Schmidt Hammer Lassen architects has recently won the international architectural competition to design a 188 meter office tower in the financial district of central Warsaw, Poland. The 60,000 m2 high-rise building is to replace the existing ‘Ilmet’ building and will stand out as a modern landmark clearly identifiable in the Warsaw skyline by its unique elegant shape and appearance. The Jury was impressed by the high quality and innovation evident in the urban, architectural and technical concepts of the winning design. The future building will offer a number of attractive public areas and serve to complement the project’s prominent setting, as well as the entire neighborhood.
Sustainability was an important issue as the building is designed to reduce energy consumption with the goal of qualifying for the highest levels of sustainability certifications as BREEAM Excellent or LEED Gold status. More images and project description after the break.
The building consists of three individually stepped rectangular volumes with increasing heights towards the east. The façades create a subtle rhythm in the cityscape by slightly shifting inwards and outwards, and the inclined roof lines preserve optimal light conditions for the adjacent buildings.
The design of the building offers a spatial coherence between roof and street level. The lobby at street level, with its spectacular shaped ceiling, corresponds with the sloping shapes of the rooftops, making the building perceive as a sculptural object.
The open lobby allows the people of Warsaw to pass into and through the building, connecting the plaza and park in front of the building with the courtyards of the historical tenement houses to the south.
The building is designed to reduce energy consumption with the goal of qualifying for the highest levels of sustainability certifications as BREEAM Excellent or LEED Gold status. The modular façade system with floor to ceiling glass elements, provide high levels of transparency as well as full integration of sun shading and light reflection shutters. The sloped rooftops are equipped with photovoltaic cells and elements for harvesting rainwater. The total sustainability approach is a combination of intelligent building management and minimizing technical installations by using passive elements.
