Energy-intensive building

These are 8 cottages that have come replaced the furnished canvas bungalows aging and without insulation.
They required the implementation of nearly 800 pallets. The pallets are called "white" that is to say they were removed from the logistics after a few transits, and were sourced from a Occitan recycler. The bracing is made from 15mm OSB 3 Hydro slabs used as interior facing.
The insulation of the floor and ceiling is achieved by the implementation of blown cellulose wadding boxed in OSB 3 22mm.
The walls are insulated from the outside via compressed wood wool panels that carry the function of a rain screen. The frame is made from I-type Swelite I220 beam which provides a slight slope towards the rear of the building.
The cladding is composed of a raw larch veneer from a local supply-short cycle, sawmill Bois du Rouergue being located less than a kilometer.Il is mounted in clear, 12cm vertical blades wide being covered by other 15cm blades.
They were made by an international team of 8 people (consisting of a Chilean, a Belgian, a Moroccan and French) in 19 days only with unclean weather (rain, hail and snow).
Intended to host green classes in the league of education of Aveyron, these chalets were equipped with ten beds and cupboards each.The electric octopus is composed of 4 catches, two lighting with comings and goings, of wiring for the installation of a radiator, and a reserve for the emergency block.

Sustainable development approach of the project owner

The objective was to replace 8 furnished bungalows of 25m² that can only work in the summer months with wooden structures to accommodate 3 seasons. The holiday center is composed of wooden chalets and a few mobile homes A first mobilhome that served as a bungalow animation was replaced last year (2018) by a pallet structure that gives complete satisfaction.

Compared to other constructions, the difference is in the time of realization between the order and the commissioning. The benefit of a dry site avoided having a dirty site and allowed to continue operating the center during the works.

Architectural description

The structure came to rest on existing concrete slabs of 5m x 5m, so it was important to be adapted to the dimensions of the slab. The Anse du Lac Holiday Center is installed at an altitude of 800m and wishing not to have to perform maintenance on the cladding, the choice of larch has naturally imposed itself. The "rough sawing" finish was chosen for aesthetic reasons and a desire to keep a "roots" spirit. Two particular demands were made on the roof with the principle of a roof overhang on the front of 70cm and a slight slope towards the back. The chosen materials had to be as "natural" as possible and the choice of wood wool and cellulose wadding for insulation suited the expectations.

Building users opinion

favorable reception, feeling of well-being

If you had to do it again?

A concrete slab of 70m ² was planned for a new installation on the edge of lake object of the other elements of architectural description.

Reasons for participating in the competition(s)

La rapidité d'exécution a été un des points forts de cette construction dont la mise en service devait être inférieure à un mois.Ces 8 chalet ont été réalisé en 19 jours de travail avec une équipe légère de 8 personnes en moyenne et sans outillages spécifiques ou moyens lourds (pas de grue, ni d’échafaudage). La volonté de s'inscrire dans un schéma de recyclage était également un point fort attendu du client et la revalorisation des palettes pour construire l'ossature était discriminante.La mise en œuvre de circuits courts et de faire travailler les entreprises locales était aussi un point fort, disposant d'une scierie à moins d'un kilomètre nous avons pu confier l'approvisionnement des bois de bardage en Mélèze à ces derniers et approvisionner les autres matériaux dans la Région Occitanie.
S'agissant d'un chantier sec, le chantier n'a pas perturbé la vie du centre de vacances dans l'environnement et a généré très peu de déchets, ces derniers ayant été revalorisés au sein de la filière bois locale (granulés bois de chauffage pour certains produits et nichoirs à oiseaux pour les chutes de mélèze). L'équipe a été formée à la technique constructive au cours de la première semaine, s'agissant pour le formateur de s'assurer de la bonne compréhension de la technique constructive SYLCAT à base de palettes.
