JCDecaux improves urban life with its new Natural Cooling bus shelter

Paris, 9 July 2020 – JCDecaux SA (Euronext Paris: DEC), the number one outdoor advertising company worldwide, has developed and is now offering local authorities its new-generation Natural Cooling bus shelter, with a solution to the issue of urban heat islands. The new model expands the range of innovative bus shelters launched by the Group at the end of 2019. These include Filtreo, a bus shelter whose green roof contributes to reducing urban pollution.

Summers have become hotter in recent years. According to the World Meteorological Organisation, 2019 was the second hottest year on record after 2016. The WMO also noted that the average temperature between 2015 and 2019 was 1.1°C higher than in the fifty years between 1850 and 1900.
This rise in temperature has widespread consequences and leads to the formation of urban heat islands, which have an impact on cities and on the health and well-being of their inhabitants.

To help address this problem, a range of initiatives to create cooling areas in the city during the summer are currently being trialled. JCDecaux has developed an innovative patented solution to cool off people in its bus shelters, providing a sense of comfort and well-being during periods of intense heat.

JCDecaux’s R&D department took its inspiration from a natural, age-old process: evaporative cooling. Hot air entering the Natural Cooling shelter flows through a wet honeycomb-shaped panel. It is then cooled naturally by evaporation. This solution includes a tank to gather rainwater from the roof and a system to pipe the water to the cooling module. If there is no wind, fans blow the hot air through the wall. The cool air is then blown towards users waiting in the shelter. Solar panels on the roof produce the energy required. The real-time control system detects weather conditions and human presence in the shelter in order to function efficiently and only when required.
Combining solar energy with rainwater harvesting, this self-contained solution avoids the use of air conditioning with its high energy consumption. Unlike misting, the evaporation process presents no health risks since it does not create micro-droplets.

Natural Cooling acts as a sort of urban cooling oasis for the comfort and well-being of passengers. This effect is further enhanced by the use of untreated wood and light colours. The pergola-inspired design is friendly and welcoming. Passers-by are encouraged to step inside the shady interior and take advantage of the seats, which are inspired by interior furnishings.
