The concept of “Green Hospital ” combines the goals of medical quality, economy and ecology in the operation of a hospital. For that the VDI Center for Resource Efficiency offers in several short films practice examples. The first film shows the integral measures at the University Hospital Freiburg in Germany. The clinic focuses on integral material flow management that includes many different resources. It has its own power supply and operates a combined cycle power plant and uses among other renewable resources such as wood pellets. Solar panels on the roofs of buildings and a sophisticated facility system, which turns heat into cold, form a complete green energy supply.
