The aim of the Bachelor’s thesis is to design a nearly zero-energy detached house. The thesis consists of two parts: the architectural and structural design and the design of building services.
The house designed for a family of four is situated at the foot of a slope on a plot in the village of Osík. The house has two sections and is divided by an atrium. The single-storey section contains a living room with a kitchen and serves as the social area of the house. The ground floor of the two storey section is embedded into the slope and accommodates a utility room, a toilet, a bathroom, a study, and a guest room. The first floor with three bedrooms and a bathroom forms the private zone. The structural system consists of concrete strip foundations, masonry made of ceramic blocks, and prestressed concrete floor panels. The windows with triple glazing and the entrance door have timber-aluminium frames. The house is insulated with mineral wool and covered with a warm flat roofs.
The source of heat for space heating and domestic hot water preparation is an air-to-water heat pump in a split configuration, complemented by photovoltaic panels installed on the roof. Space heating is provided by a low-temperature underfloor heating system. The building is equipped with a balanced mechanical ventilation system with heat recovery, where the supplied air is filtered and distributed through ceiling diffusers and disc air valves. Rainwater from the roof is collected, filtered, and stored in a storage tank for subsequent use in garden irrigation. The building achieves energy performance class A, indicating an exceptionally energy-efficiency.
