Impact of Moisture Buffering Effect in the Calibration of Historical Buildings Energy Models: A Case Study
Building simulation software can provide a reliable prediction of the building environmental response, however, in historical building simulations the uncertainty increases due to the lack of information and the incorrect choice of the numerical model. In this work, the moisture buffering effect is investigated using two different models in EnergyPlus software. The analysis shows that the selection of the moisture buffering calculation method highly affects the simulation results and the set-up of some input variables during the calibration phase. In detail, the use of the Effective Capacitance model could overestimate the effects of the infiltration in terms of mixing ratio, leading to the adoption of a lower value of air change rate for the model validation (about 3 times in the case study analysed). Such phenomena particularly affect historical buildings, generally characterized by massive structures and many furnishings.
