Next to the standard materials (concrete, glass, metal) there are in the building rubber flooring and bituterazzo flooring

Key Sustainability aspects
solar building integration, public spaces, accessability for disabled, innovative bulding materials, integrated planning process, participation of users in planning process, low cost design, use of innovative design tools
Social and ethical responsibility

The interior is very open and user-friendly, expressing the openness and friendliness. The main visual elements are the boldly colored floor and the orientation of all the lightings, which help visitors to orientate. Moveable, custom furniture was designed to give visitors a sense of freedom. Students can move and configure the pieces to create their own assemblies and seating constellations, reinforcing the primary interior design principals- collaboartion and reciprocal influence.

Ressource efficiency and environmental impact

The concrete structural system is a 15x15m grid with pre-stressed slabs and concrete core activation system to heat and cool the building. The building can be pre-cooled during summer months via natural ventilation. The main façade is divided into glazed and solid segments to optimize solar reflectance/absorbance. Recuperation of air and sun blinds, sheltered from the wind, are standard solutions. The ground floor surfacing material is bitu-terrazzo, significantly reducing noise. The roof is covered with extensive planting to create fifth façade and for water-retention.

Contextual performance and impact

Several sources influenced the concept. First, the site context, which addresses the historical urban plan and its present configuration. Second, the role of the library in today's society. Third, the shape and the materials express modernity and monumentality. Fourth, use of the area around the building; social space to the west and a green park to the east. Fifth, the interior and graphic design act as "technological text books", so many design and construction elements are revealed to show how the building functions. Finally, it is energy-efficient and formally expressive design.
