Simple tips for cooling a room without using air conditioning.

Why no air conditioning? There are several reasons: not everyone has this option at home, purchasing and using it can be very expensive, but above all, for ecological reasons! Since artificial air conditioners use a lot of energy, it's interesting in hot weather to look for alternative techniques that, combined, can effectively lower the temperature in your home and be more environmentally responsible. Here are some of them:

1. Reduce your use of electrical appliances.

Ovens, stoves, computers, washing machines, dryers, etc., are all appliances that generate heat during operation and even in standby mode. In summer, prioritize cooling to avoid raising kitchen temperatures, start appliances at night when you can ventilate the room with fresh outside air, let clothes dry naturally if possible, and remember to completely switch off unused appliances (TVs, PCs, game consoles, etc.). Hunt down old light bulbs and replace them with less-heating LED models.

2. Prioritize lightweight fabrics.

Whether it's bed linens, curtains, or sofa covers, switch to summer mode with breathable materials like linen or cotton to allow air circulation. Prefer light colors that reduce sun absorption. This advice applies to your paint and wall coverings as well.

3. Focus on potted plants.

Besides decorating your home, plants can also help lower indoor temperatures during hot weather. How? Through the process of water evaporation. When they "sweat," they release stored water to cool the room... and cool you down at the same time! Another reason to decorate your room with aloe vera, fig, or Boston fern is that they are especially effective at creating this desired effect.

4. Create a draft.

In cooling a room, opening windows is a crucial and obvious reflection of the importance of this. This should be done at night, unless it's late and/or early in the morning when outside temperatures are lower. Hang damp sheets in front of them and open windows on each side of the house to allow air to circulate instead of becoming stagnant.

5. Use the fan efficiently.

Fans are a simple and economical solution, but do you know how to use them effectively? For best results, consider placing them in front of an open window or doorway where fresh air comes in. The fan will then draw in and push out warmer air from the room, making way for warmer air. You can also place a bowl of ice in front of the fan or a damp cloth regularly to cool the air it blows. If you have a ceiling fan, rotate it counterclockwise to push air downwards and create a cooler breeze.

6. Increase the humidity in the room.

Using a misting fan or humidifier that evaporates fine water droplets can help to pleasantly cool the air in the room.

7. Close your doors and windows wisely.

Again, it seems sensible to close the shutters during the hottest part of the day, but what do you do when you're away from home and you can't leave the shutters closed from morning till night? Or do you simply not feel like the fun of snapping the shutters shut 15 times a day? We have the solution: automatic sunshades.

And what about energy improvements?

Although this solution is less simple at first glance, it's not just about laying down sheets or pressing "walk," but it still provides long-term peace of mind. In fact, with better thermal insulation of your home, it automatically brings comfort. Installing exterior sun protection is not the only task; it also involves more significant work on the walls, floors, roof, or even connecting to the district's thermal network (if available nearby). And if the budget can sometimes be substantial, you should know that there is state assistance from MaPrimeRénov to alleviate the financial burden.

Keep your home cool and comfortable without air conditioning with automatic sun blinds.
 

Instead of using solutions to cool your room down, why not keep it cool at all times, even during a heatwave?

With motorized and connected sun blinds, you not only stop or limit the radiator effect of your windows—which absorbs sunlight by default—but you can also do it without any intervention. Simply automate the process so they always adjust to the optimal position at the right time, even when you're not home. This way, you're guaranteed a warm and comfortable home without worry.

We're talking about indoor temperatures increasing by 4 to 7°C* during peak heat periods! You can reduce your use of artificial air conditioning by up to 70%** while simultaneously lowering your carbon footprint.
