CITY’S KALEIDOSCOPE: a cylinder mirroring the city, capturing its ever changing scenery. As the wandering citizen looks into one end, light enters to create colourful patterns portraying the dynamics of the capital. A place where ‘Beauty’ is captured, where it is held into a defined ‘Urban’ Architecture, an identifiable place visible from all standpoints. A materialized information space that renders the abstract a touchable reality. The City kaleidoscope is an opportunity to interconnect the various qualities of Warsaw public spaces, it opens up the possibility for a new and contemporary understanding of a cultural centre. an open Icon. CEILING VIDEO PALIMPSEST: On the semi spherical roof there will be displayed information about current events in Warsaw. The multiplied projections will create patterns and compositions like a kaleidoscope, visible from all around the area. the building will keep its original architecture and transparency and in the same time the new treatment of the ceiling will allow for an all new face. CULTURAL BANK: The mezzanine level will contain a multifunctional public space dedicated to give visibility to cultural events, debates and exhibitions regarding the city of Warsaw. Information, sounds and images of city events will materialized inside the rotunda and will become an interface that acts on the urban scale. The mezzanine is accessible independently from the bank, directly from the new public access at the level of the Metro passages. The space is flexible in its use, an open bar, a debate space, a place for exhibitions or for events. POLSKI BANK: Banking and public space are two functions with opposing safety and control systems. Accordingly, we propose to separate them and create independent entrances. The bank will be accessible from the three existing street level entrances. The technical components and back office areas will remain in the refurbished naunderground level. UNDERGROUND / OVERGROUND CONNECTION: The topography we suggest to surround our intervention can play a crucial role for the all area. On one hand it allows for the different functions, despite their disparity, to coexist and to have separate access points. On the other hand, the sloping public space on which the rotunda sits allows it to connect back to the public space ‘Underneath’. Tying up its link with the ‘Rotunda’ and giving it back to the City. Here, the notion of the ‘UnderGround’ is lost as the ground is multiplied through the interconnecting slopes suggested in the project. The various citizens are channelled into the ‘City Kaleidoscope’: the ones arriving from the public transport, the shoppers as well as the wondering dreamers are all invited to interconnect and meet under the Rotunda.
LEED CERTIFICATION: The building energy efficiency and overall performance will be significantly improved by sealing the building envelope and making the inside airtight and vapour resistant in order to reduce the energy needed to heat and cool the building. A double glazed façade will enable high thermal and acoustical insulation level. An automated blind system will prevent excessive solar irradiation in the summer period. LED lighting will be used to reduce energy consumption. Photovoltaic panels could be installed on the roof of the rotunda without being visible from the street level. Using the LEED principals will help maximize the efficiency of the operations while minimizing the impact on the environment.
DuPont SentryGlas will be used for glass walls and rails, taking advantage of the interlayer’s extra rigidity and toughness, to increase safety for people in and around the building and for higher treat levels for the bank. DuPont Corian will be mainly used in the project for interior floors finishing, details finishing and interior furnitures. Also the exterior cladding of the roof side and exterior square furnishing will take advantage of the high resistance and versatility of the Corian material. DuPont Tyvek breather membranes will control the airflow through the roof and Du- Pont AirGuard will be combined to achieve optimal thermal control and long-term performance in the roof restoration.
