Patent ID: 8909482

Claim:
A device for measuring power consumption and performance with respect to the environment of a power-consuming unit comprising a data introduction module, which receives at least one power consumption value, measured by a measurement apparatus of the power-consuming unit; an input device for inputting waste production data; a display screen; and a computer with a processor and a memory device having therein a plurality of instructions that, when executed by the processor, cause the processor to (a) receive the at least one power consumption value from the data introduction module, (b) receive the waste production data, (c) calculate an ecological parameter based on the at least one power consumption value and the waste production data, and (d) operate the display screen to display the calculated ecological parameter, wherein the calculated ecological parameter is an adjusted mean of the sum of the deviations of the at least one power consumption value with respect to a reference value corresponding to the at least one power consumption value.
