square feet of office space for the Dubai Business Bay O 14 is located along the extension of Dubai Creek occupying a prominent location on the waterfront esplanade O14 is sheathed in a forty centimeter thick concrete shell perforated by over 1 300 openings that create a lace like effect on the building s faade The concrete shell of O14 provides an efficient structural exoskeleton that frees the core from the burden of lateral forces and creates highly efficient column free open spaces in the building s interior The future tenants can arrange the flexible floor space according to their individual needs The shell is not onl　y 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 The holes are achieved by introducing computer numerically cut polystyrene void forms into the rebar matrix and sided with modular steel slip forms prior to the concrete pour Super liquid concrete is then cast around this fine meshwork of reinforcement and void forms resulting in an elegant perforated exterior shell The project has generated extraordinary international interest in the architectural press as it is among the very first innovative designs to be constructed among a sea of generic office towers that have come to be the standard in Dubai s current building boom O 14 was recently featured in Impossible City an hour long television documentary about the recent growth in Dubai which was produced by CBS News and aired in the U S on the Discovery Channel in October 2008 Currently the first 20 floors and exterior shell of O 14 have been cast and the building is expected to be completed in Fall 2009 노출콘크리트 표면방수및 보호제로서 콘플로아 0 14 tower by Reiser + Umemoto콘플로아는 노출콘크리트의 보호제및 방수재로서 사용시 노출콘크리트의 수명과 아름다움을 오래오래 보존하는 기능이 있습니다 콘플로아 홈페이지 http www
