Comparison of heat sources for family houses
Mužík, Jan ; Lisá, Hana (referee) ; Toman, Filip (advisor)
The bachelor thesis focuses on the comparison of different heat sources for four model houses with different heat losses. The main types of fuels used for heating the houses, such as solid fuels (biomass, fossil fuels), natural gas and electricity, their advantages and disadvantages as well as their environmental impact are presented. Subsequently, a complete overview of the available technologies in the field of heating of family houses is prepared, describing their technical parameters, operation, energy efficiency, costs and environmental impact. The thesis focuses on traditional heat sources such as solid fuel boilers, local heaters, gas and electric boilers, but also on their more modern alternatives such as gasifier boilers, automatic pellet boilers, condensing gas boilers and heat pumps. In the practical part, calculations of the total costs of heating and domestic hot water heating by each heat source of all four model houses are performed. This part is complemented by tables with technical parameters of the selected heat sources and also graphical dependencies comparing their total operating costs.

Possibilities of reducing the energy demand of a family house within the NZÚ program
Milionová, Kateřina ; Aigel, Petr (referee) ; Výskala, Miloslav (advisor)
This bachelor's thesis focuses on the energy and financial savings, which are key interests of today's society and closely linked to the measures described in this thesis. The theoretical part provides detailed explanations of the key concepts related to the topic. Subsequently, attention is given to improving the thermal-technical properties of houses and identifying technological procedures for reducing the energy demands of buildings. An important part of the theoretical part is also a description of the subsidy programme called „New Green Savings“. In the practical part of the thesis, the operating costs of the house and the costs of implementing three possible insulation measures for the envelope masonry and the window and door filling in order to improve the thermal technical properties of the building are quantified. Energy performance certificates (PENB) are prepared for both the current state of the house and one of the proposed variant. The work also includes a quantification of the subsidies that can be obtained after the implementation of the measures and a subsequent analysis that could lead to an increase in the subsidy amounts. Finally, the payback period of all investments made is calculated.

Heating options of a house
Klíma, Petr ; Elbl, Patrik (referee) ; Toman, Filip (advisor)
The bachalor‘s thesis, dealing with the possibilities of heating a family house is devided into three parts. The first part presents heat sources for houses and fuels that are used for heating. In the second part, the heat losses of already specifically selected house and the annual energy demand for heating are calculated. The third part deals with the economic evaluation of specific heat sources.

Energy savings in heating
Menšík, Marek ; Kracík, Petr (referee) ; Baláš, Marek (advisor)
This thesis deals with measures for the conservation of thermal energy required for heating the House. The work is divided into three parts. The first part is dedicated to the calculation of the heat loss of the family house. The second part deals with the possible measures for reducing heat loss. In the third part are designed for specific measures, their impact on the heat loss of the House and economic assessment. In conclusion, the best option is listed with the shortest return on investment.

Possible decrease of energy consumption in residence
Palkovič, Peter ; Baláš, Marek (referee) ; Pospíšil, Jiří (advisor)
Thesis deals with the possibility of reducing the energy costs of a typical family house located in Brno. In the first part is a detailed calculation of heat loss of the building, considering heat gain and subsequent quantification of costs for heating, hot water and total annual costs. In other sections provide specific calculation of the economics for the partial implementations of planned procedures leading to a reduction in heating costs (replacing windows, doors, facades and floor ceiling). A calculation for changing the heating method and compared to the existing boiler. A possible reduction in the energy required when using energy from the Sun. In the penultimate section briefly review the options for what you get a subsidy from the grant program "New Green Savings Programme" and reduce the initial investment. Finally the comprehensive proposals of different options exchanges boiler insulation, replacing windows and doors, and the subsequent evaluation of the best solution when investing 350 000 CZK.

Energy Evaluation of Technical Services Systems
Cap, Petr ; Horák, Petr (referee) ; Vendlová, Lucie (advisor)
This Master’s thesis deals with the energy evaluation of existing buildings sports-recreational company complex in Brušperk. For this purpose provides a comparison of selected fuels as an energy source for the heating in terms of economy and their impact on the environment. In addition, provides an overview of existing legislation for elaboration of an energy audit. To complement shows the calculation of return on investment in solar panels on the roof of one of the objects. Calculation is based on the results of performed experimental measurement. Finally, the thesis presents a comparison of energy performance of buildings simulated in the Bsim software with reality.

Heating units for family houses - algorithm for selection
Reiter, Milan ; Vondál, Jiří (referee) ; Kermes, Vít (advisor)
This bachelor’s thesis deals with the ways of heating for family houses. In the first part of this thesis are described the heat sources. The heat sources are diveded by type of fuel. In the next part of this thesis is a decription of claims for installation the heating source, the use of various fuels and chimneys. In the next part are descibed claims of an operation the heating sources. The fourth part deals with the algorithm for selecting a source of heat. Here is a description of each step of algorithm, which we need for selection of suitable heat source. In the last part of my thesis is made a presentation of the algorithm performed on a model family home. There are selected six types of heating in the house. At the end is chosen one, most economical type.

Energetical usage of phytomass for heating of buildings
JIŘÍK, Jaroslav
The bachelor thesis deals with energetical usage of phytomass for heating of buildings. The issue of biomass and energy crops were described based on available literature. The main objective was to compare Miscanthus, Phalaris arundinacea and Festuca arundinacea in terms of biomass yield, dry matter yield and the heat of combustion. Four wood pellet machines were studied in terms of energy consumption and the rate of pellet production. It was found that the annual costs of production of the required quantity of pellets (including costs of planting) for a model house built by current technologies were different by individual plants. The costs of heating using pellets of Phalaris arundinacea were 16 349 CZK per year, using Miscanthus 13 519 CZK per year and using Festuca arundinacea 9 749 CZK per year. It was concluded that to use the pellets made of Festuca arundinacea is the most advantageous possibility of heating.
