Abstract

Method for managing the energy of a building, comprising one or more occupants likely to be present therein, each determining a comfort desire for a given period, characterized in that it comprises a step for determining an overall comfort parameter for a given period on the basis of the comfort desire of each occupant present in the area of the building in the given period, this global comfort parameter being used to manage the energy on the basis of the comfort desires of the only occupants present in the building.

First claim

The invention claimed is:

1. A method for managing an energy system of a building, comprising one or more occupants to be present in an area (i) of the building, each occupant determining a desired ambient temperature for a given period (k), wherein the method comprises
a step for determining a global thermal comfort criteria including an overall thermal sensation value Si (k) in area (i) for period (k), this value being defined from the desired ambient temperature of each occupant present in the building in the area (i) for period (k), and in that the method comprises a determination of heating or cooling in each area (i) for each period (k) in order to achieve the comfort criteria, based on meteorological forecasts for each period (k), using a thermal behaviour model of each area (i) of the building to link a temperature (T i (k+1)) of an area (i) for a period (k+1) to a temperature (T i (k)) of the area (i) in a preceding period (k), according to thermal constants of the building, of an energy (P m (k)) supplied by an appliance during the period (k), of an outdoor temperature (Text (k)) in the period (k), of solar radiant (Φs (k)) affecting the area (i) for the period (k), by the following equation:
T i ( k+ 1)= A T i ( k )+ B P m ( k )+ C 1 Text( k )+ C 2Φ s ( k )

in which A, B, C1 and C2 are matrices of the thermal behaviour of the building,
a step for determining a binary global occupancy parameter (O i,k ), representing presence or absence of at least one occupant in an area (i) of the building for a given period (k), which takes a zero value when absence and is equal to one when there is at least one occupant, and in that it takes into account a product of the global occupancy parameter (O i,k ) by the global comfort parameter for the management of the energy of the building based on the desired ambient temperature of the at least one occupant present in the area of the building concerned during the period (k), and
adjusting the energy system of the building using the determined global thermal comfort criteria and the determined binary global occupancy parameter (O i,k ).

2. A method for managing an energy system of a building, comprising one or more occupants to be present in an area (i) of the building, each occupant determining a desired ambient temperature for a given period (k), wherein the method comprises
a step for determining a global thermal comfort criteria including an overall thermal sensation value Si (k) in area (i) for period (k), this value being defined from the desired ambient temperature of each occupant present in the building in the area (i) for period (k), and in that the method comprises a determination of heating or cooling in each area (i) for each period (k) in order to achieve the comfort criteria, based on meteorological forecasts for each period (k), using a thermal behaviour model of each area (i) of the building to link a temperature (T i (k+1)) of an area (i) for a period (k+1) to a temperature (T i (k)) of the area (i) in a preceding period (k), according to thermal constants of the building, of an energy (P m (k)) supplied by an appliance during the period (k), of an outdoor temperature (Text (k)) in the period (k), of solar radiant (Φs (k)) affecting the area (i) for the period (k), by the following equation:
T i ( k+ 1)= A T i ( k )+ B P m ( k )+ C 1 Text( k )+ C 2Φ s ( k )

in which A, B, C1 and C2 are matrices of the thermal behaviour of the building,
wherein the step for determining an overall thermal sensation value Si (k) for a given period (k) comprises the determination for each potential occupant (j) of a desired maximum ambient temperature (T max j (k)), of a desired minimum ambient temperature (T min j (k)) and of a desired ideal ambient temperature (T opt j (k)) for each period k, and in that it comprises a calculation of a desired average maximum ambient temperature (T max i (k)), of a desired average minimum ambient temperature (T min i (k)) and of a desired average ideal ambient temperature (T opt i (k)) for each area (i) of the building and for each period (k) according to the following equations:
