It goes without saying that we treat our natural resources responsibly. We strictly observe that only non-polluting means are used. Knowing that an intact environment is our most valuable possession offering us a maximum of health and well-being, we bet on consistent minimizing of emissions and minimal consumption of resources. To illustrate that, we have large solar installations on our buildings which contribute to a non-polluting production. The materials we use guarantee a healthy room climate and are of harmful substances.
