The project’s primary element is the roof, which<br />
consists of two parts: the green roof and the<br />
climatic dome. The climatic dome is a three-story<br />
glass atrium. The divided functional programs<br />
determine the shape of the roof. The interior of<br />
the dome must maintain a temperature that is 10<br />
degrees Celsius lower than the outside temperature,<br />
which results in condensation. By directing<br />
the elements of the surface structure towards the<br />
center, the design achieves its ‘centralized’ form,<br />
while a calculated assembly of various polygonal<br />
shapes allows for the architecture’s fluidity to be<br />
achieved. The roof structure, shaped like a diamond,<br />
is divided into sections using vertically installed<br />
steel pipes. By dividing the structure into two<br />
triangles, it becomes more flexible and allows<br />
for the construction of curving attributes to be<br />
achieved. The Climatic Dome is a cylindrical dome<br />
with a radius of 32 meters. In the absence of<br />
columns, the load-bearing points of the structure<br />
are located at the lower beams and the concrete<br />
beams at the top, the latter of which span between<br />
the steel roof and the green roof. The point where<br />
the two roof structures meet has been intentionally<br />
designed to serve as a vent for emergency ventilation<br />
in the event of a fire.<br />
The Climatic Dome was constructed using a prefabricated<br />
truss structure that was installed on site.<br />
The triangular openings were measured on-site after<br />
the truss installation was completed. This was done<br />
to ensure the most accurate measurements were<br />
obtained for cutting the glass that would be used<br />
as the building’s skin. The curved nature of threedimensional<br />
surfaces requires the triangular glass<br />
pieces to come in various sizes in order to deliver<br />
the intended appearance. The structural details of<br />
the dome’s design include parts that are developed<br />
and utilized to fasten the protruding glasses onto<br />
the circular steel member. The mechanism is responsible<br />
for holding together the laminated glass<br />
components that make up the outer layer of the<br />
building. The free-end details provide sufficient<br />
flexibility to accommodate the expansion and<br />
shrinkage of the material. To maintain a consistent<br />
interior temperature of 15 degrees Celsius within<br />
the dome, the design team had to devise a solution<br />
to prevent condensation resulting from the temperature<br />
difference between the inside and outside of the<br />
structure. To prevent such scenarios, extra attention<br />
was paid to the details of the glass panels’ joineries<br />
to ensure that materials with different temperatures<br />
are not installed adjacent to each other.
