Analysis of operating data from the student centre at the Faculty of Information Technologies
Suchá, Petra ; Jaroš, Michal (referee) ; Charvát, Pavel (advisor)
This diploma thesis is dedicated to the analysis of operating data from the Brewery, a former industrial building, which has been reconstructed to a student centre of the Faculty of Information Technologies. The main goal of the work was to analyze the performance of the building and to evaluate energy savings originating from the energy saving measures that were applied during the retrofit.. The first part of the thesis focuses on the particular energy saving measures and the predictions of energy savings. The second part presents the results of the monitoring of the building and the HVAC systems during the first year of the operation of the Brewery.

Potential of waste heat recuperation in a polyfunctional building
Nagorskyi, Bogdan ; Charvát, Pavel (referee) ; Hejčík, Jiří (advisor)
The thesis deals with the possibilities of heat recovery in air ventilation systems. After a thorough analysis of the problems, the different ways of ventilation with the return of heat are compared even during simultaneous operation of the heating source. The research includes the selection of a suitable ventilation device with heat recovery based on a first investment and operating costs. Subsequently, the selected ventilation device is used for the HVAC project in the housing part of the multifunctional building. The project is created in BIM Revit software.

Mathematical optimization of a solar photovoltaic system for a single-family detached home
Bah, Sheikh Omar ; Mauder, Tomáš (referee) ; Charvát, Pavel (advisor)
This paper presents a mathematical sizing algorithms of a grid-connected photovoltaic-battery system for a residential house. The objective is to minimize the total storage capacity with cost of electricity. The proposed methodology is based on a Linear and Non-linear programming. We have presents results from a existing PV panel FS-4115-3 for the given climatic conditions and the electricity use profile. Measurements for whole household electricity consumption have been obtained over a period of two months. They were all obtained at one hour interval. The algorithm jointly optimizes the sizes of the photovoltaic and the battery systems by adjusting the battery charge and discharge cycles according to the availability of solar resource and a time-of-use tariff structure for electricity. The results show that jointly optimizing the sizing of battery and photovoltaic systems can significantly reduce electricity imports and the cost of electricity for the household.

Hybrid ventilation in buildings
Havlíček, Jan ; Pešek, Martin (referee) ; Charvát, Pavel (advisor)
This bachelor thesis deals with hybrid ventilation in buildings. The first part of the thesis discusses ventilation, the classification of ventilation and then natural and mechanical ventilation are summarized. The second part focuses on hybrid ventilation. Here the classification of hybrid ventilation, 2 examples of hybrid ventilation in non-residential premises and 4 hybrid ventilation systems for 4 climate zones are mentioned.

Heating curve calculation
Štěpánek, Jindřich ; Charvát, Pavel (referee) ; Hejčík, Jiří (advisor)
The bachelor thesis examines the question of heating, more precisely heating depending on climatic conditions of the environment in which the heated entity is situated. It summarizes the information necessary for calculating equithermal dependency as well as the information about the types of heat loss of buildings and their calculation. There is also basic information about the heating elements, their types and characteristics. Using all the information, a model calculation of one point weather compensation curve for the chosen reference room is determined. Further, another way how to get the heating curve is mentioned there, its model calculation is done and the advantages and disadvantages of this method are described.

Air-conditioning system of a typical floor of A1 building
Pekárek, Antonín ; Charvát, Pavel (referee) ; Krejčí, Vladimír (advisor)
Master thesis deals with designing of air-conditioning system into newly reconstructed high-rise building of Faculty of Mechanical Engineering Brno University of Technology. Reconstruction of a building results in change of thermo-technical parameters which impacts dimensioning of air condition system. Designing air-conditioning system depends on heat loss and heat gain calculation and also on consequential psychometrical calculations. The size of air conditioning equipment which provides required internal microclimate will be determined from the calculation results. Currently there is Detail design elaborated including technical report and material specification.

Assessment of thermal comfort in buildings
Procházka, Aleš ; Pokorný, Jan (referee) ; Charvát, Pavel (advisor)
This bachelor thesis summarises knowleges about methods used for assessments of thermal comfort in buldings. In opening part of thesis is thermal comfort introduces as important part of overall satisfaction with indoor environment. There are also described fyziological basics and ways of thermoregulation and individual elements of thermal balance. Next part of thesis is focused on thermal and humidity factors of indoor environment. Some combinations of these factors form thermal comfort. Main part of thesis describes methods of assesments of thermal comfort using PMV and PPD indices. For practical uses there are examples of comfort diagrams, which are based on PMV index, Thermal Comfort Meter and Thermal Manikin. Last part contains description of some instruments for measurement of used physical values.

The Earthship concept and its energy design
Peciarová, Michaela Mária ; Charvát, Pavel (referee) ; Mauder, Tomáš (advisor)
Táto práca popisuje koncept Zemelode ako sebestačný, udržateľný solárny pasívny dom a taktiež poskytuje podrobný opis energetických systémov v Zemelodi. Práca sa tiež snaží určiť energetický potenciál konceptu Zemelode pomocou odhadu energetickej bilancie daného obydlia. Celkový prehľad ideológie Zemelode a detailný opis energetický systémov, ktoré predstavujú tému čitateľovi, boli získané z publikácii rešeršom. Energetický výkon tejto stavby bol vyhodnotený podľa českých a európskych noriem pomocou výpočtu tepelných ziskov a strát pre zvolený model Zemelode. Následne, boli skontrolované kritéria pasívneho domu. Výhody a nevýhody tohto konceptu boli kriticky zhodnotené na základe rešeršu a výpočtu energetickej bilancie. Zhodnotenie výkonu zvoleného modelu Zemelode ukazuje, že toto obydlie nespĺňa požiadavky pasívneho domu, avšak stále sa jedná o nízko-energetický dom. Vykonaný rešerš ukazuje, že tento dizajn je vysoko závislý od podnebia a ročného obdobia, preto nemusí fungovať všade vo svete.
