Single-family house in Kostníky
Hodková, Zuzana ; Jechová, Marie (referee) ; Ostrý, Milan (advisor)
This bachelor’s thesis focuses into a detached near-zero-energy house in Kostníky. It includes documentation of architectural-structural design, including drawings, fire safety design, and building physics, along with documentation for building services safety. It is a two-storeys building for a family of four. The house is planned with two flat roofs and is based on a double layer of XPS panels. Reinforced concrete floor slabs and sand-lime masonry are used for load-bearing construction. Building envelope is insulated with polystyrene combined with mineral wool. The layout of the ground floor includes an entry hall with a walk-in closet, a bathroom, a study, a living area with a kitchen corner, a technical room, and a garage. The first floor is a private zone with children's rooms, a master bedroom, a bathroom, and a walk-in closet. Rainwater from the roof will be directed to a storage tank, where it will be reused with the assistance of a pump and a discharge device. Rainwater utilization is implemented for toilet flushing, while remaining water needs are supplemented from the public water supply. Wastewater is directed into the public sewage system. Ventilation in living areas is managed by an air handling unit and ceiling outlet. For heating, a ground-water heat pump is proposed to heat water for underfloor heating. Drinking water is heated by using a storage water heater. Electricity is supplied from the public grid and supplemented by photovoltaic panels. The energy performance certificate of the buildings was prepared by the Energetika software and the construction of the Detached house in Kostníky has been classified into class A (very efficient).

Energy-reducing systems designed for homes
Fortelný, Lukáš ; Lachman, Jakub (referee) ; Toman, Filip (advisor)
This bachelor's thesis deals with the possibilities of using alternative energy sources and their accumulation to increase the energy independence of family houses. The theoretical part describes a number of technologies, including photovoltaic and photothermal systems, wind turbines, heat pumps, battery and thermal energy storage, emphasizing their principles, design, and factors affecting their performance. The practical part focuses on the application of selected systems to a model family house, where the costs, return on investment, and the energy potential of the systems are evaluated. Finally, the returns based on the practical part are interpreted together with the factors that influence them, taking into account the economic viability and potential environmental benefits.

Photovoltaic system in cooperation with a charging station for electric vehicles
Zerzán, Jan ; Morávek, Jan (referee) ; Mastný, Petr (advisor)
The thesis deals with the design of photovoltaic power plant with accumulation and charging station for an electric car for a family house located in the Pardubice region. First, the individual parts of photovoltaic system are theoretically described and then the requiments for connection to distribution system are described. At the end of the theoretical part, the subsidy program is described. The practical part consists of the design of the photovoltaic system and subsequently it’s project documentation. Another topic in the thesis is the simulation and control of the energy flows of the designed PV plant with batteries and EV charger in Matlab. Towards the end of the thesis an economic balance sheet is created.

Feasibility study pumped storage hydropower plant in a particular locality
Vaněk, Michal ; Štigler, Jaroslav (referee) ; Hudec, Martin (advisor)
Electric energy storage represents an area, which needs to be further developed in order to accommodate more installed capacity of wind and solar power plants in the electric grids. Pumped hydro energy storage still remains ahead of other storage technologies in terms of achievable storage capacity. However, environment protection which is one of the obstacles for further PHES development in Europe causes significant reduction of suitable sites. It is therefore useful to examine also those sites, which seem to be less favourable for PHES at the first glance. This thesis deals with a feasibility study of a PHES on place of a former graphite surface mine. The thesis includes computation of basic capacities, choice of a suitable machine arrangement and introduction into PHES feasibility issues in electric grids. Two possible solutions of a smaller PHES that differ in their capacities were suggested based on available materials about the site as well as on available materials from Francis pump turbine model research. In case of both solutions a binary machine set is used and the available capacities are in small tens of megawatts. However, there is a wide head variation at the site, which causes significant power variation. Concerning the feasibility of the PHES, it is very uncertain that the participation in the day-ahead electricity market, would provide enough revenue to cover operation and capital costs. A following economic analysis investigating the capital costs of this particular PHES would be beneficial, as well as more detailed design of the reservoirs.

Heat storage in solar thermal systems
Mokriš, Lukáš ; Hejčík, Jiří (referee) ; Charvát, Pavel (advisor)
In this bachelor’s thesis are described methods of heat storage in solar thermal systems. Solar energy is retrieved in form of solar radiation, that is processed and stored in the form of sensible heat of solid materials and liquids, as heat of fusion of some material or as chemical heat, which is created during reversible chemical reactions.

Accumulation of electricity from renewable sources
Plíšek, Petr ; Špiláček, Michal (referee) ; Pospíšil, Jiří (advisor)
This diploma thesis deals with the issue of accumulation of electricity produced by renewable sources. The first part focuses on the description of possible ways of accumulation, especially with focus on those methods, that are suitable for renewable energy sources. The next part deals with the design of the accumulation energy in the compressed air for the selected photovoltaic power plant. The necessity of designing a particular method of energy storage, is also its technical and economic analysis, which is the content of the last part of the thesis.
