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.

Low energy detached house
Drlík, Tomáš ; Hudec, Mojmír (referee) ; Sedlák, Jiří (advisor)
The thesis deals with a project documentation of a low energy house for family of up to six persons. The house is located at the foothills of Jeseníky mountains. The object is designed as a two-storey building, with a cellar, standing in a sloping ground. There is a saddle roof. The south facade is roofed, glassed terrace. The nord shelter protect the house from the effects of weather.

Low-energy semidetached family house
Štefanik, Jan ; Hudec, Mojmír (referee) ; Sedlák, Jiří (advisor)
The bachelor´s thesis deals with the processing of project documentation low-energy semidetached family house in Panenská Rozsíčka vilage. The project as well as the addenda are aleboreted wit regard to contemporary, legislature and standards. The family house is situated on a plot of 2510/16 in the cadastral Panenská Rozsíčka. The family house is designed as a single storey building with not basement, roof bow and attic. Dimensions of the house are 13,15 x 11,4m. The roof of the house is designed bow roof. The building is designed from the systém Porotherm. The base structure consists of a plain concrete C 20/25 and steel-concrete of 150mm is concrete C 20/25 and steel B500.

Vitality in the architectonic environment
Eyer, David ; Horáček, Martin (referee) ; Hudec, Mojmír (referee) ; Kyselka, Mojmír (referee) ; Žabičková, Ivana (advisor)
More and more research studies are being conducted on the quality of architectural space as a factor affecting our mental, social and physical health. In the past, this topic was often overlooked in its complexity. The establishment of the specialized fields of building biology, biophilic architecture and the works of Christopher Alexander and Nikos Salingaros now allow us to consider various facets of this subject. This dissertation aims to analyse the topic of vitality in architectural space by studying the abilities and perceptions of its users. Therefore its aim is not to develop a new theory of “vitality-enhancing architectural space”, but to describe how this phenomenon is perceived by the users themselves. Users can provide feedback on which features of architectural space they see as the most important for the feeling of vitality. These features have been hierarchically organized based on their perceived importance, analysed and described in detail to allow their relatively easy application in practice. This dissertation will also allow a comparison with other existing works on the studied topic.

Nursery school in passive standard
Výtisk, Jiří ; Hudec, Mojmír (referee) ; Sedlák, Jiří (advisor)
Subject of this diploma thesis is a new building of nursery school in passive standards. The school has two floors. On both floors there are build two classes, each for twenty children. Structure is based on strip foundations and load-bearing walls are made from sand-lime blocks. The horizontal load-bearing structures are from cast-in-place reinforced concrete. School has green flat roof and above atrium has sloped roof. The shape of building is made by three circle segments with different radius. Ventilation of the building is ensured by heat recovery ventilation unit. Project is situated into an urban area of Brno, nearby the city center, on brownfield plot.

Energy active house
Drlík, Tomáš ; Hudec, Mojmír (referee) ; Sedlák, Jiří (advisor)
The aim of the thesis was to design an energy efficient system that uses a waste heat from the operation of distillery and helps to reach energetically active status (in conjunction with the newly designed photovoltaic panels, controlled ventilation with heat recovery and with proper design and material solution) to the newly created housing units. The need of heating is covered by using of waste heat and in the mode of economical (energy saving) operation of households, the photovoltaic panels on the surface produce more electricity than the households consume themselves.
