Method of predicting the energy consumption of a building

摘要

Disclosed is a method for forecasting the energy consumption of a building, taking into account the heat exchanges from received solar radiation and/or heat convection and/or conduction between the building and the outside environment based on a physical model. The method includes a learning step to deduce the value of the parameters of the physical model based on previous measurements performed on the building.

1. Method for controlling energy consumption of a building, comprising:
forecasting the energy consumption of the building, implemented by a computer and using a physical model taking into account heating and cooling (Pc) of the building by a heating or air-conditioning device, passive solar inputs (Pasp), inputs by internal gains (Pi) including heating from body heat of people and household appliances in the building, and heat losses (heat losses) by heat convection or heat conduction between the building and an outside environment, wherein the forecasting comprises
a learning step to deduce therefrom the value of the parameters of a physical model based on previous measurements performed on the building, the learning step comprising:determining at least one first parameter of the physical model relating to the internal gains and the heat losses based on previous measurements during periods of a first intensity of sunlight;determining at least one second parameter of the physical model relating to the passive solar inputs based on previous measurements during periods of a second intensity of sunlight, the second intensity being greater than the first intensity; andestimating the forecast of energy consumption using the physical model using the first and second parameters; andcontrolling the heating and air-conditioning devices of the building to implement heat regulation of the building based on the forecasting step.
