Warm-air heating and ventilating system for low-energy family house
Musil, Zdeněk ; Katolický, Jaroslav (referee) ; Jaroš, Michal (advisor)
The diploma thesis deals with warm-air heating and ventilation system of energyefficient family house. The part of thesis is theoretical introduction to low-energy and passive houses, ventilation and heating. The proposal itself is based on the applicable standards and includes all progressive steps, including the calculation of the thermal performance and sizing individual parts of the system. The drawing project documentation is listed in appendixes.

Energy performance of low-energy houses
Strava, Jan ; Štelcl, Otakar (referee) ; Baláš, Marek (advisor)
The bachelor´s thesis focuses on low-energy houses. It will prove wheter or not a house built as low-energy house really does meet requirements for this classification. Further it suggest investment options for additional reduction of energy consumption. The actual results of 10 year old building will be compared with investor´s original requests.

Impact of the architectural concept on the energy consumption of heating of the energy-saving residential buildings
Křeček, David ; Hudec, Mojmír (referee) ; Vaverka, Jiří (referee) ; Ing.arch.Lorant Krajcsovics,PhD. (referee) ; Chybík, Josef (advisor)
Human efforts to increase their comfort rise in density of population in congested city areas, rapid growth of traffic and electric smog created due to constantly transforming communication technologies all resulted in an increase of stress in the immediate human environment. All of this, along with frequent reports about changes in global climate, gradually contributes to an alteration of thinking of the whole society, which is forced to face the consequences of economic damages caused by climatic changes. If we want to tenably assert adequate economic and social living conditions, we have to approach the natural environment in a more profound way. In accordance with the trend of substantional development for the purpose of enhancement of the quality of the living environment in the field of building industry, it is logical to concentrate on buildings, which are conceptually focused on saving of the energy. That is on energy-efficient houses. Pathway to sustainable building is not based on discovering one or several multipurpose technological solutions, but on usage of new designing principles, new materials and methods of processing them as well as new techniques of construction. For an effective creation of a building concept it is essential to have that kind of device which quickly responds to changes performed on a design, enables an easier work on variants and produces the most accurate results. Consistent application of energy optimizing methods is necessary particularly for designs of energy saving houses. Beginning efficient building design is the most “abstract factor of concept linked with very uncertain inputs,” because a lot of parameters in that moment is still unknown. Many mutually connected factors are invoked during designing passive house e.g. trajectory of the sun and the shielding effect of the surroundings, the aspect of sunlight and interior lighting, power quality construction, etc. Currently, the architect has no choice, he can use only well-known precepts, such as large windows are facing the South not the North. Unfortunately this "empirical formula" for the design of a real passive house is not enough. And yet the first draft of the house is most affected by not only its shape, form, but user´s comfortable, cost, feasibility and future energy behavior of buildings and related operating costs of the house too. It is obvious that this stage should not be underestimated, because “minor variation of the initial inputs greatly influence the outcomes.” With this reasoning, the work focuses on early stage design decision, i.e. the architectural concept of a passive house (an idea, vision). Therefore the aim of this work is to simplify the issue into understandable form, i.e. the creation of relatively simple and illustrative sketches, which generalize the issue satisfactorily, show the individual parameters (glazing, shading, shape, size, etc.) and change need of heat for heating passive house. The results of the work will be useful when the architect picks up the pencil and starts to think about his future house. At this point, he will have on hand sketches, which give him an idea and streamline his further design. Therefore the main goal is to create new outcomes and identify energy behaviour of buildings with a computational tool. This research works with virtual idealized mathematical model in the software PHPP 2007 CZ and uses "phenomenon" of parametric equations and sensitivity analysis.

Efficiency analysis of green buildings operations
Muškát, Petr ; Dvorská, Michaela (referee) ; Ivanička, Koloman (advisor)
The main topic of my bachelor’s work is comparison heating costs of a family double house with original wall fillings and after applying external insulation including additional saving measures. My work is taking in count a possibility of applying for financial grant organised by European Union. This grant is called Green for savings and it is a helping tool leading to energy savings and modernization of old buildings. Next part is focused on used materials in nowadays for building revitalization and reconstructions. These materials has to meet high standards and criteria in thermo-insulation combined with simple construction solution. Manufacturers in these days tend to raise the quality of their products to maximal possible level.

Economic Assessment of the Construction of Passive and Active Houses
Ondra, Filip ; Komosná, Milada (referee) ; Hrdlička, Tomáš (advisor)
This diploma thesis examines the economics of use of technologies linked with low-energy, passive, and active house construction which is presently very often a topic of interest. The goal of the thesis is to evaluate economic effectivity of additional investment into construction materials leading to reduction of heating requirements of the evaluated family house. Furthermore, economics of the use of advanced technologies of ventilation, different heat sources and photovoltaic power plant are assessed. The result is a complex evaluation of different alternatives of the house which makes this thesis helpful in answering the question whether these additional investments will pay off.

Detached Family Residence
Staněk, Martin ; Omishore, Ayodeji (referee) ; Vajkay, František (advisor)
This bachelor thesis solves a design of two floors detached family residence with flat roof on plot 2653/1 in Havířově – Bludovicích. Design of this project solves architectural, structural and technical solution of the object according to demands of investor. Object is designed from Heluz masonry and also uses ceiling system Heluz. Main goal of this project was to create low-energy house for four-membered family.

Heat Pumps in Buildings Heating Systems
Vláčil, Martin ; Pěcha, Jiří (referee) ; Mastný, Petr (advisor)
The bachelor thesis deals with heat pumps and their use in building modern heating systems. In the first part of thesis is theory describing the principle operating of heat pumps, their types and basic components. The other part describe low-energy house and its parameters. In the last part of theory is discussed the issue of modern heating systems and types of heating elements used in it. In the practical part is the prescription of family house given by supervisor, the calculation of its heat losses and the design of the heating system. Further, the heat pump design and its economical comparison with selected heat sources.
