Abstract: A system for regulating a building energy supply and distribution installation, the installation including items of energy collection equipment, each of which is in an energy transfer relationship with a respective source; items of energy transformation equipment powered by the collection equipment; items of energy using equipment; the regulation system configured for defining, for the items of equipment, different respective activation states chosen according to parameters, for optimizing with regard to criteria. The system implements a method in the installation, with the following steps: regulation is performed by placing the items of equipment in respective activation states chosen according to demand and parameters, for the purpose of optimizing with regard to criteria; at an intervention instant of regulation, regulation takes forecasts relating to at least one of the parameters into account, the forecasts relating to a period after the intervention instant.

Abstract: An installation including at least one source of geothermal energy for geothermal storage, at least one other energy source, and equipment for converting and distributing energy. The geothermal source includes probes installed in the medium that permit heat exchange between the geothermal medium and a heat-transport fluid passing through the probes. The method involves defining a forecast trajectory (TP) for the temperature of the geothermal medium over time, evaluating the temperature of the geothermal medium, making an adjustment to the thermal power exchanged between the geothermal medium and the heat-transport fluid which on leaving the probe has a temperature (TW), in the direction of making the temperature of the geothermal medium consistent with the forecast trajectory. The mean (TM) of the forecast trajectory (TP) is stable and preferably exhibits, with respect to the ground temperature (TN) a differential causing an annual thermal flux between the natural ground and the medium.
