The object of this master’s thesis is a newly-built mixed-use building in the town of Uherské Hradiště. It includes parking and office spaces, retail shops, and a coffee shop. The building is situated in a mildly sloping terrain near the town centre. It is a three-storey detached building with partial basement. The floor plan was created by joining several different-sized rectangles together. The mixed-use building is based on foundation pads and slabs. It is roofed with a warm flat roof and, above the first floor, with a green roof. The building consists of a cast-in-place reinforced concrete frame with columns and beams. The floor structure is composed of prestressed hollow core slabs. The external wall of the above-ground floors is made of hollow clay blocks and the basement external wall is made of permanent formwork. The wall of the lift shaft is built from reinforced concrete and the staircase is composed of precast reinforced concrete slabs. The external walls are insulated with contact thermal insulation system and in some parts there is timber cladding – ventilated façade with thermal insulation from glass wool. The thermal insulation of the basement and of the plinth is made of extruded polystyrene. The object is divided into several functional zones. On the ground floor there is a coffee shop, a copy shop, a stationery shop, and a bakery. On the first and second floors there are office spaces. In the basement there are technical facilities only.

Pressure losses in heating systems
Švanda, Martin ; Horká, Lucie (referee) ; Počinková, Marcela (advisor)
This diploma thesis deals with pressure losses in heating systems. The diploma thesis is divided into three sections. The first part is theoretical and deals with the occurrence of pressure losses. It discusses the properties of the fluid that affect pressure losses. It also deals with hydrodynamic phenomena, flow distribution, pressure loss distribution and its calculations. The aim of the second part, which is practical, was to create a heating project for a selected object. The object is a two-floor kindergarten building located in Velké Němčice. For this project, two heating variants were created. For the first variant, radiators and heating benches were designed and for the second variant, underfloor heating was installed in the building. The goal was to use a source which will gain heat mainly from renewable sources, so the air / water heat pump was chosen as the source of heat production. The project ends with a technical report. The third part of the thesis is dedicated to an experiment which purpose was to find out how the pressure losses of the connecting pieces are reacting to the change with the change of the heating water conditions (flow, temperature). Alongside, two pipes were created which differed in the type of connecting pieces so it allowed to compare how their pressure losses differ. Both pipes were connected by radial pressing, but the fittings differed in the quality of the brass, and therefore in the construction. Also, part of the experimental section of the diploma thesis is a description of the course of radial pressing of fittings from the Herz company.
