The analysis and the knowledge of the historical building masonries is a key element for preserving and enhancing their heritage value in a conscious way. The paper aims to simulate the hygrothermal behavior of several traditional masonry structures, using a 2D software (Delphin 5.8.3). It is a dynamic simulation program for the coupled heat, moisture, and matter transport in porous building materials. There are many kinds of historical masonries, with different geometries and characteristics. The most important difficulties in the simulation concern: (i) the graphic simplification of complex structures, and (ii) the choice of the materials from the existing databases. In addition, the influence of wall orientation, climate data, and boundary conditions is relevant to the final results. The focus of this paper is the comparison between the hygrothermal simulations and the in situ heat flow meter measurements of some traditional Italian solid walls. In this way, we can understand the influence of different assumptions, parameters, and simplifications on the virtual models.

Abstract
The analysis and the knowledge of the historical building masonries is a key element for preserving and enhancing their heritage value in a conscious way. The paper aims to simulate the hygrothermal behavior of several traditional masonry structures, using a 2D software (Delphin 5.8.3). It is a dynamic simulation program for the coupled heat, moisture, and matter transport in porous building materials. There are many kinds of historical masonries, with different geometries and characteristics. The most important difficulties in the simulation concern: (i) the graphic simplification of complex structures, and (ii) the choice of the materials from the existing databases. In addition, the influence of wall orientation, climate data, and boundary conditions is relevant to the final results. The focus of this paper is the comparison between the hygrothermal simulations and the in situ heat flow meter measurements of some traditional Italian solid walls. In this way, we can understand the influence of different assumptions, parameters, and simplifications on the virtual models.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
