System for processing data and modelling for analysis of the energy consumption of a site

A non-transitory computer readable medium that stores a program, which when executed by a computer, cause the computer to perform a data processing method for analysis of the energy consumption of at least one site using measurement data, including electrical consumption measurement data and also data for measuring one or more physical parameters, taken from at least one measuring device installed in this site, the method comprising:

• receiving from sensors included in the measuring device, the physical parameters which include at least one of temperature, rate of humidity, differential pressure, and air speed, the physical parameters to generate time series data;
• and
• selecting, within a chosen analysis time range, the time series of data taken from the measuring device, where the time series are associated with metadata which explains the said data time series;
• segmenting the data time series into multiple data segments of identical duration, the multiple data segments including at least types of operational days at the at least one site, including working days, closed days, start-up days, and partial operational days;
• projecting the selected data segments located within this analysis time range in a space having at least two dimensions, according to their degree of similarity;
• displaying in a software graphical interface by means of a display device connected to the computer processing system, a graphical representation of the said space including projections of the data segments, where some projections are grouped together in the form of one or more groups of data segments, such that the data segments are visually clustered based on the type of operational day;
• selecting at least one first group of data segments based on receiving an input from a user in the software graphical interface of a drawn region surrounding a visually displayed cluster of data segments corresponding to one of the types of operational days, wherein the drawn region excludes one or more aberrant data segments corresponding to the one of the types of operational days which are not displayed within the visually displayed cluster of data segments, and deleting the one or more aberrant data segments in the software graphical interface based on receiving an input from the user of a drawn region surrounding the one or more aberrant data segments;
• and
• establishing one or more digital models characterising the first selected group of data segments.
