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...
