Energy-intensive building

The eco-citizen project cuts across different services areas to population:

  • Catering (early childhood, school and elderly)
  • Childcare facilities to childhood and early childhood (nursery and leisure centre for after-school activities)
  • and practice of cultural activities and sports by the construction of a multi-activity building for local associations and schools.

This project takes place in a bioclimatic building connecting outdoor spaces with a quality educational garden and many public spaces.

Special care is given to the integration into the site, by the choice of materials as well as proportions of its different components, without neglecting the aesthetic transition with surrounding elements, especially the ancient village.

Sustainable development approach of the project owner

The eco-citizen project Pierrevert is a multi-use public building, in time as in functions. The client wanted a new kitchen suitable for the preparation of fresh local products coming from organic agriculture. In addition, a new nursery was built close to the city center and the school.

Architectural description

The project has integrated an environmental approach to control the project management from the conceptual design phase. It was inspired by the "Environmental Quality of Buildings", a regional (PACA) charter, known as CodeBaQuE. The architects agency has responded to the program, while integrating the constraints and challenges of the site. The bioclimatic architecture, renewable energies and a strong presence of vegetation largely contribute to the definition of a Mediterranean and sustainable construction.

Building users opinion

Excerpts words:
-"I have never been that hurry to come back from vacation! kindergarten director, Emmanuelle Hollender in Marseillaise
-" We are close to paradise! " At the opening ceremony, Ms. Dominique Bertinotti, Family Minister
-"The cafeteria is great! There is color everywhere, blue, purple, yellow ... so I find it really beautiful!" Gaston 4 years

Urban environment

  • 6 000,00
  • The building surrounds the town center, next to the existing school group. The land has a steep slope greater than 11% northeast oriented. It was already occupied by a two-way service road and a parking area for about 40 cars. The newly created buildings are located in the high part of the land which required significant infilling works.

    The modules are perfectly integrated into the roof and fit into the contemporary architecture of the project while remaining discreet with the landscape and patrimony. These panels ensure the tightness of the buildings and contribute to the educational purpose of this eco-citizen space.

Comfort

    The use of bio-based materials to create a very healthy environment for children with low emissive materials. The design of the building has created an outwardly strong link with constant views of the landscape and child-friendly, but also accessible gardens and terraces where children can eat. It thus captures both the views and natural light thanks to generous glazing as well as sunscreens systems that help maintain a qualitative summer comfort. In a building with high performance envelope , natural ventilation or double flow systems and air blowers optimize quality and renewal of healthy air.

Reasons for participating in the competition(s)

By participating in the program "Acting for energy" of the PACA region, the project aims to develop comfort to users while providing the more sustainable possible architecture. Thus, the sustainable approach has gone through a design consultation with residents and users, the use of renewable energies and bio-based materials, with particular attention given to outdoor spaces up organic meals served in the school cafeteria developed thanks to the production of local farmers.It is therefore a global thinking which helped to build a positive energy building respectful of its environment, but above all of its users: an eco- citizen project. The project got the Gold level of “Mediterranean sustainable buildings approach” (BDM).
