. The building is composed of a tower and a podium comprising two symmetrical wings. The tower's almond-shaped plan and curving forms gives the building a distinctive shape that helps keep it cool, with the narrow ends facing the east and west where heat gain is greatest. A high-performance curtain wall, made from silver, butt-jointed reflective glazing, also helps control heat gain while concealing the three main mechanical floors to create a seamless facade. At the top of the tower, an inverted arch is spanned by a glass skybridge housing a public observation deck. The large opening allows the building to rise higher than the height limit—30 occupied floors—mandated by local laws. Its design was inspired by iconic structures from around the world, including the

Structure

The Kingdom Center is built on a four-meter-thick, 3,100-square-meter raft foundation. Its structure consists of two systems:

columns, beams, and core for the first 180 meters, and a tubular steel frame structure for the building's remaining height.

Mechanical systems

A multi-part mechanical system was created to accommodate the building's mixed-use program. The tower is cooled by a central chilled water plant, supported by a thermal energy storage system that provides 5,000 tons of cooling capacity. This storage system is used during the hottest hours of the day, allowing the building to shift cool-air production to off-peak hours when electrical demand is lowest. The podium structures are served by separate mechanical systems designed to accommodate the needs of the building's unique programs. Systems used to cool these spaces include
