Office building with cafe
Ondrová, Martina ; Krupica, Roman (referee) ; Jelínek, Petr (advisor)
The aim of the Master‘s thesis is to design a detached near-zero energy office building with a café. The building is designed as three-storey detached building with the café on the first floor, offices on the first and second floor and the third floor contains building services. The thesis is divided into three parts. The first part consists of architectural and structural designs. The building has foundations combining foundation pads, strips, and a foundation slab under a reinforced concrete core. The superstructure is designed as a reinforced concrete frame with ceramic infill walls and ventilated facade. The floor and warm flat roof structure is designed by using prestressed hollow core panels. The second part focuses on the design of building services and energy efficiency assessment. Heat for space and domestic hot water heating will be provided by air-water heat pumps which would also provide cooling in summer. The building will have mechanical ventilation. The electricity demand will be partially covered by a photovoltaic system. The photovoltaic panels will be placed on the roof. The artificial lightning will be used in the building. The rainwater drained from the roof through roof drains will be directed into a storage tank and reused for flushing toilets. If there is an excess, the water will be diverted via an overflow to a seepage polder on the plot. The third part of the Master's thesis involves a thermal assessment of selected structural focused on thermal bridges. Structural focused is dealing with the anchoring of structures into the building envelope provided by thermal insulation assembly blocks at the anchor points to brake thermal bridges. Calculation of the linear thermal transmittance has verified that thermal bridges do not occur in selected critical points. The calculation of the linear heat transfer coefficient involves two calculation methods, which are compared on the basis of the results in terms of practical application. The used software: AutoCAD, SketchUp, Lumion, Deksoft, BuildingDesign.
