- Jesse Reiser and Nanako Umemoto run the architectural firm Reiser + Umemoto in New York. Reiser teaches at Princeton and Umemoto teaches at Penn. - The firm designs projects at various scales from furniture to buildings and landscapes. They approach each project as continuing their inquiry into relationships between architecture, territory, and distribution systems. - The document discusses the O-14 tower located in Dubai, which has a concrete shell facade with over 1,300 openings that functions as a sun screen and structural exoskeleton.

Reiser + Umemoto,
Jesse Reiser is currently an Associate Professor of Architecture at Princeton
University. Nanako Umemoto is currently a Visiting Professor at the University of
Pennsylvania
Recognized architectural firm, has built projects at
a wide range of scales: from furniture design, to
residential and commercial structures, up to the
scale of landscape design and infrastructure.
The firm approaches each project as the
continuation of an ongoing inquiry, delving
into relationships among architecture, territory
and systems of distribution.
By working on projects of varying
scales, from the architectural to the regional, the
firm has developed flexible strategies and
techniques that seek to open structures that
are now ossified and to integrate domains.

3. The O-14 tower is located on the Business Bay in Dubai, an
extension of the Dubai Creek.
The bay comprehends a diverse collection of postmodern towers on a
tabula rasa, an artificially created landscape.
Almost all towers are situated on the waterfront. The urban plan
prescribes a plinth of four floors and a superimposed tower.
At the side of the main access road the plinth is set back, at this
point the tower is completely
Business Bay,
Dubai
The tower is built as a generic office tower with a free
floor plan and no users yet in mind.
The tower seems unreasonable expensive and
as a result of the
crisis, the tower is at the moment empty and for sale.
Other hand the design comprehends distinguishing
elements like the concrete shell, the free form facade
and the high quality standard

4. The tower is composed of a four floor parking basement, a four story
plinth with a tower superimposed on it. On top of the tower is a mechanical
space.
The floor plan of the tower is a squeezed square, with an elevator
core in the centre.
The facade comprehends a casted shell with over 1,300 openings,
creating a mesh-like effect.
The shell functions as a structural exoskeleton and filters the light
entering the building. A meter behind the shell is a floor to ceiling glass facade.
The space between the concrete shell and the glass facade works
according to the chimney-effect: the heated up mass of the concrete shell and
the glazed windows are ventilated away instead of passed on to the interior.

diagrid. Diagrids are nowadays state of the art in
skyscraper design.
The density of the openings in the shell is
very high.

5. SPACE DISTRIBUTION
A podium that contain parking, with street-
level arcades linking to retail shops and
building lobbies.
The shell, which Reiser refers to as an
atectonic lacks any break in its surface,
including expansion joints. But the hole-ridden,
contoured slipcover of concrete required a
dense basket weave of rebar its underlying
structural tectonic,
The place parking underground on this
34,000-square-foot site and have a two-
story elevated podium wrap the tower on
three sides to accommodate more office
space and a restaurant.
The hole-ridden, contoured slipcover of concrete required a dense
basket weave of rebar its underlying structural tectonic in reiser's words.
The team tied the rebar at intersections with stirrups in the zones of
high stress, creating a diagrid with 40 percent openness

8. THE CONCRETE SHELL
The concrete shell is 40cm thick.
The shell is not only the structure of the building, it acts as a
sunscreen open to light, air, and views.
The 1300 openings on the shell modulate depending on structural
requirements, views, sun exposure, and luminosity.
The pattern is not based upon the program of the interior, since the
program is not fixed.
The openings 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.

10. 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

then cast around this fine
meshwork of reinforcement
and void forms resulting
in an elegant perforated
exterior shell.
