Chicago, Illinois, US
Nunnmps, Chicago is an information technology system development office. The site is located in South Chicago, bordering Lake Michigan.
project consists of a 50,000 square meter design and research studio in
addition to surrounding public open space and natural landscape. One third
of the building encompasses the design and research studios and support
areas. Since the studio projects are of a strategic nature and highly
confidential, the building is lifted above ground, high above the crowns
of trees, floating like clouds, overlooking the distant skyline. The
remaining two thirds of the office space exist within its subterrain. It
accommodates a reception area and a large open administration office with
mushroom-like cores penetrating the ground to connect both parts of the
Uncommon for a commercial development, the project contributes to its community on a multi-faceted level. It redefines the notion of 'work and place', 'city and landscape' and integrated culture and community.
The building is oriented such that the open portions of the façade are mainly directed to the North.
the ground floor, the glazed facade to the south is passively shaded by
the cantilever concrete slab during the summer time. The thermal masses of
shaded concrete provide natural chilling for the interior spaces during
the hot seasons. In the winter, the low sun angle allows storage of energy
within the thermal masses, warming up the interior spaces.
The office parts, elevated from the ground are wrapped with translucent ETFE. The surface absorbs glare and harsh direct sunlight, creating a thermal buffer zone in between the external and internal spaces. The room temperature is regulated by chilled ceilings and chilled beams.
All air in-take is transferred through underground conduits. The ground temperature is cooler than the outside temperature during the summer months while the ground temperature is warmer than the outside temperature during the winter months. In a natural balance state, the in-take air is pre-chilled or pre-warmed by the ground. The system makes use of sustainable energy rather than high energy consumption appliances such as air-conditioning units. This sustainable system pre-chills the air to desirable room temperature in the summer and pre-warms it in the winter. Heat-exchange between in-take and out-take provides additional temperature regulation by recycling the energy from the out-take air.
