Keeping our home at a comfortable temperature during the hottest months of the year doesn’t have to be synonymous with skyrocketing electricity bills. With good energy habits, you can enjoy a cool home, reduce consumption, and save without even noticing.
Below, we detail three practical and immediately applicable tips that will help you optimize the thermal comfort of your house this summer using the physics of building and your daily habits wisely.
1. Cross-ventilation in cool hours and lowered blinds
Outdoor air can be your great ally if you know when to let it in. During the day, when outdoor temperatures exceed 30°C, keep the blinds down and the windows closed in areas that receive direct sunlight. This creates a barrier effect against heat radiation.
At nightfall or early in the morning, when the outdoor temperature drops, open windows at opposite ends of the home to generate cross-ventilation currents. The fresh air will sweep away the heat accumulated in the walls and ceilings during the day.
2. Modify your kitchen habits to avoid generating additional heat
The oven and kitchen stoves are major heat sources that quickly warm the air throughout the house. During extremely hot days, try to cook early in the morning, plan cold menus (salads, cold soups), or use alternative, faster and more efficient appliances like the microwave, which heats the food directly without dissipating massive heat into the room.
3. Leverage the combination of air conditioning and fans
A ceiling fan consumes up to ten times less energy than a conventional air conditioning unit. Although the fan does not directly cool the air, it creates a current over the skin that reduces the wind chill by about 3°C or 4°C through sweat evaporation.
Combine both systems: turn on the AC at a moderate temperature (like 26°C or 27°C) and combine it with a fan to distribute the cold air throughout the room. In this way, you will achieve the same feeling of comfort as if you programmed the AC at 23°C, but with energy savings of up to 30%.
