Decentralized collection and treatment of wastewater from settlements up to 200 PE.
Petřík, Jiří ; Raček, Jakub (referee) ; Hlavínek, Petr (advisor)
The aim of this bachelor’s thesis is to outline the issues of a decentralised system of drainage. The theoretical part of the bachelor’s thesis is processed in the form of research and focuses mainly on the possibilities of disposal of sewage and rain waters. Describes the possibility of using the treated sewage effluent, the possibility of delaying the rainwater at the place of deposition and their use. In this bachelor’s thesis is also listed technology related with this issue. In the practical part of the bachelor’s thesis deals with the proposal of the technical-economic study of a decentralised system of drainage of the municipalities Koberovice, Lísky and Lohenice, which are located in the cadastral territory of Koberovice in the district Pelhřimov.

Accumulation of energy in compressed air
Rešiliáno, Tomáš ; Kracík, Petr (referee) ; Pospíšil, Jiří (advisor)
The thesis deals with the principle and issues associated with operation of the storage power stations, known under the acronym CAES (Compressed Air Energy Storage). Examples of existing and upcoming CAES power stations from commercial sphere are listed and described there. The paper also includes an overview of basic CAES station wiring diagrams and a simplified calculation is performed to compare the efficiency of the chosen diagrams. In the final part of the thesis there is a scheme of so-called adiabatic CAES designed and calculated. For this type of device has been designed suitable wiring and a thermodynamic calculation of the cycle was performed for the purpose of evaluation.

Optimization proposal of size of PV systems
Vrzal, Martin ; Baláš, Marek (referee) ; Pospíšil, Jiří (advisor)
The master thesis deals with proposal of size optimization of PV systems. According to results of optimization, alternative solutions of photovoltaic system were proposed for family house. From the perspective of costs efficiency were compared investment costs and savings of implementation of electricity supply directly to private consumption. Particularly for each of the proposed solution, profitability assessment of comparing purchasing costs and returns on investment was performed. Theoretical part of the master thesis consists of introduction into solar radiation principles, structure and functionality of photovoltaic systems, electronics inverters and accumulation of electric energy. The practical part is focused on measuring of electricity consumption in particular family house, calculation of sunlight intensity hitting tested house, making various solutions of photovoltaic power plants placed on the family house in order to evaluate returns on investments. In conclusion are summarized all results of investigated solutions according to economics aspects.

Rainwater Management in Urban Areas
Ličková, Nina
Sustainable development efforts include the protection of natural resources. Water is one of the principal life-giving elements. Water conservation should therefore be central not only to environment conservation, but also to urban planning concepts, details and technological solutions employing the water element.
