System for controlling room temperature in a building using a free energy source, an additional energy source, and predictive control
First Claim
1. A system with a control arrangement having a hierarchical structure of at least two hierarchical levels for controlling and regulating room temperature in a building, comprising:
- at least one predictive controller, arranged at an upper hierarchical level of the control arrangement, providing optimum control of use of at least one free energy source or cost effective energy source; and
at least one subordinate controller, arranged at a lower hierarchical level subordinate to the upper hierarchical level of the control arrangement, providing feedback regulation of at least one additional energy source in a zone controlled by the at least one subordinate controller to the at least one predictive controller, whereinsaid at least one predictive controller generates a control signal for said at least one subordinate controller for feedback regulation based on the feedback regulation provided by the subordinate controller, the control signal having information relating to the optimum use of the free energy source or cost effective energy source, andsaid at least one predictive controller uses a building model and has a regulation strategy that utilizes properties of a passive heat accumulator of the building.

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.
