Building for library purposes
Pastorková, Gabriela ; Blasinski, Petr (referee) ; Horák, Petr (advisor)
The aim of the Master’s thesis is to design near-zero energy library building in Kroměříž. The thesis is divided into three parts. The first part includes the architectural and structural design of the library. The building has two storeys. The first floor contains a lecture hall, a library, and technical facilities. The second floor contains another section of the library with a study space and facilities for employees, both floors are equipped with sanitary facilities. An accessible sanitary facility is located on the first floor. The building is founded on foundation strips supporting the load-bearing wall system made of ceramic blocks and a pre-stressed concrete roof and floor structure. The roof is designed as an extensive green roof, the roof over the entrance area is a warm flat roof. In the second part, I focus on designing selected building services. Key components include air-water heat pumps for heating and cooling, mechanical ventilation with heat recovery, LED-based lighting technology, and photovoltaic panels. The heating is provided by a hot water underfloor system, and rainwater management concept is designed as well. The building is assessed in terms of daylighting, acoustics, and thermal technology, including an Energy Performance Certificate. The third part of the thesis focuses on using thermography to identify potential thermal bridges. This section also encompasses the preparation of cost estimates for various insulation options, aiming to determine the optimal insulation solution for libraries that have been surveyed using a thermal camera. The analysis is focused on identifying a more cost-effective solution that provides optimal thermal insulation and minimizes construction costs. The thesis is created using ArchiCAD, BuildingDesign, Microsoft Office and Lumion software, along with the web portal DEKSOFT.
