The project was the result of a limited design competition, with a brief that placed a great emphasis on leading environmental design approaches. From the outset the project team was a multidisciplinary group, both international and local, which included Atelier Ten from London as environmental engineers. The completed building received LEED Platinum Certificate and is already regarded as a showcase of leading edge environmental design, which has raised the bar for designers and clients alike, not only in Ankara but the whole of Turkey.

1. Hot air in external environment goes from stacks into the labyrinth.
2. Hot air cools down naturally as it covers distance inside the labyrinth.
3. Air losing its heat reaches air conditioning stations according to conditions, if necessary it is further cooled down.
4. Air going through canals embedded in R/C slabs also cooling concrete mass reaches cold beams.
5. Cold beam depending on the need in the environment further cools down the air, releasing it into the interior.
6. Air heated up due to the impact of machines and people is collected in ventilation ducts and carried to heat recovery units.
7. The atrium at the core of the building with stack effect collects all heated air at the highest level, carrying it to heat recovery stations, again through ducts.
8. Thanks to the mesh and shade elements forming the exterior of the building, heat recovery is minimized.
9. There are also hot air pipes and photo-voltaic panels on the roof.
