Energy-intensive building

Engaged in an ambitious policy of innovation and sustainable development, the Municipality of Four (38) asked the help of the designbuildLAB AE & CC ENSA Grenoble and the Community of Agglomeration Porte de l'Isere, to accompany it in the realization of an ecoresponsible architecture demonstrator .

This project has an exceptional dimension because it is part of the National Strategy for Architecture to "transform the act of building of tomorrow". It allowed students in architectural mastery of LabEx AE & CC of the National School of Architecture of Grenoble (ENSAG), in collaboration with local construction experts and companies, to realize for the first time in France a project of architecture resulting in a real construction useful to a community rather than an ephemeral experiment . Another particularity, the user population of this kind of equipment was integrated throughout the process, from conception to realization.

The town of Four has embarked on a project to build a multipurpose local equipment that will serve the associations of the town, its citizens and those of surrounding villages. She wanted to involve architectural students in this project to create a strong social link between these future professionals of the act of building and the concrete concerns of its inhabitants and its elected officials. The realization of this project has allowed to initiate a unique educational project in France around training and research, to train the architects of tomorrow. The second challenge of this project is to include it in a sustainable development approach by proposing an ecoresponsible public building .

The House for All is composed of three building blocks : a meeting room, a toilet block and a storage room. There are three landscaped areas: a mineral square in the north, a patio in the west, and a promenade bounded by a hillock to the south.

Architecture integrates harmoniously into its context, both in the techniques and materials used and in the proposed uses. This respectful relationship with the environment is manifested by thoughtful solutions in the interest of efficiency and sustainability for a building that consumes less energy . The materials used in the realization of project are the concrete, the earth, the wood, the glass and the metal favoring as much as possible the use of local natural materials in a process of contemporary industrialized construction, thus taking advantage of the virtues of these two approaches to the act of building: ecology and economics . The project was made of clay, with a rammed earth wall (traditional local know-how), a double insulating wood wool and a facing adobe inside. It also gives pride of place to the wood material with a prefabricated wooden roofing complex and a burnt wood cladding on the ancillary buildings. Heated and ventilated thanks to a double flow ventilation connected to a heat pump, it is designed to provide a natural comfort to the users and to reduce as much as possible the energy consumptions and the carbon impact. Photovoltaic panels offset this low energy consumption to make it a positive energy building .

Sustainable development approach of the project owner

The Commune de Four is engaged in an ambitious and proactive policy of innovation and sustainable development. It is willing to opt for an exemplary approach in the construction / management of the municipal heritage. Already accompanied by a Shared Energy Council, she was able to optimize her energy bill. It has also just completed the exemplary renovation of its school group, particularly through the use of the digital model, a very proactive approach for a small town of less than 1,500 inhabitants.

Architectural description

The House For All is an associative room in Nord Isère. For centuries, people in this region have understood that their land is perfectly suited to adobe construction. Their vernacular construction cultures led to the (re) invention of contemporary concrete. After more than 100 years of ubiquitous concrete production, the Maison Pour Tous reintroduces and reinvents the inherent sustainability of the earth as a raw material, little transformed, for a contemporary implementation.

The project consists of a set of three buildings: an associative room, a technical room and a storage room, gathered in the heart of a landscaped landscaped area. To the north, a mineral square can accommodate large outdoor events. To the east, a slightly elevated base provides an overhanging view of football matches. To the south, the excavated soil for building foundations is piled up to create bleachers for a small amphitheater on a terrace and a winding walk. Nestled between the three buildings, a patio open to the west, with a bench and planted with a deciduous tree, provides a quiet space to enjoy the sunset.

In the rammed earth, an open plan, modular storage and rolling bars invite a variety of uses. A ceiling made of spruce acoustic baffles reduces the audible reverberation during large gatherings. Large roof ledges allow for the sun's path to passively heat the room in the winter or create shade to maintain freshness in the summer. Large openings with larch glazed accordion doors connect this space to each of the surrounding outdoor environments.

Building users opinion

The municipality and the inhabitants are particularly satisfied with the project but also with the participatory approach. The result is well beyond their expectations and they are very proud to benefit from an architectural demonstrator that enhances the technique of building adobe and will meet multiple needs associative, sporting, cultural with this equipment very versatile.

If you had to do it again?

This process of realization and innovative collective reflection is already reused with another class of students, in another municipality.

More information

The multipurpose rooms are not subject to thermal regulation, the thermal study was carried out via a dynamic thermal simulation with an objective of an envelope close to a passive level with the least possible heating need, a heating production via a heat pump and photovoltaic installation to make the equipment positive energy

  • The site of the project is located on the site of the Luminière stadium and the multipurpose room of Four. It is located northwest of the city center of the town - town hall and school - to which it is connected by a footpath, crossing the Parc du Galoubier. The land is bordered on its western and northern limits by the Rue de la Luminière serving the ZAC de Four.

    The plot is accessible by car from three entrances located on rue de la Luminière: two in the west, at the multipurpose room and the city stadium, a very occasionally open to the northeast, near the rue du Grand Curtil.

    In the North, the existing stabilized space has been redeveloped into a mineral space, to offer a large space that can accommodate large-scale events - flea market, vogue - while offering easy access for deliveries.

    Between the three built blocks, the pre-existing concrete slab of the former cloakroom has been redeveloped into a landscaped patio. It offers a privileged space in the West, with a draining planted surface allowing the recovery of rainwater roofing.

    To the south of the buildings, a landscaped mound, up to 2.00 m high and built with the foundation excavation lands, was carved to form a gentle slope facing the stadium in the east and a green theater in the north. turned towards the room. It isolates a quiet garden space in the West.

    Finally, a hedge planted on the western edge allows to isolate the site of the road.

Reasons for participating in the competition(s)

​L’architecture du projet s’intègre harmonieusement dans son contexte, tant dans les techniques et les matériaux employés que dans les usages proposés. Ce rapport respectueux à l’environnement se manifeste par des solutions réfléchies dans un souci d’efficacité et de durabilité pour un bâtiment peu énergivore. Il a été réalisé en terre, avec des murs en pisé, un double isolant en laine de bois et un parement pisé à l’intérieur. Il fait également la part belle au matériau bois avec un complexe de toiture en bois préfabriqué et un bardage en bois brulé sur les bâtiments annexes.
Chauffé et ventilé grâce à une ventilation double flux raccordée à une pompe à chaleur, il est conçu pour procurer un confort naturel aux usagers et réduire au maximum les consommations d’énergie et l’impact carbone. Des panneaux photovoltaïques viennent compenser cette faible consommation d’énergie pour en faire un bâtiment à énergie positive.
