Heating, Ventilating and Air-Conditioning systems in museums are called to properly control important microclimate parameters, not only for visitors’ wellbeing, but mostly for the preservation of works of art. Accordingly, in case of interruptions to Heating, Ventilating and Air-Conditioning systems, due to maintenance interventions or drawbacks, it is essential to guarantee the acceptable break from service to which possible damages for the works of art are related. In this regard, the aim of this work is to introduce a simple indicator to support curators in regulating the stipulation of contracts with external companies, a more effective management and maintenance of the Heating, Ventilating and Air-Conditioning systems will thus be achieved in order to preserve the works of art, by integrating into the contracts economic penalties related to the system’s service break period. The feasibility of this new procedure has been checked by means of a case study involving the “Museo Regionale” of Palermo (Italy).
