In China’s capital city, Zaha Hadid Architects has completed the Leeza SOHO tower, a 45-story skyscraper that boasts the world’s largest atrium at 194.15 meters in height. Designed to anchor the new Fengtai business district in southwest Beijing, the futuristic tower is wrapped in a double-insulated unitized glass curtain wall system that curves around its twisting, sculptural form. In addition to double glazing, the Leeza SOHO incorporates water collection, low-flow fixtures, a green roof , photovoltaic panels and other sustainable measures to meet LEED Gold standards. Set atop an underground subway service tunnel, Leeza SOHO was strategically sited next to the business district’s rail station at the intersection of five new lines that are currently under construction. The tunnel that bisects the tower splits the building into two halves; the resulting void in between has been turned into an atrium that acts as a new public square.

Indoor comfort is further achieved with the low-E, double-insulated glazing that ensures stable temperatures. To meet LEED Gold standards, Leeza SOHO features an advanced 3D BIM energy management system to monitor real-time environmental control and energy efficiency. Energy-saving measures include heat recovery from exhaust air; high-efficiency equipment such as pumps, fans and lighting; low-flow water fixtures and gray water flushing. Low-VOC materials were selected to minimize interior pollutants. Occupants and visitors can also enjoy plenty of bicycle parking, with 2,680 spaces available, as well as lockers and shower facilities. Underground, there are also dedicated charging spaces for electric and hybrid cars. + Zaha Hadid Architects Images by Hufton+Crow / Zaha Hadid Architects

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 currently under construction that recently reached level 20. Zaha Hadid Architects designed the striking light-filled building integrated with energy-efficient systems and engineered to meet LEED Gold standards. 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 . The architects write: “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.” Related: Zaha Hadid’s Guangzhou Infinitus Plaza focuses on environmental sustainability 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 this year. The tower is slated for completion in late 2018. + Zaha Hadid Architects
