Against the predominant background of global warming, rapidly diminishing energy resources, exponential population growth, increasing geopolitical instabilities resulting from the uncertainty of the future energy supply situation together with the fact that buildings are responsible for at least 40% of the world's energy consumption, good architecture is not possible without a good energy concept. Buildings represent a large part of what is probably one of the biggest problems of our society - namely the fair distribution of the resources available to us. Architecture can therefore be a major part of the solution. Never before has this discipline been offered a comparable opportunity to play such a central role in the history of mankind. Good architecture is always a concrete expression of the cultural values, priorities and hopes of a society. But now it can also provide the physical answer to this existential challenge. By definition, sustainable development cannot be accompanied by a simultaneous loss of architectural quality in our built environment. A building with little architectural quality and a good energy concept therefore makes no real contribution to a sustainable future. Research and teaching at the IGE focuses on maximizing the energy performance of buildings and cities and developing architectural and urban design projects that are inherently highly energy efficient by optimizing their shape and structure.

    Architecture is not only responsible for a large proportion of the world's energy consumption - architecture is energy. A line on paper that represents an architectural intention often implies decades or centuries of associated energy and material flows. At the Institute for Buildings and Energy (IGE),  energy-efficient architecture is understood as a triad of minimized energy consumption, optimal indoor climate and excellent spatial qualities - both at the urban and individual building level.


    The experience and the accumulated know-how from the practice of the consulting firm Energy Design Cody through collaborations with architectural offices such as Coop Himmelb(l)au, OMA, Miralles Tagliabue, Delugan Meissl, MVRDV, to name but a few, flow back into basic research but also into the teaching activities at the institute via lectures and impulse lectures, so that students benefit directly from this experience and knowledge.


    Since 2010, the concept has been to prepare a special topic of focus for the coming academic year with the aim of focussing attention in teaching and research on a specific topic for a limited period of time and to exploit synergies between the various activities. At the end of the year, the results of the teaching and research activities are summarized in a brochure and presented to all members of the faculty together with the chosen topic for the coming academic year.

Smart Facade - Energetic Potentials of Adaptive Facade Systems




The building skin as the "system boundary" between the interior and exterior environment is essentially responsible for the input or reduction of room loads and thus for a comfortable indoor climate, which should be maintained as energy-efficiently as possible. It is therefore desirable that the building skin should have a pronounced ability to adapt to the environment, to conditions in the interior and to user behaviour. Up to now, almost all building facades have largely fixed properties, which can usually only be changed in a few steps in a simple manner and thus do not meet the complex requirements. There is a need for optimisation with regard to a more precise reaction to temporally variable influencing variables. The aim of the work is to determine which properties an ideal building envelope should assume under which conditions and at which time. The energetic potentials of "smart", adaptive facades, which achieve maximum energy efficiency and maximum comfort through the possibility of variable physical properties, are systematically investigated. The "smart" façade concept uses weather forecasts, predicted future user behaviour (based on past experience and using an integrated approach of artificial intelligence) and current requirements and boundary conditions to assume physical properties that lead to energy-optimised performance and comfort for the user. A novel and innovative dynamic simulation model will be developed especially for this project. The study serves as a basis for the development and implementation of new building envelopes and their control in different climatic regions with partners from science and industry.
