In this paper various methods for reducing the heating energy consumption and two types of daylighting systems will be presented. These methods were applied as part of a research project conducted in the student's living quarters in Stuttgart-Hohenheim. The six buildings comprising a complex near Hohenheim University are oriented north-south. In order to improve the thermal insulation the buildings were covered by earth mounds on the north side (U-value 0.35 W/qmK) and plants were grown on the roof. The large window areas towards the south function as solar collectors; the energy gained can be stored by suitable materials in the floor and in the walls. Four of the buildings (A-D) are four storeys high, two otheres (E,F) are three storeys high (figure 1 and 2). The buildings were fitted out with different energy saving components, allowing interesting possibilities for comparison. A comprehensive measurement and regulating programme provides information on the efficiency of the measures . This has been assisted by a sociological-empirical programme with questionnairs and interviews carried out by the Fraunhofer-Institut für Systemtechnik und Innovationsforschung.
