1. A computer-implemented method of monitoring and controlling an HVAC system which comprises one or more fluid transportation systems with a plurality of parallel zones in each of the fluid transportation systems, the method comprising one or more processors of a computer system performing the steps of:
receiving via a communication network from a plurality of devices of the HVAC system a plurality of operating variables of the fluid transportation systems;
determining for each of the operating variables a temporal course of the respective operating variable from a plurality of recorded data values received over time for the respective operating variable;
detecting from the temporal courses of the operating variables interdependencies between the temporal courses of the operating variables, the interdependencies including correlations of the temporal courses of the operating variables, synchronicity in changes of the operating variables in the temporal courses, and synchronicity in changes and correlations of the operating variables in time-shifted temporal courses of the operating variables;
grouping the operating variables and their associated devices into different sets, depending on the interdependencies, each set being related to a different section of the HVAC system and including the operating variables and their associated devices related to the different section of the HVAC system; and
using the sets to control the HVAC system to heat, ventilate, air condition and/or cool one or more buildings by controlling devices of a particular section of the HVAC system, using the operating variables related to the particular section of the HVAC system, using the operating variables associated with the one or more devices of the particular section of the HVAC system.
