“…For instance, the VTT model (Hukka and Viitanen, 1999), Sedlbauer’s isopleths (Krus and Sedlbauer, 2002; Sedlbauer, 2001), Sedlbauer’s biohygrothermal model (Sedlbauer, 2001; Sedlbauer and Martin, 2003) and so on are frequently used in mould risk assessments performed in the building physics area (e.g. Abuku et al, 2009; Karagiozis and Salonvaara, 2001; Krus et al, 2007; Langmans and Roels, 2015). These models include the main influencing factors for mould growth: the surface temperature and the relative humidity (RH).…”

To assess the mould risk on materials, different mould prediction models are available. However, each of these models struggles with shortcomings, which might result in widely varying conclusions. A view on the challenges might come in use when developing novel or upgraded models in view of a more reliable risk assessment. Additionally, this knowledge will stimulate a more thoughtful use of the current models. This article shows a preliminary evaluation of some mould prediction models, and this based on experimental literature data on wood. Although experiments are the input for the model development, discrepancies are observed. Therefore, the difficulties and challenges in experimental mould research are discussed.

“…Standard test methodology, ASTM E96, is widely used to accurately capture the average vapour permeability of most materials under typical conditions (ASTM, 2010). Karagiozis and Salonvaara (2001) note that at very high relative humidities, hysteresis effects may alter the average vapour permeability as compared to dry conditions; quantitative hygrothermal analysis is challenging under very high RH conditions for this reason (Peuhkuri, 2003).…”

As consciousness grows regarding the negative impacts most buildings have on the Earth's environment, techniques to mitigate this impact must emerge in mainstream design practices. A calibrated hygrothermal simulation was conducted using WUFI® Pro to assess predicted hygrothermal performance of a variety of wall assemblies that are likely to enter into mainstream design practices. The results of these simulations reveal the importance of designing assemblies that are resilient to field conditions that introduce more severe hygrothermal loads than standard vapour diffusion. It is clear that in order for a wall assembly to perform adequately under moisture ingress conditions, it must be able to dry freely to at least one side of the building enclosure. High-RSI assemblies with exterior XPS exhibited far diminished resiliency to driving rain penetration as compared to those without exterior insulation and those with exterior mineral wool.

Kruja is a middle range city located in the center of Albania. The city of Kruja dates back to its existence from the V-VI century and extends to the city around the VI and IX centuries. It becomes the first capital of Albania in the XI-th century, specifically in 1190. This paper is going to deal with only two groups of buildings which are an integral part of the historical city of Kruja, the historical dwellings (XVIII century) and socialist ones (1960-1970).The aim of this paper is to analyze through linear regressions the relation between two parameters: moisture level and temperature of the indoor walls and floors of the historic and socialist buildings in the city of Kruja. Three types of historic dwelling and three types of socialist apartments have been analyzed, relatively uniformly oriented. The measurements with specific instruments are done in the same day, during three hours. The degree of reactivity is different for both groups of buildings. The historical buildings are more sensitive to temperature rise. They respond invers to it (as the temperature rise, the level of the moisture decreases), with a higher coefficient than socialist ones and appear to be more efficient in reducing the moisture level, despite the average humidity level is higher. This paper takes into consideration also the analyze of the materials of the construction for both categories. If the level of the moisture is reduced, the buildings will be improved and the quality of life indicators of the inhabitance will be improved too.
