REX architecture has unveiled designs for ‘equator tower’ in kuala lumpur, malaysia, an 80-storey structure primarily housing new office facilities for the region, but also including a diverse program of auditoriums, restaurants and bars, retail outlets and executive clubs. the design is characterized by an external sunshade, wrapping the entirety of structure, which can be retracted depending on environmental conditions.

as the name suggests, the building is located on the equator, meaning that it receives equal and direct levels of sunlight and exposure on each of its four elevations. consequently, the scheme’s retractable PTFE-coated glass fiber-reinforced sunshade ensures that offices are protected from glare, without compromising panoramic external views.

during the day the sunshade is stretched across the project on a tensile cable net, establishing the tower’s identifiable form. the design allows sections of the veil to be retracted when not exposed to the sun, or the entire shade to be removed on overcast days or evenings. it is imagined that the daily changes and transformations of the building and its shading device will become a spectacle in its own right, a new landmark for the kuala lumpur skyline.
