The Swimming cetrum Brno Zidenice
Pleva, František ; ing.arch. Lukáš Ležatka, Ph.D (referee) ; Pavlovský, Tomáš (advisor) ; Petříček, Tomáš (advisor)
The main theme of this project is a concept of the Swimming centrer in Brno—Židenice. The plot in question is extremely complex. It is located on the edge of a hillside near the Health center at Viniční, which naturally dominates the area by the shape and size of its structure. The underlying idea was to use orthogonal shapes to create a building, that would not compete with the Health center but would add up to its surroundings instead. Every single part of the project was designed to delicately fit into given terrain and surroundings. Most of the functions of the building are set on the 1st floor (e.g. locker rooms, two bars, water world and wellness). The 1st underground floor features technical services rooms. On the 2nd floor, there is only a swimming pool and a terrace with whirlpools on one part of the roof. The roof top offers an excellent view on the city of Brno. South and west facades of the pool hall are made completely out of glass. It is covered by vertical curved aluminum lamellar system. That is because of the thermal technical requirements of the building, however, it is also a dynamic piece of the facade that adds up to aesthetic finish of the building. The construction is based on a combined system of monolithic reinforced concrete columns and walls and glue laminated timber beams and frames. The roofs are compact and green. In the part above the locker rooms is intense green roof planted intensively green fully-grown greenery.

Algorithm for Calculation of Radiation View Factors
Bílek, Tomáš ; Hlavička, Rudolf (referee) ; Čermák, Libor (advisor)
This thesis deals with a calculation of radiation view factors. The thesis includes mathematical model of the problem and its numerical solution. The main aim of the thesis is the creation of an algorithm for calculation of radiation view factors for given 3D geometries and its application for the heat flux analysis. CAD models of geometries, specified by a NASTRAN file format, are used as an input of the algorithm. Matrix of radiation view factors serves then as an output of the algorithm. The algorithm is programmed in MATLAB, but STAR-CCM+ is used for the NASTRAN specification of separate models. The algorithm is also designed for a computation on a computer cluster for cases of intricate geometries with consideration of shading areas.

Henzelová, Iveta ; Vymazal, Tomáš (referee) ; Hobst, Leonard (advisor)
The thesis focuses on the analysis and evaluation of the potential risks in the design and implementation of shielding structures against the effects of ionizing radiation. The rocedure of calculation and design optimization, according to the current wording of the Atomic Act and related regulations, is mentioned only marginally. According to DIN EN 31010: 2011 Risk Management - Risk Assessment Technique risk assessment were made by risk analysis. risk analysis. Risk management identified these methods - Analysis of the Causes and Consequences (Ishikawa diagram), Analysis Failure Mode and Effects (FMEA) and the Pareto diagram. These methods are implemented to identify and evaluate the associated risks. Based on the identification and assessment of these risks, appropriate measures are then proposed to reduce their impact.

The effects of ionizing radiation on semiconductor devices properties
Yermalayeva, Darya ; Šteffan, Pavel (referee) ; Musil, Vladislav (advisor)
This master’s thesis deals with the problematics of influence of ionizing radiation on semiconductor devices and their properties. The aim of the thesis is to analyze the different types of radiation that can occur in the areas of application of these components. In the second part, the degradation processes are explored, with emphasis on the influence caused by the radiation dose. Also, the displacement damage and SEE effects are described, but just slightly, because they are not part of this work. The third part describes the device design process and harmful effects, that have to be considered during the design phase. In the forth and the fifth parts of this work were done modeling of radiation effects (influence of dose rate, Single-Event Upset and Total Ionizing Dose) in PSpice program and was carried out the possibility of designing a simple dosimeter with silicon diode. In conclusion, the results of the thesis are summarized and evaluated.

