The technique of intelligent buildings
Bojanovský, Tomáš ; Charvát, Pavel (referee) ; Štětina, Josef (advisor)
The thesis provides a basic concept of intelligent building and related fields where this technology is appropriate. The next section describes the systems used in this field, especially the so-called communication buses and protocols. For an overview of developments in this area there is also a list of major companies involved in this technology. As a practical example is then described by air temperature and air control facilities in the building A2 or A5 in a building located within the Faculty of Mechanical Engineering, Brno University of Technology. For both cases are also proposed possible treatment.

HVAC simulation tools
Fiala, Tomáš ; Štětina, Josef (referee) ; Charvát, Pavel (advisor)
This bachelor thesis deals with chosen software building simulation tools for heating, ventilation and air condition: DOE-2, EnergyPlus, eQUEST, ESP-r and TRNSYS. The thesis includes basic characteristics of these programs and their main advantages and disadvantages. Next there is their comparison from application capabilities point of view.

HAM-Tools library use for the simulation of the thermal performance of the house
Zábojník, Jakub ; Charvát, Pavel (referee) ; Štětina, Josef (advisor)
In terms of master’s thesis HAM-Tools library designed for MATLAB/Simulink was modified for the use in simulations of houses in the Czech Republic. Modified library and its parts were described in detail and tested by the simulation of the one-zone and two-zones models of the house. The simulations of models with same parameters were also realized in program TRNSYS. The corresponding results achieved in mentioned simulation tools were compared to each other. The one-zone model created by using HAM-Tools library is tested by the simulation of ventilating, heating, cooling, and sources of moisture. A demonstration of the practical use of the simulation is carried out in the thesis, namely by examining the influence of the insulation thickness on the thermal performance of the house (resp. its heat loss) on real atmospheric conditions. Among others, available resources of meteorological data are mentioned and compared to each other. The function for processing of the meteorological data to a file compatible with the HAM-Tools library was created. It was also created a material data file containing commonly used materials of building structures in the Czech Republic and their parameters.

VRF system
Lackovič, Roman ; Lopušník, Petr (referee) ; Hejčík, Jiří (advisor)
Master's thesis "VRF system" aims on the energy simulation of energy needs for HVAC system of one floor of the FSI NetMe Research Centre building and followed evaluation of the advantage of using VRF system with heat recovery function. The first part is a theoretical introduction, which describes the basics of the mechanical refrigeration, following the differences and ways of functioning of the VRF system with heat recovery function. Practical part of this work is aimed on the description of the way of data input into the simulation tool. Finally, the results of the simulation and economical comparation of the VRF system and the existing four-pipe cold and warm water distribution system are presented

Design of a family house PV system with electrical energy accumulation
Murgaš, Martin ; Klimeš, Lubomír (referee) ; Jaroš, Michal (advisor)
The master thesis will concern design of hybrid photovoltaic system for a family house with accumulation of electric energy. Three alternatives of power consumption will be made. For each alternative multiple simulations will be carried out with different amount of photovoltaic panels and batteries. The most appropriate alternative and size of photovoltaic system will be chosen based on those simulations. Finally the choice of alternative will be described.

Modern methods of control of heating systems
Machala, Martin ; Weismanová, Júlia (referee) ; Štětina, Josef (advisor)
The aims of the thesis are modern methods of control of heating systems. Basic principles of regulations are explained and methods of control of heating sources and exchangers are explored. Heating system of family building is projected with two types of control – equithermal regulation with thermostatic heads and individual room control (IRC). Both variants are simulated in program TRNSYS 16.1. From the results are concluded advantages and disadvantages of examined systems of control.

Dynamics of heating surfaces behavior
Oravec, Jakub ; Gebauer, Günter (referee) ; Šikula, Ondřej (advisor)
The diploma thesis is focused on the research of dynamics of selected heating surfaces behavior. The aim of the thesis is to determine the dynamics of heating and cooling and to determine the effect of these characteristics on energy consumption of the building. The project part deals with the design of a heating solution for a residential building in three variants. An Energetic simulation is made for the designed variants, that compares the consumption of thermal energy during one year. The next simulation research the dynamics of selected large-scale heating surfaces. For each construction, nonstationary models of heating up and cooling were made, which are compared in terms of the thermal inertia.

Design solution for the control of existing buildings technologies
Neminář, Štěpán ; Drábek, Ivo (referee) ; Hejčík, Jiří (advisor)
This master´s thesis is dealing with designing wireless management system for existing buildings. In the first part there is description of topologies a communication protocols used for wireless automation. Further there are characterized some devices for lighting, heating, ventilation and cooling regulation. These are used for a model network of a building management, where is system OpenHAB also presented. In the next chapter is aprissed specific edifice and its typical operation where is also designed basic and extended solution for it. This part continues with computation of energy consumption in TRNSYS software, that are used to calculate economic return for both variants.
