Jesse Reiser + Nanako Umemoto: O-14 Dubai
O-14
project by RUR Architecture PC is a 22 story tall commercial tower located in Business Bay in Dubai, The tower's concrete shell not only is the
structure of the building but also open to light, air, and views from the
façade. The
facade is constructed from the extremely fluid perforated concrete of 400 mm
thick. Reiser and Umemoto uses computer to numerically
cut polystyrene void forms into the rebar matrix, and sided with modular steel
slip forms prior to the extremely fluid concrete of 400 mm thick then
flipped the skin to offer a new economy of tectonics and space. The space is nearly one meter deep between the shell and the main
enclosure which creates a so-called “chimney effect”, the shell structure
sustainable performance of the design which provides the passive cooling
effects that allow hot air to rise and effectively cools the surface of the
glass windows behind the perforated shell, this strategy achieves the cooling costs by 30%.
The organisation of the
design was well thought through, exoskeleton diagrid provides the structural
integrity to the building, which means adding material locally where
necessary and removing away where possible. The
pattern design is a combination of a capillary branching field, gradients of
vertical articulation, opacity, environmental effects, a structural field, and
a turbulence field. Both Reiser and
Umemoto focuses the project base on materiality, finding a way for the geometry
and materials to work with each other to develop within the space. The exoskeleton diagrid is a management of relationship
between the building geometry and its material behaviour. Architects and engineers consider materials as an
important core to sustainability, which is related to Picon’s quote “with the
research on composite and smart materials and the tendency to solve more and
more problems at the level of material design rather than structural design”
(Picon 2010, p.145).
The O-14 materiality as
Resier keenly interested on the material effect and the abstraction materiality
that isn’t just about articulation of parts or transmutation of parts but it
would be the underline structure that would get express into the concrete.
