Matějka, Libor ; Bura,, Roman (referee) ; Pěnčík, Jan (referee) ; Doc.Ing. Karel Kubečka, Ph.D (referee) ; Matějka, Libor (advisor)
This thesis deals with the optimization of structural details for flat single-leaf roofs. In the first part of the thesis, 3 groups of structural details for flat roof (flat roof parapet, gutter at flat roof without overhang of the roof cladding, intersection of the flat roof and vertical supporting structure) are characterized, classified and examined. In every group one of these structural details is designed with use of modern composite material based on secondary raw materials (still in development process). The theory describes the current issue of thermal bridges at constructions and applicable legislative documents. The next part introduces thermal engineering analysis (based on finite element method) of structures with annotated data outputs. The another main part of thesis provides with designed innovative optimization algorithm using multi-criteria decision analysis methods, which is then practically tested on the surveyed construction details. The conclusion summarizes the results and provides with improvements based on completed research.

One of the important reasons for the choice of the thesis topic are increasing requirements from the persons interested in low-energy, passive or even houses with almost zero energy consumption. During decreasing of the energy demand is within the framework of the idea of sustainable construction not only required to decrease the total energy demand of the buildings, search and solve the critical spots in the building jacketing, but also to use the secondary raw materials as full-value substitutions for commonly used products from the primary raw materials. The thesis tries to contribute to the possible usage of polymeric wastes in building industry. In an early stage of the thesis the main and partial targets together with the consecutive steps leading to their fulfilment were set. Selection of the suitable secondary raw materials, discussion with the specialists, initial sample mixing, finding their thermally – technical characteristics, press mould and fire kiln acquisition was carried out during the stage. The next phase is focused on the application of the products made from the secondary raw materials to the building envelope. The products are moulded according to the thermally – technical properties. Performed moulding approved that the products are fully functional and after reaching the required value of heat conductivity coefficient products eliminate imperfections of the solutions used at present. Strapping product for the threshold door joint is registered at Industrial Property Office of the Czech Republic and at European Patent Office at the same time. Recycled materials put into production represent possibilities how to decrease number of acquired virgin materials, need of primary energy and how to decrease risks connected to the waste disposal. Society is starting positively approaching to the products that are partially or fully produced from the secondary raw materials. Nevertheless, before the products from the recycled materials enter the peop

The trend in today's civil engineering are growing demands for quality and comfort constructed buildings and spaces in them. This trend causes a change in the approach to designing buildings and building new buildings. One of the main directions great importance is attached dedicated reconstruction of buildings and their technical adjustments to meet the ever increasing demands being norms and laws. One of the most monitored parameters are thermal-technical characteristics of objects - i.e. better quality means saving on heating costs. In this connection there is a big trend of the modern construction industry and building insulation, mainly ETICS systems. Dissertation focuses on the basic (reinforced) layer of the ETICS and examines the effect of low temperatures, acting on the matter in the implementation of the system, the properties of this layer. This coating is one of the key elements of the system, which more or less determines the quality and durability of the system. The first part deals with the current state of the problem and generally insulation systems, basic types and the advantages and disadvantages of these systems. In the main part of the work is solution focused work, its objectives and methodology for testing materials using laboratory tests and are mentioned outputs of experiments in terms of results. The final section addresses the evaluation of the data and results and output for construction practice. The theme of work was also addressed in the specific research. The works are also numerical and graphical attachments to records of experiments and calculations.

Comparison of heat losses calculation by CSN 06 0210 and CSN EN 12831
Elcner, Jakub ; Šikula, Ondřej (referee) ; Košner, Jan (advisor)
The diploma thesis deals with comparison of heat loss calculation by CSN 06 0210 and CSN EN 12831. This work contains short introduction to the heat loss calculation, definition of basic terms, detailed analysis of heat loss calculation by both standards, description of exemplar buildings, heat loss calculation and heat requirement for heating of buildings according to particular standards. At the end of the work the comparison and discussion of calculation results is presented.

Primary School
Forman, Daniel ; Manová, Ludmila (referee) ; Maceková, Věra (advisor)
Thesis Theme is a primary school, namely the outbuilding primary school Havlíčkův Brod, Konečná 1884. I suggest first grade pavilion and pavilion with school canteen with kitchens. Pavilions are based on the footings. Pavilions are designed as a two-way system from the wall HELUZ. Construction of ceiling are from ferroconcrete slabs are cross reinforced, single-layer roof is flat with a classic sequence of layers. In addition to construction and process layout I solved also the statics of building in specialize of concrete structures. The following are also evaluated heat and acoustic requirements and requirements for fire safety of buildings. New pavilions are solved as wheelchair accessible. Pavilion of the first grade has two floors with 5 classes of stem, 1 vocational and 2 classes are earmarked for after-school clubs. This pavilion is connected to the connecting neck between the former pavilon A and pavilion B. Dining pavilion has one floor, which is divided in the school canteen and kitchen is connected to the connecting neck leading to the gym. The land is mildly sloping to the south side. All consstructions comply with the applicable standards and recommendations ČSN.

Costing with using time standards of construction works
Wittek, Ondřej ; Tichý,, Jan (referee) ; Tichá, Alena (advisor)
This bachelor thesis is focused on costing with using time standards of construction works. In the theoretical part are described notions relating to costing, thermal bridges and standard time. Case study of this thesis is focused on costs comparison of two variants balcony design which are protected against thermal bridges. Comparison is performed by costing which is performed using costing computer program. The result of costing was affected by product prices which was found by research and by time standards which was created using a time measurement.

Family house
Diviš, Lukáš ; Pailová, Alena (referee) ; Maceková, Věra (advisor)
The topic of this bachelor thesis is a family house with one story above ground and residential basement under the part of building. Shed roof has a slope of 7%. As the load-bearing construction were used bidirectional structure walls made of Porotherm bricks. The building is situated on slightly sloping plot towards the west. All the used constructions are according valid ČSN regulations.
