Ent, Michal ; Vlach, František (referee) ; Vajkay, František (advisor)
The aim of the bachelor’s thesis is to design an energy-efficient house for a single-family residence situated in Zlín, featuring two stories and a flat roof. The architectural layout emphasizes the organization of rectangular spaces, with the ground floor serving as the social zone comprising a living room connected to the kitchen, a bathroom, an office, a garage, a closet, and a utility room. The first floor is designated as the private zone, encompassing a master bedroom, walk-in closet, two separate rooms for children, a separate toilet, and a bathroom. The structural foundation is established on reinforced concrete strips, utilizing masonry made of ceramic blocks for vertical elements and in-situ reinforced concrete for horizontal load-bearing structures. The second part of the thesis focuses on the design of heating, hot water supply, electricity generation, and mechanical ventilation systems. The heating system is conceived using an air-to-water heat pump, which serves for heating as well as heating the hot water in the storage tank. To minimize reliance on electricity from the public grid, a photovoltaic hybrid power plant is proposed for the house. In the concluding section, the bachelor's thesis deals with a detailed design of mechanical ventilation with heat recovery. This technology enables efficient ventilation of the building while simultaneously minimizing heat losses by recovering heat from the expelled air. This comprehensive approach to building design increases the energy efficiency of the house and reduces its environmental footprint.
