The Use of Alternative Sources in the Building Industry
Dvořák, Jakub ; Vymazal, Tomáš (referee) ; Žižková, Nikol (advisor)
This bachelor thesis is focused on the use of waste as alternative raw materials in construction industry. The first part is dedicated to the historical development of waste management, to the valid legislation in the Czech Republic in 2017 and outlines the distribution of waste according to various criteria. The information about waste production and waste management is processed in the form of tables and graphs. The more extensive second part of the thesis uses theoretical knowledge in the field of waste management and on the base of the Waste Separation Catalog is composed a list of waste materials which can be used in construction industry. Further are described the possibilities of suitable waste utilization at production and also mentioned some particular construction products with their features.

Possibility of using alternative decentralized energy sources
Pitron, Jiří ; Pěcha, Jiří (referee) ; Mastný, Petr (advisor)
The thesis concerns of the possibility by using alternative decentralized sources of energy. The first chapter describes current energy situation in the Czech Republic and consideration of future electrical energy consumption and the coverage by the renewable sources. Another part of this chapter describes each types of renewable energy with their advantages and disadvantages related to the Czech Republic. In the second chapter are introduced inputs which are appropriate for the plan of energetic system. The following theoretical chapter deals with each types of alternative energy sources using renewable source including the possibility of the installation and plan for the building. These alternative sources are sorted out by the way of using renewable sources of energy. The theoretical-practical fourth chapter concerns of the heating by the heat pump. For the detailed description was chosen the heat pump which is currently denote as appropriate alternative source of heat in household. With appropriate plan, which the thesis deals with, is this alternative source considered as proper investment. In the last chapter was assembled programme for creating models of energetic flux and calculation for the plan of heating by the heating pump air/water. This model is taken for concrete buildings related to exact outdoor temperature from previous years in concrete locality. In the end was realized validation of the software with the real measurement in concrete building.

Photovoltaic, as an alternative source of electricity
Honka, Pavel ; Moskalík, Jiří (referee) ; Pospíšil, Jiří (advisor)
The work deals with alternative sources of energy and it concentrates on a photovoltaic. There are represented the main types of solar cells, the principles of their functioning and methods of increasing their efficiency. There is also a summary of possibilities of connection of the photovoltaic system and related methods of energy accumulation. On the basis of above mentioned extent of information there is suggested a project of photovoltaic power station which supplies a holiday house by produced energy.

Creation of laboratory exercises for Renewable sources of energy
Bajgl, Tomáš ; Jandová, Kristýna (referee) ; Křivík, Petr (advisor)
This diploma thesis deals with the transformation of solar and wind energy into electrical energy by using a photovoltaic panel and a wind turbine. The work gives insight into the Czech Republic’s issue of energetics in the context of historical development, the current state, and the expected future development. The primary attention is given to the renewable sources - the solar energy and wind energy. Basic principles of creation and manipulation of solar and wind energy are described in this work. Two laboratory tasks are created for the Renewable Energy Sources' class as a part of the practical part.

The design of alternative heating system for object Technicka T12
Bártů, Jan ; Mastný, Petr (referee) ; Pitron, Jiří (advisor)
The aim of this work is to design an alternative source for the property Technicka 12. In the first part of this work, the author introduces the methods of heating and possibilities of using renewable resources of energy for heating, including their advantages and disadvantages. In the second chapter are described alternative energy sources. In the next chapter, individual buildings are typified by size and heat requirement, defined factors influencing their consumption and described heating methods for real examples described and used methods of heating buildings in practice. In the final practical part, the heat pump ground/water is selected from the above described alternative sources, as currently the best alternative solution for large buildings. Within this practical section is described the design and proper calculation of this type of pump, including return on investment. At the end of this bachelor’s thesis was elaborated the technical report and the detail design for installation of the heat pump.

Control Processes in Energy Systems with Alternative Power Sources
Morávek, Jan ; Kolcun, Michal (referee) ; Braciník, Peter (referee) ; Mastný, Petr (advisor)
The dissertation is an publication summary focused on the field of management processes in renewable energy systems, mathematical models and optimization possibilities for large and small scale photovoltaic systems. The articles were published in foreign impacted and reviewd journals and indexed proceedings of foreign and domestic conferences. The main results of the dissertation are the design, configuration and realization of the hybrid energy system with subsequent optimization. Using the data from the laboratory system, a mathematical model was compiled and subsequently validated in the Matlab/Simulink environment for a hybrid energy system with accumulation. The options for power production optimization with photovoltaic sources are based on both operational measurements (for commercial applications) and on the analysis of power flow controllers to optimize the~energy balance (for small scale applications in private buildings).

Energy supply of mountain cottage
Flöhsler, Tomáš ; Martinec, Jiří (referee) ; Pospíšil, Jiří (advisor)
The aim of this Graduation Thesis is to devise a system of energy supply intended to provide supply of electric and heat energy to a vacation property. The main feature of this energy supply project stands for a shift from mains power supply to alternative energy supply using renewable resources. The reason for this change is the fustiness of power lines and their negative effect on the surrounding landscape. Due to the fact that authorities did not permit renovation of these power lines, the only way to preserve the functionality of the vacation property is to secure its power supply by employing renewable resources. The vacation property (a mountain cottage) is located in Hrubý Jeseník Mountains, approximately 15 kilometers from the town of Šumperk. The thesis also contains a description of the way outlying settlements are currently supplied with energy, including the possibility of accumulation and a brief description of each electrical appliance’s power consumption. In the design itself, I calculated the necessary collector surface and analyzed the most effective collector placement. As for the wind energy system, I had to found the best spot to place the turbine. Last but not least, the thesis contains the technical-economical comparison of the proposed alternatives.

Public on Development of Electricity Consumption, and Possibility to Substitute Conventional Resources in Energy Production - July 2021
Červenka, Jan ; Ďurďovič, Martin
In the July survey the Public Opinion Research Centre focused on the issue of energetics. The survey dealt with a question of the future development of electricity consumption in the country, and whether or not it is possible to replace the production of electricity from conventional sources with alternative sources. Almost three quarters of Czechs expect to increase electricity consumption in the Czech Republic in the future. The Czech public is divided on the question of whether it is possible to replace the production of electricity from conventional sources with the production of electricity from wind energy, solar radiation or biomass combustion.
