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.

Abstract: A predictive apparatus for controlling or regulating supply values (T_VRL) includes a first data store in which rules, based on a linear consumer model, for calculating process values are stored, a second data store in which rules for restrictions or limit values to be observed for process values and for values derived from process values are stored, and further also means for repeatable optimizing of the energy consumption or of the energy costs with the aid of linear or quadratic programming. The apparatus is configured such that the optimizing can be carried out over a sliding time horizon.

Abstract: A circuit and method for iteratively estimating Fourier coefficients of one or more Fourier components of a measuring signal utilizes a filter to determine the Fourier coefficients for sampling time k-1. The coefficients are utilized to obtain an estimate of the measuring signal at sampling time k. A subtractor circuit subtracts an actual sample of the measuring signal at sampling time k from the estimate of the measuring signal at sampling time k to obtain a difference signal. The difference signal is inputted back into the filter to determine an estimate of the Fourier coefficients at sampling time k.
