Fotovoltaics systems for block of flats
Krška, Lukáš ; Charvát, Pavel (referee) ; Hejčík, Jiří (advisor)
The aim of this work is identification with photovoltaic systems for a panel building and finding a solution how to apply it. The work deals with history of photovoltaics, focuses on natural conditions in the Czech Republic and a briefly describes particular components which photovoltaic system consists of. The panel building is divided into parts were is possible to use the system and further is in detail described the Evalon-Solar product which is optimal to use on flat roofs of panel buildings.

Family house energy requirements audit
Halata, Maxmilián ; Hejčík, Jiří (referee) ; Fišer, Jan (advisor)
The bachelor’s thesis is focused to possibilities of using National calculating tool of buildings energy requirements according to Czech government regulation no. 148/2007 Sb. The tool was applied to calculate energy requirements of chosen family house. Several types of house modifications which can reduce energy requirements are proposed based on results of the audit. Each modification of the house is analyzed from the energetic, construction and economic point of view.

Ventilation strategies for block of flats
Tuka, Ján ; Krejčí, Vladimír (referee) ; Hejčík, Jiří (advisor)
This bachelor´s thesis contains a summary of ventilation strategies used for ventilation of block of flats. In the beginning, it includes the list of most common harmful substances which might occur in this space. Next chapters present principles and purpose of ventilation, types of ventilation, characteristics. The principles of self-ventilation and forced air ventilation are described here, the ventilation systems based on these principles and advantages and disadvantages of these systems are mentioned. Also the minimum requirements of ventilation for living space are specified.

Ventilation and air conditioning of a car cabine
Viščor, Petr ; Hejčík, Jiří (referee) ; Fišer, Jan (advisor)
In this work are described kinds and functions of air-conditioning systems which are used in cars. Further is described heat transfer between car cabin and ambient environment and issue of reduction of air-conditioning energy consumption. Last part of the work contains numerical simulation made by the THESEUS-FE 2.1 software package. This simulation was done on a model of the Toyota Prius car and was focused on effect of glazing on a temperature of the air inside the car cabin during hot summer days.
