Planning sustainable buildings that are gentle on resources is our priority. Technique is not supposed to end in itself but to be as sustainable and energetically self-sufficient as possible, while reducing the energy requirement that remains after all resources of the technical potential of a building have been tapped. In order to provide the best possible solution for our clients, technical alternatives are compared with each other in detail to the point of creating building simulations by the help of Life-Cycle Cost analyses. 

In addition to investment and energy costs, maintenance and operating costs play a major role.
