Energy reduction can benefit from the improvement of energy efficiency in buildings. For this purpose, simulation models can be used both as diagnostic and prognostic tools, reproducing the behaviour of the real building as accurately as possible. High modelling accuracy can be achieved only through calibration. Two approaches can be adopted-manual or automatic. Manual calibration consists of an iterative trial and error procedure that requires high skill and expertise of the modeler.

For the design of new buildings or buildings undergoing major renovations, the use of building performance simulation (BPS) tools is a key instrument to sizing the envelope or to select the best solution to be integrated. Nowadays, many BPS tools are available and are used by researchers and designers, each of which was independently validated, by considering different operating conditions, and rarely were directly compared in the same conditions.
