Innovative device for the simulation of environmental conditions and testing of building materials
Cacciotti, Riccardo ; Wolf, Benjamin ; Macháček, Michael ; Frankl, Jiří
Excessive humidity influences the performance of building envelopes and the safety of their occupants. Moisture related problems can indeed impose significant health risks for buildings’ users and even lead, under extreme scenarios, to structural failures. This paper investigates an innovative experimental setup for evaluating the influence of changing environmental conditions on the performance of building materials. It stems out from a broader ongoing research aimed at studying the trends of mould growth on wooden building components. The presented results include the design, construction and numerical validation of a small-scale climatic wind tunnel (2m x 1.8m ca.) to be used for the simulation of natural ventilation and daily humidity and temperature fluctuations. Key findings include the final design of a low cost, modular construction which allows gathering reliable data on the response of building materials exposed to changing boundary conditions, intended for improving current mould growth models. Future work is also suggested.

Price comparison of a variant technical solution of a specific building
Zelenay, Šimon ; Mrňová, Zuzana (referee) ; Tichá, Alena (advisor)
The subject of the thesis is a price comparison of a variant technical solution of a specific building. The thesis consists of two parts. The theoretical part describes the basic terms used in the processing of calculation and budget, price theory, types of prices and software used for budget. The practical part consists of the proposal of variable technical solutions and their comparison based on the chosen criteria. The conclusion is the evaluation of various variable technical solutions and the selection of the most suitable technical solution regarding the purpose of the building.

Ecological influences during the construction of a family house
Bortlová, Nicol ; Vaňková, Lucie (referee) ; Kocourková, Gabriela (advisor)
The diploma thesis focuses on the ecological influences in the construction of a family house. The subject is to compare the properties of alternative building materials, determine the cost of building a house and design the optimal way of financing housing for a fictional married couple. Explains basic concepts, namely ecological aspects in construction, project management of buildings, pricing in construction, housing finance. The following practical part compares building materials in terms of their properties and environmental impacts during production, determines the costs of acquisition and operation of a family house and then finds out whether it is possible to finance the construction of the house through a mortgage loan. At the end of the work evaluates what percentage will increase the cost of building a house in the case of the use of materials, the production of which produces less negative emissions. Finally, the optimal variant of housing financing is recommended.

Moisture Measurements
Hřib, Jan ; Pikula, Stanislav (referee) ; Beneš, Petr (advisor)
This bachelor’s thesis deals with measuring moisture in building materials and it is focused on the capacitive and microwave method. The goal was to find out whether it is possible to employ these two methods to determine moisture distribution in the volume of a measured material. This thesis contains theoretical introduction to the moisture measurement. Practical experiments were made with both capacitive and microwave method. Capacitive method was supplemented with a simulation. Based on the results, I conclude that the capacitive method is not suitable to determine moisture distribution in the volume of a material. The same conclusion was reached in the case of the microwave method, although this conclusion was based more on the theory than on the measurements.

Comparation of prices of materials in the country and abroad
Pavlová, Nikola ; Výskala, Miloslav (referee) ; Aigel, Petr (advisor)
The aim of this master’s thesis is comparing prices of building materials wi-thin the building structure in Czech Republic with prices in Poland. The first, theo-retical, part describes differences among the construction classifications and pri-ces. At the end of this theoretical part is written about price calculation of building materials. Specifically about creations of that calculations and comparing between Poland and Czech Republic. The second part is concentrated on created budget and mainly on his bill of materials. The result part is made by comparing of chosen building material pri-ces..

Classification of material used for the construction of garden ponds
Sýkora, Jiří ; Repková, Martina (referee) ; Komendová, Renata (advisor)
This thesis deals with the study of the occurrence forms of inorganic phosphorus in water garden ponds and used material impact on the amount of releasable amount of phosphorus in the form of phosphates in the water medium. The practical part of this work focuses on the analysis and subsequent classification of building materials for the production of garden ponds just by releasing ability of phosphorus in the form of phosphates in the water.

The ruins and the possibilities of their conservation
Pyreňová, Eliška ; Vyšvařil, Martin (referee) ; Rovnaníková, Pavla (advisor)
This bachelor´s thesis deals with a question of conservation of castle ruins. The theoretical part discusses generally building materials used in their construction, sort of material´s degradation and corrosion of materials, possibilities of ruin´s conservation by using suitable building materials, and processes in realization of historical property restoration. Work focuses on a history and conteporary condition of two historical buildings, the castle Cimburk in Czech republic and the castle Lietava in Slovakia. As a part of my work was collection and subsequent analysis of samples of historical mortars of these castle. Resulting response curves differential thermal analysis, RTG diffraction analysis and their mutual comparison.
