Energy-intensive building

This building office and storage uses only wood structure 110m3. Its format is similar to a gymnasium, its thermal performance allows it to be Minergie labelled. With its simple skeleton, we can easily imagine transform it into an office or dwellings.

Its flat roof without bitumen or PVC allows rainwater recovered without polluting. Its implementation, structure, insulation, finishing are made only from materials ecological wood, hemp, cellulose wadding earth .... or only solutions with low impact and easy to recycle envionmental.

This type of building high-performance, requires very little energy for its operation, thus avoiding oversized electrical infrastructure.

Tenants live in an environment without air pollutants (with natural materials), or electromagnetic, all solutions being shielded wire.

Sustainable development approach of the project owner

This ambitious project has been designed so that it is easily reproducible. The aim was to show that it is feasible to achieve a high performance building (Minergie) validated by a third party using only environmentally friendly materials, framing and insulation vegetable and natural finishes, plaster, clay, paint .... Efficient solutions lighting (LED only) or hot water (solar) can have a ridiculous consumption of electricity. Obviously, the heating is wood. Air tightness of n50 = 0454

Architectural description

The project is parallel to the Loire, since it is an obligation. Office offered the part south allows solar gain have important choice of finishes on these parts gives pride to the local woods, Douglas fir and chestnut.
