New building boarding house with restaurant
Zelman, Martin ; Krupica, Roman (referee) ; Jelínek, Petr (advisor)
The subject of this thesis is the elaboration of the project documentation of a guesthouse with a restaurant located in Deštné in the Orlické Mountains. The thesis contains three parts. The first part deals with the architectural and structural design of a detached three-storey building. The first floor houses the restaurant, an entrance area for the guesthouse, and technical facilities of the building. The second and third floors are intended for accommodation and recreation of guests. The structural system is designed as a transverse wall with a longitudinal stiffening wall. The second part deals with the technology of the building environment. A wood pellet boiler is designed as the energy source for heating and hot water. A VRV system is used for space cooling. Photovoltaic panels are placed on the roof to generate electricity. The captured rainwater will be used to flush the toilets. The ventilation of the individual rooms is provided mainly by forced ventilation. The third part consists of the development of an energy study, where different combinations of the considered options are proposed, especially within the changing heat sources. For the development of different options, I use the same proposed reference building. The output of this part is an evaluation and comparison of the individual options with each other. Furthermore, selecting and incorporating the best option into the previous parts of the thesis in terms of primary energy from non-renewable heat sources and indicative operating costs.

Information and communication technologies in energetics
Stavinoha, Jakub ; Škoda, Jan (referee) ; Baxant, Petr (advisor)
The thesis is focused on the information and communication technologies used in the energetic. Problematic areas in energetic which are regulation, metering, control of waste minimalizations, expense and maximalization of earnings. These aspects lead to implementing expert systems, which have to process this bulk of information necessary for increasing efficiency and economization of single processes. Systems used in practice have their own hierarchical structure, where every application requires specific access of selection of used components that suit to the application. First of all it is about acceptable device selection in single level of the system: metering and regulation, data acquisition out of the process and informative layer. Suitable choice flowing from previous, already settled up application is possible to reach maximum efficiency of the whole system. In the thesis there are introduced systems used in practice and possibilities of increase the effectiveness of generation, transmission and distribution with ICT usage in distributed power generation. We are mainly talking about upgrade processes joined with power generation of energy, diagnostics, isolation states on the power line and usage of expert systems for distribution.

Possibility of using alternative decentralized energy sources
Pitron, Jiří ; Pěcha, Jiří (referee) ; Mastný, Petr (advisor)
The thesis concerns of the possibility by using alternative decentralized sources of energy. The first chapter describes current energy situation in the Czech Republic and consideration of future electrical energy consumption and the coverage by the renewable sources. Another part of this chapter describes each types of renewable energy with their advantages and disadvantages related to the Czech Republic. In the second chapter are introduced inputs which are appropriate for the plan of energetic system. The following theoretical chapter deals with each types of alternative energy sources using renewable source including the possibility of the installation and plan for the building. These alternative sources are sorted out by the way of using renewable sources of energy. The theoretical-practical fourth chapter concerns of the heating by the heat pump. For the detailed description was chosen the heat pump which is currently denote as appropriate alternative source of heat in household. With appropriate plan, which the thesis deals with, is this alternative source considered as proper investment. In the last chapter was assembled programme for creating models of energetic flux and calculation for the plan of heating by the heating pump air/water. This model is taken for concrete buildings related to exact outdoor temperature from previous years in concrete locality. In the end was realized validation of the software with the real measurement in concrete building.
