Segeďa, Petr ; Rubinová, Olga (referee) ; Počinková, Marcela (advisor)
The aim of the master’s thesis is to design an energy-efficient hotel in Karviná. In the first part, an architectural and structural solution was proposed. The building has three above-ground storeys. The structural system was designed as structural frame with beams and slabs, made of reinforced concrete. The material of external wall is aerated concrete blocks insulated with the ETICS with poly. The roof is flat. There are 40 thermal collectors and 69 photovoltaics panels. On the first floor, there are four guest rooms, a restaurant, a kitchen, a reception, toilets, a utility room, a mechanical room, and facilities for employees. The guest rooms are located on the second and third floor. HVAC was designed in the second part. Heating is provided by two heat pumps. The first heat pump provides domestic hot water in the winter, heating with radiators, for air handling unit heaters and cooling in the summer. The second heat pump is used only for floor heating in the winter. In the building are designed four air handling units for the kitchen, the restaurant and two for the guest rooms. Rainwater from the roof is collected in accumulation tank for flushing the toilets. In the third part, I evaluated the calculation of energy performance certificate in two softwares, namely Energie 2021 and DEKSOFT. The aim to find out, why the results are different in these softwares. The Drawings were done in ArchiCAD. The calculation part was made in Excel.
