Having transferred some teams earlier this year to its new Excellence Center in the Oise, Air Liquide Welding is now moving its other teams in Cergy Saint Christophe. Construction of the new 4,500 m2 building has just been completed and has been designed and built to match the eco-responsibility requirements of Air Liquide Welding. Many devices are in place to reduce the carbon footprint of the new premises, such as intelligent lighting control and programming of open / close blinds shutters. Similarly triple glazed windows improve insulation and heating / air conditioning of the building is centrally managed allowing individuals the ability to adjust the temperature on demand. The HEQ certification of the building is in progress. Fittings offer a functional and ergonomic working environment for the sharing and efficiency between teams in order to meet customer requirements.
