Based on global warming, decline of existing energy resources, exponential population growth, increasing geopolitical instabilities which are the result of uncertainty of the future energy supply, together with the fact that buildings represent about 40% of total energy consumption worldwide leads to a conclusion that a good architecture is not possible without a good energy concept.


    The buildings represent the bigger part of one of the biggest problem of our society - fair distribution of available resources. Therefore architecture can be a big part of the solution. Never before in the history of our civilization architecture had such a chance to gain one of the central roles in the society. Good architecture is always representing the expression of the cultural values, priorities and hopes of a society. Now it can produce a physical response for the existential challenges.


    A sustainable development by definition cannot get along with the decay in architectural quality of our built environment. A building with low architectural quality and good energy concept is not an actual benefit for a sustainable future. The objective of research and teaching at the Institute is the maximization of energy performance of buildings and cities, and the development of architectural and urban projects through form and structure optimization toward energy efficiency.

The building skin as a system boundary between the internal and external space is highly responsible for the gain or reduction of loads and hence for a comfortable indoor climate, which shall be maintained in the most energy efficient way as possible. Therefore, a building envelope that is adaptive towards its environment, the internal conditions as well as the occupants behavior is desirable. So far, almost all building facades consist of fix properties which usually are only changeable in a simple manner and in few levels only which is not sufficient to fulfill the complex demands. It is important to optimize the exact reaction of temporally variable influences. This research aims to determine, which properties an ideal building envelope should adopt depending on the conditions and time of the day/year etc. The energetic potentials of so-called smart facades or adaptive facades are being analyzed, which shall achieve the maximum possible energy efficiency providing the maximum comfort through the possibility of variable physical properties. The concept of the smart facade is using weather forecasts, predicted prospective occupant behavior (based on past experiences and by means of an integrated approach of artificial intelligence) and current requirements and boundary conditions to adopt physical properties that lead to an energetically optimized performance as well as comfort for the user. A novel and innovative dynamic simulation model is being developed specifically for this project. This study shall be the base for future developments and the implementation of new building envelopes and their control in different climate regions with scientific and industrial collaborators.
