A long but narrow profile houses the mixed residential-over office functions of this tower within a coherent but well articulated form. The floors are supported by four A-frame concrete “fins,” revealing the building’s structural system and internal organization. The building is oriented to reduce solar gain, and employs a system of sunshades on the exposed south elevation. The building takes a particularly interesting approach at its base, with only its structural fins and cores coming all the way to the ground, while the rest of the space opens up in an open-air shaded atrium with large pools which create a cool micro-climate around the tower’s entrances.

The Index presents a new environmental icon for the Middle East, showcasing important passive strategies of orientation, core placement and shading.
