NetZero – carbon neutral living in Brno
Thunová, Nicola Vanesa ; Gebauer, Pavel (referee) ; Sedláček, Michal (advisor)
The diploma thesis deals with the design of an apartment block conceptually designed as a carbon-neutral building in Brno. The selected object is a continuation of the pre-diploma project PURE CITY, in which a set of buildings was designed as part of the urban study, which dealt with the issue of NET ZERO within the urban and social scale. The demarcated area is located in the cadastral area of Starý Lískovec on Jihlavská street near the new Západní Brána (West Gate) stop and not far from the campus of the Bohunice Faculty Hospital. The NET ZERO concept deals with sustainability and the effort to achieve a neutral balance of carbon footprints throughout the building's life cycle. The inner block is designed as a set of 8 housing sectors. The inner space of the park-like courtyard is used for staying and relaxing and is a completely private space for the residents of the block. The building in the corner parts reaches up to 7 above-ground floors, thus responding to the orientation to the cardinal points. In terms of shape, it prescribes a rational rectangular shape from the north side, but on the south side, the facade is slanted, as it was necessary to give way to the ongoing existing communication. The apartments are designed in several categories and mainly aim at the density of the population. The apartments are complemented by spacious balconies, and the apartments on the ground floor have terraces located at the street line, which demarcate public and private space with a double barrier and height difference. The height difference thus also responds to the descending terrain, which reaches a height difference of up to 3.5 m on the southern side. On the ground floors in direct contact with the street line, active parterres with smaller shops or services are designed, or WORK and LIVE housing units, which combine work environments, such as studios, with living space. These spaces are designed over 2 above-ground floors in the style of a loft apartment. The roof plane is designed as flat roofs in several height levels, on which are located private terraces for residential apartments, located on the highest floors, as well as community gardens for residents of the inner block, and a large part is occupied by an extensive green roof supplemented by photovoltaic panels for pumping solar energy.

On-line calculators for the design of renewable energy installations
Ondráček, David ; Pospíšil, Jiří (referee) ; Linda, Jakub (advisor)
This thesis focuses on the field of renewable energy sources (RES). It focuses on the topic of computational tools that manage the design process of a system using RES. These tools are introduced, their calculation methodology is described and then they are evaluated. As a part of this thesis there is also introduced a design of a unique calculation tool. This tool calculates the energy balance of a dwelling using solar energy and a heat pump.

Preparation and characterization of unsaturated bio-polyester resins
Žůrek, Michal ; Petrůj, Jaroslav (referee) ; Figalla, Silvestr (advisor)
The theoretical part of this work is devoted to the selection of suitable components for synthesis of a branched oligoester and their structural arrangement. Further, oligomers of lactic acid esterified with crotonic acid branched by erythritol or pentaerythritol are discussed. Crosslinking of prepared oligoesters is accomplished by free radical mechanism using vinyl acetate as reactive diluent and 2,2'-azo-bis-isobutyronitrile as initiator. Resin was cured by vinyl acetate in different mass ratios. Results show that there in an optimal ratio for curing between oligoester and reactive diluent. Using less vinyl acetate results in insufficient crosslink density or, on the contrary, using considerable excess of vinyl acetate causes rapid polymerization, that also results in lower density of crosslinking. The crosslink density was determined indirectly by extraction of the soluble part to acetone after curing and drying of the product.

Critical Analysis of EU Policy and Its Impact on Business of E.ON SE
Starostová, Andrea ; Kamenický, Oldřich (referee) ; Škapa, Stanislav (advisor)
Hlavným cieľom diplomovej práce je kriticky analyzovať politiku Európskej Únie a jej dopad na činnosť nadnárodnej spoločnosti E.ON. Keďže politika Európskej Únie má za cieľ zefektívniť spôsob podnikania vykonávaného v rámci Európskej Únie a okrem iného má predstavovať garanciu zodpovednosti jak spotrebiteľov, tak dodávateľov operujúcich na trhu, tak zámer práce bol definovaný na analýzu politického vplyvu rozhodnutí Európskej Únie a ich dopad na následné strategické rozhodnutia firmy. Analytická čas práce je preto zameraná na analýzu Európskej energetickej politiky s kladením dôrazu na profil spoločnosti E.ON, Európsku energetickú stratégiu, obnoviteľné zdroje, jadrovú energetiku, bezpečnosť energetickej dodávky a na Európsky systém obchodovania s emisiami.

Renewable energy sources in CR
Kozumplík, Ondřej ; Škvařil, Jan (referee) ; Fiedler, Jan (advisor)
The content of bachelor study is the technical recherche of the renewable resources of energy in the Czech republic. It appears here the principal, use, potential and advantages and disadvantages of each type of renewable resources - water, wind and biomass. Then the use of solar energy for photovoltaic conversion to electrical energy is described in detail. At the end of this study is described one of the many recently build photovoltaic power stations in the South Moravia territory, the solar power station in Bzenec.

Technology Power to X
Řezník, Dominik ; Baláš, Marek (referee) ; Kracík, Petr (advisor)
The bachelor thesis deals with technologies for the electricity storage based on its conversion into another form of energy ("Power to X"). It considers the possibility of their use for the storage of electricity generated by renewable energy sources, which should gradually replace conventional electricity production in coal-fired power plants. The first chapter of the thesis is devoted to the current and possible future state of the electricity sector in the Czech Republic and a description of selected electricity generation technologies. The second chapter contains a classification and description of technologies suitable for electricity storage – their functional principles, advantages and disadvantages or e.g. possibilities of further use of products obtained by means of conversions are included. In the third chapter, selected parameters of these technologies are illustratively compared in created graphs, each containing two parameters. The results of the comparison are then continuously discussed.

Analysis of the influence of thermal effects on thermophotovoltaic system
Kolář, Jakub ; Vyroubal, Petr (referee) ; Šimonová, Lucie (advisor)
This semestral thesis focuses on the description of specific renewable resources in the form of thermophotovoltaic cells using selective radiators with micro/nano structures. This work deals with an introduction of renewable resources and specifically focuses on thermophotovoltaic. Thesis describes basic principles, but also influences affecting the proper functioning of these systems. It also focuses on selective radiators, which are created by mikro/nano structures, and factors that can affect their implementation or simulation. Part of the work are also examples of calculations of basic parameters of the structures, which will be used in the simulations. Next chapters are dealing with simulations which are analyzing thermal effects on termophotovoltaic system. Except the analysis itself there is also partial optimalization solving some of the negative thermal effects.
