“The building, 728 feet long, 282 feet wide, six stories high, presents an impassive façade to the world with its rather bland curtain wall of glass and aluminum.”

Guided by Dubai’s hot, sunny and windy desert climate, the architects designed a tiered façade that prevents wind vortices from forming, a curved curtain wall that reflects direct sunlight, and an innovative “sky-sourced” ventilation system that distributes cooler, dryer air to reduce air-conditioning usage.

The centerpiece of Shigematsu’s design is a new three-story gallery building, sheathed in a glass curtain wall.

The type of bulletproof glass needed to resist a high-powered rifle is not the same stuff you see at a liquor store: It costs upwards of $10,000 a pane, and it can run up to three inches thick, which would mean adapting the building’s mullions and adding thousands of pounds of new weight to the curtain wall.

Beijing Jiayu Door, Window and Curtain Wall Co also flagged risks this week, saying it turned in a loss of up to 1.4 billion yuan last year, thanks to receivables from Evergrande that are likely to go sour.
