A general model for energy efficiency calculation

The paper presents a general model for energy efficiency calculation, developed with the main purpose of being capable to deal with the fast changes our society faces nowadays. After any energy saving activity, either technological or even behavioral, the model will be able to estimate the energy, which would have been consumed under the supposition that the aforementioned activity was not implemented. Then, based on the energy measurements, it will calculate the total energy saving. The methodology applied is analyzed, and some preliminary results are discussed.
