  • ABOUT

    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.

Description

At first sight a high rise building seems inherently energy efficient. The existing wind pressure in greater heights often makes it impossible to use conventional external sun protection and openable windows. That is why usually mechanical ventilation and air-conditioning are being applied and used all year round. Hence, strategies that allow natural ventilation of high buildings have a high potential to improve the energy efficiency. That is why the concept of the winning project of the competition for the new HQ of the European Central Bank in Frankfurt (Germany) consists of natural ventilation of the building only. This idea was then further developed within this research project. The following advantages may apply: greater energy efficiency during operation, reducing embodied energy, lower risks of sick building syndrome, reducing operating costs as well as costs for construction. The results were presented to the scientific community on the international congress in Kyoto, Japan in October 2008.
