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.

Fire station
Wrana, Lukáš ; Šteffek, Libor (referee) ; Ostrý, Milan (advisor)
The subject of this thesis is to create a project documentation of the design of new construction of fire station in Šumperk. The fire station is designed according to ČSN 73 5710 as a C type station that will be used by professional fire brigade of Olomouc district. The object is structurally divided into two parts - a masonry building, and a reinforced concrete frame. The administrative part of the building together with the base of the fire brigade, technical room, and a fire tower are designed as a masonry building made of Ytong cellular concrete units. One of the parts is designed as a two-level object, while the technical room and the fire tower are designed as a sigle-level object. The circumferential masonry is insulated by contact thermal insulation system. The floor construction is made of Spiroll prestressed floor slabs. The roof is designed as a warm flat roof. The garage is a single-level building with built-in structure of storerooms in part of the garage. The precast reinforced concrete frame is set on foundation pads and foundation sills. The horizontal and vertical supporting structure consists of reinforced concrete parts – columns, Spiroll floor slabs, floor girders, sway frames, purlins and small purlins. The whole object is covered by a warm flat roof. The external cladding consists of PUR isolating sanwich panels.

Renovation of municipality office
John, Josef ; Klubal, Tomáš (referee) ; Ostrý, Milan (advisor)
This thesis deals with the reconstruction of the Adamov municipality,based on a solution of barrier-free building use, overall improvement of the energy performance of the building and creation of new office spaces in the form of a loft. The object is located on a building site in the town Adamov. The object is currently connected to a III. road, parking space and utilities. It is a building with three above-ground floors and one basement floor. The ground plan of the municipality is rectangle-shaped, the maximum outline dimensions of the rectangle are 28.38 x 16.70m. Existing vertical supporting constructions are mason made of fired bricks. The roof frame structure is made of wood, construction framework stagnant stool, fired tiles are used as roofing. Floor surfaces are formed by ceramic tiles or vinyl. The entrance part is covered with a flat roof. The entrance area will be redesigned as a barrier-free, with a connection to the elevator that goes through the entire object. The sanitary facilities in the first and in the second floor will be renovated. Newly created attic floor will be – except for the lift - connected to the interior of the building by a new steel staircase and the walls on this floor will be of a light type. Holes fillings will be changed in the perimeter walls. A thermal insulation of the entire object by a contact heating system will take place.
