“…One of the advantages of this model is its ability to numerically capture the stochastic nature of mold growth using the deterministic algorithm. More data are required to test the DR SIM model in a comparison of more widely used classical models like MRD (Mold Resistance Design) or VTT models [18]. There is a wide availability of hygrothermal models in scientific communities where the moisture-related effects become non-negligible.…”

The necessity of understanding and simulating hydrological phenomena as well as their interactions and the effect of anthropogenic and climate conditions on the ecosystem have encouraged researchers for years to investigate the moisture transfer in soil. Considering the moisture transfer as an isothermal phenomenon might cause a wrong estimation due to the non-isothermal nature of the moisture movement in porous media. Hygrothermal (coupled heat and moisture transfer) models are quite diverse and are the engine of the various hygrothermal software tools used to analyze the heat and moisture in building envelopes, drying technologies, and many other applications. This paper is a literature survey conducted to provide an overview on the classical hygrothermal models to address the historical perspectives on these models. First, it investigated, from a historical point of view, the challenges behind the development of hygrothermal models as unsaturated flow theories, beginning with Buckingham theory. The non-isothermal nature of moisture was the starting point for researchers to deal with new challenges during mathematical modeling and experimental analysis. In general, the theory of coupled heat and moisture transfer first developed by J.R. Philip and De Vries and the authors in the mid-1950s inspired the novel hygrothermal models, including Sophocleous and Milly’s model, Rode’s model, Künzel’s model, and Grunewal’s model. In a parallel of hygrothermal model developments, the models of Whitaker and Luikov can also be classified as hygrothermal models; they were mostly applied in modeling the phenomenon of drying. The study highlights the application of hygrothermal models in building physics and gathered a summary of international efforts such as Annex 24, Annex 41, and the HAMSTAD project and advancements performed from the classical dew point or steady-state Glaser method. Moreover, this study emphasizes the advantages of the standard of EN 15026 and limitations of the Glaser method. To sum up, hygrothermal models are still under development based on various assumptions of moisture driving potentials and transfer coefficients.

Many regions of the world have traditional dwellings, which not only represent the main form of residential architecture, but also carry the local vernacular culture, display the region’s unique architectural style, materials and technology, and have important historical and cultural value. Due to environmental factors, traditional dwellings often suffer from architectural damage that threatens the stability of their structure and affects their esthetics value, resulting in a significant number of abandoned and demolished houses. In order to scientifically and effectively solve the damage problems of traditional dwellings, based on the theory of architectural pathology, the following diagnostic method for damage manifestation and the characteristics of traditional houses is proposed: “Architectural Pathology Appraisal–Pathological Environment Analysis–Mechanical Properties Testings”. The traditional dwellings in the ancient city of Guangfu were used as a case study for the practical application of the methodology for analyzing the main types and causes of the damage of the dwellings by examining the damage information of the dwellings, collecting the environmental data of the damaged walls, and testing the mechanical properties of the damaged walls. The results show that the main damage type in the ancient city dwellings of Guangfu is dampness damage, with corrosion deterioration, wall alkali flooding, and the moisture infiltration phenomenon as the manifested symptoms, and the damage is mainly concentrated in the lower part of the wall. In addition, the humidity and moisture content in the lower part of the wall is higher than that in the upper part of the wall, and the compressive strength of the damaged part of the wall is lower than that of the undamaged part. The humid environment of the old town contributed significantly to the destruction of the dwellings, and water intrusion led to a reduction in the strength of the dwellings’ bricks. Through the diagnostic method of building pathology, the causes of Guangfu dwellings’ damage are identified, and scientific and targeted damage intervention suggestions are made. This is expected to provide guidance for the treatment and prevention of building pathology in the ancient city of Guangfu and serve as a reference for the diagnosis and treatment of pathology in traditional dwellings in other areas.
