Energy-intensive building
  • Certified BBC Effinergie
  • LQE 2013 prize winner

The conception and design of the building were lead by one strong wish: to give priority to wood material usage, equally on the structural, the envelope and the esthetics levels. The use of wooden structure and cladding, encasing cellulose wadding, allows to limit the energy needs of the building, thanks to thermal inertia of wooden material.

The project meets several criteria of the HQE ® approach:

  • the relation to its environment,
  • the choice of materials,
  • the water and energy management.

Other criteria such as mobility, bioclimatism, value to products and local knowledge are also representative of the project.

Hygrothermal comfort
- Efficient insulation
- Air-tightness, reduction of thermal bridges
- Unglazed windows sills to avoid feeling of cool walls
- Nighttime over-ventilation
- Cooling by groundwater
- Sun-Breaker

Acoustic comfort
- Buffer space between classrooms and activity rooms
- Walls' acoustic insulation and flexible floor coverings.

Visual comfort
- Natural light in all rooms
- Two lighting areas per classroom.
- Views on the surrounding landscape
- Dynamic and bright shades of the walls

Low environmental impact building site
- Prefabrication of wood-frame walls
- Local companies

Miscellaneous: 240 m2 of photovoltaic panels

Architectural description

The conception and design of the building were lead by one strong wish: to give priority to wood material usage, equally on the structural, the envelope and the esthetics levels. The use of wooden structure and cladding, encasing cellulose wadding, allows to limit the energy needs of the building, thanks to thermal inertia of wooden material.

Orientation: North-South
Architectural volumetry on scale of site and children
