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.

Polyfunctional zone MOŘICE okr. Prostějov
Orinčák, Denis ; Vojtová, Lea (referee) ; Dýr, Petr (advisor)
The topic of the diploma thesis is the Mořice Agricultural Business Cooperative. (Hereinafter referred to as ZOD Mořice). This topic is a continuation of the pre-diploma project ZOD Mořice -Vitčice area. ZOD Mořice owns 4 complexes of agricultural facilities. Mořice - Vitčice - Vrchoslavice- Pavlovice u Kojetína. The main concept consists of the division of operations into individual complexes, according to the analyses and ideas of the investor. Vrchoslavice - livestock production (existing, not addressed). Pavlovice u Kojetína - business (proposal - lower years). Vitčice - housing for pensioners with limited mobility and independent pensioners (proposal -pre-diploma project). Mořice - architectural and urban planning study of the area, supplemented by housing units for workers and starter homes (proposal - diploma thesis). I am proposing to place silos and a biogas plant in the area and adding a building for recycling solar panels. The recycling operation will be in one of the existing warehouse buildings. I am also suggesting reserve areas for future use for the sale of homemade products. The most detailed part that is addressed in the thesis is the housing units. The housing units will be used, as service apartments and starter homes, possibly for housing for pensioners without mobility limitations. The concept follows the basic axis of existing buildings and streets. The design uses a housegarden relation. I am trying to preserve the structure of the village and not to create urban elements in it. The roofs are gabled. The facades made of brick strips are meant to make it clear that the houses are close to the industrial zone. I am separating the entire set of dwelling units from the agricultural area with a mound of earth that is on the site and has no other use.

Polyfunctional zone MOŘICE okr. Prostějov
Janovská, Tereza ; Vojtová, Lea (referee) ; Dýr, Petr (advisor)
The task of the diploma thesis is to prepare an architectural-urban study of a large multifunctional complex of the AGRISPOL company in the village of Mořice. The proposal is to have a wide scope, design of biogas plant, storage facilities, silos, internal roads, accommodation and recreation. The agricultural centre owns four agricultural sites, Mořice, Vitčice, Vrchoslavice and Pavlovice near Kojetín. The topic of the pre-diploma thesis was the agricultural centre Vitčice. The main idea of the thesis was to design efficient communications, layout and arrangement of the biogas plant, revitalization of garages and workshops, design of storage halls for the purposes of the cooperative or for rent. The eastern part of the plot is designated for short-term housing and senior housing in the proposed nursing home, supplemented by services such as manicure, pedicure, hairdresser. These two units are divided into almost two identical buildings that resemble a hockey stick in shape. The combination of these two shapes has created an inner courtyard which serves as a garden/park for the adjacent accommodation units. The park will be freely accessible to the public. The capacity of the nursing home is 16 accommodation units. The units include a hallway, private bathroom and a living room with kitchenette. The capacity of the adjacent apartment building with an adjacent multifunctional part is 8 flats of 1+kk size and 9 flats of 2+kk size. The apartments are designed as starter housing for young couples or for accommodation of AGRISPOL employees. It is a form of short-term housing.

Integration of a technology for digestate thickening in a biogas plant
Miklas, Václav ; Touš, Michal (referee) ; Vondra, Marek (advisor)
This diploma thesis is mainly focused on the digestate thickening in a biogas plant. First, overview of the biogas technology in the Czech Republic is presented. Furthermore, problems with waste heat utilization and processing of fermentation residues (digestate) are described in more detail. Based on the research, multi-stage flash (MSF) evaporation was chosen as the technology for the digestate thickening. The main part deals with the integration of the chosen technology into a biogas plant process. The programming language Python was used to simplify the given task. In the preliminary stage, a complex mathematical model of a biogas plant was created, focusing particularly on the mass and energy balances. Subsequently, a computational model of the MSF evaporator was programmed. A procedure for the integration was suggested using the sensitivity analyses. Additionally, the model of a biogas plant was extended with the MSF evaporator. The key outcome of the thesis is a technical-economic analysis in which the impact of digestate transport price and electricity feed-in tariff on payback period is investigated. The results suggest profitability of MSF evaporator for biogas plants without subsidized feed-in tariff. Contrastingly, installation of MSF evaporator in older biogas plants with subsidized feed-in tariff can be economically viable only in cases of significantly longer transport distances.
