Architect: Jesse Reiser + Nanako Umemoto Location: Dubai, United Arab Emirates Project year: 2006 Typology: commercial tower The shell is not only the structure of the building, it acts as a sunscreen open to light, air, and views. The openings on the shell modulate depending on structural requirements, views, sun exposure, and luminosity. The overall pattern is not in response to a fixed program, (which in the tower typology is inherently variable), rather the pattern in its modulation of solid and void will affect the arrangement of whatever program comes to occupy the floor plates. A space nearly one meter deep between the shell and the main enclosure creates a so-called “chimney effect,” a phenomenon whereby hot air has room to rise and effectively cools the surface of the glass windows behind the perforated shell. This passive solar technique essentially contributes to a natural component to the cooling system for O14, thus reducing energy consumption and costs, just one of many innovative aspects of the building’s design.
