Capacitance Measurement of Building Materials
Skalský, Ondřej ; Beneš, Petr
This paper presents the basic principles of nondestructive indirect moisture measurement of masonry from dielectric property analysis. For the selected parallel plate method, three methods that have been experimentally tested are presented. The aim of the work is to provide a comprehensive body of theoretical information complemented by an unambiguous procedure supported by experiments for the measurement of permittivity of building materials at different humidities and temperatures, which will serve as a basis for subsequent experimental acquisition of the moisture and temperature dependence of permittivity for selected building materials. The purpose of obtaining these characteristics is to develop and calibrate a low-cost embedded prototype system for continuous moisture measurement of building materials.

Mortars with Alternative Materials
Kozielová, Silvie ; Sokola, Lubomír (referee) ; Žižková, Nikol (advisor)
This bachelor’s thesis deals with building material mortar. These are mainly the use of waste materials from industry to replace part of the filler or binder to produce mortar. The theoretical part deals with information about the classification and properties of mortar on their ingredients and methods of use. Collectively describes alternative raw materials suitable for use in mortar production and trends of our time for its production. The practical part is focused precisely on the use of alternative raw materials to replace part of the filler or binder to produce mortar. Evaluated and compared with the properties achieved by the mortar with the selected raw materials waste.

Diagnostics and proposal to eliminate thermal bridges buildings
Bravenec, David ; Janík, Zdeněk (referee) ; Kalousek, Miloš (advisor)
This thesis presents a comparison of building materials for vertical bearing structures of buildings, thermal insulation materials and mutual combination of structural materials and insulators. Furthermore, there are possibilities for solving the most common insulation thermal bridges construction. The paper evaluated the pros and cons of different combinations of building materials. Teplo and Area programs were used for the calculations.

Pravcová, Tereza ; Roudná, Veronika (referee) ; Tichá, Alena (advisor)
The bachelor thesis deals with the budgeting of water main and gravity sewer system. The theoretical part provides basic information related to the price. Historical development of pricing in construction, basic concepts and regulations. In next part there are described costs in budgeting, types of budgets and basic characteristics of water management structures. The practical part deals with the revaluation of budgets and the creation of an analysis of the development of prices of building materials and works of water management structures.

Possibilities of utilizing waste from the production of cement-bonded particleboards in building materials
Bartoň, Andrej ; Vacula, Miroslav (referee) ; Bydžovský, Jiří (advisor)
This bachelor thesis deals with possible applications of waste created during cement-bonded particleboard in building materials production. The theoretical part of the thesis analyzes the individual components and processes in the production of cement-bonded particleboard, production processes during which the waste is produced, and the form and quantity the waste can be found in. The theoretical part focuses on the treatment of the various waste forms and their further use in modified or untreated form. In the practical part, the influence of the binder parts substitution on the cement matrix properties is verified. Fine loose waste from the cement-bonded particleboard was used for the sample production.

Computational structural assessment of buildings in terms of energy performance
Kaplan, Václav ; TROJAN,, Karel (referee) ; Šťastník, Stanislav (advisor)
This thesis deals with the computational comparison of the energy performance of buildings of various construction materials. The work aims at assessing the building as a thermal system. The theoretical part describes the methods for calculating the energy performance of buildings. The experimental part of the work focuses on quantifying the heat consumption of specific buildings in terms of thermal stability and it is later compared with the results calculated in accordance with the applicable technical standards.

Computational Model and Analysis of Energy-Aware Buildings
Kaleta, Radoslav ; Šimek, Václav (referee) ; Strnadel, Josef (advisor)
The thesis deals with the analysis of the properties of the external and internal environment of the buildings, the possibilities of heating and cooling. The emphasis is mainly on the energy intensity and the impact of weather conditions on the building temperature during the year. The model created by UPPAAL SMC describes the behavior of heating and cooling during the year and identifies the energy demand of the given building. The building model itself can be partially modified using the built-in user interface.

Acquisition and operating costs of a selected building
Janků, Tereza ; Labudek, Lukáš (referee) ; Tichá, Alena (advisor)
This Diploma Thesis is focused on initial and operating costs. At first we calculated price for all building and for its other parts, which was calculated by program used for budgeting. After that we calculated partial costs which were done only for specific parts of the construction. These parts were changed and due to these changes we were finding out differences in heat losses and initial costs. Than for individual rooms we were defining heat losses. In this rooms, radiators were designed to cover its heat losses. By summarization of all heat gains we find out boiler´s power and this boiler was used in our building. After that we calculated initial costs for heating system includes radiators and boiler. In the end we compared both kinds of heating systems due to one year operating costs. Results were used for defining final heating system which is the most economic efficiential.

Influence of humidity changes to properties of building materials with organic filler
Vasas, Silvestr ; Vacula, Miroslav (referee) ; Bydžovský, Jiří (advisor)
The bachelor's thesis deals with the issue of dimensional changes of building materials containing organic filler, in connection with changes in the humidity of the environment in which the material is located. Searches of knowledge, especially from the scientific literature showed a significant effect of moisture on volume and weight changes of both wood itself and wood of cement composites. In this respect, the treatment of wood (thermal, chemical, etc.) ort he surface treatment of the final wood of the cement composite (coating systém, impregnation, etc.) is essential to reduce the rate of change due to ambient humidity. Experimental laboratory assessment of dimensional and mass changes proved compliance with theoretical knowledge and extended them by specifying the effect on individual dimensions. The different behavior of cement-bonded particleboards in terms of their hygroskopicity was demonstrated on the changes of the boards surface threatment with the coating system and on the boards without surface threatment.
