Beijing is one step closer to completing the world’s tallest atrium. The 190-meter-tall atrium is part of the Leeza Soho, a 46-story mixed-use tower under construction that recently reached level 20.

Zaha Hadid Architects designed the light-filled building integrated with energy-efficient systems and engineered to meet LEED gold standards, according to Inhabitat.

Shaped like a slim barrel, the 172,800-square-meter Leeza Soho is set within the Lize Financial District and will be well connected with the city thanks to its position above a subway interchange station and proximity to the city’s bus routes. Zaha Hadid Architects used the subway lines that run beneath the site as the basis for a diagonal axis that splits the tower into two halves connected via the central atrium.

“As the tower rises, the diagonal axis through the site defined by the subway tunnel is re-aligned by ‘twisting’ the atrium through 45 degrees to orientate the atrium’s higher floors with the east-west axis of Lize Road, one of west Beijing’s primary avenues,” the architects wrote.

The twist in the atrium allows natural light to penetrate into the center of all the floors and allows for a diversity of views into the city from all directions. To maximize energy efficiency, the glass curtainwall system is constructed with double-insulated low-e glazing units. High-tech insulation, self-shading and use of an advanced 3D BIM energy management system with real-time monitoring will help create a comfortable indoor environment year-round.

The tower will target LEED gold certification and also includes heat-recovery from exhaust air, high-efficiency pumps and fans, chillers and boilers, low-flow rate fixtures, gray water flushing, high-efficient air purifiers and low VOC materials.

Leeza Soho will reach its full height of 207 meters in September. The tower is slated for completion in late 2018.
