The Master’s thesis deals with the design of a nearly zero energy building at the level of documentation for building permit approval. The designed building is a non-basement masonry structure with two above-ground floors, intended for the operation of a fitness centre with sporting goods shop. The thesis is divided into three mandatory parts: architectural and structural design, building services engineering, and an optional part focused on detailed structural solutions.
The first part deals with the design of the spatial layout, structural system, and material solution of the building, including fire safety design and integration into the surrounding built environment. The building is designed as a combined system of load-bearing walls and columns, with an envelope made of sand-lime masonry units and a ventilated façade with a metal cassette cladding. This part also includes building physics assessments and the energy performance certificate of the building.
The second part focuses on the conceptual design of heating, cooling, ventilation, domestic hot water preparation, electrical engineeringy, artificial lighting, and sanitary installations. The building's energy concept is based on the use of ground-source heat pumps with borehole heat exchangers, mechanical ventilation with heat recovery, and a photovoltaic power plant installed on the roof of the building.
The elective part of the thesis addresses the design and assessment of selected building envelope details. The individual details are designed in two variants and assessed in terms of the minimum internal surface temperature and the linear thermal transmittance using a two-dimensional steady-state temperature field analysis by the finite element method. Based on the obtained results, the individual variants were compared, their advantages and disadvantages evaluated, and their technical feasibility assessed. Finally, the more suitable variants of the details were incorporated into the project.
