Zaha Hadid Architects wins competition for Daxia Tower

Demarcating the centre of Xi’an’s business district, Daxia Tower’s gently curving silhouette is accentuated by layers of patterned glazing and dramatic atriums that bring natural light deep into its floorplates.

Creating a cascade of planted interior terraces that echo mountainside waterfalls, each atrium gives panoramic views over the historic city to the north and east, or the growing high-tech zone to the south and west.

Situated on on Jingye Road, the Daxia Tower will incorporate 127,220 sq. m of office space, along with additional functions to create a seamless integration between the new addition and the surrounding development zone.

Multi-storey atriums are designed around the building to bring natural daylight into the floorplates, while the interior planted terraces take cues from the mountainside waterfalls.

The integrated greenery also helps purify the air, fostering a healthier indoor environment. The structure is also adapted to the challenges of Xi’an’s temperate continental monsoon climate.

Optimized daylight and incorporated natural ventilation ensure high performance and low emissivity during the building’s lifespan. The glazed facades feature a thermal coating and insulation against low U-values to further reduce energy demand and increase efficiency.

The facades also include sensors and photovoltaic panels to enable energy generation. A rainwater harvesting system is planned to create a supplementary source of non-potable water, while an integrated recycling system will treat and reuse gray water.

A smart management system will monitor the energy consumption and environmental performance, as well as recognize patterns in occupancy, allowing it to adjust the interior conditions accordingly. Source by Zaha Hadid Architects.
