Product category : Structural work / Structure - Masonry - Facade

Elegant and designed, openwork wood cladding permits various effects. Retification allows for Poplar, traditionally highly putrescible, to become a perfectly suitable essence for cladding. RETIwood Poplar, like other essences, is the subject of a specific supply mainly French.

Construction and exploitation costs

• Cost of studies : 1 170 000 €
• Total cost of the building : 21 400 000 €

Indoor Air quality

Aqueous solvent-free paints were systematically used with heavy-metal-free mineral pigments. European Ecolabel was demanded, except in case it was impossible for the type of paint. Values ​​2010 European Directive 2004/42 / EC 4 on the limitation of VOC (Volatile Organic Compounds) are consistently met.

We banned even labeled:
- The products containing more than 2.5% of organic solvent and / or a VOC (volatile organic compounds) greater than 1.5 g / l of product.
- Products containing pigments based on heavy metals (lead, cadmium, chromium).
- Products containing glycol ethers classified as reprotoxic class II.

Floor coverings:
The falls have been recovered and stored in big bags and collected by the supplier specifically with recovery certificate. PVC flooring
proposed must contain a minimum of 25% recycled material. Other types of soils were subjected to validation E. VOC and formaldehyde emission rate of these products are known and communicated to BE HQE. Flooring manufacturing factory certified ISO 14001.

Indeed, for the housing of the residence, the floor is PVC-type category UP4 (recycled and natural) with zero tolerance vis-à-vis the emissions of volatile organic compounds. For commonplaces (movements, in living areas, ...), the majority of soil is tiled so no VOC emissions.

"Our childcare center: a healthy space, a space of life"

The coating of the crib will be without emission of volatile organic compounds and artificial green spaces are antibacterial certified to ensure good health of children who occupy it. These supports are specially designed for use in a nursery. Artificial grass is fire resistant, tear and easy to clean.

The murals are also certified VOC.

GHG emissions

• GHG in use : 21,00 KgCO₂/m²/an

Life Cycle Analysis

Eco-design material : The openwork wood cladding used on the international residence and the childcare center is made of retified poplar. Traditionnally very putrescible, poplar transforms into a very suitable essence for cladding, once retified. The wood use din this building is healthy, treated against fungus and insects. It complies with CE, NF, FSC, PEFC, CTB.
