Influence of heating water temperature on efficiency of heating system
Hliboký, Samuel ; Poláčik, Ján (referee) ; Pospíšil, Jiří (advisor)
The content of this bachelor thesis is to describe ways of increasing efficiency of heating in a family house. Thesis is divided into theoretical and practical part. The theoretical part is dealing with principle of function of gas boilers and ways of decreasing the temperature of water in heating system. The practical part of thesis includes economic-technical evaluation of replacement of standard gas boiler by condensing boiler, based on return of investment.

Heat pump heating for a house
Loibl, Jan ; Hrnčířová, Michaela (referee) ; Nerud, Pavel (advisor)
The theoretical part of the bachelor thesis deals with introducing to the issue of heat pump systems. The functioning principle of the most widely used heat pump type is explained here as well as its coeficient of performance, its operational modes and fundamental components. In addition, possible ways of heat pump systems application in terms of obtaining lowpotential heat are introduced. In the practical part the calculation of thermal loss of selected family house is discussed together with the calculation of heat requirements for heating and domestic hot water. The following part focuses on the selection of the most appropriate type of heat pump systems for covering heat demands of the selected house. The final part poses economical assesment of the designed heat pump system including the calculation of investment recovery.

Efficiency analysis of green buildings operations
Muškát, Petr ; Dvorská, Michaela (referee) ; Ivanička, Koloman (advisor)
The main topic of my bachelor’s work is comparison heating costs of a family double house with original wall fillings and after applying external insulation including additional saving measures. My work is taking in count a possibility of applying for financial grant organised by European Union. This grant is called Green for savings and it is a helping tool leading to energy savings and modernization of old buildings. Next part is focused on used materials in nowadays for building revitalization and reconstructions. These materials has to meet high standards and criteria in thermo-insulation combined with simple construction solution. Manufacturers in these days tend to raise the quality of their products to maximal possible level.

The Betting Agent
Bělohlávek, Jiří ; Rozman, Jaroslav (referee) ; Grulich, Lukáš (advisor)
This master thesis deals with design and implementation of betting agent. It covers issues such as theoretical background of an online betting, probability and statistics. In its first part it is focused on data mining and explains the principle of knowledge mining form data warehouses and certain methods suitable for different types of tasks. Second, it is concerned with neural networks and algorithm of back-propagation. All the findings are demonstrated on and supported by graphs and histograms of data analysis, made via SAS Enterprise Miner program. In conclusion, the thesis summarizes all the results and offers specific methods of extension of the agent.

Study on the potential of an integrated waste-to-energy unit
Freisleben, Vít ; Turek, Vojtěch (referee) ; Jegla, Zdeněk (advisor)
This diploma thesis is focused on the design of technological modifications of the existing industrial unit „waste-to-energy“, used for thermal treatment of process waste gases containing VOC and CO while flue gas is produced. The main objective of the existing unit modification is to improve its operating parameters considering economy, ecology and energy utilization. In the first part, the current industrial plant was presented with all necessary process data. Furthermore, all the key equipment used for the waste gases treatment or for the utilization of waste heat was identified. In the main part of the thesis there are performed modifications of the existing unit including the technology of existing heat exchangers intensification, the design of new and more efficient heat exchangers and finally the catalytic oxidation technology implementation for the decomposition of pollutants contained in the waste gas. The result of the thesis is a technical, economic and ecological comparison of the proposed technological modifications with the existing operation.

An evaluation of the effectiveness of investments in energy savings
Ondráček, Jan ; Klímová, Lenka (referee) ; Vaňková, Lucie (advisor)
Investments in energy saving of buildings is associated with a reduction in the operating costs, but it is also an effort to improve the quality of the environment. The main impulse are constantly rising energy prices and deteriorating air quality. The diploma thesis deals with the return on investment in thermal insulation of residential houses. The theoretical part describes the different definitions from the field of investments, pricing and energy modifications. In the practical part are considered two apartment buildings, the first insulated, non-insulated second. The next step is quantifying of the investment cost of such insulation designed with the calculation of payback period, net present value and internal rate of return. At the end of the work is the evaluation of the effectiveness of investments.

The proposal of lean production implementation in a industrial enterprise
Nachtmann, Pavel ; Bartošek, Vladimír (referee) ; Jurová, Marie (advisor)
This master´s thesis describes the production process in Japanese enterprise Daikin Device Czech Republic s.r.o. with emphasis on the production schedule, equipment and manufacturing system with elements of lean production. According to the production process analysis at the given production line a new solution of the production process has been suggested to increase production efficiency. This conception has been implemented and compared to the production process before, as well as to the assumed production process after increasing the efficiency.

Possibilities of energy savings
Palkovič, Peter ; Fišer, Jan (referee) ; Hejčík, Jiří (advisor)
The work is mainly engaged in electricity savings opportunities in fair housing unit 3+1 in the locality Brno - Černá Pole due to confusion classic appliances for more efficient appliances with lower power consumption. In the introductory part of the thesis is a description of the energy label for household appliances with calculations for inclusion in the energy classes according to the most recent applicable regulations, directives and regulations of the Ministry of Industry and Trade. The next section describes the structure of electricity prices coupled with monthly fees and possible financial savings in changing the current supplier for another. In the last part of the thesis describes the specific consumption of each appliance is switched on and in StandBy mode and replacing them with more efficient appliances. Finally, the representation of the return on investment for those changes, calculated total annual consumption and costs for energy consumption in apartment 3+1.

The return on investment associated with construction of a residential building in Brno
Hovorková, Kamila ; Berger, Patrik (referee) ; Cupal, Martin (advisor)
This diploma thesis is focused on return on investment associated with the construction of a residential building in Brno. First, the author finds all costs associated with the construction of a residential building. Subsequently, the residential building will be evaluated according, as a complex and as an individual flats. It will also be based on the prevailing prices of rents calculated yield value of the house. Then the comparative method provides the prevailing price of apartments in the area and find out how much revenue would amount to, if the house is sold off for flats. Finally the resulting values are compared among themselves and determine the best option to deal with new residential building in Brno.
