Located in the future Linkong Economic Park adjacent to Hongqiao Transportation Hub and in close proximity to Shanghai City Center, the mixed-use complex, comprising commercial offices and high-rise retail, is slated to be an iconic development and a key attractor for the region. The project is defined by four main towers composed of elongated elements tied together by a sinuous retail podium, walkways and bridges. Thornton Tomasetti provided façade engineering services, including the rationalization of the external surface geometry of the building ends to minimize the use of aluminum panels with double curvatures.
The envelope design is driven by high-performance thermal and acoustics criteria as well as the architect’s aesthetic requirements for a minimal and transparent façade. The building envelope consists of a fully unitized curtain wall system, which is a cost-effective and efficient solution to the large quantity of repeating façade elements that are required for the project. This solution also facilitates quality control as units are assembled off-site under factory controlled conditions, allowing for reduced work, simpler installation and greater on-site safety.
Sustainability features of the façade system include double-glazed units with spectrally selective coatings, thermal breakers and high performing insulation materials. Furthermore, external louvers at all levels are designed to minimize solar gains, mitigate glare and provide sun shading to the users which optimizes occupant comfort.
