Project Description: 16-storey towers with a 56-m high atrium in the center 

Each tower has a corridor double-skin façade with a single-storey interstitial space that is 90-140 cm deep and 20-m long. The interior façade has double-pane, low-E glazed doors that pivot every second bay. The exterior façade is 12-mm fixed safety glass. High-reflectance Venetian blinds are located in the interstitial space. Mechanical ventilation is provided during peak summer and winter hours. Chilled ceilings provide radiant cooling. The building can be naturally ventilated for 60% of the year.
