Sustainable use of resources as well as environmental friendly products have always been part of our company philosophy. More and more, sustainability is reflecting the complete life-cycle of buildings – from planning to demolition. Globally, systems for the evaluation related to the certification of sustainable buildings have been developed: Leed, Breeam, DGNB and others. Moreover, single building components are assessed according their sustainable effects. Environmental product declarations (EPD) will provide information on the functional and ecological quality of the components.
