The paper describes the results of a research activity relevant to automatic management of electrical loads. A commercial/tertiary installation is considered; absence of electric energy from the network and from conventional source is supposed, being electric energy produced from a photovoltaic system. The intrinsically random nature of generated electric energy – eventually less than the requested energy - implies the need to select the loads that can be fed. The Authors built a software named Smart Building Manager (SBuM) that implements the proposed algorithm as a whole. The software is equipped with the mathematical models of electric energy production from PV system. A case study shows the algorithm performance.
