  • 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.

Energy efficient ventilation of office buildings

Prof. Brian Cody

Description

This research project deals with the following questions:

 

- How energy efficient is mechanical ventilation in office buildings compared to normal window ventilation?

 

- Are the planning characteristics of the mechanical ventilation systems commonly used in office buildings today reasonable?

 

- If openable windows are provided in an office building, is additional mechanical ventilation necessary under extreme outdoor air conditions, or how economical or ecological is it to provide such ventilation?

 

- If mechanical ventilation is provided for extreme outside air conditions, how economical or ecological is it to provide additional window ventilation, which may have to be elaborately designed due to wind or noise problems with double facades, automatic control, etc.?

 

- Are there solutions in the form of hybrid systems which combine the advantages of both systems (window ventilation, controlled ventilation) in one system?

 

- Which requirements would have to be met by such a hybrid system and what could such a system look like? It has been shown, among other things, that mechanical ventilation systems with heat recovery, as they are installed in many European countries with the background of energy saving, are often energetically not useful, because the saved heat energy is more than compensated by the additional expenditure of electrical energy. Furthermore, solutions for natural ventilation systems for very high or very low buildings as well as for hybrid systems, which combine the advantages of mechanical and natural ventilation in one system, were discussed.
