Analysis of economic and operational-technical area of housing
Jiříková, Monika ; Gebeltová, Zdeňka (advisor) ; Barbora, Barbora (referee)
The bachelor thesis Analysis of economic and operational-technical area of housing is divided into two parts, i.e. a theoretical part and practical part.
The thesis describes different types of energy used in housing. It focuses on methods that help reduce operating costs and deals with modern technologies such as
low-energy and passive houses, domestic photovoltaic power plants, heat pumps and biomass boilers.
The theoretical part is focused on various options of heating, the consumption of electricity, gas, water and the costs associated with the operation of a house.
The practical part describes a chosen family house, its heating system with the use of gas and solid fuels, and thermal insulation whose quality was measured by thermo-vision measuring methods. Further described herein is the power consumption of several energy-inefficient appliances. This part also quantifies electricity savings as a result of the installation of a domestic photovoltaic power plant, the change of electricity supplier and the replacement of energy-hungry appliances by the energy-efficient ones. This section lists individual measurements of the consumption of electricity, gas, water and the amount of electricity produced by the domestic photovoltaic power plant. All this is evaluated and the data are compared to show the difference of status before the introduction of savings measures and after their implementation.

Komparace teorií Keynese, Akerlofa a Hayeka o životním elánu
Konderlová, Dominika
Comparison of the theories of Keynes, Akerlof and Hayek about the animal spirits. Bachelor thesis. Brno: Mendel University, 2016. This bachelor thesis is focused on finding connections between their animal spirits and the existence of the order in macroeconomics by various authors. The aim is to analyze and compare the attitude of John Maynard Keynes, George Arthur Akerlof, Friedrich August von Hayek and other relevant economists the problem of animal spirits. Work includes in particular views on two very different theories - theories of Keynes and Hayek. Furthermore, a comparison of these two theories and others theories that have evolved from Keynesianism. Attention is also paid to the views of selected contemporary economists on the issue of the financial crisis.

Efektivnost využití elektronických aukcí ve veřejném sektoru v porovnání se soukromým sektorem
Hrabalová, Kristýna
This thesis deals with the evaluation of effectiveness of the use of electronic auc-tions in the public and private sectors. Basic concepts, especially those concerning electronic auctions in terms of public tenders, are characterised in the thesis. It also describes the tenders in private sector in the form of an electronic auction. The practical part is devoted to an analysis of specific electronic auctions, which were made in this sectors. The goal is to find out to what commodities are e-auctions implemented frequently, which is achieved savings, how many suppliers are participating in the e-auction. Then, the comparison of individual sectors in specific commodities based on the selected factors.

The possibilities electricity savings of refrigeration and cooling equipment according to the distribution rate - the cold storage
Pálka, Marek ; Šlezingr, Jan (referee) ; Macháček, Jan (advisor)
This bachelor´s thesis is focused on the possibilities of electricity savings of the freezing equipment, which would work only in low distribution rate and it would be disconnected from the power source in the high distribution rate. In this work, a total research in the field of refrigeration and cooling equipment, both technological circuits, as well as the principles of temperature regulation and food storage process is made. Another part of the work is focused on freezer testing standards and regulations. Much of the work is devoted to the experimental measurements, in which different types of rates on the given freezer equipment and with them associated the possibilities savings relative to other rates are measured. Another objective of the experimental measurement is to find out the temperature behaviour in the various parts of a freezing apparatus according to the switching time of the rates. There are overall experimental measurements evaluated and the possibility of electricity savings in direct reliance to the processes ongoing in the food during long term storage in the freezer in the unstable storage temperature In the conclusion of the work.

Saving fans in HVAC systems
Klügl, Martin ; Rubina, Aleš (referee) ; Rubinová, Olga (advisor)
This Thesis deals with the fans, their properties and characteristics. The Project part is about design of the HVAC equipment in the centralised and decentralised option for the assigned building. The Project part is focused on the design and evaluation of the fans more specifically. The Experimental part is about measurement of parameters and characteristics of the fans. The results are analyzed and compared. The results are compared with current energy efficiency reguirements for fans.

Assessment of the Impact of Thermal Insulation Performance of a Detached House in the Zlín Disctrict on Running Expenses of this Property
Velísková, Eva ; Uhlová, Eva (referee) ; Weigel, Lubomír (advisor)
Master´s thesis deals with an assessment of investment return in saving precurations. The issue is used on an ordinary detached family house. The assessment is done in more variants to reach an objective comparison of the most advantageous investments. In the first part there is a comprehensive theory explaining the connections of the procedures and the algorithms of the calculations. The second part is calculation, especially from the thermal engineering, energy rating of buildings and the economic return on investment. The third part is an evaluation which, on the basis of the experiences and the results from the thesis, offers a proces show to think in case of intended reconstruction and how to evaluate the efficiency of the investments in the saving precurations.

Cleaning of ventilation systems and potential energy savings
Lapáček, Milan ; Rubina, Aleš (referee) ; Máša, Vítězslav (advisor)
The main aim of this thesis is to explore fouling of air ducts and its influence on energy consumption of HVAC systems. The first part focuses on typical parts that create the IAQ in buildings and on evaluating energy consumption of air transportation. The following section deals with the theories of fluid flow, flow regimes and pressure losses that are created as a side effect. The thesis outlines possible methods of assessing the impact of pollution with an emphasis on pressure losses and their influence on the fan power consumption. The actual experimental measurement, conducted in a selected industrial plant, is focused on an influence of cleanness of textile diffuser on HVAC device power consumption. For the further research of this process, measuring equipment with suitable measurement method is designed and constructed.
