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.

Impact of a Potential Climate Change on the Energy Demand for Heating and Cooling of Buildings

Whilst the focus of research at the institute lies on the development of strategies to maximize the energy efficiency in the context to contribute towards the reduction of global warming, an interesting question arises considering the apparently inevitable climate change, how buildings must be designed to function in the expected external climate. This research project analysed the question as to what extend the forecast climate change may impact the energy demand for heating and cooling of buildings in Austria. Two aspects were looked at: a possible rise in temperature and a potential increase of the CO2- content of the ambient air. Interesting technical consequences for future energy supply of buildings were shown. An interesting result on the side was the finding that possible changes regarding usage requirements and internal loads were more significant than changes as a result of a hypothetical climate change.
