Energy assessment of buildings
Velísková, Eva ; Maurerová, Lenka (referee) ; Hirš, Jiří (advisor)
The master’s thesis deals with energy assessment of buildings according to a current valid legislature. In the first part the energy assessments problems are solved. The next part solves the energy concept of the educational building, Pavilion P4, AdMaS centre of Faculty of Civil Engineering of BUT, in the form of project documentation. In the part of thesis there is a simulation characterizing dynamic behavior of building. The thesis point is the evaluation of energy balance and a draft of measures leading to the power consumption decrease.

Designing of a hot water heater
Zdražil, Pavel ; Frömel, Zdeněk (referee) ; Baláš, Marek (advisor)
This thesis processes design of hot water heater. It was done thermal, hydraulic and basic strength calculations in the work and from their outcomes was set up a design of heat exchanger, which was afterwards modelled and drawn. In the beginning of the work is reader introduced to heat exchanger types and characteristics and also to its thermal processes. Then the work continues with thermal design of the heat exchanger, where the most important outcome is heat transfer surface with other geometric parameters, followed by hydraulic design, where pressure loss on water side was calculated. The calculations are finished up by basic strength design, calculating thickness of shell and tube walls. The thesis is ended with evaluation of computed design and description of its basic features.

Assessment of three types of heat exchangers
Hlavinková, Valérie ; Toman, Filip (referee) ; Baláš, Marek (advisor)
The aim of this thesis is to assess selected three types of heat exchangers designed for emergency cooling. The theoretical part of this thesis consists of a research containing an overview of exchangers. It includes a description of the construction of exchangers, characte-ristics in terms of heat transfer and an indication of the areas of its use. The practical part deals with the thermal and hydraulic design of two tube heat exchangers and a plate heat exchanger. Finally, the evaluation of the designed exchangers is performed.

The efficiency of heat distribution
Vích, Pavel ; Horák, Petr (referee) ; Počinková, Marcela (advisor)
This diploma thesis focuses on the analysis of heat loss of heating distribution in the industrial area. The aim of this labor is to determine heat loss heat distribution kept in non manholed canal and evaluate economic return to build a local source of heat for the office building. For this building is in two variants resolve the reconstruction of the existing heating system. For the first variant is designed the local gas condensing boiler and for second variant existing central heat source. The experimental part of this labor compares the measured and calculated values of boundary conditions of hot-water pipes kept in non manholed canal.

Proposal heating system of the house
Češla, Martin ; Kracík, Petr (referee) ; Baláš, Marek (advisor)
The bachelor thesis aims to calculate the heat losses of a detached house, propose the temperature gradient and suggest the radiators for the current gas boiler as well as for a new condensation boiler. The thesis also contains the schematic drawing of the radiators in the plan view. Eventually, the thesis deals with the calculation of the radiators replacement and determinates the payback period.

Thermal properties of the window frame and the connection joints
Hejný, Lukáš ; Hraška,, Jozef (referee) ; Doc.Ing. Miloslav Bagoňa, Ph.D (referee) ; Štěpánek, Ladislav (referee) ; Kalousek, Miloš (advisor)
This thesis deals with the solution problem of fitting a window in the wall, especially for passive houses. It provides options to optimize the window connection joints, improve the thermal transmittance of the window frame, thereby reducing the total heat loss through the window. In the first part of the thesis is a research literature on the windows and heat technical and physical mechanisms. Are described equations and physical processes taking place in the windows and related building structures. This section describes the basic points in history, technical description of windows, etc. and present ways of assembly Installation the window and the influence of the thermal properties of the heat loss. The next part deals with the description of the work and the results obtained in the course of doctoral study. Describes the main objectives of the dissertation thesis, calculations and simulations of temperature fields and the results of the calculated values. Furthermore are described and analyzed measurement data and compared with the calculated values. At the end dissertation thesis are given opportunities to improve the current solution regarding the heat transfer coefficient of the frame, the optimal way of installation fillers windows in the perimeter wall and improve the thermal properties of the connecting joint.

Cost comparison of family houses with structures of thin-walled steel profiles
Pozděnová, Barbora ; Aigel, Petr (referee) ; Výskala, Miloslav (advisor)
The aim of this thesis is to find the best option of the building technology for a house. The thesis is divided into two sections – theoretical and practical. The theoretical section consists of three parts. The first part deals with theory of costs and pricing. Second part specifies types of the budgeting used in Czech Republic and the last part is focused on description of the selected construction systems used for building a house. Second section deals with description and the layout of the house, for which three budgets are set with a respect to the used option of the construction system. Furthermore, a comparison of the technical parameters as well as the costs analysis according to the TSKP is made. Finally, the optimal variant is selected with respect to the price and technical properties.

Construction details of buildings evaluation from energy demand point of view
Císař, Milan ; Šikula, Ondřej (referee) ; Adam, Pavel (advisor)
Theoretical part of Diploma thesis deals with issues about thermal bridges and thermal connections in building structures. The Calculating part focused on the family houses with a low heat use. The results of this part are energy and financial evaluations of family house. The last part deals with the using of computer technology in engineering practice. These chapters devote about computer modeling an assembly details of passive house and family house after reconstruction (the dates of family house after reconstruction are compared with the results from experimental measurements). The last section of this Diploma thesis solves dynamic modelling of particular passive house in simulation program called Trnsys.
