This diploma thesis deals with the impact of thermal insulation on expenses relateted to the operation of the weekend house. Theoretical part describes options of thermal insulation systems, insulation methodes, describes structural prices and costs. Practical part of this thesis describes heat costs on specific weekend house situated in Karlovy Vary region. Thermal insulations are designed in three different variants. Calculation of costs of every designed insulation systém is included in this thesis. In next part of thesis is calculated return of investment for every designed solution. In conclusion of the diploma thesis are compared impacts of thermal insulation on expenses ralated to the operation of the weekend house.

The master's thesis deals with actual possibilities of acquisition water from air humidity in order to obtain fresh water, focusing on energy intensity of vapor-compression refrigeration for it is production. There is a basic determine study for Czech climatic zone in selected localities. For graded cooling capacity dependencies describing the acquisition of water from the air, where is the energy intensity ranges on average between 0,3 ÷ 0,5 kWh/l. For the selected family house are set the individual variants of non-potable rainwater management.

The thesis summarizes general and up-to-date knowledge of descaling during the continuous production of the hot-rolled steel and proposes further streamlining of this process in industrial production. The first chapter of the thesis deals with the origin, structure and physical properties of the scales. The second chapter describes the principles of descaling by using a high pressure flat water jet. The third chapter introduces the principles of the experimental methods and describes the used laboratory equipment. The fourth chapter summarizes the description of the particular experiments and their evaluation, and thus represents the focus of the dissertation. It is divided into six sections which independently solve predefined objectives of the dissertation. The first section focuses on the height and structure development of the scales on 54SiCr6 and HDT580X steels. It has been proven that the height of the formed scales increases with the time and temperature of the oxidation. The layered nature of the scales was verified at the same time. The second section examines the effect of the nozzle stabilizer on the focussing and distribution of the impact pressure of the nozzle. Experiments have shown that increase of 11 % of an average maximum nozzle pressure can be achieved, depending on the type of nozzle and the length of the stabilizer. The third section deals with the analysis of shadowgraphy images of water jet structures of the nozzles. A script was developed for analysis of these shadowgraphy photos by an adaptive thresholding. The findings are correlated using a regression analysis with an average heat transfer coefficient. It has been reported that most of the standard nozzle configurations produced disintegrated stream of little droplets at the height of the rolled surface. The fourth section focuses on the area of water jet overlap, especially the area of the so-called washout, where the impact pressure of one nozzle is reduced by the nozzle stream of the other. The influence of the pressure change and the mutual displacement of the nozzles is investigated. The analysis showed that the change of pressure did not have any effect on the percentage of reduction of the impact pressure in the area of the washout. It has been shown that if the area of the washout is wide the descaling efficiency in this area may be reduced. The fifth section builds on the previous section and focuses directly on the areas of waterjet overlaps. The influence of the change of rotation and pitch of the nozzles is studied. Experiments have shown that small changes in nozzle pitch do not have a significant impact on impact pressure and heat transfer coefficient. The effect of nozzle rotation, on the other hand, was a significant factor for the efficiency and homogeneity of the descaling of the surface. The last section deals with the effect of the rolling speed on the heat transfer coefficient in the descaling process. The regression model has shown that with a higher rolling speed there is a reduction in the average heat transfer coefficient. Conclusion summarizes the results of the dissertation and proposes which findings can be used in the industry to make the descaling process more effective.

The aim of the thesis is the economic evaluation of return of the different variants of thermal insulation for residential building in Slavičín. In the first part are described the topics, which is related to the issue. Further, it is written the entire range of insulations, which currently are appear on the domestic market. In the practical part is described the residential house and are performed by the proposals of the variants of thermal insulation. Further, they are processed energy performance certificates for buildings, the cost to implement the options chosen. In conclusion, the evaluated individual variants and determined their economic return.

In diploma thesis is elaborated project documentation for the construction of an building of kindergarten. The building is situated in peryphery of Jihlava city. The building is two-storey kindergarten building with a basement. There aure two classes for children 3 - 6 years old in the building. In diploma thesis is elaborated architect-building solutions, building – construction solutions, fire safety solutions and physics qualities of constructions.

Master´s thesis solves problematic of energy evaluation of residential building in Kyjov. The theoretical part analyzes the legislative requirements, the practical part includes energy audit of brick residential building with 9 apartments for 18 inhabitants.

The aim of this thesis is to develop a new building – a cultural and educational center, located in the town of Uherské Hradiště. The building is fitted to the central part of the city, on unused building lot, with good access to public transport links. The building is designed as a partial basement facility, with three floors and a basement. Structurally it is a column-based, skeletal support system, made of reinforced concrete. The basement part consists of bearing walls of reinforced concrete. The ceiling structure is made of locally backed, cross-reinforced slabs, also made of reinforced concrete. The outer perimeter infill masonry is constructed of ceramic bricks with a thickness of 300mm. Interior bearing walls are made of reinforced concrete of appropriate dimensions. Dividing walls are made of plasterboard constructions. Roof structures are formed by a system of flat roofs and terraces. In principle there are two types – the roofs with safety waterproofing and the ones without it. The base structure consists of footings and strips of reinforced concrete.

The main objective of the master’s thesis is elaboration of energy audit within the theme of energy rating of buildings. Work consists of the beginning to the given theme including the actual legislative regulations. Another part is elaboration of the energy audit of building municipality with design and rating the measures of reduction of energy consumptions. In experimental part work deals with evaluation of building thermal envelope with use of thermograph measurement, also with quality of indoor environment within the use of building by measurement of concentration of CO2 and with heat and humidity balance.

Contain of master´s thesis is a energy assessment of multifunctional building in Komňátka. The theoretical part deals with the analysis of legislativ documents, current technical solution and practical application to the specified building. In the practical part thesis focus on experimental determination of the heat transfer coefficient using thermography.
