    Construction technique:

    The structural work is made in CLT (Cross Laminated Timber), which allowed to mount the complete envelope in eight weeks. This material does not release CO2 for its production but it has stored it throughout its life. CLT suppresses thermal bridges. Thanks to the size of the CLT panels, the number of joints is reduced and the airtightness is improved.

    Special techniques:

    > Double flow ventilation, yield> 83%.

    > Triple glazing, mixed wood / aluminum frame, global Uw = 0.88W / m2k.

    > Water management, 400m2 green roof and 15,000 liter rainwater cistern (flushing and cleaning of common areas).

    > Solar thermal panels for domestic hot water.

    > The main insulation of the envelope (facade and roof) is made of high density mineral wool 45kg / m3 over a thickness of 22cm. lambda = 0.035W / m2k.

    > The party walls are insulated by a 2 cm vacuum and 6 cm of HD mineral wool. The floor tiles between the dwellings are insulated with 6 cm of mineral wool HD

    > Airtightness n50 = 0.6 h-1
