The energy crisis and its possible solutions in a selected municipality in the Czech Republic
NOVOTNÁ, Karolína
The thesis focuses on the energy crisis and its alternative solutions within a selected municipality. Three research methods were used in the thesis, namely a questionnaire survey, a household real consumption survey and a semi-structured interview. The aim of the thesis was to find an alternative solution and then to determine the willingness of the residents of the selected municipality to accept it, given a higher price offer, in relation to the completed education of the individual and his/her income category. A biogas plant located near the selected village was offered as an alternative source of electricity, where the aforementioned interview was also conducted. The interview served to establish the feasibility of this proposed solution. The work was conducted as a community energy sector model where the biggest source would be a biogas plant.

Guesthouse Zátoka
Rajchl, Filip ; Šteffek, Libor (referee) ; Ostrý, Milan (advisor)
The aim of my thesis is to design new Guest house called Zátoka near the Pozlovice dam. Thesis is divided in three parts. First is part is focused on building design and construction. Second part is focused on HVAC design and renewable energy sources. Third part is focused on advanced application of BIM in building design. Guest house is two – storey building but there is one more underground storey for sport activities which is not part of the building service, but it is part of the design. Ground floor contains three guest rooms, office, utility room and air condition room and of course wind lobby and entrance hall with stairs. In the second floor we can find four guest rooms and corridor. Heating in the building is secured by pellet boiler with storage reservoir. Ventilation is provided by two air condition units. And cooling is secured by one cooling unit on the roof. Each room has radiators and cooling distribution units and ventilation. On the roof we can find 26 photovoltaic panels. Third part is focused on digital model of the building. Each part of the model contains information and whole model is one big database of information about the building which can be used through the whole life cycle of the building.

Waste-based renewable energy production
Strapko, Tibor ; Touš, Michal (referee) ; Pavlas, Martin (advisor)
Following diploma thesis deals with waste-based renewable energy production. Waste is a very heterogeneous mixture consisting of various materials with different origin. This can be either fossil or biogenic. The very substances with biogenic origin are considered renewable energy source with financial support from state. Therefore is nowadays tendency to develop a method, which can determine the biogenic waste ratio. The method, aside possible cheapest price and simplicity, should be also reliable and easy reproducible due to its usage. At the beginning, thesis focuses on the waste-to-energy facilities. Important part deals with legislative side of this topic. The reasons, why Czech Republic is behind with thermal waste treating are stated as well as Czech Republic’s obligations to European Union in the field of biodegradable municipal solid waste. Main part of thesis deals with different methods to determine biogenic waste ratio in municipal solid waste. Step by step are introduces 4 known methods, where especially sorting, balance and 14C methods are described closely. By each method are stated its major benefits and handicaps in case of using. Finally, the computational model, which is based upon balance methods equations, is introduced following with feasibility study of balance method for local conditions. The very end of the thesis brings comparison of each method results, general summary, where are results of this thesis stated and possible trends for future in this area of expertise, as well.

Kamenický, Robin ; Hájek, Zdeněk (referee) ; Maar, Tomáš (advisor)
Každodenní nedostatek pitné vody vede ke snahám tento problém řešit. Jedna z možnosti je odsolování ať už destilační, za pomoci membrán a osmózy, či dalších nekonvenčních způsobů jako je zmražení vody. Tato práce se zabývá možnostmi odsolování. Popisuje způsoby destilační, reverzní osmózu, solární odsolování a nezapomíná ani na separaci pitné vody pomoci zmražení. Spolu se získáváním pitné vody ze slané nastává také otázka energetických zdrojů. Využití fosilních paliv, obnovitelných zdrojů energie a jaderné energie, je tedy další nepostradatelné téma popisované v této práci. V neposlední řadě se zde také můžete dočíst o možném dopadu odsolování na životní prostředí, ať už z hlediska globálního v podobě možné produkce skleníkových plynů nebo dopadů lokálních. V závěrečné kapitole je podrobná ekonomická analýza odsolovacího zařízení pomoci počítačového programu DEEP. Popisované zařízení je na bázi multi effect distillation a reverzní osmózy, pro které se získává energie z jaderné elektrárny.
