The adobe technique (raw earth compacted in a formwork in successive layers using a pestle (or dame, pisoir, pisou) is a technique for implementing the ancestral earth material, used in works that are several centuries old. around the world and some of which, in a perfect state of conservation, are classified as World Heritage by Unesco. In recent years, we have witnessed a revival of this technique in new buildings, public or private, with contemporary architecture. and this in particular for its multiple aesthetic, physical and ecological qualities.

The dividing wall between the two dining rooms made of adobe makes it possible to bring material, a non-smooth wall into the spaces: this is a real plus for the acoustics of the rooms.

Life Cycle Analysis

Eco-design material :

The wooden frame is the main construction method for this project. The construction system mainly uses elements coming directly from the local wood industry, most often used raw, solid and relatively unprocessed, in a search for economy, simplicity and durability, and enhancement of the natural material. We will try to avoid, as far as possible, the use of glued laminated timber.

The geographic location of the project calls for the use of this biosourced material. It is the local resource par excellence, not only present nearby in local forests, but also sawable nearby. We propose on this point to prescribe a supply with local woods answering at least to the label "Bois des Alpes" and by trying to guarantee the most local origin of the resource and the place of its transformation. This approach makes it possible to stabilize jobs on the territory of our projects, while guaranteeing the quality of the wood used and limiting the carbon footprint of the project. The wood will mainly be present inside, in the structure of the curtain walls or on the underside of the ceilings.

The raw earth is found on the west facade in the form of rammed earth and for the wall separating the elementary room from the nursery rooms in the form of coated raw earth bricks. In France, earth as a construction material is widely used throughout the territory in the built heritage. The rammed earth technique is a technique for implementing the ancestral earth material, used in multi-centenary works present throughout the world and some of which, in a perfect state of conservation, are classified as World Heritage by Unesco. In recent years, we have witnessed a revival of this technique in new buildings, public or private, with contemporary architecture, and this in particular for its multiple aesthetic, physical and ecological qualities.

The use of raw earth in construction is all the more relevant as specialists in sustainable development and environmental impacts in the field of construction point to industrial materials with high energy production costs such as cement and steel. Rammed earth is a mineral material with high inertia, close to concrete in its structure and composition, but using only raw materials. Today it is a real alternative to all-concrete construction. Its other great quality is its reversibility. Indeed, without the addition of chemical binder, this material is infinitely recyclable. It does not lose its mechanical, hygrometric or even aesthetic characteristics.

These intentions lead to the definition of interior atmospheres resolutely dominated by matter: it feels, it touches, it sees. All these principles are part of a frugality approach aimed at minimizing maintenance costs over the long term, while providing optimal comfort for future users. We wish to favor the use of the "right" material, thus, the very demanding parts of the building (technical rooms) or in contact with the ground are made of concrete in order to be able to protect the biosourced envelope coming to rest on this base, ensuring thus its sustainability and its foundation.
