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.

Utilization of solar energy for heating and ventilation – warm-air systems
Pospíšil, David ; Fišer, Jan (referee) ; Jaroš, Michal (advisor)
Bachelor’s thesis considers summary of application trends with using warm-air systems to space heating and ventilation. Thesis is divided into several sections. The introduction to the topic presents basic facts about solar energy; the origin of it and its availability. The next part defines systems working with solar energy for space heating and ventilation, describes partition of these systems and explains working principles. The final part gives examples in system’s application.

Study of the cooling system of a building with regard to climate change in the Czech Republic
Vašulka, Tomáš ; Charvát, Pavel (referee) ; Fišer, Jan (advisor)
The diploma thesis aims to prepare a study of the cooling system of a multifunctional building with regard to climate change predicted until the middle of the 21st century. The work includes determining the heat load of refrigerated rooms and designing measures to reduce heat gains in the summer. Diploma thesis includes design of a cooling system with fan-coil units as end appliances with the necessary hydraulic calculations. A single-stage absorption cooling unit is used as the considered cooling source, to which a free cooling heat exchanger is assigned. The design of the cooling source includes the necessary hydraulic calculations and dimensioning of the system ensuring its functional operation. Part of the diploma thesis is drawing documentation of cooling technology and connection of fan-coil units.

Accumulation of energy from renewable sources
Charvátová, Marie ; Bajko, Jaroslav (referee) ; Fišer, Jan (advisor)
This bachelor’s thesis deals with the issue of accumulation of energy from renewable sources with a closer focus on electricity storage in the "small/home" scale. Delivering energy from renewable sources is highly variable and, in order to cover the time shift between production and consumption, energy must be stored. In the paper are described individual types of energy used in residential housing, sources of renewable energy are presented and various ways of energy accumulation are analyzed. The greatest attention is paid to chemical accumulators, because they are the most suitable solution for home use due to their practicality. At the end of the thesis, operational data from a small demonstration photovoltaic power plant with accumulation of electric energy in chemical accumulators are processed and evaluated.

Parametric Study of Air Heat Exchanger
Podola, David ; Volavý, Jaroslav (referee) ; Fišer, Jan (advisor)
This diploma thesis deals with the impact of changes in operating and geometrical parameters of regenerative heat exchanger on the efficiency of decentralized ventilation units with heat recovery. Decentralized ventilation unit can be used for ventilation of family houses or smaller administration buildings. Output of this work is to determine the efficiency of a particular produced model of decentralized ventilation unit and overview of the possibilities increased efficiency of heat recovery of this units.

Ventilation of low-energy houses
Kubisz, Pavel ; Fišer, Jan (referee) ; Charvát, Pavel (advisor)
Dissertation deals with division and description progressive trends of ventilation of low-energy houses. Forasmuch as ventilation is participant in total heat consumption, It is here practical example how total heat consumption depend on ventilation heat consumption and heat consumption by construction. At the close is showed when is good, or bad, to use ventilation with recuperation.

Energy retrofitting of a family home to the nearly zero energy building
Uhlíř, David ; Fišer, Jan (referee) ; Charvát, Pavel (advisor)
The diploma thesis is devoted to reducing the energy intensity of a two-storey family house from the 1960s, to a building with almost zero energy consumption. First, the family house is analyzed in terms of the condition before reconstruction. The result of this analysis is a certificate of energy performance of the building in its original condition. Within the individual chapters, I subsequently propose specific energy saving measures. At the end of each chapter, these measures are economically evaluated using the New Green Savings Grant Program. The first measure is dedicated to improving the thermal technical properties of the building envelope. This is ensured by the complex insulation of the family house and the replacement of the original windows and doors. The second measure is devoted to the design of a suitable method of forced ventilation with heat recovery. As part of the third measure, I assess and select a suitable heat source that will replace the original heat source of the family house. As a final measure, I propose the use of a renewable energy source in the form of a photovoltaic system, which is based on energy simulation in the program DEKSOFT FVE. At the end of my work, I am developing a building energy performance certificate, which assesses the fulfillment of the condition of a building with almost zero energy consumption.

Ventilation and cooling system for an apartment in block of flats
Uřičář, Filip ; Fišer, Jan (referee) ; Hejčík, Jiří (advisor)
This Master’s Thesis deals with the design of ventilation and cooling of an under roof flat in a tenement building, built in the 1980s, and consists of five main parts. Within the first main part, the thesis is dedicated to the research of the current state of knowledge in the area ofventilation and cooling of residential premises, secondly, there is a detailed description of a particular flat, thirdly, the calculation for the optimal design of ventilation and cooling are made and, in the fourth part, suggested solutions are proposed with the following evaluation of them including the overall summary. The design of ventilation and cooling was carried out according to the design procedures with respect to the relevant standards and optimized to achieve the desired effect with respect to the requirements of the owner of a housing unit. As a solution, the ventilation of a flat by the Jablotron Futura´s ventilating unit and three variants of a flat cooling were proposed. After the evaluation of all cooling variants, the Sinclair´s multisplit system of cooling was chosen as the most suitable one.
