Abstract: An appropriately treated flow of air is supplied to a room in an automatically executed pulsed operation, in which the air flow is alternately switched on and switched off. The air flow is switched off independently of the room usage state if the regulated room comfort variables lie within a respectively assigned comfort band. If at least one of the regulated room comfort variables lies outside the comfort band assigned to it, the flow of air minimized in respect of its volume is supplied to the room. This means that ventilators used for the exchange of air will be operated at the lowest possible speed, optimized in respect of time and thereby with high energy efficiency.

Abstract: In a building which has at least two floors, an apparatus for controlling and regulating room temperature having a hierarchical structure includes a predictive device on the top level, that provides optimal control of the use of at least one free energy source, and at least one device on a lower level which is used for feedback regulation of at least one additional energy source. The predictive device uses a building model and repeatedly optimizes the energy requirement or the energy costs. The regulation strategy of the predictive device uses characteristics of a passive heat accumulator of the building.

Abstract: In a method for controlling and regulating at least one room comfort variable (TR1; TR2) in a building, requirement signals (30) for cost-intensive energy are stored during a time interval (73) comprising a specified time period, the requirement signals (30) stored in the elapsed time interval are evaluated and used to generate current control signals (10, 11 . . . 15) for actuators for the use of what is known as free or low-cost energy. The method minimizes the consumption of cost-intensive or what is known as not free energy whilst still satisfying a predefined comfort requirement when heating, cooling, ventilating, lighting and shading rooms or zones of rooms in the building.

Abstract: A method controls and/or regulates room temperature in a building. The control of the room temperature can be switched between heating, neutral temperature and cooling according to an uncertainty 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 and a high foreign heating limit. Said method can be commonly used to control and/or regulate the temperature in rooms or areas, in particular, in buildings, which are cooled and heated by controlling the temperature of the building material, for example, via thermoactive component systems.
