Project Description: This residential and office mixed-use building is 100-m high and has a square 28 by 28 m plan. Only part of the building is designed with a double-skin façade, which provides natural ventilation for most of the year. Office space occupies the lower part of the Eurotheum Tower while the top seven floors are used for residential purposes. 

The façade grid is 1350 mm wide and 3350 mm tall. Each unit, which is pre-fabricated off-site, consists of a 6-grid span, one-storey tall. The internal skin consists of thermally-broken aluminum frames and double-pane, manually-operated, tilt-and-turn windows. Power-operated blinds are located in the 34-cm-wide air cavity corridor. The external skin consists of single-pane, fixed glazing. Fresh air is supplied through 75-mm diameter holes in the vertical metal fins on each side of the glazing unit. Warm air is extracted through an exterior opening at the ceiling level. This opening is equipped with louvers to prevent the penetration of rain and is covered with anti-bird mesh.
