Single-family house
Diblík, David ; Nespěšný, Ondřej (referee) ; Bečkovský, David (advisor)
The subject of this bachelor's thesis is the design of a new family house built from large-scale, multi-layered CLT panels, and the preparation of project documentation for the construction phase. The building is situated on a gently sloping site in the village of Račice near Dlouhé (Žďár nad Sázavou district). The concept and design respect the surrounding development and all mandatory municipal documents, particularly the zoning plan. The building consists of a single apartment, which, through its layout and material characteristics, corresponds with current technologies and elements in construction. On the ground floor, there is an entrance hall with a separate WC, a utility room, a living room with a kitchenette, and a bedroom with a separate dressing room leading to a private bathroom. The second floor is designed with two rooms each with its own dressing room, a study, and a shared bathroom. The family house is founded on strip foundations made of plain concrete, with vertical load-bearing and non-load-bearing elements made from massive wooden CLT panels. The exterior features include contact insulation using wood fiber insulation with façade plaster or ventilated wooden cladding. Horizontal load-bearing structures, such as the ceiling and flat roof with a waterproof membrane weighted down with washed river gravel, are constructed as ribbed ceilings with a limestone screed. The second floor is roofed with a gabled roof covered with aluminum standing seam panels, designed to accommodate photovoltaic panels and utilize alternative energy sources. The building is designed to have nearly zero energy consumption.

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.
