Renovation of 160 houses from the 1950s: insulation and airtightness of facades and roofs, change of exterior joinery, replacement of kitchens and bathrooms. The facades and the roof will be manufactured off-site: the panels arrive with their insulation, waterproofing membrane, joinery, etc., and are directly affixed to the existing facade. This is the 3rd EnergieSprong renovation project in France, the fundamental principles of which are E = 0 renovation (homes do not consume more energy than they produce) guaranteed for 30 years; the works have a very short duration (1 to 2 weeks / accommodation) and in an occupied site; and massification makes it possible to considerably lower the cost of renovating a home.
Delivery of the final project is scheduled for April 2022.
Sustainable development approach of the project owner
This is an approach that completely breaks with what is currently being carried out in terms of energy renovation. With this renovation of 160 EnergieSprong pavilions, this project is a pioneer in this field in France.
This method of complete renovation in less than 3 weeks (per unit) will achieve 0 energy and this, guaranteed for 30 years.
Thanks to the use of digital tools, study times are reduced. The structural elements being prefabricated in the factory, transformation is possible over a short period of work.
It was originally a European project, currently the most important in France, which, on the strength of its success, tends to develop rapidly throughout the world.
Architectural description
The district includes 160 houses from T4 to T8, made of brick.
The “Energie Sprong” concept implemented on this operation allows a project to be carried out smoothly.
All the houses are “encapsulated” thanks to the prefabricated brick-finish facade modules.
Roof-mounted solar power plant and entrance maintenance module are the visible parts of the project.
The variation of brick shades contributes to the renewal of the neighborhood's image.
Building users opinion
The consultation of the inhabitants resulted in favor of the project. The main fears concerning the veracity of the announced performance and the stopping of gas for cooking. On another EnergieSprong project carried out, residents expressed their great satisfaction with the services provided and the improvement in their living comfort.
If you had to do it again?
If it had to be redone, the diagnosis before work should be more precise in order to avoid unpleasant surprises, such as crawl spaces to be isolated, inaccessible.

More information
The real consumption per dwelling before renovation is estimated at 18,000 kWhef / logt / year. After renovation, consumption will be 5500 kWhef / logt / year. The annual production of photovoltaic electricity per house will be 6000 kwh / logt / year. Over a year and for 30 years, housing produces as much energy as it consumes.

The LG 370W solar panel is a high efficiency 60 cell photovoltaic panel thanks to its back contact technology. This system of bars attached to the back of the cells allows it to capture the sun's rays at the front and back of the panel to produce more current. The NeonR 370W is therefore a high performance panel for a reduced size, it is ideal for a performance search with a limited space. LG offers the highest product warranty on the market with 25 years of warranty. The LG NeON® R panel has bus bars attached to the rear face of the cells. Thus, the entire front of the cells is exposed to light in order to produce more current. With 30 busbars on the rear side, compared to the traditional 3 or 4 busbars on the front side of the cells, LG not only presents an innovative design, but also an aesthetic design. This innovation allows the module to achieve extremely high performance. The LG NeON® R has an extended performance guarantee. After 25 years, LG guarantees at least 88.4% of the original performance of the LG NeON® R. During the development of the LG NeON® R, the design was particularly careful. The front face of the cells, without an electrode, produces an aesthetic effect that can increase the value of a building. Thanks to an improved temperature coefficient, the performance of LG NeON® R is better on sunny days. During the development of the LG NeON® R, the rate of return was greatly increased. It is therefore particularly well suited to exploiting limited areas. The new reinforced frame design allows the LG NeON® R to withstand pressure up to 6000Pa and suction up to 5400Pa.

Il s'agit ici d'une approche en rupture totale avec ce qui est menée actuellement en matière de rénovation énergétique. Par cette rénovation de 160 pavillons esptampillés EnergieSprong, ce chantier est précurseur en dans ce domaine en France.
Cette méthode de rénovation intégrale en moins de 3 semaines (par unité) permettra d'atteindre une énergie 0 et ce, garanti pendant 30 années.
Grâce à l'utilisation des outils numériques les délais d'étude sont diminués, et les éléments de structure étant préfabriqués en usine, la transformation est possible sur une courte période de travaux.
C'est à l'origine un projet européen, actuellement le plus important de France, qui fort de son succès, tend à se développer rapidement à travers le monde entier.
