In a first step, relevant national and international studies on the topics of low-tech / high-tech and the associated parameters of user comfort and acceptance are reviewed and analysed. The technical subject area of the research primarily concerns the coherent definition of low-tech / high-tech concepts and the "depth of technologisation of the building". At the same time, an evaluation grid is being created, which can be used to assess buildings with low-tech aspects in terms of user comfort and acceptance, taking into account energy requirements and life cycle costs.

The evaluation grid subsequently supports the selection of properties in whose environment empirical surveys are carried out. For this purpose, technical data such as energy requirements in use are collected and interviews are conducted with planners, users, property managers, facility managers and authorities.

The knowledge gained can serve as a basis for the creation of guidelines and for the planning of new buildings and comprehensive revitalisations with low technical effort and high user comfort at the same time.
