At institute for buildings and energy the goal in teachings and research is pursued of maximizing the energy performance of buildings by optimisation of the form and construction. Energy-efficient architecture is understood as a triad from minimum energy consumption, optimal room climate and architectural quality.

Substantial main points of research are investigations regarding the relationship between building form and energy efficiency. The early employment of technology during the system design in terms of computer simulation, can mean e.g. the prevention of technology such as air conditioning systems in the ready-made building. On the one hand these computer simulations form the methodical emphasis of the research. In addition they are used as teaching materials to illustrate the thermal and energetic procedures in buildings.

Current research projects are: "Form follows Energy", "The Role of Tall Buildings in the Sustainability of European Cities", "Energy-efficient ventilation of office buildings" and "High Technology Double Skin Building Envelopes".
