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 of the current research topics at our institute is High Tech or Low Tech? and which of these approaches are best to reach our goals regarding energy efficiency and sustainability. So far there has not been any sound discourse about this research question in the scientific community. Discussions in the architectural discipline are usually of pure stylistically nature. However, in the past years, there seems a consensus amongst architects, both practicing and those undertaking research as well as students, even though with a more emotional rather than intellectual character, towards a preference for a low-tech-approach. This development is likewise fascinating, as well as- in an era with huge technological developments and a dependency on technology in our everyday life somehow worrying. Is this tendency even a direct effect of an ever growing dependency? How come low tech seems in vogue in architecture? Is it a kind of marketing hype for a new genre? Is it because the approach seems to correspond stylistically with the architectural goals? No-one wants a low-tech mobile phone, a low-tech car or computer. Why a low-tech building then? What is a high-tech building? This question is not as easy as it may seem initially. In order to have a reasonable discussion about advantages and disadvantages regarding a high tech and low tech approach respectively, it is important to have a thorough understanding and precise definition about the above mentioned terms. We currently develop a methodology, which allows, based on the extent and the level of technical maturity of the technologies within a building, a rough classification of buildings in the categories high-tech, low-tech and intermediate categories respectively where applicable.
