This master’s thesis addresses the design of a two-story fitness center in Ostrava. It is a detached building in the shape of a regular pentagon, covered with a flat sedum roof. The entrance to the first floor of the building faces southeast and includes a reception area and bicycle storage room. The first floor also features changing rooms, restrooms, and spaces for functional training, yoga, and martial arts. The first floor is connected to the second floor by two staircases and an elevator. The second floor is designed for weight training, spinning, jumping, and TRX training, and also features an outdoor terrace for seasonal outdoor exercise. The foundations of the building consist of reinforced concrete footings, the load-bearing structure of the building is a reinforced concrete skeleton combined with infill masonry, and the individual floors are separated by reinforced concrete ceiling slabs. The building envelope consists of a ventilated facade and a partly of curtain walling.
The building is heated by a ground-water heat pump using ground boreholes. In summer, this system also provides cooling in reverse mode. The heat pump also heats hot water and is supplemented by a bivalent source in the form of a gas boiler. Air exchange is provided by air handling units located on the roof of the building, together with photovoltaic panels. Rainwater is collected in an underground tank on the property and reused for irrigation and toilet flushing. The building is connected to a unified sewer system, medium-pressure gas pipeline, water supply, and elektricity. External shading system and, in some places, a climbing green facade are installed on the glass surfaces of the building.
The third part of this master’s thesis focuses on the assessment of the building envelope of a designed fitness centre, to compare selected glazing and external shading systems and evaluate their impact on thermal performance, heating, and cooling demand. The assessment is based on computer simulations performed in DesignBuilder software, which enables detailed analysis of heat transfer, solar gains, and indoor climate. The results were subsequently used to optimise the selection of envelope components with respect to energy efficiency, indoor thermal comfort, and investment cost of the solution.
