Equator Tower | REX

A retractable sheath to cover the 80 story tower dubbed as Equator Tower at Kuala Lumpur, Malaysia is the latest addition to the world of brise soleil. Located near the equatorial line, the tower is subjected to radiation from all four sides, hence requiring an ingenious method of controlling the incident radiation without obstructing the beautiful views it has to offer. Designed by REX, New York, this is one of the top five finalists for a 173000 square meter proposal for a corporate space. The tower features offices and commercial space with inter dispersed leisure areas on a 1.5 m planning grid. With a 12.5 m wide floor plates, 4.2 m floor to floor height and 2.9 m floor to ceiling height, the tower offers high area efficiency.

There are 3 mechanical floors leading to a more slender service core and an efficient service riser scheme, the total area saved is used to provide two intermediate sky lobbies, observatory and podium lobby, all connected by a double-decker elevator system. The building functions like an office machine with flexible office spaces, high daylight penetration and use of small dispersed columns throughout the perimeter. The ceiling to floor span is mullion free, with triple glazed IGU clear glass, giving clear views of the Malaysian skyline. THe radiation control is in the form of PFTE coated glass fiber reinforced sunshade stretched on tensile cables. Silver exterior coating rejects heat and black interior coat frames views and provides 80% opacity. The material makes the skin lightweight, strong and highly nonreactive hence making it long lasting. The shade can exist in two states: Fully open stretched from the mechanical floors to the sky lobbies, on sunny days. Retracted to the mechanical floors at nights and overcast days to reveal the rigid core. Giving an overall effect of an intricate veil designed to be both protective and private without compromise on aesthetics.
