  • ABOUT

    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. 

  • ABOUT

    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.

Description

The Institute for Buildings and Energy was commissioned to assess the energy efficiency of the designs of the architectural competition for the new corporate headquarters of the energy supplier STEWEAG-STEG GmbH in Graz. The client decided in favour of a refurbishment of the high-rise building on the Leonhardgürtel, a building from the early 1960s, as part of a restructuring process. In addition, the location will be expanded by 150 people. As a result of the consultation, STEWEAG-STEG GmbH was ultimately able to make a well-founded assessment of various design options regarding energy efficiency and comfort aspects. The evaluation of the designs included, for example, the effects of the location and orientation on the property, the influence of the building shape on the energy balance, an optimal design of the facade and the question of the extent to which natural ventilation is possible. In addition to the energy evaluation of the designs submitted in the architectural competition, various alternative strategies for the refurbishment of the office building were also examined. For many building owners and planners, the breakdown of the energy demand into the individual originators brings surprising findings. This knowledge is in turn a prerequisite for being able to reasonably assess the relevance of individual aspects. One striking aspect of the submitted designs was that the efforts of the planning teams regarding energy improvements concentrated on reducing heat losses in winter by improving the insulation standard. However, the results of dynamic computer simulations have shown in this case that the influence of subsequent thermal insulation of the opaque wall surfaces is of secondary importance with regard to the total primary energy requirement, and that in view of a given available budget, consideration should be given to which strategies can achieve the highest possible benefit at the same cost.
