First the easy ones with family:
Go outside and don’t forget the sunscreen, pools and beaches and great source of fun and coolness. And use a hat when going out, always.
Stay in places with air conditioning, especially those days above 30°C. Community centers, libraries and malls already are using energy to cool the space, so be practical and benefit from that.
Keep cold water in the fridge, ready to drink when needed to “be cool”Now at home:
Hang screens outside the windows
Hanging external blinds outside of your windows during the hottest part of the day could sop up to 80% of the sun’s heat from getting in through the windows.And hey! You can keep them all year long as these shades have the added benefit of providing extra insulation in your home during the winter months too.
Change the colour of the roofAs we all know, dark colours will absorb and retain any heat from the sun. The lighter the colour of your roof, the more heat it will reflect.
Avoid using appliances during the dayMany of the modern appliances we use in our houses everyday generate large amounts of heat. I am talking about computers, televisions, washing machines, dryers, ovens and stoves, dishwashers and more.
Use the barbeque to grill food outside rather than generating heat inside for example, or take advantage of the sun’s energy by drying your clothes outside during the summer.
Plant Some Trees
This is my favorite. If you have enough space around your home, plant some trees or other taller plants away from the walls of your home. The leaves from the trees will provide your house shade in the summer significantly reducing the temperature inside your house.And, please, if you absolutely cannot live without and Air Conditioning Unit, at least invest in one that is energy efficient.
