This large 610-metre-high hotel complex, located in a strategic area of Riyadh, close to the business district and the city center, is a skyscraper that includes spa services, a sky bar-restaurant, and a conference centre. Its programme also incorporates three garden floors at strategic points of the building that function aerodynamically as windbreaks. As part of the conceptual design, renewable energy mechanisms are incorporated into the facade and the building, following a modular system of parametrically designed panels. Each panel incorporates turbines, and the diameter of the openings varies geometrically in order to promote natural ventilation in parallel with the cooling system that takes advantage of rainwater harvesting.
