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.

Energy Management of Administrative and Industrial Buildings
Coufal, Jaroslav ; Jaroš, Michal (referee) ; Hejčík, Jiří (advisor)
Nowadays, energy management is very important in terms of trying to save the environmental impact of human activities. If we want to have beautiful nature around us, it is important to think conscientiously in our consumption. In my bachelor thesis I describe the requirements of energy management. The goal of my work is to define what belongs to energy management and what solutions already exist on the market.

Use of Photovoltaic Power Plant with Batteries for Warehouse and Office Spaces
Kořenek, Jan ; Vojtek, Martin (referee) ; Mastný, Petr (advisor)
This diploma thesis deals with the photovoltaic power plant in Zlín. Power plant is used for electricity supply of office building and stock. For better self-sufficiency there is designed battery system as storage for electrical energy which the object can not consume itself. In the theoretical part there are described development of photovoltaics and components used in power plants. Further there was described the building, construction of photovoltaic power plant and eventually also a subsidy program by which the project was financially supported. Main task in the practical part was to develop scripts in Matlab for evaluation of online measured data. Next point was an energetic evaluation of power plant operation. In the end there was calculated power plant return with subsidy support and without support. These calculations were done in PV SOL software. Eventually, there was evaluated how the system works and how the power generated by the photovoltaic power plant is used. In conclusion, there is summary of the measurements and calculations.

Sensitivity analysis of the energy rating of buildings
Auer, Zbyněk ; Plášek, Josef (referee) ; Šikula, Ondřej (advisor)
The master´s thesis was focused on parametric computer simulations of the energy performance of buildings. The aim is to determine the sensitivity of the individual operating and climatic influences on the final energy demand of the building, which will be reflected in final form Et-curve. Parametric simulation for building energy efficiency is planned to use the BSim and ready climatic database for a specific location in place of the assessed building. The outcome of the evaluation of the real use of property in Et-curve using a custom application.

Energy Management in Public Sector
Vosičková, Kateřina ; Tichá, Ivana (advisor) ; Petr, Petr (referee)
The main goal of this thesis called Energy Management in Public Sector is to analyze the current state of the facilities and premises of Prostějov municipality with the emphasis on power and gas supplies and the prospective changes in energy consumption. The first part of the thesis focuses on defining energy management, the role of energy manager, renewable and non-renewable energy sources, and relevant Czech and European legislation. Furthermore, it covers the strategic documents pertaining to energy management such as state energy policy, energy audits and energy performance certificates. The second part represents the practical part which is devoted to the implementation of energy management and introduction of energy management software for controlling, measuring and evaluating consumption levels, and attempts to find cheaper power and gas supplies. The data collected in the practical part of the thesis serve as a basis for a proposal ensuring power savings and convenient supplies for facilities operated or funded by Prostějov municipality.

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.

Energy and water management in a residential building
Auer, Zbyněk ; Vendlová, Lucie (referee) ; Šikula, Ondřej (advisor)
The bachelor thesis deals with the management of energy and water in a residential building. For the energy balance of the residential building were used computational tools NKN II and outputs simulation on software BSim2000. On the basis of the calculations were prepared Et-curve for the residential building, which was subsequently supplemented by real measurement.

Energy management in office buildings
Špaček, Jan ; Svobodová, Hana (advisor) ; Šillerová, Zuzana (referee)
The aim of this bachelor thesis is to provide the reader with the comprehensive overview of the Energy Management. Nowadays, most companies are focusing on costs types of processes. It is important to stop all uneconomical utilization of sources. The energy management is important way of saving funds. The project management know-how and acquired knowledge were used in this bachelor thesis for resolution of problem with wastage of energy (especially electricity) in office buildings. It has been found that it is important to support energy management in the company. In this thesis, it is shown how to implement system of energy management in concrete conditions of company. The proposal was created for project "Unit process of energy management in ČEZ Group". Aims of project are to optimize indirect costs in building administration and to establish process based integrated system of energy management.

Energy Performance Contracting
Čtrnáctý, Jaromír ; Geuss, Erik (advisor) ; Branžovský, Antonín (referee)
Energy Performance Contracting is an energy saving method, when the supplier guarantees a certain minimal level of energy savings to the customer, as well as non-rising energy costs. The method was developed at the turn of 70's and 80's in the USA and has spread to dozens of countries around the world till today, although the rate of the EPC market development differs from country to country. The method is useful mostly for heating, electricity and gas cost savings by the end-users. In the Czech Republic, the method has been used since 1993. Until now, several dozens, or even hundreds of projects have been realized, mostly for public sector customers. This paper analyzes the current state of the EPC method usage around the world as well as in the Czech Republic, the key part comprises of the EPC principles description, based on data from real EPC contracts. The work is concluded by a SWOT analysis of the method and by a discussion of the following question: "Can EPC projects blockade the overall saving potential in some cases?" The key information source for most of the work were answers to questions sent to eight Czech ESCO companies representatives, as well as the outputs from guided interviews with four of them, which were taking place between January and May 2009.
