air at a constant rate. The thermostat setting only determines the final temperature, not the speed of cooling.
To enhance the cooling process, focus on actions like closing doors and windows, using fans to circulate air, and closing the curtains to shade windows from direct sunlight.
By setting the thermostat to a comfortable 24°C, you’ll cool your home just as efficiently while using less energy and reducing strain on your Air conditioning system. At 24°C, the air feels comfortably cool without being overly cold, and is also gentler on your body and less likely to dry out your skin or sinuses.
Small changes at home can lead to big results for the planet. Be the change—use less energy, save money, and help build a net zero and smarter, cleaner, greener future. A degree really does matter!
