Design of urban area using advanced technologies
Špaček, Jan ; Apeltauer, Tomáš (referee) ; Remeš, Josef (advisor)
This thesis focuses on the design of urban areas in regards of the air flow and the creation of Urban Heat Islands. It reviews basic aspects influencing the design of streets. Every building, tree, or obstacle obstructs the air flow and creates the wind shadow, where the air pollution increases. It also creates areas of higher wind speed, in which public comfort is reduced. By understanding the importance of this process and by implementing it into the urban planning process, using advanced technology we can create healthy urban environment.

Evaluation System of Thermal Condition Environment and his Measurement Uncertainties Analyze
Košíková, Jana ; Němeček, Pavel (referee) ; Kureková, Eva (referee) ; Vdoleček, František (advisor)
The Ph.D. thesis deals with the evaluation of indoor thermal environment in which people are located. A great attention is paid to the thermal comfort. If a person in a given environment does not feel well, then makes mistakes. Thermal comfort is created many parameters that can be monitored and managed. These parameters include not only temperature but also other parameters such as the mean radiant temperature, operative temperature, humidity and air velocity and the draft. All these parameters can be measured. The standard ČSN EN ISO 7726 is written how and what the parameters are measured. Furthermore, this standard provides requirements for measuring equipment. There are many professional measuring devices. Unfortunately, these devices are very expensive. Therefore are within the project GACR 101/09/H050 - Research on energy- saving equipment to achieve the quality of the indoor environment at our faculty developed sensors for thermal comfort, which have showed comparable accuracy measurements as a professional , but it will be cheaper than professional. Knowledge of real parameters of the developed sensor thermal comfort environment is important, as with any other measurement devices, and also need to verified whether it has the required accuracy. In order to objectively sensors testing were developed two chambers - the testing and calibration chamber. The developed sensors were tested both in the open laboratory, and also in the test chamber. Then uncertainties measurement were calculated from the results of measurements This work deals with the evaluation of thermal comfort, the measurement of parameters of thermal environment, the evaluating the results of measurements and determining the measurement uncertainty of the sensors. In this thesis, based on these results, were recommended suitable sensors for measuring various parameters environment.

Aircondition of schools gym
Sotolář, Lukáš ; Uher, Pavel (referee) ; Rubinová, Olga (advisor)
The thesis is devided to three parts. The first part is the theoretical part. The theoreti-cal part deals with the heat load of buildings, which also include buildings with a ge-neral location. The second part is the computational part. The computational part is focused on heating, ventilating and air conditioning (HVAC) of the gym. The last part of the thesis is the design part.

Analysis of the meteorological dates
Králík, Martin ; Čmiel, Vratislav (referee) ; Rozman, Jiří (advisor)
The aim of the bachelor’s thesis is to recognize the basics of atmospherical physics, the techniques and measuring instruments used in weather stations and the statistical analysis of three chosen meteorological parameters. Data analysis is made by using graphical display method, which is discussed later on.

Datalogger
Štupák, Branislav ; Bejček, Ludvík (referee) ; Beneš, Petr (advisor)
The bachelor thesis deals with the datalogger development for monitoring roof constructions ambients of historical buildings. The device is made of microcontroller ATmega328P and is using simple principles of environment monitoring. The device saves measured data to SD card from air temperature, air humidity, light intensity, wood moisture and air flow sensors. In conclusion of the thesis are then succesfully tested and summarized the properties of designed datalogger’s sensors.

Analysis of bank ventilation
Grbál, Jakub ; Rubinová, Olga (referee) ; Uher, Pavel (advisor)
The aim of the diploma thesis is the simulation of different types of air conditioners using the CFD methods. The main goal of this thesis is to design the most suitable type of air conditioning in the consideration room, due to the air flow rate in the residental area. The conclusion of the work is to devote the design of air conditioning system with the application of selected type of air conditioning based on the results of CFD simulations.

Building services of near zero energy bulildings
Fikejsl, Tomáš ; Komínek, Petr (referee) ; Hirš, Jiří (advisor)
The thesis deals with the issue will be nearly zero energy. The theoretical part is divided into several chapters. Describes the requirements of applicable legislation of the Czech Republic and the EU and the application of renewable energy in these buildings. The third and last part serves as a basis for part of the experiment. Calculation section applies theoretical knowledge into practice. The subject has become a new residential building in which they are designed to ensure the technical equipment required internal environment. The proposal concerns the heating, ventilation, cooling, domestic hot water and lighting. At the end are attached graphic of energy performance certificates (PENB) and evaluated the economic and ecological point of view. The experiment deals with the measurement of the internal microclimate administrative building type in Brno, with regard to the requirements of current legislation of the Czech Republic.

The Effect of the Bypass Factor on Design and Geometry of the Evaporator for the Cooling Unit
Vytasil, Michal ; Rubinová, Olga (referee) ; Rubina, Aleš (advisor)
Diploma thesis focuses on effect of the bypass factor on design and geometry of the evaporator for the cooling unit of data centre. Effect of the bypass factor on individual design parameters is solved in detail. All dependendecies are captured by using graphs in which s placed a cement on that parameter. In part C, mathematical and physical solutions are demonstrated calculations and processes leading to the design of the exchanger. In the end, evaluation of the calculations is done and there is also showed possible improvements for the practise.
