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.

Energy self-sufficiency residential units
Orlová, Lenka ; Škorpík, Adam (referee) ; Výskala, Miloslav (advisor)
This Bachelor’s thesis deals with the special community way of living in the residential unit called cohousing. The aim of the practical part is to define the possibillities of the heat and electrical supply to the cohousing by the renewable energy, make a price calculation and specify the return of the investment.

Energy usage of beer production
Maťa, Jakub ; Tuhovčák, Ján (referee) ; Hejčík, Jiří (advisor)
The bachelor thesis deals with the issue of energy consumption of beer production. The first part focuses on the technology of beer production itself, the understanding of which is a key prerequisite for assessing the possibility of using a heat pump for this process. The main part then describes the individual processes and their energy consumption. Finally, it evaluates the use of a heat pump and shows if it could reduce the energy requirements of beer production.

Energy assesment of single family house
Panovec, Jan ; Počinková,, Marcela (referee) ; Hirš, Jiří (advisor)
The aim of this bachelor’s thesis is to understand the nature of the energy assesment of building with low energy demand and energy-saving requirements. The calculations of energy intensity and experimental measurements of chosen parameters of inner microclimate in the building were done. Theoretical part includes requirements and principles of projecting buildings with low energy demand.

Influence of insulation of a house in Slavice on expenses related to the operation of the property
Pokorná, Jana ; Čech, Josef (referee) ; Nykodýmová, Veronika (advisor)
This master´s thesis deals with insulation of the house and it's costs. First part describes the energy performance of building, different methods of thermal insulation and types of thermal isolation. This thesis evaluates the influence of thermal insulation of residential building design for expenses associated with operating the property. This thesis uncludes thermal technical assessment of the condition of the house and then heat the assessment of the options for the thermal insulation on its economic return. In conclusion, the assessment of individual variants insulation is calculated as a simple payback period and the effect on price of this house.

Dry ice blasting for surface cleaning
Horňák, David ; Konečná, Eva (referee) ; Máša, Vítězslav (advisor)
This Bachelor thesis deals with dry ice blasting, which belongs to modern and effective surface cleaning methods. The websites of various manufactures clearly state that this method is utilized in many industries, but there is a low number of research articles dealing with this cleaning method. The amount of literature that covers the usage of this method in certain industries is also insufficient. For this purpose, systematic overview of dry ice blasting applications in industry is presented based on thorough review of literature. The technology of dry ice blasting including dry ice blasting machine and its individual equipment is also closely introduced. The thesis also includes the characteristic case study of high energy and economic intensity of this process. This study states that 94 % of cleaning expenses is linked with consumption of dry ice. The effective dry ice management is necessary from the economic point of view. Suggested saving measures follow on from these facts. These measures are: • process automation • custom applications • compressor optimization • replacement of compressed air with different form of energy Implementation of these saving measures can help greater extension of dry ice blasting in industrial practise.

The partial model of sewage treatment plant
Novák, Petr ; Ptáček, Michal (referee) ; Radil, Lukáš (advisor)
The thesis deals with wastewater treatment plants (WWTPs). For the energetic self-sufficiency of the WWTP, it is necessary to study the operational background, equipment and their possible operational prediction for energy distribution over time and adaptation to any renewable energy (RES). It is also possible to optimize the operation to maximize the equalization of the input power. We're talking about small WWTPs up to 500 EP. Large purification blocks are also an option. The student will evaluate the current state of knowledge and try to design and possibly implement the financial savings of the given concept.

Energy demands of localization algorithms
Maňák, Jiří ; Červenka, Vladimír (referee) ; Morávek, Patrik (advisor)
This masters thesis deals with technics of localization for wireless senzor networks with a focus on anchor free location algorithm by authors G. Jianquan and Z. Wei. It also describes the available simulations frameworks based on OMNeT++ platform and implementation of the anchor free algorithm in the simulation program Castalia. Furthermore, it deals with the energy demands of this algorithm based on results of simulations that were done for the communication unit IRIS.
