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.

Rodinný dům systému NOVATOP
Loučková, Veronika
This thesis is focused on the family house design, whis is using massive wooden construction by the company NOVATOP and is based on my bachelor thesis from year 2016. The first part of the thesis solves the layout according to valid regulations and standard requirements. The thesis contains drawing part and production documentation including a statement of materials. In the text part of diploma thesis are described all possible variations of side walls and the most optimal possibility is chosen according to thermal-technical properties. In this part are also described chosen structure of the construction for family house and structural detail. Also the price was enumerated for peripheral construction, which is compared with the price from the bachelor thesis from 2016. The diploma thesis also contains accompanying and technical report of the object.

This thesis focuses on the house design, which is using massive wooden construction by NOVATOP. The first part of the thesis solves the layout according to valid regulations and standard requirements. Project documentation was also made for this family house. In the second part are described characteristics of selected construction system, selected construction compositions and also construction details. The final part is focused on assessment of peripheral structures in terms of requirements for thermal protection of buildings, price comparison of wall with facade plaster and wooden cladding. This part also approximately values the house according to the unified classification of buildings. The bachelor thesis also contains accessory and technical house report.
