Reneweblw energy source at Slovakia
Szegedi, Peter ; Borbély, Richard (referee) ; Fiedler, Jan (advisor)
The bachelor thesis is divided into five main issues. The first issue is dealing with history of exploitation of water as a power supply in Slovakia and is describing current situation of exploitation of watercourses. The next part of the thesis is describing a present condition of power industry in Slovakia, its future perspective and a possibility of deriving benefit from the most perspective renewable resources of energy. The essential issue handles with water power stations ant its description. The last capture is focused on small hydroelectric power stations and technic – economical evaluation of three concrete SHPS. The conclusion is attending to short overview of information obtained by writing the bachelor thesis and to author’s own estimation of development of renewable energy sources situation in Slovakia.

Design of a micro waterpower turbines for low head and low dicharge
Macek, Libor ; Fic, Miloslav (referee) ; Štigler, Jaroslav (advisor)
This diploma thesis discusses the issue of finding type of water turbine for very low heads and low discharges, which could be operated as mobile micro hydropower plant in island mode. Thesis deals with summary of appropriate choices of water turbine for needs of micro hydropower plant. Essential part of diploma thesis deals with design of optimized waterwheel. Waterwheel was chosen because commercial high-speed turbines have low efficiency for low heads. Waterwheel was manufactured and measured in laboratories of Fluid engineering. Measurement output was discharge and efficiency characteristic of turbine. The price calculation was made after manufacture.

The tooth pump in the turbine regime
Tyburec, Adam ; Dobšáková, Lenka (referee) ; Haluza, Miloslav (advisor)
The objective of this diploma study is to develop and secure production of gear turbine with very low specific speed in comparison with conventional turbines. The first part of the work deals with already performed research of similar hydrostatic turbines. It is followed by construction design, including complete drawing documentation. The production of the prototype is secured by an external company. Finally, an experimental measurement of the characteristics of the designed turbine is performed in the laboratories of Fluid Engineering.

Kindergarten
Hess, Samuel ; Jelínek, Petr (referee) ; Struhala, Karel (advisor)
The master's thesis deals with the design of an NZEB kindergarten in Třebíč. The building is single-storey with a flat roof. Next to the building there are 15 parking spaces, 3 of them are for electric car charging. The centre of the building consists of staff facilities and spaces for building services, the rest of the building includes sanitary facilities for children, changing rooms and classrooms. The building is based on a foundation slab that rests on a layer of foam glass granulate. The external masonry is made of ceramic blocks insulated with EPS ETICS. The internal load-bearing and partition masonry is made of unfired clay blocks, which are plastered with clay plaster. The roof structure is made of prefabricated pre-stressed concrete panels, which are sloped outwards. The building is heated by a ground to water heat pump, which will heat the water for underfloor heating, the HVAC unit and hot water distribution. Intelligent LED lighting is installed throughout the building. There are photovoltaic panels on the roof to generate electricity. Rainwater is used for flushing and watering the garden. Furthermore, in my master’s thesis I addressed the possibilities of using rainwater in roof drains to generate electricity. There, I calculate different possibilities and ways to use rainwater as efficiently as possible to generate electricity. A Pelton turbine is used to generate power, which is driven by the force of the water current.
