Abstract:
The threat of depletion of fossil fuels is the driving force to diversify energy sources in the Czech Republic respectively in the European Union but also worldwide. One of these potential sources are being biomass boilers. The construction of these boilers has expanded in recent years because of government support for the construction of clean energy sources. Whether it is a burning of clean biomass or just incorporation of biomass to fossil fuels, teh substitution of fossil fuels and biomass boilers are the ideal solution. Their major advantages include significant reductions in emissions, mainly sulfur compounds, organic closure of the cycle of CO2 and disposal costs of spent residue.

The purpose of this Diploma Thesis is the construction design of the steam-boiler for the combustion of biomass – wood pellets. For the specified parameters have been defined stoichiometric calculations and calculations enthalpy burnt gas. In sequence, there is designed and solved the configuraion of the steam-boiler, so that the result design and the number of the heat-delivery surfaces can be determined, in dependence on the required inlet parametres of the air and outlet parametresof the water vapour. These parametres mean the amount, the temparature and the pressure. The aim of the thesis is to make a design of the steam.boiler burning biomass according to the set parametres.

The theme of the dissertation is design of new building of community center with a vicarage. The building is designed as a flat for a vicar, office of a vicar, new rooms for meeting of the churchgoers and new garden. The vicarage is designed near of church. The vicagareis designed in an area, which is prepare for building of cottages. The old vicacare is in old house in the other part of street Kostelní, than is the church. Existing flat for the vicar is unsuitable. Theobject is designed with one or two floors. The object is designed of tree parts: living part – a flat of the vicar and a flat for visitors, a community center – a parish hall and a hygienic rooms, an office part – an office of a the vicar and a clubroom. All parts of building are divide with fiction, design and used materials. The building is designed with a traditional materials as wood, concrete, masonry. The shape of building is designed from three diferent blocks. An parish hall i designed with rectangle layout, in the hall are designed two windows. The north-west corner of hal lis designed higher than other part sof room, because this corner is situated to church. This window is designed with frame in cross shape. The second window is connection between the garden and hall. The external fasade is designed from smooth concrete with links, that are designed in cross kapes. The links are designe as some crosses, that are designed in gold section. The office of vicar is designed with wood arc beams. The external fasade is designed from titanzinc sheets. The fasade is designed as wall and roof. The end fasades are designed from glass walls, because wood beams are a dominant of this part of building.

Abstract:
The content of the diploma thesis was an architectural study of a sacral building in Brno - Líšeň. The subject of the study was the elaboration of an ideological design of a sacral complex, which consisted of a church and a parish. The main operator of the whole complex will be the Salesian community, whose background is in close proximity to the area. The basic idea of the design was to design a spiritual place, which in its form conveys clear information about the use of the object and at the same time supports the development of ideas of the Salesian community. It is a structure that conveys the mission itself, not by one element, but by a set of several elements that together create a story, vision, mission. The ideological solution in this case thus becomes an equilateral triangle, which symbolizes the Father, the Son and the Holy Spirit. With its dominant vertical direction facing the sky, the object symbolically points to the spiritual path and self-realization. The given area is solved as a complex, the elements of which complement each other and thus create a harmonious whole. The design creates a space for both liturgical celebrations in the interior and exterior, which is used by the outdoor presbytery, which is complemented by residential stairs. These elements are intended to encourage residents to meet and establish friendly relations.

Abstract:
The thesis deals with European sacral architecture of the twentieth and the twenty-first century. Particularly, it refers to Judaic, Roman-Catholic and Islamic buildings. The second part puts into historical context the sacral constructions of individual religions including their function, characters and typology. In the third part of this thesis the representative sample of significant modern sacral constructions is selected, always under circumstances regarding their creation, the urban description and the setting in a specific location as well as the architectural layout, the interior arrangment and a possible use of special technological procedures at their construction. The mutual comparison and the evaluation of the modern European sacral architecture development are carried out in the fourth part. This section notices the function and the usage of light and presents some extraordinary buildings from this point of view. The final fifth part tries to answer the question, how a modern temple should look like.
