Analysis of Ceiling Heating
Carbol, Ladislav ; Plášek, Josef (referee) ; Vendlová, Lucie (advisor)
Diploma thesis deals with analysis of radiant ceiling heating in VUT dormitories. The work contains a theoretical analysis of radiant and convection heat transmission of ceiling heating. Part of this work is creation of mathematical model for evaluation of variables typical for radiant ceiling heating. Model outposts are compared with data measured on a real building.

Heat recovery in Building Services
Hrabová, Kristýna ; Plášek, Josef (referee) ; Šikula, Ondřej (advisor)
This thesis deals with the optimization of sewer heat recovery. For proper design and optimization it is necessary to use three basic methods: diagnostics, heat balance calculations and modeling. In 2D software Area Calculation are simulated different types of sewer exchangers arranged in sewer pipes. Using models of software CalA and simulations will be selected optimal variant. Using software BSim, which is based on more zone numerical simulation of the energy needs of buildings in relation to indoor climate, are detected heat needs of an office building. The optimal number of sewer exchanger is designed from the identified performance heat exchangers and supplies heat for the building.

Design of heating system of office building
Kovaľová, Silvia ; Plášek, Josef (referee) ; Horká, Lucie (advisor)
The diploma thesis aims to design a heating system in an administrative building and also to create a simulation for this building. The theoretical part describes simulation programs dealing with energy demand and monitoring the internal parameters of the inner climate. The calculation part solves the heating system's design in two heat source variants – a heat pump and a gas condensing boiler. In the last part, there is a model of the building created in WUFI Plus and the simulations are described under different input condition boundaries.

Heat transfer analysis of phase-change process in tubular exchanger
Fečer, Tomáš ; Bašta,, Jiří (referee) ; Kabele,, Karel (referee) ; Plášek, Josef (advisor)
The system HVAC is frequently based on cyclic phase change of boiling fluid. This phase change of boiling fluid (liquid-gas or gas-liquid) is coupled with boiling heat transfer by nucleate boiling, convective boiling and pre/post dryout effect. The nucleate boiling is depended on superheat of wall (i.e. heat flux) and presence of active nucleation sites. The two-phase convection boiling with dependence on mass flux and vapour quality is performed in liquid film between superheated wall and vapour core. The pre/post dryout effect is significant, when the liquid film is consumed and superheated wall is exposed directly to vapour core. This boiling heat transfer by nucleate boiling, convective boiling and pre/post dryout effect is simplified for engineering design on boiling heat transfer coefficient. Therefore, the dissertation thesis is aimed at experimental analysis of phase-change process in advanced engineering design.

Analysis of transport hub with use of simulation tools
Nikolov, Daniel ; Plášek, Josef (referee) ; Okřinová, Petra (advisor)
In 2018, the City Architect's Office prepared an idea urban design competition that outlined the direction of the overall solution of Mendl Square. The winning proposal is based on an overall change in transport organisation. The intention was therefore to plan the revitalization at the same time as the planned repair of the steam pipe, which will take place from April to September 2021. And as if fate wanted it 2021 is the anniversary of 200 years since J. G. Mendel – the founder of genetics, after whom the square is named. The aim of revitalization is to minimize the unattractiveness and dysfunction of the space. In this way, significantly change the comfortable conditions of the transfer node. The aim of this thesis is to break down critical points from the point of view of pedestrian traffic and subsequently to establish effective steps leading to their optimisation. The thesis also deals with the new Smart City field and its use for the collection of experimental data that could be used to improve input data in the creation of numerical models of public spaces.

Analysis of indoor climate and design of heating system in the church of Holy Name of Jesus in Telc
Kovaľová, Silvia ; Plášek, Josef (referee) ; Horká, Lucie (advisor)
The aim of this bachelor‘s thesis is to analyze the microclimate and to assess and design a heating system in Jesuit Church of Holy Name of Jesus in Telc. The theoretical part describes methods of analysis of the microclimate, presents examples of analysis described in scientific articles and provides basic classification of thermometers and hygrometers. The second part includes analysis of the microclimate of the church based on data measured during the observed period. Further, it contains an assessment of the current heating system and a design of an alternative solution of the heating system. The third part, which includes drawings, processes the alternative solution of the heating system and also provides a functional scheme of the actual heating system with the engineering report.

Simulation of the pedestrian evacuation from the school facility
Tesař, Martin ; Plášek, Josef (referee) ; Apeltauer, Tomáš (advisor)
The Bachelor thesis is focused on basic principles of soft targets security and on threats aimed at them. Part of this thesis is about the process of an evacuation movement modeling from a grammar school building, specifically the grammar school in Brno-Řečkovice. The model of the building has been created in the Revit program and the simulation of the movement in the Pathfinder program, which is based on agent simulation technologies. As for the methodology, the thesis is a comparison of the evacuation processes under different conditions.

Microscopic traffic simulation in urban areas
Bátora, Filip ; Plášek, Josef (referee) ; Apeltauer, Tomáš (advisor)
The main goal of my bachelor's thesis is to provide a theoretical insight on the topic of traffic modelling, as well as finding a practical solution to a specified issue. I will use the Aimsun software to create a microscopic model of a traffic junction using two different modes of traffic light signals. With the help of various methodical directions, I will provide an economical evaluation and comparation of the overall junction travel time.
