Two months before the Conference of Parties on Climate Change (COP21), the city of Paris aims to make residents and citizens aware of the energy transition by sponsoring the exhibit “Paris of the Future” consisting of 80 concrete innovative solutions. Located on the banks of the Seine, the Bassin de la Villette, on Winston Churchill avenue and the square in front of the Hôtel de Ville, the exhibit will last until 14 December .

Aware of the increasing popularity of alternative means of transportation, the architectural firm Atelier Juno is introducing its “Shelter” project. Specialising in the use of 3D technologies and the creation of digital models, the firm designed a closed compact bike shelter (2.5 m x 2.5 m) that could accommodate up to 30% more bikes than a conventional shelter . Given its size and its modularity it can be installed temporarily during events and demonstrations. The firm Juno also has plans to propose it as a bike storage shelter for individual users.
Rag concrete: a recycled and recyclable covering
Combining design and the circular economy, the Rag Concrete project offers a decorative acoustic corrective material made from recycled textiles. Introduced in 2013 by the collective Prémices, a young Parisian startup, it has been supported since 2014 by the eco-agency for Textiles, Linen and Shoes (TLC in French) and ADEME.
The project involves recycling textile waste into an acoustic covering with the fibres smoothed out, giving it a mineral-like look close to concrete. Rag concrete can be applied to all types of walls; it is also recyclable, which makes it an example of the circular economy.
Heating a city using its wastewater
With the innovative solution Degrés Bleus [Blue Degrees] developed by SUEZ, the heat from wastewater systems can be recovered to heat and cool all types of buildings. Wastewater actually has an average temperature of 11 to 20 °C year round, thus representing a major source of renewable energy in the heart of the cities.
Degrés Bleus consists of a heat exchanger installed in wastewater systems from which it collects the calories, which are transported by a heat transfer fluid to a heat pump.
The process was inaugurated in 2010 in Levallois-Perret (in north-western Paris), where it heats the aquatic centre, resulting in a 66% reduction in greenhouse gas emissions and a 24% reduction in energy costs .
In the area “Water serving the urban energy transition” SUEZ is also presenting a turbine power plant producing electricity from drinking water systems and a smart watering system that can save as much as 30% on water.
Among other initiatives to learn about: energy paving stones, a depolluting concrete, a 100% electric boat, and more.
Paris of the Future will be held at the following locations:
– On the banks of the Seine from 9 August to 4 October
– At the Bassin de la Villette from 18 November to 14 December
– On the square in front of the Hôtel de Ville from 30 November to 13 December
– Avenue Winston Churchill from 4 to 11 December
