Method for controlling and/or regulating room temperature in a building

The present invention relates to a method for controlling and/or regulating room temperature (9r) in a building. The control of the room temperature can be switched between heating, neutral temperature and cooling according to an uncertainty (qg, ub-qg, lb) of the internal and external increase of heat, said uncertainty being determined in the construction phase. The uncertainty is determined by a low foreign heating limit (qg, lb) and a high foreign heating limit (qg, ub). The method can be commonly used to control and/ regulate the temperature in rooms or areas, in particular, in buildings which are cooled and heated by means of the building material, for example, via thermo active component systems.
