Biogas production
Rybecký, Adam ; Toman, Filip (referee) ; Sitek, Tomáš (advisor)
Biogas is a stable and controllable renewable energy source that helps to reduce dependence on fossil fuels and thus reduces greenhouse gas emissions. Biogas production uses biodegradable waste, such as agricultural or food waste, thus contributing to the reduction of waste going to landfill. This bachelor thesis deals with the technology of biogas production by anaerobic digestion. The biogas production process is very sensitive to many factors where the main ones are pH in the fermenter, C/N ratio, temperature and hydraulic residence time. There are different biogas production technologies that are distinguished from each other by factors such as the dry matter content of the feedstock or by the temperature regime outside the fermenter. The most common technology for biogas production in practice is the wet fermentation method. The role of biogas in the energy mix of the Czech Republic, but also in the EU, will grow in the future, in its upgraded form to biomethane, as it is completely interchangeable with natural gas and can be used in any sector and in any form. The experimental part of this bachelor thesis deals with and describes the actual process of biogas production using wet anaerobic digestion technology and then evaluates the effects of selected factors such as temperature, nitrogen atmosphere, residence time and dilution of fermenter contents on the quality and quantity of biogas.

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.

Methods of energy treatment of municipal waste
Štork, Martin ; Köbölová, Klaudia (referee) ; Linda, Jakub (advisor)
The bachelor's thesis deals with the topic of how to deal with waste in order to obtain as much energy as possible from it. That's why we are dealing with restrictions on landfilling. In the theoretical part of the thesis, we will find the types of waste and their characteristics, as well as the ways in which waste can be worked. In the practical part of the thesis, I try to show how waste could be worked in the future, ideally for a large yield of energy and with minimal air pollution during waste processing. This results in a complete restriction of landfilling.

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.

Energy balance of biomass heating plant
Žmolík, Václav ; Šen, Hugo (referee) ; Baláš, Marek (advisor)
This thesis deals with a design of a biomass heating plant combinating a Rankin-Clausius cyklus and a CHP unit. The CHP unit fuel is a biogas and the boiler fuel is a wooden chip. The adapted CHP unit regenerates feed-water of the R-C cycles. This design is technicaly and economicalty compared with the Rankin-Clausius cycle without feed-water regeneration by the CHP unit.

Technology Transfer Center
Kršková, Nikola ; Klimek, Karel (referee) ; Myslín, Jiří (advisor) ; Čuprová, Danuše (advisor)
This bachelor thesis is focused on a new building of office building in Telc within Technology transfer center. The shape of the land is trapezoidal and it is located in immediate proximity of the 1st class road, Třebíčská street. There are some others buildings of varios function near – college, administrative houses, houses of production, hall of residence. Its top view is rounded, defined by four ring arcs. The building is gaining mass with its height. It is situated on the northeast side of an estate, plot of land No. 5782/1. There is a car park in front of the building. There are a space laboratory for research and development of biological stuff, spaces for administration and management and biogas plant controling centre inside. The dominant space is an entrance hall with a staircase. The staircase is solved in Part D - architectural detail.

UTILIZATION OF BIOGAS IN TRANSPORT
Štylárek, Milan ; Zháňal, Lubor (referee) ; Vopařil, Jan (advisor)
Objective of this bachelor thesis is evaluating the possibility of utilization of biogas as an alternative fuel for combustion engines in traffic. Production and distribution of upgraded biogas is described as well as situation of its utilization in the world. This is followed by a comparison of situation in biomethan utilization in Czech republic and Sweden. There are explained barriers to commercial placing and its possible eliminating. In the end the model study of replacement of farm vehicle fleet for CNG vehicles is described.

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.
