Design of domestic energy supply system using renewable energy sources
Gaborčík, Michal ; Pavelka, Tomáš (referee) ; Matoušek, Antonín (advisor)
This bachelor thesis deals with possibilities of utilization of renewable energy sources for domestic power supply. In theoretical part is created research about available technologies using solar collectors, photovoltaic systems and heat pumps. In practical part there are calculated expected values of energy needed for heating of family house, domestic hot water heating and electrical consumption of appliances. These values are bases for system design using air to water heat pump for heating and domestic hot water heating. As far as photovoltaic system is concerned there is comparative design of systems using polycrystalline and thin-layer technology. At the end both designed systems are evaluated from technical and economical points of view.

The long-term accumulation of solar collectors and the subsequent use of the heat
Litera, Jiří ; Fiedler, Jan (referee) ; Kracík, Petr (advisor)
The aim of the thesis is the design and evaluation of the long-term accumulation of solar collectors and the subsequent use of the heat. The basic principles of the use of solar energy are introduced in the theoretical part as well as the list of available heat pumps, solar collectors moreover options for the accumulation of heat are evaluated. In the practical part the system of a long-term heat accumulation for a partially restored family house is designed, where accumulation into water or gravel are the two presented options. Solar energy is collected by solar collectors and accumulated in the long term storage. The system involves water to water or ground to water heat pump that reduces the temperature of the reservoir in order to increase the temperature difference of the system. Both options require a large volume of heat collecting, including large surface of solar collectors. Because of the high cost and spatial requirements the system shows to be hardly realistic in practice. For this reason an alternative solution of a family house heating system more suitable from the economic point of view is described. As a result it was proved that system of the long-term accumulation is not an appropriate solution for heating system of family houses and it is used in places with enough space for the accumulation such as high capacity trays or flooded mines. For existing family houses (partly insulated and with a heat source such as natural gas) the usage of the heat pump eventually supported by solar collectors appears as the most sensible solution. Such solution shows a return of investment from 14 to 25 years, and contributes to sustainable development and to reduction of non-renewable primary energy.

Measuring and regulation of computer controlled solar systems: Vizualization of energetic systems
Vlčnovská Kotlíková, Silvie ; Mašek, Ivan (referee) ; Půčková, Helena (advisor)
This work is oriented on study and evaluation of performance of real operating solar system. There was made analysis of actual technological unit and there was suggested mode of measuring of nodal parameters. There was made interconnection between the head operating unit of the solar system and the web server. And there was prepared software for grafical image of time and temperature dependence and for data transfer to ready web application. It primarily talks about increase of efficiency of real technological unit through regulating of parameter that is using up of accumulated energy.

Proposal the heating system of the house
Zouhar, Adam ; Poláčik, Ján (referee) ; Baláš, Marek (advisor)
This bachelor thesis is dealing with proposals for the heating of the model house and about assessment of investments to these solutions. First, research of heating systems has been done, then the model house has been described. After that heat loss of this building and the energy needs for heating and preparing hot water have been calculated. At the end, some solutions of the heating system have been proposed. The financial comparison of these solutions has been done in the last chapter of the thesis.

Construction Project for Implementation of Houses in Slavkov - Pod Zlatou horou
Kurková, Dita ; Venkrbec, Václav (referee) ; Nečasová, Barbora (advisor)
The subject of the diploma thesis is the solution of chosen parts of the construction technology project of the 1st phase of the construction „Komplex RD Slavkov, Pod Zlatou horou“. These are 4 semi-detached houses, overall 8 family houses. The work deals with technological regulations for the superstructure including roof, study of the realization of the construction technology project, design of the main construction machines and mechanisms and control and test plan. For the whole construction is elaborated time and financial plan in two variants, namely the gradual and current method of construction, and a detailed schedule for one semi-detached house. The technical report of the building site equipment is completed with the drawings, itemized budget of the building part of the house, noise study and specialization focused on the photovoltaic system, with an alternative solution to use solar collectors. The thesis also includes a case study of construction methods focused on the gradual and current method of construction.

Heating of the residential building
Kašpar, Radek ; Horák, Petr (referee) ; Počinková, Marcela (advisor)
The subject of this bachelor's thesis is solution for heating and warm water preparation. The project contains more option of heat source for residential building. The first option source of heat is a gas condensing boiler. In the second option, the object is heated by a pellet boiler and hot water portion will cover the solar system. The theoretical part is a description of renewable energy use in residential building.

Energy Performance Certificate Buildings with Nearly Zero Energy Consumption
Odstrčilíková, Aneta ; Vyhlídalová, Karolína (referee) ; Horák, Petr (advisor)
The bachelor's thesis deals with the evaluation of the energy performance of the residential building in Brno. The theoretical part is about solar collectors and their distribution. In the computational part, it compares the non-renewable primary energy and the total supplied primary energy for the designed variants. It analyzes the energy needs and flows of the building. In part C there are two energy performance certificate of building – for the initial state and the designed state.
