The aim of this Master’s thesis is the design of a library building with a café. The thesis is divided into three parts.
The first part focuses on documentation for building permit. The building is designed as a three-storey, detached structure with a partial basement. The first floor houses a café and a multipurpose hall; the second floor contains the library premises. The partial basement serves as a technical facility and library archive. The building is based on a combination of foundation strips and pads. The building's vertical structures are masonry, mainly sand-lime bricks and permanent formwork blocks in the basement. The facade consists of a combination of a vegetation trellis and a ventilated facade. The horizontal structures are made of prestressed reinforced concrete panels. The roof is flat, green.
The second part focuses on building services design. A ground-water heat pump serves as the source of heat and cooling in the building. Water heating is partially covered by the heat pump, using hot water cylinders and partially by electric flow heaters. Air exchange will be covered by forced ventilation through three air handling units. The building’s electricity demand will be partially covered by a photovoltaic system, with panels installed on the roof of the building. Rainwater harvested from the roof through will be collected in a storage tank and used for irrigation. Overflow will be infiltrated in an underground infiltration system.
The specialized part involves a thermal assessment and cost comparison of selected variants of brackets for anchoring of the outer shell of the ventilated facade. The goal of this part is choosing the most suitable variant for use in the structural design of the building of the Master‘s project. Comparison is made among several material variants (aluminium, galvanized and stainless steel), as well as positioning of thermal breaks (insulating pad or web). Thermal assessment is based on calculated point thermal bridge values affecting exterior wall’s U-value. This calculation is based on 2D heat flow, calculated from 3D model, created using CalA software. After analysis, additional required thermal insulation was calculated, and cost of materials was assessed. Due to lowest combined material cost, galvanized steel brackets were determined as the most suitable option.
