Simulation of solar cells using
Frydrych, Michal ; Vaněk, Jiří (referee) ; Jandová, Kristýna (advisor)
This thesis deals with problems of production of an electric energy by the help of photovoltaic panels. There is mentioned an analysis of problems at calculation of solar system for “island” operation of house, description of all partial segments needed for photovoltaic system and analysis of final costs on purchase of this system. A point of this thesis was making a model of house which used the photovoltaic panels for its function. On this created model was made a measuration during a common day at laboratory conditions and determination the important parameters of solar panel.

Baugruppe Now
Šťastná, Anna ; Císler, Ondřej (referee) ; Hora, Jan (advisor)
Baugruppe, as an alternative option for housing, is made up of a group of people who are looking for a way to create their own housing according to their ideas. They become developers themselves, looking for interesting solutions for their housing that the regular real estate market does not offer. Together, they find land that is often less attractive to ordinary developers and compromise to decide on all the design steps. For the proposed Baugruppe, the site is situated in the town Znojmo, Czech republic. The plots were chosen in such a way that they did not have any particular qualities - on the contrary, that they were rather places that were not at first sight very attractive. The theme of the work is to portray the Baugruppe way of living as community housing. The proposal seeks to figure out a way to make community coexistence as natural as possible for all Baugruppe participants. Whether just meeting the neighbors on the way to their apartments, meeting on the terrace with a friend from the opposite apartment or organizing an event in the common interior/exterior spaces for all Baugruppe participants. All these spaces create a slightly different atmosphere and become a combination of different small worlds that intertwine with each other. At the same time, the aim of the work is to create a house that opens up to its surroundings while allowing all the events of the house to take place undisturbed inside.

Solid Particle Emissions from AgroPellets Combustion
Svoboda, Marek ; Milčák, Pavel (referee) ; Lisý, Martin (advisor)
This thesis is divided into two parts. The first part deals with defining the main concepts, properties of biomass and pellets. Further, the procedures for measuring agropellets properties according to valid standards are mentioned. The following is a selection of the raw materials for the production of agropellet, with the determination of their properties. The theoretical part closes background research emissions from combustion and emission standards for a solid fuel boiler. The second part is an experimental one, which determines the formation of solid pollutants in combustion of four types of pellets made from alternative sources. Here are the graphs of the gaseous emissions of each of them. At last there will be a comparison of emissions agro pellets with more widespread wood pellets.

Comparison of properties of alternative pellets
Jansa, Oldřich ; Moskalík, Jiří (referee) ; Baláš, Marek (advisor)
This thesis deals with the alternative pellets and the means of production from raw material to final customer. The theoretical part deals with different techniques and manufacturing technologies used. Furthermore, the work deals with Czech and European legislation in the field of fuel pellets. The practical part deals with measuring and comparing the properties of selected standard pellets.

Suggestion of a Financial Concept for the Development of a House
Šimek, Pavel ; Pelc, Jiří (referee) ; Škapa, Stanislav (advisor)
The diploma thesis analyzes available methods of financing of a new housing construction with the focus on the possibilities of concurrent investment. The above analysis is demonstrated in a model case study. Practical part contents selection of the products to be analyzed from each evaluated field: suitable mortgage loan, finance market investment, the investment to the alternate heating equipment of the home and photovoltaic power plant. Than demonstrate the possibilities of decreasing the price of the loan with the assistance of concurrent investment into the financial markets or the alternative investment. The risk of investing has been taken into consideration as well. At the end are demonstrated comparative analysis and evaluation of all financing possibilities resulting in suggesting the most suitable method of home loan financing.

The Stirling Thermodynamic Cycle
Macháček, Jan ; Sokanský, Karel (referee) ; Kyncl, Jan (referee) ; Gregor, Jan (advisor)
My doctoral thesis deals with study and analyse of Stirling thermodynamical cycle. Cycle that is composed of two isochoras and two isotherms. I describe functional principle of Stirling engine and all its parts, constructional variations of pistons system and possible engine working modes. Next chapter contains analyse of engine constructional parameters. Measuring of torque and load characteristics, p - V schemes and output work for various engine inputs is part of this analyse. There is composed mathematical engine characterization by means of Schmidt theory in chapter five. Mathematical characterization is consequently applied to engine model. Theoretical analysis and practical measurement were base for concepts, realization and verification of constructional correction. One part of my thesis is attended to design of new lamella for regenerative exchanger. For optimal lamella constructional proportions were used computational algorithm and simulations. There is concept of cogeneration unit with Stirling engine and its benefits check in last chapter. General theoretical and practical analyse of workable Stirling engine is result of my thesis. Analyse in this extent was not nowhere publishing yet. Design of regenerative exchanger lamella is then practical input of my thesis.

Wind power station tower - calculation
Stein, Pavel ; Vrbka, Martin (referee) ; Nevrlý, Josef (advisor)
The target of this labour is to give summary of contemporary level of construction of wind power station tower. The first part describes importance and progress of alternative sources of energy, especially wind energetic in Czech republic. Next point concerns some construct options of wind power station tower and its basic elements. Close of the work is oriented to modern forms in problems of the wind power station tower and indicates options of modern development.

Environment-Friendly Housing in Rural Areas
Čáslava, Petr ; RNDr.Jiří Svoboda,CSc.,DSc. (referee) ; Hudec, Mojmír (referee) ; Gaillyová, Yvonna (referee) ; Urbášková, Hana (advisor)
While I spent 7 years of study, experience and dedication to this work, the building construction has passed evolution from construction boom to contemporary building crisis. Demand for cheap building construction, materials and family housing increased sharply. Energy prices are rising every year... It seems that we will all have to deal with our essential task today or in the near future . This task is mean to prevent the current rate of degradation and destruction of our planet's climate and our environment. In this point of view, it looks the question of energy-saving construction very topical. By entering the study was to examine the possibilities of environmental friendly housing in rural areas in terms of environmental issues. My hypothesis was if can I determine the suitable candidate for the construction of passive houses themselves by comparing their characteristic of pre-defined construction samples. My objective is to offer builders and designers overview of suitable building systems with the possibility to compare the various factors influencing the decision on the selection of a builder´s construction for a house. The thesis presents the comparison of seven structural systems as a basic element of architecture. In the implementation of energy-efficient house is an architectural form often conditioned by structure. For this reason it is necessary to offer this kind of overview with options and parameters of individual building systems, which can then be used by architect to design a house for the builder - free and easy realization of his own, let´s say DIY (do it yourself). For builders (mean investors) of DIY houses is economy and finance a crucial question, therefore, for this reason I will evaluate suitable building system which is relative performance vs. price in the end. It is necessary to take into account the architecture of the house and especially the space layout and design and the attitude with the context of the rural areas environment. My pupose was to prove that good architectural design can be used with of low-cost, energy-saving and environmental friendly house built in DIY way.
