The aim of this Bachelor's thesis is to design an energy-efficient detached house. The thesis has two parts. The first part of the thesis is the structural and architectural design of the house. The two-storey house is located on a partially sloping plot in a newly developing area of Nový Jičín. The house is designed for a family of four. The ground floor is divided into a social zone and a utility zone. The social zone is dominated by a living room with an open-space kitchen, while the separate utility zone contains a utility room and a garage. The first floor contains a private zone including three bedrooms and a two bathrooms. The house is founded on plain concrete strip foundations. The vertical and horizontal load-bearing structures are made of sand-lime blocks and cast-in-place reinforced concrete, respectively. The house is covered with a flat green roof. The external walls and the floor are insulated with grey expanded polystyrene, while the roof uses standard expanded polystyrene. The house meets all requirements for building physics and fire safety.
The second part of the thesis is the design of selected building services. The primary heat source is a ground-to-water heat pump utilizing a  120 m deep borehole heat exchanger, which includes a built-in 180 l hot water tank. The living areas are heated by in-floor radiant heating, while the garage is heated by radiators. The house is ventilated by a central mechanical ventilation unit with heat recovery. Sewerage is connected to the  public sewers, while the rainwater is collected in a 6.3 m3 underground tank and reused for toilet flushing and garden irrigation. Excess water is infiltrated through soakaway boxes. A rooftop photovoltaic system with battery storage covers approximately 65% of the energy demand. The house is classified as energy class A, representing a  highly energy-efficient building.
