The subject of diploma project is the design of complex of buildings using hemp lime composite, in English known as Hempcerete. Four detached houses are completed by building of facilities. Buildings have one to three floors. The composite fiercly reduces carbon footprint in building industry. The design is focused on different construction systems using hemp lime composite as a wall filling. Detached houses are made of load bearing timber frame with cast-in-situ hempcrete, building of facilities is made of reinforced concrete with precasted blocks. All buildings are cellarless. Detached houses are shed roofed, building of facilities is gable roofed.

Multifunctional house U zvlněné krajiny
Uchytilová, Tereza ; Spáčil, Miroslav (referee) ; Sedláková, Markéta (advisor)
The aim of the diploma thesis is the processing of project documentation for the construction of a multifunctional building. The building is situated on the outskirts of the village Brod nad Dyjí, on buildings plots 4002/4, 4138/1. The multifunctional building is divided into two parts, where the main part is four-storey, partly with a basement and the other part i sone-storey. In the basement are situated cellars, bicycle room, pram room, warehouses and technical room. In the ground floor is situated rentable retail space. In the second floor is situated six rentable office spaces of various sizes. There are housing units on the third and fourth floors. On each floor there are 8 residential units od size 1+kk, 2+kk, 3+kk and 4+kk. Both floors are identical in division. Each aparment and office space has at least one loggia. Theo ne-storey part of the building is a cafe in which there is an atrium. The perimeter walls of the basement are made of reinforced concrete, the other perimeter walls are made of ground brick blocks. The building is insulated with ETICS contact thermal insulation system. The ceiling structures are cross-reinforced monolithic reinforced concrete slabs. There is an elevatorin the multifinctional house. The roof of the four-storey part is a double-skin flat roof with sheet metal roofing. The roof on the single-storey part is a flat green roof with a waterproofing layer of asphalt strips. The staircase is a monolithic reinforced concrete slab. There is wall structural system.

Optimization of a lightweight pitched roof in order to reduce summer heat gains
Svobodová, Sylvia ; Rubina, Aleš (referee) ; Sedlák,, Vladimír (referee) ; Matějka, Libor (advisor)
The thesis deals with the topic of overheating of attic rooms during the summer period. In vast majority of family houses and apartment houses with inhabited attic spaces is the roof solved as lightweight. This kind of roof assembly is not able to sufficiently resist the summer boundary conditions and leads to increased heat gains in the interior. In this work, the attention is drawn entirely to the heat penetration through the roof. Different aspects of passive cooling were applied to the roof and the impact of each change was assessed. This concerns the color of the tiles, thermal accumulation, reflective surfaces and the ventilated air layer. The temperature and velocity profiles in the ventilated cavity were monitored and an analysis of the ventilated cavity efficiency was conducted. For individual analyses was used software – based on the principles of the Finite Element Method or the dynamic simulation software. Also other methods were employed: long-term measurement of temperatures on roof models; short-term measurement of surface temperature of various kinds of roof tiles; and laboratory measurement of reflexivity. Also the effect of insect grilles on the air flow is discussed; which was tested on a ventilator track. In this publication are explained the principles of natural convection; boundary layers and the theory of the coefficient of heat transfer. This work includes a standard of the precise calculation methodology for ventilated roofs which was developed for the purpose of creating a user-friendly guide. The results of individual analyses show, a definitely positive effect of the ventilated cavity on the heat gain reduction of attic rooms. The current technical solution of a roof ridge provides the exhaust of the water vapor from a roof assembly; but for providing ventilation for reducing heat gains is insufficient. This lead to a concept of an innovative roof ridge design which enhances the air exchange between the cavity and outdoor environment.
