Rodinný dům v Soběšicích

Abstract

Detached house, nearly zero-energy building, low-energy construction, building physics, mechanical ventilation with heat recovery, heat pump, construction details, rainwater harvestingThis bachelor thesis focuses on the design of a detached single-family house with nearly zero energy consumption, intended for a four-member family. The building is in the Soběšice district of Brno on a flat plot and consists of two above-ground storeys. The massing of the house is compact, with the second floor partially recessed and partially covered by an extensive green roof; the upper roof is designed as a flat roof with a gravel finish. The architectural concept emphasises simplicity, functionality, and contemporary aesthetics. The internal layout is divided into day and night zones. The ground floor includes an entrance hall, a staircase corridor, a utility room, a separate WC, a storage room, a pantry, a study, and the main living space – a living room connected to the kitchen and dining area, with direct access to a terrace. The upper floor comprises a master bedroom, two children’s bedrooms, a bathroom, and a separate WC. The thesis is divided into two parts. Part A contains the architectural and structural design, building physics assessment (thermal performance, acoustics, daylighting, and sunlight exposure), and fire safety design. Part B focuses on the design of building services – specifically the concept of plumbing, heating, electrical installations, and a detailed mechanical ventilation system. It also includes the energy performance certificate of the building. The load-bearing structure consists of sand-lime brick masonry and monolithic reinforced concrete floor slabs. The building envelope is insulated using an external thermal insulation composite system (ETICS) with 300 mm mineral wool. Heating is provided by an air-to-water heat pump connected to a low-temperature underfloor heating system. Ventilation is designed as a balanced mechanical system with heat recovery. A photovoltaic power system is installed on the roof, including battery storage. Rainwater is collected for garden irrigation, with any surplus managed through on-site infiltration.
