The exploitation of symbiotic relationships and synergies in the development of the energy systems is an important aspect of the concepts we developed for the new campus of the medical University of Graz, in collaboration with the architects Riegler Riewe. Deceptively simple strategies can save considerable amounts of energy and resources. In the laboratory areas, a system was developed which employs the supply of cooled air and the use of reheaters to meet the individual demands of the laboratory spaces instead of the conventional HVAC system type utilized in Central Europe with isothermal supply air and secondary cooling systems, ensuring a greater utilization of free cooling and thus saving thermal energy and increasing energy performance. The floor plan is so configured that the office spaces and write- up areas are positioned in the regions with the best daylight conditions. The daylight openings in the façades in the lab areas are provided at two levels, at mid-level to provide views at the write-up areas and at high level to provide daylight to the laboratories behind. the configuration and size of the openings in the façades depends on the specific location within the dense urban structure and the use of the spaces behind the façade. The offices are naturally ventilated and heated and cooled via suspended radiant ceiling panels. On account of wind considerations related to microclimate the buildings are orientated with the long axis running north-south. The external shading devices were therefore designed as automatically controlled vertically aligned perforated metal elements which allow daylight and views while blocking solar radiation.
