Development and Implementation of Energy Savings and Energy Management Methodology in an Industrial Enterprise
Dudarev, Ivan ; Demeč, Peter (referee) ; Suchánek, Rostislav (referee) ; Blecha, Petr (advisor)
V současné době se problematika energetických úspor dostává do popředí zájmu jak na úrovni jednotlivých podniků, tak i na úrovni celého státu. Často bývá příčinou sporů ve vědeckých kruzích i mezi odborníky z praxe. Lidstvo tradičně začalo využívat energii z minerálních přírodních zdrojů, které však ve srovnání s obnovitelnými zdroji energie mají omezení. Výzkum a implementace moderních technologií jsou ztíženy otázkou investic a časově omezeny. Proto se evropská strategie energetické bezpečnosti zaměřuje na energetickou účinnost, která je jedním z nejefektivnějších způsobů zlepšení bezpečnosti spotřeby energie. Velké společnosti a podniky jsou jedním z hlavních spotřebitelů energie. Proto je tato vědecká práce zaměřena na problematiku úspor energie a zlepšování energetické účinnosti podniku. Těžiště práce spočívá ve vytvoření a zavedení metodiky pro úsporu energie a managementu hospodaření s energií ve výrobním procesu automobilového podniku. Dále je pro účely této práce vytvořen a popsán způsob vizualizace spotřeby energie v prostředí virtuální reality

Evalution of Economic Efficiency of EPC Projects
Vlčová, Zuzana ; Šourek, Bořivoj (referee) ; Korytárová, Jana (advisor)
The issue of energy saving building is a current topic of today. The increasing costs of operating buildings reduce economic efficiency of the organization operations. A large part of the operating cost is energy cost. An effective tool for improving the energy performance of buildings is an EPC method. The implementation of energy projects through EPC is offered by Energy Services Company. This thesis evaluates the economic efficiency of the project implemented by the EPC and analyses its risk factors. The subject of EPC project is modernisation of an energy sector of a hospital building. The economic efficiency of the project is interpreted on the basis of economic indicators Net Present Value, Internal Rate of Return and Profitability Index. There was also performed Monte Carlo simulation supported by Oracle Crystal Ball software within the analysis of risk factors for the project.

The Benefits and Pitfalls of Smart Meter Data Collection
Bazal, Stanislav ; Morávek, Jan (referee) ; Šedrlová, Magdalena (advisor)
In recent years, the demand for electricity has been increasing in households because various appliances and newest technologies have been used on an everyday basis. This raises concerns about the lack of electricity production around the globe. There is also a need for people to track their daily power usage in houses. The aim of this thesis is to explain the term smart metering and its benefits for both people that might use this technology in their households, and for companies. Smart meters allow people to track and control their energy consumption and eventually it might result in cheaper costs of the resources. What is more, the smart meters help consumers to know specific information about the consumption of electricity for appliances. In a global scale, the smart metering technology is used in smart grids which are more environmentally friendly power grids with higher efficiency and greater energy production. This work also focuses on the overall distribution of smart meters both in the Czech Republic and in the world. Nowadays, there are many projects in progress that are trying to switch from traditional power plants to smart grids with the intention to increase energy production and to become eco-friendly. The companies behind these projects have already published some of their researches which bring positive information about the energy production. The majority of these projects should be in progress until 2020 and some until 2025. Therefore, the final conclusion whether the smart metering technology will replace the traditional power grids and will be implemented in households cannot be drawn yet. This thesis also contains a practical part in which I create a user interface in Grafana, which is an open-source software for time series analytics. The user interface is created for a Raspberry Pi touch display which has a sensor connected to it that allows us to measure energy consumption of electricity meters. The measured values are then presented in useful graphs and gauges in Grafana, and also on the display itself.

Energy and environmental assessment of buildings
Kubínek, Tomáš ; Baroň, Alexandr (referee) ; Hirš, Jiří (advisor)
The aim of this thesis is to give a general idea of energy; what it is, how it is created (rather transformed), how it is distributed and used in many of its forms. In detail it describes how buildings are evaluated in terms of energy consumption, how can we lower this consumption and how it affects the environment. Part A, theory, gives a general idea of the theory surounding transformations, losses and uses of energy. It describes processes of assessment of buildings. Part B, calculation methods, give an idea how current CZ/EU regulations describe optimal calculation methods. These methods include: energetic, enviromental and economic evaluation of buildings or energy-saving measures. Part C, project, describes an exact measuring in Elementary School Svážná-Brno. It describes the means of obtaining information. Includes graphically processed monthly energy consumptions. It also includes list of used sensors (measuring air temperature, humidity and surface temperatures), schemes of sensors placements, schemes of building and technical systems. The main part of this project are graphs of measured data made in EXCEL with descriptions.
