This article deals with the assessment of methodologies for water vapor condensation determination and mold growth risk analysis on the surfaces of an organic building structure based on in-situ monitoring, carried out on the structural elements of renovated roof truss above the greenhouse “Květná zahrada” in Kroměříž. The garden including the building is signed on the UNESCO Word Heritage List for its historical and architectonical value. The monitoring was focused on hygrothermal behavior of a particular attic area during winter term 2014 - 2015. The risks of water vapor condensation and mold growth were then analyzed on the basis of data obtained by the monitoring process. These also include measurement and output data accuracy is included as well. The Results were used as recommendation for a control system of forced ventilation in the monitored attic area.

This paper deals with the determination of linear thermal transmittance for buildings with acute angle shapes. Calculation of linear thermal transmittance is a standard problem in determining the influence of thermal bridges on the overall energy performance of buildings. Computational methods are known for ordinary rectangular buildings and the values of typical detail are listed in databases. Current architecture of designs buildings uses acute angle shapes quite frequently. It corresponds with new trends in architecture. In such cases the value of linear thermal transmittance is not accurate for using databases. This paper presents an analysis of the influence of the change of angle of the walls in corner to linear thermal transmittance. It provides information applicable for buildings assessment in engineering practice.

This paper deals with the determination of linear thermal transmittance for buildings with rounded shapes. Calculation of linear thermal transmittance is a standard problem in determining the influence of thermal bridges on the overall energy performance of buildings. Computational methods are known for ordinary rectangular buildings. Current energy-saving architecture designs buildings with rounded organic shapes quite frequently. Not only it corresponds with new trends in architecture, but also serves to improve the area to volume ratio of buildings. In such cases the value of linear thermal transmittance calculated by standard methods isn't accurate enough. This paper presents an analysis of the influence of the curvature of the buildings surface to linear thermal transmittance. It provides information applicable for buildings assessment in engineering practice.

Renovation processes of existing buildings, including historically protected ones, are most of the time focused on energy saving. Nonetheless these processes might affect the function of existing shallow foundations. This paper deals with the influence of soils moisture content onto the depth of freezing. The depth of freezing depends on the type of soil as well, not just the moisture content. The influence of water and soils composition are generally perceived to be substantial for depth of freezing. Sub-zero temperatures do significantly change the soils characteristics, which has an effect to the building structure. The purpose of the research done by the personnel of Brno University of Technology was to determine the effects of special measures against frost penetration of soil. These measures included the application of various materials and solutions over the terrain in winter to monitor frost depth of soil.
