Chalet under Poľana
Babicová, Ivana ; Šteffek, Libor (referee) ; Ostrý, Milan (advisor)
The aim of my diploma thesis is to design the object of a chalet, which is intended for recreation, boarding and accommodation. The accommodation is designed for 16 people in the form of tourist accommodation. The land, on which the proposed building is located, is on a slight slope, in an uninterrupted area in the protected landscape area of Poľana. Access to the land is secured by asphalt road from the northeast side of the land. It is also accessible by a tourist route from the southeastern side. The affected area is located approximately 10 km from the nearest village Hriňová. In the past, the site was often used for recreation. At a distance of 1 kilometer is the old mountain hotel Poľana, which is out of operation, but provides only temporary accommodation. The new chalet should return tourism to this area and increase the interest of tourists. The underground floor has a separate service for servicing and borrowing sports equipment. The building has one underground floor partially embedded in the terrain, from the south side accessible for the public. Two above-ground floors are made up of CLT panels, the first serving for a restaurant and a private dwelling unit, the second one for accommodation. The underground floor is designed with concrete filling blocks. The roof is a saddle, made of wooden collar construction. On the south side of the building is a large dormer.

Possibilities of energy savings in the residential house Merhautova
Bartek, Čeněk ; Kalánek, Jiří (referee) ; Ostrý, Milan (advisor)
The diploma thesis is about the reduction of the energy intensity of the existing residential house Merhautova. The design documentation is focused on the thermal insulation of the living area, the replacement of windows and doors according to the variant of the design, accessible entrance to the house, loggia on the south side of the building and the replacement of the roofing. At the beginning of the diploma thesis the experimental part of the thermography was performed. Images of the existing object by the thermal camera were taken and building survey for the design documentation of the current state of the building was performed. Within the theoretical calculations the energy performance certificate was processed in options of the entering the thermal bridges. The energy performance certificate with thermal bridges calculated according to the details was compared with the energy performance certificate with estimated thermal bridges. A comparison of two options of the replacement of windows and doors was made in realation of the energy intesity of the building. A preliminary budget of these two options was also calculated with regard to the expected simple return on investment due to the heat saving.

Integration of phase change materials in building structures
Klubal, Tomáš ; Šťastník, Stanislav (referee) ; Solař,, Jaroslav (referee) ; Ostrý, Milan (advisor)
The thesis deals with the integration of phase change materials (PCMs) into building structures. The basic requirement is improved thermal stability during the summer season without using an air conditioner. This can be achieved by increasing the thermal storage capacity of the building structures. If the thermal capacity cannot be increased on the level of weight, phase change materials can be used. These materials are capable of storing latent heat and thus increasing the thermal storage capacity of the building. In the thesis the phase change materials were investigated in a thermal incubator by thermal analysis and, above all, in full-scale experiments using comparative measurements. The comparative measurements were carried out in two attic rooms at the Faculty of Civil Engineering, Brno University of Technology, where in one was used as a reference and the other for the experiment. Manufactured heat storage panels were installed in the experimental room. These panels are composed of a base plate; the capillary tubes placed on it are coated with modified plaster. The gypsum plaster is modified with micro-capsules paraffin for improving the thermal storage capacity. This system is connected to a thermal air-water pump, by which the storage panels can be additionally cooled or heated. In the experimental measurements, different operating modes were investigated and their effect on the indoor environment was evaluated. Thermal storage in PCMs dampens the temperature amplitude in the building during the summer season and, at the same time, allows the stored heat to be discharged during the night. Moreover, the time interval of withdrawing electric energy from the supply mains is much shorter than in the case of air conditioning. A conventional air conditioner must operate simultaneously with the thermal load, i.e. at the time of peak consumption of electric energy. Thanks to the set regimes, the installed system is capable of responding to external thermal condit

Optimizing the design of modern low-energy wooden houses
Vahalová, Eva ; Ostrý, Milan (referee) ; Doc.Ing. Miloslav Bagoňa, Ph.D (referee) ; Šuhajda, Karel (advisor)
The main aim of the thesis was focused on hygrothermal simulation of critical details of two prefabricated wooden buildings - especially connections of the perimeter wall to monolithic foundations, respectively with waterproofing layer. The composition of the external walls of these selected buildings has quite different compositions and thus different potentials of drying integrated moisture from the components. Practical measurement of moisture weight-content was applied to the wooden bottom plate, which is in direct contact with the concrete slab structures. The influence of different design solutions on hygrothermal characteristics of the wooden plate was examined with regards to the risk of mould growth, analysis of mass loss due to the decay fungi and with the aim to estimate the durability of the studied details of prefabricated wooden houses. The subsequent research focused on the differences in physical and mechanical properties of natural spruce wood (Untreated, (-), A) and impregnated spruce (Treated, (+), B) using supercritical CO2 and its possible impact on wood protection for mould growth. Samples of identical Untreated and Treated spruce were collected in the laboratory and subjected to thermal and hygrothermal experiments. The comparison of the resulting values of the individual experiments is presented. Required values needed for numerical calculations were obtained from these experiments. In conclusion, the summary of founded comparison is presented. The mould growth analysis and its influence on the durability of wooden structures offer a view of the behaviour of the structures. Relevant findings and recommendations for the future praxis are mentioned.
