REX has been selected as one of five finalists for a 173,000 square meter proposal located near the equator in Kuala Lumpur, Malaysia. Dubbed as the "Equator Tower," the concept wraps a retractable, PTFE-coated, glass fiber-reinforced sun shade around a slender 80-story tower, blocking direct sun exposure from all four sides.
Each floor, comprised of 12-meter wide plates, accommodates office, commercial and leisure spaces, dispersing "extra amenities" — observatory, sky lobbies and podium lobbies — throughout the length of the tower. Mullion-free, floor-to-ceiling glass clads the resulting "office machine," needing only small columns dispersed throughout the perimeters.
The skin of the building drapes like a veil and exists in two states. During the day, the sun shade is stretched between the extra amenities and mechanical floors on a tensile cable net, "creating a high-performance, lyrical silhouette." The veil protects the offices' unobstructed views from daylight and glare, providing 85 percent opacity. 4.2-meter shingles allow air circulation and ease of retraction with a silver exterior coating that rejects heat, while a black coating on the interior enhances visual legibility of the cityscape.
On overcast days and at night, the swooping veil is retracted to the mechanical floors, revealing a rigid core that will undoubtedly become a spectacle within Kuala Lumpur's skyline.
