Cuřín, Martin ; Charvát, Pavel (referee) ; Klimeš, Lubomír (advisor)
The liquefaction of gaseous fuels using renewable energy sources is a promising method for the efficient transportation and utilization of these fuels. This thesis primarily addresses the issues related to the liquefaction of natural gas, from its conditioning, liquefaction, to its storage and transportation. The economic balance evaluates three proposed scenarios for the transportation of natural gas to the Czech Republic. Additionally, the economic viability of using renewable energy sources for the liquefaction of natural gas is analysed. The aim of the thesis was to provide a basic overview of current liquefaction tech- nologies and to analyse the use of renewable energy in the process of liquefaction and seasonal storage of natural gas. The results indicate that the use of renewable sources for liquefaction can be economically advantageous and beneficial in the sustainability of the energy sector.

Townhouse
Palata, Jiří ; Dokoupilová Pazderková, Kateřina (referee) ; Ležatka, Lukáš (advisor)
The subject of the diploma thesis is the design of a set of town houses within the Veveří, Pekárenská, Kounicova and Závodní blocks in Brno. The town house represents a historical archetype that represents the ideal functional composition of the building within the compact structure of the development in the wider center of Brno. The polyfunctionality of individual houses consists of a vertical functional division, where the ground floor is usually home to commercial units intended for catering, trade, administration or small production. Urban blocks, by their closure, firmly define the boundary between private and public. Public space is fairly dedicated to all. The non-public inner block is dedicated only to residents, which provides a rare added value with its functional content from recreational sports, relaxation, gardening. Some apartments are also oriented towards the inner block, which have direct contact between the interior and the exterior. On the higher floors, access to the exterior is ensured by means of loggias, balconies and terraces of stepped floors. Part of the inner block is dedicated to a single-storey supermarket, the capacity of which follows on from the existing operation. The roof of the supermarket is a connected part of the terrain of the inner block. On the roof there is a recreational multifunctional playground, an active sports area, a terrace connected to the community hall and a community sauna. All sections have access to a shared courtyard for residents. The underground parking is situated on two floors, separated from the parking for residents and visitors to the supermarket and other commercial units. The character and spatial solution of the objects is based on knowledge of the place and the surrounding objects, which are located in the city's heritage zone on the near border of the Brno city heritage reserve. The building thus brings a new architectural layer to the place with respect for its surroundings. The building is divided by urban-architectural details, such as stepped floors, accented corners, risality, gabled roof gables, vertical material solution of the facade or the same rectangular format of vertical window openings. However, the architectural solution inspired by history is dressed in a contemporary coat, which ensures the careful use of energy, rainwater management, the support of biodiversity and, with its positive approach to the human scale, the support of social sustainability. Vegetation areas for rainwater management are located not only on roofs, but also on facades, specifically on railings, which are the subject of a separate architectural detail solution. In addition to individual town houses, the proposal also includes the creation of the structure and character of public spaces. In particular, the character of the city street Veveří is strengthened, the new Závodní street is created and the character of the existing service streets is adjusted, in which the pedestrian is favored over the driver, and adequate traffic calming solutions were chosen with the aim of supporting mobility by public transport. Professor Chudoba's memorial tree is the centerpiece of the new important public space, with its parameters of a patch. A majestic tree closes the interior of this space and creates an ideal environment for meetings with the possibility of a longer stay thanks to the situated catering facilities.

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.

Wind power plant
Šponiarová, Petra ; Prokop, Aleš (referee) ; Řehák, Kamil (advisor)
The electricity production from renewable sources is a very current topic. It also includes the electricity made by wind power plants, which the bachelor’s thesis concentrates on. An extensive research study was conducted to provide an overview of wind turbine types. Concerning wind power plants, apart from their visual impact, noise and vibration connected to their operating is an often discussed issue. The construction of a wind turbine stands for the most important role in reducing such unwanted effects. Technical experiments following specific standards and recommendations are performed to assess the impact of wind turbines-emitted noise and vibration on humans. In order to assess noise and vibration of a wind turbine a technical experiment is proposed, which uses different approaches to determine the critical components. The selection of a suitable measuring equipment and the choice of location for its subsequent use are important parts of the design. At last, the use of wind power plants is critically reviewed.
