83% of the 1.4 billion € loans from CDC’s savings funds in the Hauts-de-France are for social housing.
69 million € invested in 51 projects planned in the Seine Normandy Agglomeration until 2021.
27 TWh Renewable energy production target (12% of consumption) in Hauts-de-France by 2020.
The countdown is on: the next European Solar Decathlon (1) will take place in fifteen months in Budapest, Hungary. France will be represented by the Habiter 2030 team, made up of 14 schools and universities in Hauts-de-France (2). This consortium is led by the Ecole nationale supérieure d’architecture et de paysage de Lille (ENSAPL) and the Compagnons du devoir. Its aim is to build a real size house, eco-responsible and powered by solar energy. And above all, to stand out from the 15 other teams in the running.
“We are going to work on the rehabilitation of the terrace town house, a typical habitat of the region built during the industrial era,” explains François Andrieux, director of ENSAPL. There are 400,000 houses of this type in the Lille metropolis, one million in the Hauts-de-France: the stakes are considerable. “The “1930 house” is synonymous with energy waste. “The contest requires us to find a 100% solar solution,” notes Jocelyn Gac, coordinator for the Compagnons du devoir. But as sunshine is not the strong point of the region, we will explore all the solutions that can be integrated into this energy choice. »
Solar urban block. The reflection will focus on the sharing of energy production and consumption between houses on the same street or block. Another principle will guide the design work: each device will have several functions. “For example, insulation will have to be used for another purpose: this commitment will require a lot of creativity,” says Jocelyn Gac. Nearly 200 students and educators will build a prototype in Lille, reproducing the thermal properties of the town house. This scale model will be dismountable, to be exhibited in July 2019 in Hungary, before returning to the region. “We want there to be life after Solar Decathlon,” says Béatrice Auxent, president of Habiter 2030. This research-action will feed the reflection on the massive rehabilitation of the Hauts-de-France real estate stock. “Planners, social landlords, local authorities and economic players are also involved in the association.
Their support will be useful to finance a project valued at €2.4 million including tax. The students’ work will complement the initiatives taken in the region over the past ten years, such as the Villavenir Rénovation project of the French Building Federation or the Réhafutur project, a showcase for eco-renovation in the mining basin supported by the Cd2e cluster (for “Creation of eco-business development”). All good ideas are welcome: two thirds of the homes in the region date from before 1975.
Its goal: to design the best solar house in a defined time.
