Designed for the fast-developing Qianhai District in Shenzhen, China’s south financial and technology hub, Golden Bridge Twin Towers is envisioned as a technologically innovative, interactive, resilient, and sustainable skyscraper. The site is adjacent to Qianhai Bay and the district park, drawing design inspiration from its connection to nature. At 200 m tall and 180 m tall, the towers have elongated masses with smooth corners and plan. The structures slope inward to optimize the solar and wind performance, while minimizing the impact of the dense urban environment and maximizing the views to the bay and park.
Two sky bridges – one near the ground and one at the top– connects the towers, providing unique amenities that help to maximize the program’s flexibility. Structurally, the bridges transfer wind and seismic loads between the two towers to improve their performance by reducing torsional responses and lateral displacements. Orientated around the sky bridges’ central opening is a central public gathering space with internal connections to multiple floors and external access to the rooftop terrace gardens. These spaces are visible from the shuttle elevators, creating an urban, iconic, interactive, vertical community space between the towers. This internal atrium extends upward, linking to the roof garden and sky farm protected by a building integrated photovoltaic canopy. At night, special lighting in between towers and on the skybridges give the towers and the neighborhood an added identity.
The building’s façade is carefully designed to optimize the solar and ventilation performance. Sunshades are deep and horizontal on the south to control the shading from high angle sun. The sunshades move gently around the building corners to reduce the depth in horizontal direction and increase the vertical direction to filter the low angle sun from morning and afternoon. A special glazing with dual photochromic and electrochromic property will be used to control the atrium solar condition with the maximized view out. Horizontal ventilated mullions provide the interior users convenient control of natural ventilation in the appropriate weather.
Golden Bridge Twin Towers uses multiple strategies for increased sustainability including high-performance façade with solar heat gain reduction, roof PV renewable energy generation, 60% water reduction, waste, and embodied carbon reduction, improved indoor quality with view, daylighting, and natural ventilation, on demand interactive office intelligent control, as well as access to the green and open space.
