A comprehensive technical economic analysis of an electric car and a hydrogen vehicle
Lašák, Ondřej ; Sitek, Tomáš (referee) ; Elbl, Patrik (advisor)
Modern human society has undergone rapid technological development, and, as a result, humanity has begun to change the climate of planet Earth. The result is rising average temperature across the planet and some areas are threatened to become uninhabitable. One of the causes of global warming is the high CO2 emissions arising, among other things, from transportation. That is why transport is being diverted from fossil fuels to alternative energy carriers such as hydrogen or to direct usage of electricity. The aim of this work is to compare a hydrogen car and a battery electric car in terms of emission and energy requirements. In the last part, the economic costs of the transformation of passenger transport to these new fuels are approximated. The comparison includes current conditions and outlook to the future.

A proposal of production technology of a holder
Stará, Veronika ; Zemčík, Oskar (referee) ; Sliwková, Petra (advisor)
The bachelor's thesis deals with the analysis of the current production technology of the specified holder. The new design of the production process deals with the selection of the CNC milling center, the selection of suitable tools for machining, the selection of cutting conditions and determining the length of production of individual operations. The work includes an economic comparison of both variants of the production process.

Administrative grounds in Prague - Hostivař, preparation and organization of building construction
Smolková, Pavlína ; Mohapl, Martin (referee) ; Šlanhof, Jiří (advisor)
Final work is processed for an administrative center in Prague. It is the preparation and organization of the construction of the object in Hostivař. The work is done for the most important technological phases of site equipment, economic comparison of cranes, financial and time evaluation of building, selection of main mechanisms and main part of the text dealing with the character of the building, its technical data, process of constructing the object and the overall treatise about building. Technological process is made for the technological phase of construction of assembled skeleton.

Economic comparison of light sources
Růžička, Josef ; Motyčka, Martin (referee) ; Štěpánek, Jaroslav (advisor)
This bachelor thesis deals with the economic comparison of light sources. On the market there is currently no physical quantity that would enable the light sources to be compared from an economic point of view in long-term perspective. The main objective of the work is, therefore, by calculations of the specified (or directly measured) parameters of the light source to provide a uniform total cost of lighting, thanks to which it will then be possible to sort the sources according to the price benefit. Evaluation is based on measurements of 28 light sources from different groups: the classical bulbs, halogen bulbs, compact fluorescent bulbs, compact LED retrofits and dimmable LED retrofits with color-changeable modes. These light sources are meant to be used for indoor home lighting, offices, halls, etc. The final part of the paper clarifies what kind of light sources and for what reasons they are the most profitable and have the greatest potential for the future. There's also a comparison of theoretical parameters provided by the manufacturer, and parameters directly measured in the laboratory and the evaluation of the deviations between them. The use of this thesis comes from provision of the calculation structure to a user who will better understand the topic of costs while purchasing the light source. Well arranged description and information about the light sources in theoretical part of the thesis is another utility to be mentioned.

Implementation of the gross superstructure of residential house in Boskovice
Přikryl, Jan ; Kučera, Zdeněk (referee) ; Kantová, Radka (advisor)
The bachelor thesis deals with the realization of the upper gross construction of the apartment house in Boskovice. The content of the thesis is the technological regulations for vertical and horizontal constructions, a detailed schedule and an itemized budget. Due to its great demands on quality of building construction and safety during building itself there are included chapters dealing with this issue in the thesis. The thesis also contains a technical report of the construction site including its technical drawing. The chapter that deals with different assignment is drawn up alternative design of outside cladding of the building. It consists of two variants: with or without thermal insulation. This is a price comparison and a comparison of the heat transfer by individual constructions. The draft is complemented by relevant details.

Implementation of the gross overhead construction of the Jemnice residential building
Pozler, Tomáš ; Kolečkářová, Barbara (referee) ; Kantová, Radka (advisor)
The bachelor thesis deals with the implementation of the gross overhead construction of the Jemnice residential building. The content of the thesis is the technological regulations for masonry and monolithic construction. It is complemented by a layout of used machinery, all material transport, a measurement report, a detailed timetable and a budget. The chapters dealing with the great demands on the quality of the building project and the safety during its construction are included in the thesis. There is technical report of the construction site equipment, including its drawing. An alternative design of the outline shell with thermal insulation is in a separate chapter. It compares the differences between price and time, complemented with a measurement report. The proposal is supported by relevant details.

Heating Technologies for Household Heating
Krakovič, Vojtěch ; Elbl, Patrik (referee) ; Lisý, Martin (advisor)
This bachelor's thesis presents and compares the current options for heating family houses. The first part introduces the available heating technologies and types of fuels, explains the principle of their operation, shows the advantages and disadvantages, and for which type of building each type is suitable. It will gradually introduce heating with solid fuels, gas and electricity, and continue to heat pumps and methods of obtaining solar energy. The second part introduces a model house for which a suitable heating method is being sought. Heat losses and annual heat demand are calculated. After a short discussion of suitable alternatives, two suitable options are chosen, for which the approximate initial and operating costs, as well as payback periods, are calculated. The following is a comparison and evaluation, after which we will find out the most economically suitable heating method for the model house.
