Possibilities of energy savings in the residential house Merhautova
Bartek, Čeněk ; Kalánek, Jiří (referee) ; Ostrý, Milan (advisor)
The diploma thesis is about the reduction of the energy intensity of the existing residential house Merhautova. The design documentation is focused on the thermal insulation of the living area, the replacement of windows and doors according to the variant of the design, accessible entrance to the house, loggia on the south side of the building and the replacement of the roofing. At the beginning of the diploma thesis the experimental part of the thermography was performed. Images of the existing object by the thermal camera were taken and building survey for the design documentation of the current state of the building was performed. Within the theoretical calculations the energy performance certificate was processed in options of the entering the thermal bridges. The energy performance certificate with thermal bridges calculated according to the details was compared with the energy performance certificate with estimated thermal bridges. A comparison of two options of the replacement of windows and doors was made in realation of the energy intesity of the building. A preliminary budget of these two options was also calculated with regard to the expected simple return on investment due to the heat saving.

Study of energy consumption reduction of block of flats
Svoboda, Lukáš ; Šteffek, Libor (referee) ; Ostrý, Milan (advisor)
The goal of the thesis is firstly to get all the information about the initial state of solved block of flats, which is located on the street Merhautova 76/954 in Brno – Černá pole, in terms of constructions, energy consumption and initial state of heating system. In the second part of the thesis, where are discussed the possibilities of reduction of energy consumption, variant drafts of reduction of energy consumption and their financial costs and the choice of optimal variant. Third part deals with assement of solved block of flats in terms of sustainable built environment by using tool to rate buildings in terms of sustainable built environment - SBToolCZ, evaluation of possibility to use renewables. In the end are written summaries and recommendations.

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.

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.

Energeticky nezávislá mobilní buňka
Sezima, Petr
The task of this diploma thesis is to design a basic unit of a living house - container, which will be suitable by its proportions to be transported easily on the roads and at the same time it will meet the requirements of a thermal protection of a building. Other complementary units are designed to the basic container to extend a house space with new rooms. There have been designed four options, for which the author calculated heat loss coefficients and defined energy ambition grade of building. For the basic unit the calculations are made for two grades of a thermal isolation. For an exact definition of these results, linear thermal bridges were calculated. Methodical process of construction composition assessment and a process of heat loss coefficients calculating are made regarding a standard ČSN 73 0540 Thermal protection of a building. Energy ambition grade of building is defined according to a public notice n.78/2013 about energy ambition grade from 22th March. According to a standard ČSN EN 12 831 there have been planned a heating load for every individual room.

Tepelně technické posouzení novostavby rodinného domu
Kunert, Martin
The thesis deals with the issue of thermal-technical assessment of new building of family house which is going to be built in the near future, based on provided documentation. Considering the building system, it is a wooden house, which is going to be realized through a "balloon frame" method. The goal of this thesis is to propose suitable composition of individual constructions, to asses them and to develop basic construction details of them which will be evaluated based on internal surface temperature and linear thermal transmission. Based on intermediate results the thermal loss of the family house will be calculated which is a crucial input for proposal of the heating system. Another part focuses on proposing of controlled ventilation system and creating energy performance certificates of the building.
