  • 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.

Double Skin Building Envelopes and their impact on the HVAC Systems and energy efficiency of Buildings

INFO

PHOTOS

Description

Case studies were used to investigate the effect of double facades on the planning and dimensioning of building services systems and on the overall energy efficiency of buildings. The main result of these investigations was the finding that the energy efficiency of buildings with double facades depends on whether the use of the double facade makes it possible to dispense with entire building services systems (e.g. mechanical ventilation). If this is not the case, it can take up to 25 years until the additional manufacturing energy expenditure of the second skin is compensated by energy savings during operation. If, on the other hand, a complete technical building system can be omitted due to the double facade, this energy payback time is reduced to a reasonable period of time, in some cases even within 2 years. The case studies examined clearly show that highly efficient double facades can not only improve the energy performance of the building but can also significantly reduce the investment costs of the building services. Therefore, the cost-effectiveness of such a measure should not only be evaluated in terms of its potential for reducing energy costs, but always in connection with a possible reduction of investment costs for HVAC systems in the building. A mere reduction in the size of the building services systems usually does not lead to significant savings.
