Space saving: integration slab. Hygiene: distribution ducts with patented principle of "double-skiN"; for easy maintenance and limiting the deposition of dust.

Construction and exploitation costs

• Total cost of the building : 8 500 000 €

Indoor Air quality

IAQ measurements made at the end of construction phase, before occupation and renewed after occupation. Results not yet available. Collaboration Médiéco - Suzanne DEOUX very early in the design phase and during the construction phase to validate the components used.

Comfort

Health & comfort : Regarding comfort, our ambition is to create a comfortable indoor amabiance for our employees and visitors. The principles key are: - Radiant heating, soft and uniform heat, immediately perceptible in all areas - Totally silent operation in summer and winter - no uplift displacement and dust in space. no perceptible air movement by the occupants - The air filtered by a double flow ventilation is blown at room temperature - Management of different components by an intelligent BMS concerning health. Our ambition is to contribute to a perfect in-door quality for the health of occupants. We focus on the quality of air circulation, ambient temperature, decrease odor, dust, pollen and parasites, the humidity and sound level - Daylight brought by exposure of the building and the glass partition to use in interior design - sunscreens - landscaping, choose plants and non-allergenic esssences tratement internal acoustic - Heating and raffraîchissment - internal materials selection - Custom IAQ
We brought along throughout the project, from the design by the Cabinet MEDIECO Suzanne DEOUX, recognized expert in IAQ.
