Study of reaction to fire tests for thermal insulating materials
Krivda, Antonín ; Novák, Vítězslav (referee) ; Sedlmajer, Martin (advisor)
This bachelor thesis deals with thermal insulation, it is fire resistance and reactions to fire. The thesis also approaches the testing of thermal insulation materials. In detail, it focuses on the Small flame test, Calorific value determination and the Flameproof test. The test methods were performed on insulators based on polystyrene and mineral wool. The literary research focuses on the fire safety of buildings that have been already insulated.

Hotel "U Prehrady"
Černý, Dávid ; Nováková, Eva (referee) ; Kolář, Radim (advisor)
The subject of this diploma thesis was to process the study and the design documentation for a newly built hotel in Brno, in city district “Kníničky” near the artificial dam “Přehrada” in a rest area. The hotel will serve as temporary accommodation for up to 64 hotel guests in single, double and four bed rooms. The object also contains training rooms, offices, a meeting room, a café, a small grocery store and a restaurant with kitchen. Parking is possible in one of the two mass garages and there is an outdoor parking possibility in front of the hotel too. The building has a cast-in-place concrete frame with longitudinal beams and sway bracings. The external wall consists of aerated concrete bricks with contact thermal insulation system ETICS (insulation material mineral wool), the ceilings will be cast-in-place reinforced concrete ceilings and the roof flat green roof or flat roof with gravel on it above the 5th floor. The foundation construction consists of reinforced concrete foundation strips, which expand to foundation pads under the load-bearing columns and will be supported by piled foundations under the most exposed elements. As long as the hotel is situated into a fairly steep slope, the vertical alignment of some building parts is various so part of the project is the design of landscaping works. Design documentation was processed using the program AutoCAD 2017, the study and the visualization using both SketchUp 2015, LayOut 2015 and Lumion 5.

Construction technology stage of the perimeter shell of the elementary school in Slažany
Kozla, Dávid ; Nečasová, Barbora (referee) ; Diaz, Yvetta (advisor)
This bachelor thesis solves the building-technological phase of the perimeter shell of the elementary school in Slažany. Specifically, it deals with the cladding of the wooden superstructure of the 3rd floor of the primary school building and the additional insulation of the existing floors. The shell of the superstructure is covered with a wooden cladding and filled with mineral wool insulation. Additional insulation is designed as a contact from facade polystyrene boards. The work is elaborated technical report, thermal assessment of cladding, technological procedures at given stage, transport solution including design of the machine assembly and situation, budget stage with report statement, principles of organization of construction including technical report and drawing of construction site, control and test plan, time schedule and safety.

The impact of executing new thermal insulation on a apartment building on the expenses associated with its operation
Machová, Petra ; Kosová, Jaroslava (referee) ; Čech, Josef (advisor)
The topic of the diploma thesis „The impact of executing new thermal insulation on a apartment building on the expenses associated with its operation “ is a draft and appraisal of four variants of thermal insulation of the building. The thesis deals with the assessment of the current proposal for apartment building envelopes along with proposing alternative plans with emphasis on reducing heating costs. The first section describes the types of buildings according to heating demand and a list of different variants of thermal insulation materials. The second part is devoted to a specific apartment building in the Ústí nad Labem for which there are designed in four variants of insulation. The work includes thermal assessment in original condition and the assessment of new condition modified by adding thermal insulation. Through research will bedetermined price of implementation of proposed insulation options together with the costs of operation of the apartment building. In conclusion, the diploma thesis evaluates the payback period of insulation.

The impact of executing new thermal insulation on an administrative building in Blansko on the expenses associated with its operation
Kopřivová, Petra ; Bradáč, Albert (referee) ; Čech, Josef (advisor)
The topic of the diploma thesis „ The impact of executing new thermal insulation on an administrative building in Blansko on the expenses associated with its operation“ is a draft and appraisal of four variants of thermal insulation of the building (EPS, EPS G, Mineral wool, Phenolic foam). It deals with an actual building situated in Blansko. All the variants are projected according to the same technical specifications (thermal transmittance) and their thermal parameters, technical parameters and the rate of return have been assessed. The assessed building (The A building) is at rectangular shape. It has six above - ground floors and a basement, it contains mainly administration sites. The construction system is concrete frame, which has curtain wall made of perforated blocks with thickness 250 mm. The building has got reinforced concrete floors, the roofing is made of double-skin roof construction. The supply for heating is a separate gas boiler room.

Mountain pension
Bačina, Jan ; Pospíšil, Tomáš (referee) ; Pěnčík, Jan (advisor)
This diploma thesis solves the project of four-storey, partly cellared mountain pension situated in the plant number 645/2 in the cadastral area in Deštné in Orlické hory. The building has a capacity of 44 seats to accommodate 72 persons in the restaurant and 57 persons in the wellness center. There is a wellness center with fitness room and engine room of air-conditioning system in the basement. There is an entrance hall with hotel base, restaurant, sanitary facilities and utility room with boiler room on the first floor. The second and third floor is designed for accommodation. There is an outdoor terrace of restaurant. The building has a load-bearing wall system. The load-bearing walls and the partition walls are bricked up of the porous concrete YTONG bricks and sand-lime bricks SILKA. The walls are insulated of mineral wool thickeness 200 mm and EPS Perimeter thickeness 140 mm underground section and plinth area. The ceiling structure are made of the prestressed hollow core panels spiroll thickness 250 mm and wooden beamed ceiling. There is a saddle wooden roof. The windows and the doors are made by the company Progress. The part of facade of the building is ventilated. This project is designed by the computer software ArchiCAD.

The influence of the outdoor temperature on the properties of the reinforced layer in the implementation of ETICS
Novotný, Michal ; Gašparik,, Jozef (referee) ; Schmid, Pavel (referee) ; Sedlák,, Petr (referee) ; Lízal, Petr (advisor)
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.
