Labirentten geçen havanın bina içine iletilmesi/Labyrinth recovered air supply into the building
circulation of air that reaches the flexible office spaces is transported via pipes
embedded within the reinforced concrete floor slabs. When the air reaches
the chilled beams it is released to the space. Because the labyrinth is placed
underground it maintains less deviations in temperature maintaining the
annual average temperature typical of the region.
Further environmental design considerations can be seen in the façade.
Although the building has a transparent shell, it is covered with a steel mesh
that acts like a second shell. It was designed by testing the results of the
seasonal solar orientation and energy models.
The buildings structurally expressive system of reinforced concrete and steel is
used to create large spaces to accommodate the flow of air. The central atrium
with its transparent roof provides natural ventilation with the automatic port
controllers on top by the principle of regulating the uptake of air resulting
from the chimney effect. Any loss of energy is minimized by the circulation of
air through these types of heat recycling devices. In this way, solar heat and
the energy needed for cooling is minimized. Further environmental systems
includes pergolas that create a comfortable and usable exterior space on the
upper levels shading the terrace of the rooftop lounge, a roof that houses
additional mechanical systems for the heating and cooling of the building
including hot water pipes and photovoltaic panels, energy saving LEDs, waterefficient sanitary elements, storage of rainwater/gray water and regional plants
used for the landscaping as they consume less water.
Overall, with its TCA Headquarters Building, Avcı Architects brings together
many complex elements with an organized functionality, spatial aesthetics
and structurally expressive architectonics weaved elegantly together in the
same physical environment. Through the merger of structure, material, the
integration of the building system with the building mass and the holistic
approach to energy efficient design, they are able to set a high standard for
construction in Turkey for the sector and building in general.
