For the academy Mont Cenis in Herne, Germany, a large microclimatic glass envelope (72m x 1.80m x 15m) with separate buildings inside the envelope, a concept for the natural ventilation was put up and a program for the control of the motor driven windows in the facades and in the roof was developed. To comprise the influence of wind speed, wind direction and the temperature difference between the envelope and the environment, numerous CFD-calculations were carried out on the base of a wind tunnel test and dynamic thermal calculations. The thermal mass was in taken into account to avoid short switching intervals of the windows. A 10.000 m2 PV plant integrated in the roof avoids overheating in summer and the glass envelope leads to moderate temperatures in winter.
