Summer has now become synonymous with extreme heat, especially in cities. The incandescent concrete, the asphalt that ribolle and the absence of vegetation transform urban areas into real open -air ovens. An increasingly frequent situation, which can no longer be ignored.
In front of such a scenario, Many rely on air conditionersignoring the environmental impact they involve: very high consumption, use of refrigerant gases and increase in the city’s electrical load. But an alternative, sustainable and brilliant solution exists. It is the Bamboo prototype designed by the Arep grouppresented at the Soul Biennale in 2021: a system of Adiabatic cooling or evaporative cooling that does not require neither electricity nor coolantand still manages to lower the temperature effectively.
Simple, silent, brilliant
At the basis of the operation of this device there is a natural physical principle: thewater evaporation. The water, coming into contact with the hot air, evaporates and absorbs the heat present in the environment. This natural process, known as adiabatic effectallows you to Lower the surrounding air temperature even of 6 degrees.
What makes this project really interesting is his total absence of electrical power supply. No engine, no fan, no noise: only water and airwith the support of A structure made of bamboowhich channels and optimizes the process. It is a perfect solution for the urban context, but also easily replicable in schools, courtyards, markets, public transport stops or pedestrian areas.
The bamboochosen as the main material, it is not a random choice. AND local, natural, cheap, light, robust and quick growth. In Vietnam, where the first prototype was made, grows in abundance and is widely available. Its processing requires very little energymaking it ideal for a project that aims to Maximum environmental sustainability.
Not just cooling
The Arep project is not limited to cooling the air. It was also thought of how a multifunctional urban structurecapable of create shadowimprove the urban landscape and offer pleasant and silent parking spaces. In a world increasingly invaded by complex technologies, this Low-tech solution represents a concrete response to the need for livability in cities.
The device, in fact, not only contributes to lowering the temperature, but invites you to slow downto better live public spaces. It can be installed In a square, in a school, in a playground or in a waiting area. And it does not need complex plants or maintenance: they are enough a water tank, some time and the heat of the sun.
In 2021 a prototype in Vietnam was successfully installed, one of the countries most affected by the climatic crisis. But it can be reproduced everywhere. Its effectiveness and simplicity make it perfect for integrate urban green, contrast the heat island effect And offer collective well -being without any negative impact.
Perhaps it is precisely from these projects that we should start again :. Air conditioners are not needed to live better in the summer, but more respect for nature and for the rhythms of our body. And maybe, even a little bamboo.
