1. A method for indicating energy savings for a distributed site, the method comprising: receiving, by an energy management system, energy consumption data from a predefined area of the distributed site for a first observation period; defining, by the energy management system, one or more service windows for the distributed site during its operation, wherein each of the one or more service windows comprises one or more unique energy profiles based on a type of the distributed site, at least one energy profile of the one or more unique energy profiles being associated with the pre-defined area; applying, by the energy management system, an energy saving strategy for at least one of the one or more service windows, based on the at least one energy profile associated with the pre-defined area; receiving, by the energy management system, energy consumption data from the predefined area of the distributed site for a second observation period; comparing, by the energy management system, the energy consumption data for the first observation period with corresponding energy consumption data for the second observation period after application of the energy saving strategy to obtain a saving factor; determining, by the energy management system, one or more adjustment factors in the at least one energy profile associated with the pre-defined area based on parameters affecting the at least one energy profile which were not considered during the first observation period; and indicating, by the energy management system, energy savings for the pre-defined area based on the saving factor and the one or more adjustment factors.
