Computer-implemented method for energy efficiency management of an industrial plant

Computer-implemented method (1) for energy efficiency management of an industrial plant, characterized by the fact that it comprises at least the following steps:

• starting from a plurality of files relating to data sheets of industrial appliances, a step (2) of extraction of the image files of graphs (G) containing curves (C) describing the technical characteristics of the industrial appliances;
• a step (3) of determination of the characteristic equations of said curves (C), defined in the specific Cartesian space of each graph, starting from said image files of graphs (G);
• a step (8) of calculating the energy consumption of each industrial appliance by means of said determined characteristic equations;
• a step (9) of comparing the calculated energy consumption of each of the industrial appliances with the energy consumption of at least one industrial appliance in an existing industrial plant:
• if the energy consumption of the industrial plant can be reduced (step 10), or if, the energy consumption being the same, the efficiency of the industrial plant can be improved, then a step (11) is carried out of generation of an alert and of a report comprising the suggested changes to the industrial appliance used in the industrial plant.
