  • Institut für Energietechnik der TU Berlin, Fachgebiet Maschinen- und Energieanlagentechnik (zentrale Projektsteuerung)

Description of the project

The ENGITO Project investigates potential methods of saving energy in buildings in Berlin. It is focused on non-residential buildings which are equipped with modern and complex plant technology such as educational facilities, sport complexes, administrative buildings and social facilities.  Research is then conducted to establish which low-investment technological and organisational measures can lead to savings within the areas of heating and cooling plant technology.

The project will be carried out in close cooperation with the Department of Mechanical and Power Plant Engineering (Fachgebiet Maschinen- und Energieanlagentechnik: ETA) at the TU Berlin. The results of previous studies by the ETA show that the implementation of simple energy saving measures in buildings is often impaired by planning and installation errors, but negative organisational circumstances also constitute a factor.

The task of the social science subproject at ZTG is to identify these institutional and individual obstacles such as knowledge deficits, unclear responsibility structures or diverging interests of the actors involved and to develop optimisation measures. The study includes extensive empirical surveys from approx. 35 properties. As part of the research, inspections, qualitative individual interviews with actors from different target groups, quantitative surveys as well as focus group discussions and workshops with practitioners are planned.


The ENGITO Project will attempt to answer the following questions:

  • How can the potential savings of technical measures be identified and quantified in complex heating and cooling systems?
  • Which factors have an inhibitory influence on the energy-efficient operation of complex systems?
  • Which low-investment potential savings exist in the complex facilities of non-residential buildings in Berlin?
  • How are technical and organisational measures related in the respective organisational context and which combination of measures is suitable in each case?
  • How can knowledge about such complex plants be secured and made available to the relevant actors?


The results of these investigations are to be discussed against the background of technical and organisational sociological theories. Key findings from these discussions will then be used to construct approaches to socio-technical systems and constellational analysis.

Measures which have been identified early in the project are planned to be put into practice during the project runtime in order to bring about savings for the participating buildings.
