Low-energy construction
Halama, Miroslav ; Vaňková, Lucie (referee) ; Krejza, Zdeněk (advisor)
The bachelor thesis is proposing three construct variants of chosen family houses and assign each to particular energy performance certificate of A, B, and C values. Thesis describes trends in low-energy houses and theory of building valuation. Furthermore established financial indicator to determinate approximate building value and calculate investment efficiency and its correlation with operating costs. The aim of this study is economic analysis of investment efficiency of particular energy performance certificate buildings.

Residential Complex in Brno - Komín
Selnarová, Elisabeth ; Pospíšil, Zdeněk (referee) ; Boháč, Ivo (advisor)
Taking into consideration the slope of the terrain as well as the surrounding development, two types of residential buildings have been proposed: Komín a Komínek.They are placed in a regular structure into a given land. Sustainable development is at the core of the proposal. The residential buildings are proposed as sturctures created from multiple components. The framework is comprised of a reinforced concrete and the peripheral walls are stuffed with thermal insulating wooden panels. Air conditioned heating will be used (the air will be heated by a gas boiler). Due to the quality of the insolation, the houses are considered as low energy structures. As individual structures, each apartment has three sided orientation to cardinal direction. Some of the rooms have two sided lighting, which further increases their attractivness. The residential bulding is composed of Maisonette appartments, which together create asimilar structure. The fundamental space is intertwined with a ribbon that carries on its edges balconies, terraces or parking spaces. Each unit has a balcony, which allows the residence to relax and enjoy the surrounding landscape. The housing is proposed for a general audience (wider population). There are several types of appartments including no barrier appartments situated in the first floor as well as Maisonette appartments in the last floor.

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.

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.

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.