The systems of building services in immovable heritage
Maurerová, Lenka ; Vlček, Milan (referee) ; Kabele,, Karel (referee) ; Doc.Ing. Martina Peřinková, Ph.D (referee) ; Hirš, Jiří (advisor)
The present PhD. thesis deals with the systems of building services (namely heating, ventilating and air conditioning, shading) which provide required indoor microclimate inside the immovable heritage. The work thus combines the exclusively technical field of building services (BS) and the general principles of heritage conservation. The aim of my PhD. thesis is the analysis of immovable heritage conservation processes, focusing on the current state of research and BS systems documentation. Furthermore the work concerns the possibilities of temporary measurements of indoor climate parameters inside the immovable heritage, and aims to develop a computer model (in BSim software) for the simulation of various working conditions in the selected buildings. For the stated aims were selected three representative historic houses: historical assembly hall at the Faculty of Civil Engineering, Brno University of Technology; the Palm Greenhouse at Lednice Chateau in Moravia; and Villa Tugendhat in Brno. These buildings had been surveyed for several years, and in this PhD. thesis I present their analysis, evaluation, and conclusions. The aims of this PhD. thesis broadly correspond to the transnational objectives. The present research is, for example, in accordance with the international document ICOMOS Charter (Zimbabwe, 2013) which is concerned with the analysis, conservation, and restoration of architectural heritage. The research of immovable heritage is also supported by European Union, e.g. by the Seventh Framework Programme of EU.

Jechová, Marie ; Krupica, Roman (referee) ; Bantová, Sylva (advisor)
The thesis titled "The indoor Environment of Kindergartens in Terms of Building Physics Requirements" addresses the challenges associated with ensuring thermal comfort in the indoor environment, while simultaneously providing adequate lighting and daylighting for the classrooms of kindergartens. The thesis is structured into interconnected and complementary sections. The first section dissects the identified problem, establishes legislative requirements, outlines research methods, and defines the objectives, which will be assessed in the conclusion. This section also includes the definition of the kindergarten object in accordance with current legislation. Furthermore, the issues of lighting and daylighting are explained from the perspective of applicable laws, regulations, and standards, incorporating all necessary variables, graphs, formulas, calculations, and definitions. Similarly, subsequent chapters will elaborate on the thermal comfort of the indoor environment. The final section of the theory provides an overview of simulation and computational software tools, employed to model different scenarios, compare the current and proposed conditions, and draw conclusions for the thesis. The practical section follows, focusing on the design of window openings, shading methods, and ventilation regimes to meet the requirements for daily lighting and daylighting while adhering to the maximum indoor air temperature in line with normative requirements. Experimental measurements of essential input data for assessing the thermal stability of the indoor environment were conducted during summer months in the existing facility. In the concluding part of the thesis, conclusions will be drawn regarding the ratio of floor area of transparent parts of building envelopes to the floor area of the classrooms. This is done to ensure compliance with legislative requirements concerning both thermal and lighting comfort in the indoor environment. The conclusion also summarizes potential measures to achieve the desired parameters and outlines a prospective solution to the addressed issues.

Tůmová, Eliška ; Gebauer, Günter (referee) ; Šikula, Ondřej (advisor)
This diploma thesis deals with the optimization of microclimate of an industrial building. There is required constant temperature with minimal fluctuations during manufacturing process in the building. Due to insufficient cooling power of air-conditioning system was objective to design a solution that ensures stability of internal temperature during production especially in summer and simultaneously should be the solution economically acceptable. Simulation shows original state defined problems. Some new or unusual materials for solar shading are reviewed in the thesis by the experimental measurements and by the comparative method. To each material is assigned shading coefficient according to Czech standards, thereby is achieved universality for calculations of heat gains resulting from solar radiation. By one part of the experiments and their evaluation is determined thickness of the standard single glass glazing. It is also determined proportional transmittance of solar radiation for certain multiwall polycarbonates, which are currently used as fillers of industrial skylights and production hall‘s window openings. From experiments resulting design is subjected to the simulation. Comparison of temperatures is shown for the time before the installation of designed solar shading and after the installation of the solar shading.
