How to naturally refresh your home?
A consequence of global warming, we are facing an increase in the number of hot days. In addition, these periods of high heat are more and more frequent.
The most common solution is to install air conditioning. Unfortunately, this solution is very energy intensive. This accelerates the rise in temperatures.
On the other hand, this solution is not always technically or legally possible (urban planning law, historic building, location for the block, etc.
In order to offer alternatives to air conditioning, in the spirit Lacentrale-eco.com, we have studied what are the possibilities to refresh a home while limiting its environmental impact.
Let's discover together the simple solutions to keep your interior as fresh as possible:
- What to do in case of heat wave?
- What are the s to be adopted ?
- How to protect yourself from the heat and lower the indoor temperature of your home?
- What are the alternative to air conditioning?
West gestures to lower the temperature
Close your shutters, blinds and curtains during the day
Commit close all your closures in the morning around 8am/strong><, as soon as the temperature starts to rise. This basic advice, allows to preserve the freshness of a few precious degrees.
Even simple blackout curtains constitute a first barrier.
On the other hand, you should aerate after 9pm during the hottest periods (or as soon as the outside temperature is lower than that of your home).
Green plants are your allies
A plant is pretty but not only. The leaves create , if you can, put some on your balcony or terrace. They play the natural.
In the interior, they clean the air. Don't wait for high temperatures to plant, it's too late.
In the house, the best is to put climbing plants on the walls most exposed to the sun. They will absorb some of the heat and make the situation more pleasant.
During the heat wave of 2003, it was measured a gap of 8 to 10 ° between the center of Paris, very mineral and the outside of the city, more wooded.
Plug all unused electrical appliances
The box, the pc, the screens, all these electrical appliances produce heat. Simply unplugging them makes you do it while avoiding creating extra calories.
Bref, a good gesture for you, your wallet and the planet.
Limit the use of the oven, cooking systems, iron
Another gesture to fight against the heat is to adapt your kitchen to avoid the use of your oven and cooking systems. For veal cooked for 7 hours, we will wait later!
Privilégiez seasonal vegetables (salad, tomatoes, etc.) that will help maintain a lower body temperature and above all, that are delicious raw.
Seggiate your fridge and freezer
A fridge caught by frost will use its engine longer. This will therefore increase your electricity consumption by up to 30% but also the heat it releases.
Clean your fridge and freezer will save you money. This will also reduce the heat in your home.
Change rooms
If you have a room that is facing north, take the opportunity to turn it into a room during the heat wave. Conversely, the rooms to the west and south overheat in the evening.
And create drafts between different zones.
Refresh the room with a wet sheet or a bottle of frozen water
Place a wet cloth high. This helps keep your interior fresh. Coupled with a fan in the early evening, this will help promote the evaporation of calories. On the other hand, remember to turn it off after about an hour. This is because the fan's electric motor produces heat.
The even simpler version is to directly wet your soil. But be careful, you have to make sure that it can withstand this influx of water. Otherwise it is water damage!
Work and facilities to protect yourself from the sun
After seeing the daily tricks to have a feeling of freshness in your home, let's now see what work allows you to go further to fight against the heat wave.
Solar films
This solution can reduce the effects of the sun's rays by up to 60 to 70%. They also have the advantage of being relatively affordable, easy to install, while letting in light naturally.
You will find many solutions on the Internet, with prices in the range of 8 to 20 per m². They are designed to block UV rays. Also look in your DIY store, it offers movies. This solution is financially accessible and allows you to have a significant gain in the event of a heat wave.
Improve its insulation (the State can help you, lacentrale-eco.com can advise you)
We often have the reflex to think about insulation for the winter. But a well-insulated house is also a way to fight the heat in the summer.

ADEME regularly publishes very interesting and technically accessible files. Feel free to visit their website.
Thought to review if necessary the insulation of your walls and maybe change your windows to switch to double or triple glazing. Thus, you keep the fresh night air in your accommodation.
Natural insulation has better inertia than mineral wool insulation. They have the same thermal resistance. On the other hand, natural materials have a greater "thermal phase shift" (10 to 12 hours for natural materials against 6 to 7 hours for mineral materials).
Thermal phase shift?
In summary, it is the ability, expressed in time, that materials put to curb the penetration of heat.
We therefore recommend insulation made of wood wool, hemp, cellulose or cork to fight against the heat wave.
In addition, this work benefits from various tax subsidies. We invite you to go directly to the FLAIR platform with independent advisors to accompany you or to the site of the Ministry of the Economy to find all the current aid.
Attention:
Choose the right professional to carry out the work. Many dubious companies surf on the tax economy to perform services that are not always very honest.
Block the heat outside with an adjustable sunshade (BSO) or an outdoor blind
In order to benefit from a beautiful brightness and an efficient energy efficiency, today's houses have an increasingly large glass surface. Very good idea for most of the year but real furnace during temperature peaks.
The best known and most effective solution to prevent heat from entering: the adjustable sunshade. To simplify, it is an outdoor vertical blind, but more modern, more resistant and offers better modularity.
The blades are adjustable to provide natural protection from the sun and UV rays. Conversely, they know how to be discreet to better control the brightness in your home. These blinds can be electric or manual.
They complement or replace Californian awnings or blinds and pergolas.
Shades adapt to both constructions and renovations. They can be installed for a renovation on a window, on a façade or embedded in a wall.
Agrim BSOs have the advantage of being lighter than wood, making them easier to motorize, all with limited maintenance compared to wood.
Canadian or Provençal well
Solution less known for cooling a home, the Canadian well (not a Canadian well) is the natural and ecological version of air conditioning.
To put it simply, the Canadian well cools the air that enters your home (in the summer) by passing it through underground pipes. It is coupled to your VMC.
Underterranean pipes are at earth temperature, i.e. about 14°. This is called geothermal energy.
It's like enjoying the cooler air in your cellar, but throughout the house.
On the other hand, the Canadian well warms the air in winter. This solution is often found in passive housing. It is hoped that the use of this Technique of the Canadian or Provençal well will develop in all dwellings to limit the use of air conditioning.
The Canadian well will lower your indoor temperature by about 5° in the summer. This will give you a pleasant feeling of freshness, without having too large a gap when you go out.
If you want to know more, you can contact Benjamin, our specialist or read this article very complete.
At the budget level, this installation, carried out for new homes or major renovations, will be coupled with a double flow vmc to get the maximum comfort and performance.
Veget your roof
Solution the most advanced and rare, this will act as a regulator of the temperature of the dwelling: it will reduce the heat in the rooms in the summer and isolate from the cold during the winter.
Though you need to hire a professional to seal and make sure your roof is able to absorb the extra weight.
It should also be known that the vegetation will also protect this roof, which will extend its lifespan. Investing in a green roof saves you energy.
