Cowhouse in Králíky
Nováček, Tomáš ; Štrba, Michal (referee) ; Barnat, Jan (advisor)
Bachelor thesis describes the structural design of the load bearing steel structure of cowhouse located in the municipality Králíky. The structure is designed according to the normative requirements of ČSN EN for ultimate and serviceability limit state. It´s a structure formed by the main frames at a distance of 5 m apart, which are placed in a rectangular plan of 30 x 60 m. As the main material of load bearing elements was used a steel S355. The specificity of the structure is location in a place with above average snow and wind loads. The couwhouse is intended for housing hundred and fifty cows. The work consists of a static calculation, which assessed individual cross sections and joints.

The influence of internal thermal storage mass used in passive houses' construction systems on their summer thermal stability
Němeček, Martin ; Hraška,, Jozef (referee) ; Katunský,, Dušan (referee) ; Kalousek, Miloš (advisor)
In recent years we may observe a growth in construction of passive houses and low energy houses using lightweight constructions such as modern wooden houses. It is assumed that wooden houses keep overheating more comparing to brick houses during summer period. Due to the lack of research in this field the paper investigates the influence of internal thermal storage mass in passive houses constructions on their summer thermal stability under the Czech climatic conditions. Only sensible heat accumulation without a usage of phase change materials is examined. Differences between wooden houses comparing to brick-built houses are emphasized. Objects of research are mostly residential passive houses in low energy building standards. However, the results of research might be applied to different types of buildings as well. The first section outlines theoretical fundamentals. For the research itself various scientific research methods were used, such as basic mathematical calculations, experimental temperature measurement of two buildings (detached house in Dubňany and in Moravany) and numerical simulations. Own tribute to the research was first of all discussion on the topic of thermal accumulation and structures heat capacity calculation. Experimental measurements outlined conclusive evidence about the importance of internal thermal storage mass in respect of interior summer overheating. The research confirmed that the highest interior temperature reached is mostly influenced by solar gains through unshaded windows. However, the influence of internal thermal storage mass is not remote. If we compare standard timber-framed wooden house to the hole ceramic bricks-built house, the wooden house will overheat by 0,5°C more during a standard day. Wider spread in the maximum temperature reached was measured for lightweight consturctions wooden houses without any internal thermal storage mass. Therefore, such structures should have an additional layer of thermal storage mass.
