The design by Zaha Hadid Architects aimed for a highly flexible usage concept and plenty of natural daylight. At the same time, the building meets the highest sustainability standards: it is pre-certified according to LEED Platinum and WELL Platinum as well as the Chinese 3-star Green Building Rating.
Complex glass facade

The sculptural glass facade is a central component of the design. The approximately 3,000 insulating glass units, some of which are three-dimensionally curved, each consist of four individual panes of glass with a total volume of around 150,000 square metre.
Both the inner and outer panes were designed as laminated safety glass. To ensure maximum light transmission, color-neutral Eurowhite base glass was used.
Three coatings ensure energetic and optical performance. Silverstar Superselekt combines basic sun shading with high light transmission, while Silverstar Sunstop NSP 50 was developed specifically for “The Henderson” as a particularly effective sun shading coating. The interference optical coating Luxar F, on the other hand, allows clear visibility at any time of the day or night.
Overall, the glass solution developed by Glas Trösch in close cooperation with the design team is tailored to the complex geometry of the building as well as the extreme climatic conditions.
The bottom line is a solar heat gain of less than 20 per cent, which significantly reduces the cooling load of the building.
Thanks to an average light transmission of around 35 per cent and very low residual reflection, the insulating glass units meet the highest standards in terms of user comfort.
