Study efficiency of modern thermal insulation for buildings
Šot, Petr ; auditor, Karel Trojan, Brno, energetický (referee) ; Šťastník, Stanislav (advisor)
The bachelor´s thesis deals with the problem of thermoreflect insulation. The small part of thesis focuses on the energy demand of buildings and its problems. Then the greater extent is analysed problems by heat transfer of material. It includes effects arising from the individual methods of heat transfer and defines the level of expression of individual methods of heat transfer in materials. The thesis presents an overview of experimental methods for determining thermal insulating properties of insulators. Then there is shown a selection of the most widespread insulation materials used in today´s construction. It includes the division of insulators in terms of used materials and subsequent classification of the most used materials in these groups. Another part of thesis deals with the thermoreflect isolation. There are mentioned the necessary concepts for the study of thermoreflect thermal insulation, which include the emissivity surface, the coefficient of mutual radiation and translucency of the material. Then there is described the method heat transfer of thermoreflect isolation. On the next there are presented experimental methods of determining thermal insulating properties thermoreflect thermal-insulating material. The thesis also includes a practical part, which contains the measurement results on a small range of samples taken termoreflection insulators. In the end there is mentioned a brief realization of thermoreflection thermal insulation materials in buildings.

Energy assesment of single family house
Panovec, Jan ; Počinková,, Marcela (referee) ; Hirš, Jiří (advisor)
The aim of this bachelor’s thesis is to understand the nature of the energy assesment of building with low energy demand and energy-saving requirements. The calculations of energy intensity and experimental measurements of chosen parameters of inner microclimate in the building were done. Theoretical part includes requirements and principles of projecting buildings with low energy demand.

Energy demands balers with fixed and variable compression chamber
SKALICKÝ, Martin
This bachelor thesis focuses on the comparison of energy demands of fixed- and variable- chamber silage balers. The first part of the thesis deals with the fodder plants (importance, crop and agrophysical characteristics) and pick-up balers (agrotechnical requirements, division, description and construction of balers). The second part contains measured values and results. To compare the energy demands I have chosen the fixed-chamber silage baler CLAAS ROLLANT 250 ROTOCUT and the variable-chamber silage baler KRONE VARIOPACK 1800 MULTICUT. With both balers I compared their unit weight, performance and fuel consumption measuring. The measuring took place during the hey and silage crops (three cuttings). The gathered data was used for further calculations.

Ennergtic heftiness of storing haylage and silage into the silage bags
JANOUŠEK, Šimon
My thesis focuses on discovering power heftiness of storing harvested material into the silage bags. The theoretical part heeds the basic needs of the procedure of preservative process during preservation of fodder plants. There is a brief characteristic of most widely used technological procedures of storing harvested material into the storage area, structure of technological units, characteristic of individual means of mechanization for harvest and subsequent storage of solid pasturage. The practical part is focused on measuring of power heftiness of storing haylage and silage into the silage bags. There is also comparison of agricultural limits of power drain to other methods of stored material into the storage area.

The effectiveness of subsidies to reduce the energy intensity of enterprises
Navrátilová, Lucia ; Potluka, Oto (advisor) ; Sobotka, Ladislav (referee)
The thesis is devoted to assessing the effectiveness of subsidies spent on improving energy efficiency in the business sector. It analyzes the use of energy resources, international development in energy consumption and legislation focused on energy efficiency. Further, it analyzes two possibilities of obtaining funds for measures improving energy efficiency, subsidies and bank loans. There are given characteristics of the subsidy program Eco-Energy from the Operational program Enterprise and Innovation 2007 - 2013. In the practical part, the effectiveness of subsidies from this program is assessed by comparison of the supported and unsupported companies.

Úspory elektrické energie ve zpracovatelském průmyslu
Pešák, Jiří
This thesis features an overview of technologies that convert various forms of energy into electrical energy, and brings a description of a transmission system. Current energy situation in the Czech Republic is evaluated and views for the year 2014 are predicted. Second part of the thesis is focused on the energy evaluation of the manufacturing enterprise model. On the basis of all the information obtained, possible measures to reduce the final electricity consumption of the factory are suggested.

Energy intensity process to save grass silage volume bags
ONDRÁČEK, Vojtěch
The aim of this work was to measure and evaluate the energy intensity of grass silage during storage in bulk bags. The values were measured on a line consisting of tractor and ma-chinery for storing forage. Further information was obtained from the service line. The results were over-straightened with technical and technological norms for agricultural production and other ways of storing silage.
