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.

One key issue of our research is the relationship between energy efficiency of buildings and the buildings form. In order to achieve the social objectives towards the sustainable development of our environment, we know, that energy efficiency and ecology of each and every architectural project shall be on top of every planners agenda. If the diverse aspects of energy efficiency are being considering during the design process, new building forms may be found in architecture. This project focuses on the following research questions: What is the impact of the relationship between the form and the energy demand of a building? Does the inclusion of these considerations inevitably lead to a new formal language? Or is it possible to optimize the energy efficiency of a building regardless of its architectural style and without any effect of the intended architectural impression to achieve the social objectives regarding sustainability anyway? The relationship between architecture and energy will always exist. No matter if form follows energy or energy follows form, the energy efficiency of a building is significantly influenced by its architecture
