Energy-saving detached house
Ondruš, Marek ; Struhala, Karel (referee) ; Kolář, Radim (advisor)
The aim of the bachelor's thesis is to design a single-family house that is low-energy. The building is located in Hlučín, Opava district. The two-story detached L-shaped house features a flat sedum roof on the top and a flat roof that serves as a step-in terrace on the first floor. The main entrance is situated on the north-east side. The ground floor comprises a utility room, a small bathroom, a study room, a storage room under the staircase, and a social zone that includes the living room and a kitchen connected with the dining room. The first floor is the private zone that contains two children's rooms, a master bedroom, a main bathroom, and a walk-in wardrobe. The building's foundations are concrete strips, while the main load-bearing structures are masonry walls designed from sand-lime blocks with ETICS insulation and a reinforced concrete floor slab. The building's heating and cooling is powered by an air-water heat pump, which also heats the hot water. Comfortable indoor microclimate provides a heat recovery ventilation unit with supply ducts in ceiling voids and fans in rooms. Rainwater is collected in a stormwater accumulation tank and reused for toilet flushing and watering the garden. The photovoltaic panels on the main green roof generate energy that can be stored in batteries or used for household appliances. The building is connected to the combined sewer, water service pipe, and electricity service. External blinds and a pergola shading system help to reduce overheating during summer.
