The Leeza SOHO tower, designed by architectural giant Zaha Hadid Architects, opened in China earlier this week, boasting of the world’s tallest atrium winding within its form. Under construction on Lize Road in southwest Beijing since 2013, the building has 49 levels (45 above ground and 4 levels underground). The skyscraper anchors the new Fengtai business district, which is a growing financial and transport hub between the city centre and the recently opened Beijing Daxing International Airport to the south.
The 172,800 sqm tower aims to house small and medium-sized businesses in Beijing. Positioned as a flexible and efficient Grade A office space on a site adjacent to the business district's railway station, the structure straddles an underground subway service tunnel. Its position over this tunnel led the designers to split the building in two halves. The remaining expanse between these two volumes encompasses the full height of the structure, therefore creating the world’s tallest atrium at 194.15m. Leeza SOHO forms a spectacular civic space for Beijing, connecting to the city’s transport network directly.
In typical Zaha Hadid fashion, the building is enveloped in a single, glazed façade shell, while the rotating atrium connects its two volumes in a dynamic pas de deux (a ballet dance duet), with interlinking skybridges on levels 13, 24, 35 and 45. The mammoth atrium also acts as a public square for the business district, interlinking the tower’s areas and providing altering views to the city beyond, as it twists and turns. The sculptural form’s skylight floods the building with natural light, acting as a thermal chimney with an integrated ventilation system. This helps maintain positive pressure at lower levels to limit air ingress, and also provides an effective method of filtering the air inside the tower.
The concrete and steel tower is doubly insulated, with unitised glass curtain wall systems, helping draw air outside when needed. The public spaces of Leeza SOHO are shaded by its two halves, while the double-insulated low-e glazing effectively maintains a comfortable indoor setting in Beijing’s extreme weather conditions.
Championing the 3D Building Information Modelling (BIM) design, construction management and building operations, ZHA and SOHO China have embraced technology that minimises consumption of energy and added emissions. The building has also been awarded the LEED Gold certification by the US Green Building Council, as its advanced management systems monitors real time controls for energy efficiency. These systems also involve heat recovery from exhaust air and high-efficiency pumps, fans, chillers, boilers, lighting and controls. The top of the tower has a helipad, and also features an insulating roof with solar panels which harvest solar energy. The building also comprises elements of collecting water, low-flow rate fixtures and grey water flushing.
One of the most remarkable features of the skyscraper is that it fosters sustainable practises. The site has underground parking spaces for 2,680 bicycles, in addition to spaces for lockers, shower facilities and dedicated spaces for charging of electric and hybrid cars. Low volatile organic compound materials are installed throughout Leeza SOHO to reduce interior pollutants, while high efficiency filters remove particulates via the air-handling system.
