23 May COOLING: WHAT RESPONSIBLE SOLUTIONS TO COMBAT HEAT PEAKS?
This month of May 2022, in France, is marked by a very high mercury due to a heat dome above our heads. A direct consequence of global warming, phenomenon that has also been observed in India and Pakistan.
Since the 1950s, heat peaks have become more frequent and more intense and these phenomena will continue. According to Météo France, we can expect twice as many heat waves in France by now. 2050.
So how to adapt to these heat peaks while preserving the planet?
- Cities, particularly vulnerable to high temperatures : Thes cities are directly impacted by climate change due to urban overheating. This refers to the effect heat island which is manifested by a limited nocturnal refreshment compared to the countryside.
- The use of air conditioning: Paradoxically, the use of air conditioning worsens global warming. According to a study published in 2020 written by researchers from the Ecole des Ponts ParisTech, if all Parisian households were equipped with an air conditioner, the power consumption average during a heat wave would be doubled, which would increase the temperature of the streets by 3 ° C compared to a city with no air conditioning system.
- How to adapt while respecting the planet: Faced with these episodes of high heat, it is therefore necessary to set up adaptation and prevention plans, respectful of the environment: revegetation of the building, choice of suitable building materials, reduction of the artificialization of the soil by promoting its porosity and by giving back a place to water...
GREEN SPACES TO BRING FRESHNESS
Very concrete environments favor heat islands. Indeed, some materials, such as asphalt for example, retain heat during the day and release it at night. In addition they are waterproof. The introduction of plants lower the temperature of several degrees thanks to the'shady, reflection of solar rays and the phenomenon of evapotranspiration. Cities have understood this and are implementing actions to bring back nature in the city and develop islands of greenery (Example of the city of Lyon which greens the streets and schoolyards to lower the temperature).
Below is the selection of Takagreen suppliers who have designed street furniture solutions for refresh thea city :
- Urban Canopy : Design of light structures to green the city
- E-tree : Design of urban furniture - island of freshness
In the continuity of cooling street furniture solutions, our partner supplier WaterConnect, also offers islands of freshness, of course unvegetated but working with a autonomous system guaranteeing low water consumption.
- Green roofs: Green roofs are excellent thermal insulators. The plant layer makes it possible to stop the rays of the sun and to evacuate the heat stored during the day thanks to evapotranspiration. It also allows to bring back the biodiversity in the heart of cities, Reduce the pollution and to promote The well-being building occupants. Consult our partner suppliers specialized in green roofs: Endland, Primrose Landscaping, Agrove, Vegetable workshop, Ecovégétal, Topager.
- Green facades: affixing plants to a wall helps to improve the insulation of buildings and is a solution for cooling and humidifying the air (phenomenon of plant evapotranspiration). It is also beneficial to biodiversity and improves air quality. Discover our partner suppliers offering this type of solution: Topager, Agrove et Manage vert.
IMPROVING THE ENERGY PERFORMANCE OF BUILDINGS
- Thermo-reflective resin : This reflective roof paint reflects 90% of the heat that strikes it and extends the life of the roof. This solution allows to maintain cooler air inside buildings (up to 10° in the hot season) and reduce the amount of air conditioning bills. Discover our partner suppliers Covalba et Enercool (ex Aircool) .
- Solar protection glazing: Solar protection glazing from our partner supplier immovable block out the sun in summer and let it in in winter. Thus, they improve thermal comfort and reduce energy consumption.
OTHER COOLING SOLUTIONS
