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.

Autonomous power system
Královský, Jaroslav ; Brázdil, Marian (referee) ; Pospíšil, Jiří (advisor)
This diploma thesis deals with available technologies when designing autonomous house. Theoretical part of this thesis shows and presents options for gaining energy from renewable resources and options for energy storage. The practical part of the thesis is focused on designing partly autonomous system for model house using renewable resources. In the thesis are three options of gainig energy for the house, from which is chosen the best option.

Identification and detection of defects on the PV system - operational measurement
Leitman, Valentín ; Morávek, Jan (referee) ; Mastný, Petr (advisor)
This work deals with the problem of identifying and detecting faults in photovoltaic systems. This thesis includes theoretical knowledge related to photovoltaic panels, the definition of measured parameters of the PV system and five ways how to identify faults in PV systems. The last part of this bachelor thesis deals with the author's contribution, which is to introduce a system for continuous monitoring data. System for continuous monitoring of data consists of measuring the power output of a photovoltaic panel and measurement using optical diagnostics using thermal camera. In conclusion are summarized individual knowledge, evaluation and recommendation of appropriate measurement methods for the detection of faults in PV systems.

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.

Energy system for energy independent object
Kaňovský, Jiří ; Pěcha, Jiří (referee) ; Mastný, Petr (advisor)
This bachelor‘s thesis deals with a design of energetic system for energetic independent family house. There are default parameters for the house defined, and an impact of house's placement in nature on thermal energy loss and on thermal energy gain due to solar radiation is described at first. There are daily diagrams of thermal energy consumption for common and heating periods derived in this thesis. An energetic system producing electric energy using photovoltaic solar panels which are placed on the house's roof is designed based on the diagrams. The thesis also introduces basic types of island energetic systems. The objective of this thesis is also a design of energetic system for heating-up (TUV) using a thermal pump, fireplace and solar collectors.

Energy-saving kindergarten building in Trutnov
Lacko, Martin ; Uher, Pavel (referee) ; Blasinski, Petr (advisor)
The aim of this master's thesis is to propose the construction of a new kindergarten with almost zero energy consumption. The building is purposefully divided into three parts, with one part serving as facilities for staff, the second part consisting of classrooms for children, and the third part comprising a speech therapy clinic. The thesis is divided into three parts. The first part focuses on the design of the structural solution, which involves a single-story, without basement structure. Load-bearing vertical structures are made of aerated concrete masonry, and horizontal load-bearing structures consist of hollow precast Spiroll panels. The building's roof is designed as a flat, single-layer, extensive green roof. The second part is dedicated to the design of the HVAC system. A heat pump air/water system is proposed as the source of heating and cooling, with a gas boiler as a bivalent source. The heating of the building will be provided through radiators, except for the classrooms, which will have floor heating. Air exchange is ensured through mechanical ventilation with heat recovery. Additionally, a hybrid photovoltaic power plant on the roof partially supplies the building with electricity. The third part involves an experiment on a ventilated facade, where temperature measurements in the air gap are conducted. The result is a comparison between an open ventilated facade and a closed ventilated facade.

Using renewable energy sources
Vaňko, Adam ; Bátora, Branislav (referee) ; Matoušek, Antonín (advisor)
Thesis deals with the issue of renewable energy sources. It contains the description of their usage at present as well as the possibilities of their installation. When dealing with the individual types of sources the thesis states their advantages, disadvantages and the facts concerning their further development. Technical development brings us new and perspective types of renewable energy sources, the description of some of them can be found in the thesis as well. The second part of the thesis is focused on the solution of electric power supply for a holiday cottage. Authonomy photovoltaic system is suitable for its application. The system is designed to have an ability to supply electrical units in the cottage during the whole year. To be able to consider profitability of the photovoltaic system installation the thesis contains the project of low voltage energy branch connection. This branch line of 1200 m in length is properly designed and the thesis states its capital costs as well. Financial comparison of the photovoltaic system costs on the one hand and the costs of low voltage branch line on the other hand in the next 30 years of usage proves the profitability of the photovoltaic system.
