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 Modernization Terrassenhaussiedlung

Prof. Brian Cody, Dipl.-Ing. Alexander Eberl, Dipl.-Ing. Edina Majdanac





The exploratory study Smart Modernization Terraced Housing Estate - SONTE aims at developing a general decision support for the assessment of modernization possibilities of participatively designed existing residential buildings. The Terraced House Estate Graz-St. Peter serves as a development and test field at the same time. The development of the guideline will be demonstrated by the example of the housing estate and extended to other residential buildings. The focus of the work is on a comprehensive, holistic approach that includes ecological and social aspects.


The Terrassenhaussiedlung in Graz-St. Peter is the largest contiguous and internationally best known housing estate in Styria. At the same time it is the largest owner-management unit in Austria with over 500 apartments and more than 1500 inhabitants. After more than 40 years of use of the housing estate, the issue of smart modernisation in terms of an energetic, sustainable orientation is to be assessed. The progressive character in the construction of the terraced house settlement holds a high potential for an integrative modernisation concept. The innovative approach of the participatory involvement of the residents in the further development of social housing is unique so far. Using modern participation methods, the existing resident community is reactivated, networked with important actors and intensively involved in the development of the smart modernisation concept. Thematically, the focus is on buildings and energy, green and open space, urban mobility as well as information and communication as relevant fields of action. This enables the necessary consideration of the settlement as a complete system with regard to the energy, structural and social structure. Through the strong interaction and networking of the individual areas, the optimisation of the individual solutions is achieved.
