Microphotovoltaic systems
Nováček, Richard ; Jandová, Kristýna (referee) ; Vaněk, Jiří (advisor)
Master thesis deals with photovoltaic components and their principles. Evaluate the types of photovoltaic systems and their impact on the transmission system. The thesis deals with financial support to small and micro-photovoltaic systems, which can be used in terms of legislation of the Czech Republic. There are also described the changes in the amendment to the energy act and effect on the price of electricity in households. Compared with the domestic photovoltaic rest of the world and the view of the German energy concept. Part of the theoretical design of a hybrid photovoltaic plant, including the use of heat pump. Thesis deals with using hybrid photovoltaic plant and economic viability of the proposed system. The last part deals with the implementation of the proposed system and assesses the true value from those anticipated in the design.

Civic amenities building
Tesař, Ondřej ; Svoboda, David (referee) ; Berková, Petra (advisor)
The aim of this Master´s project is the design of the elementary art school in Slavkov u Brna. The thesis is divided into three parts. The first part deals with architectural and structural design of the building, the second part with design of selected building services, and the third part with a noise study of the building. The building has two floors and a flat green roof. It is operationally divided into two sections with a common entrance - the art school itself and the concert hall. The first section consists of the office, six classrooms, a room for music theory, a choir room, a storage room, and sanitary facilities. The second section includes the concert hall, gallery, foyer, prep room, and sanitary facilities. The technical equipment of the building is located on the second floor. The building has load-bearing ceramic masonry walls, based on plain concrete foundation strips. The floor and roof structures are designed as cast-in-place reinforced concrete slabs. The partitions design is ceramic masonry units and acoustic plasterboard walls. The facade design combines greenery and ventilated cladding. The design building services include heating with two heat pumps, ventilation and cooling with two air ventilation systems, rainwater management for toilet flushing, artificial lighting, and photovoltaic power plants for the building services. The noise study covers issues of sound insulation of the building structures, reverberation time in selected rooms, and an urban acoustic study. The result is the correct design of the building in terms of acoustic comfort.

Apartment building Jemnice
Dlabaja, Adam ; Burianová, Lenka (referee) ; Petříček, Tomáš (advisor)
This bachelor thesis elaborates the project documentation for the construction of an apartment building in the village Jemnice, located in the Vysočina Region. The apartment building has two residential floors (and one basement floor) and has four residential units and common areas of the house. The vertical loadbearing structures are made of ceramic brick technology Porotherm 50T Profi Dryfix with integrated mineral wool in cavities. Horizontal structures are monolithic. The roof is made up of a flat roof with extensive greenery. The design emphasized increased comfort in use and the overall modern concept of an apartment building.

Energy self-sufficiency residential units
Orlová, Lenka ; Škorpík, Adam (referee) ; Výskala, Miloslav (advisor)
This Bachelor’s thesis deals with the special community way of living in the residential unit called cohousing. The aim of the practical part is to define the possibillities of the heat and electrical supply to the cohousing by the renewable energy, make a price calculation and specify the return of the investment.

Energy usage of beer production
Maťa, Jakub ; Tuhovčák, Ján (referee) ; Hejčík, Jiří (advisor)
The bachelor thesis deals with the issue of energy consumption of beer production. The first part focuses on the technology of beer production itself, the understanding of which is a key prerequisite for assessing the possibility of using a heat pump for this process. The main part then describes the individual processes and their energy consumption. Finally, it evaluates the use of a heat pump and shows if it could reduce the energy requirements of beer production.

Interiors of small and medium enterprises as a source of waste heat for a heat pump
Valachovič, Filip ; Miklas, Václav (referee) ; Máša, Vítězslav (advisor)
Environmental problems and the recent high rise in energy prices are forcing us to look for more sophisticated and more energy-efficient solutions. As a result, more and more renewable energy sources and waste heat are being used. Sources of waste heat, which have so far remained outside the area of interest, such as waste heat contained in the air of industrial interiors, are thus becoming the subject of interest. This waste heat undoubtedly has huge potential in many industries. The use of waste heat is always complemented by a certain technology. In terms of operating costs and the environment, the heat pump seems to be a perspective solution. The main goal of the presented thesis is to evaluate the application potential of heat pumps for the use of waste heat contained in the air of the interiors of small and medium enterprises. The first part deals with an overview of available technologies for the use of waste heat, introduction to heat pump technology, the issue of heat load of industrial buildings and due to the possibility of using a heat pump for cooling the interior, attention is also paid to hygienic requirements for the quality of the interior. The second part of the work presents a conceptual design of the integration of the heat pump into the selected process – laundry facility. The methodology of the solution consists of the selection and analysis of the process in terms of heat energy, heat pump design, economic analysis, and evaluation of the achieved results. The currently available waste heat in the air of the examined laundry corresponds to 37 kJ and the heat load corresponds to the heat output of 526 kW. The minimum heat output of the heat pump for heating 4.3 m3 of water per hour corresponds to 170 kW at a compressor electrical input of approximately 23 kW. This parameters, current energy prices, an estimated investment of CZK 1.5 million and compared to water heating by natural gas combustion give a payback return in less than 6 months. Given the current energy prices, it can be stated that the heat pump is the optimal solution in this case. It is surprising that no work on this topic has been created yet and it can be stated that the diploma thesis presents a completely unique solution with a high potential not only in the laundry process.

Using a heat pump
Tretera, Robin ; Křivík, Petr (referee) ; Jandová, Kristýna (advisor)
This diploma thesis provides basic information about the thermal pumps and photovoltaic systems. The heat pumps are described regarding their construction and sources of low potential heat. The description of photovoltaic systems explains the main principle of transformation the solar light to electric power and possible cooperation of this systems with the heat pumps. In practical part of the thesis there is a description of the assessed building and calculation of its thermal losses. It is followed by three designs of the thermal pump systems which are supposed to replace the original way of heating - the electric boiler. One of the designs is supported by photovoltaic system. The final part of the thesis provides the calculation of required heat sources for house and water heating, the operation expanses of all three heat pump designs, prices of electric energy and economical reliability of described solutions.
