The diploma thesis deals with the energy audit of the kindergarten building Špálova in Ostrava, according to order No. 480/2012 Sb. as amended. It is divided into three parts. The first part deals with the project of photovoltaic power plants in the energy audit, the second part analyzes the calculation procedures in the design of energy-saving measures and the third part completes the energy audit according to the requirements of the above-mentioned decree.

The subject of the “The Computer Network Design” thesis is the analysis of the current company status and a detailed analysis of its possible improvement. The present status, company demands and the brief summary of available technologies for proposed solution have been described. The optimal option for the company has been chosen. Current company costs have been analyzed and savings solution for both monthly costs for maintaining the network and purchasing cost for computer technology itself.

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 thesis deals with analysis of calcium carbide production process. The aim of the thesis is to identify and design savings resulting from the use of energy contained in flue gas, which is produced during the process. In the first part, history and applications of calcium carbide are presented. The thesis then contains mass and energy balance of calcium carbide production. Balance is related to 1 ton of the product. In conclusion, possibilities of flue gas use for coke drying are proposed. The thesis is based on the information from the calcium carbide factory located in Sundsvall, Sweden.

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.

This thesis is focused on analysis of the use of electronic reverse auctions in the construction industry in Slovakia. The theoretical part provides the basic concepts, types and participants of electronic auctions. There are also analysed in detail the electronic reverse auctions as an important tool for procurement processes in the construction industry. The practical part deals with the analysis and subsequent recommendation for the construction sector - through a questionnaire survey.

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

This diploma thesis deals with the evaluation of the benefit of cohesion policy to reduce energy consumption and preserve an attractive environment in the Czech Republic. The aim is to determine the spatial distribution and allocation of approved financial resources from fields of support related to energy savings. The primary focus is on the Operational Programme Environment - priority axis Sustainable Use of Energy and the Operational Programme Enterprise and Innovation --priority axis Energy Efficient, which are subjects of the analysis. In conclusion is summarized current information about the form of future cohesion policy after 2013.

The aim of this diploma thesis is a detailed view of a process and way of managing all the sourcing activities in the company Thermo Fischer Scientific. The focus (of my work) is a czech site of mentioned company situated in Mukařov, which, apart from production itself, is engaged also in sourcing for its own needs (where in most cases it has a decision power in its own hands) as well as for the whole company in the global measure (where it operates just as an intermediate searching for possible business partners, without any powers of decision). The main contribution of my work lies in the comparison of both of these variations and detailed investigation and description of all the activities that could help to optimize the global sourcing. I found out that entire optimizations are based on communication improvements among all the sourcing managers and technologists within the global corporation. On the basis of this fact I have projected models of documents the sourcing managers should work with, suppliers database and an information server. The result of my work is a process scheme which should contribute to the outsourced projects optimization.

The theme of this master's thesis is the elaborating of an energy audit according to the valid legislation in the Czech Republic a five-storey apartment building. The master's thesis consists of three main parts. Theoretical, Computional and Energy Audit. The theoretical part focuses on the theme of solar thermal collectors. In the calculation part, the energy consumption of the assessed object is analyzed in both the initial and the new state. The energy audit is drawn up in accordance the Decree number 480/2012 Sb. in the current version.
