Make sure the ceiling fans you are using are energy-efficient and produces minimum heat when in use.
Place ice or cold water in front of the fan while it’s on. This will cause the fan to circulate the coolness of the ice or water around, thus making your room cooler.
Exhaust fans deserve a special mention given that they are specifically used to remove the excess heat and moisture from your rooms.
All electronic equipment releases heat, including light bulbs. During daytime, try to turn off all of your lights and use the natural daylight that comes into your home.
Light-colored curtains or blinds can help block out sunlight's heat. Windows with insulated glass also help prevent the room temperature from rising.
A considerable amount of sunlight enters your home through the windows, heating the room. Keep your windows shut, blinds drawn and curtains closed in daytime.
To allow in the cold air, open your windows in the evening and early morning. Seek out chances for cross-ventilation, an organic cooling technique
