The data center and electrical areas of the building, which includes white spaces, technical areas, and support areas for personnel, are vertically divided into two, with the half closer to Phase-1 designated as Phase-2, and the other half as Phase-3.
Although the zoning rights on the plot allow for more development, the white spaces are designed as 8 separate server halls with a single floor and a clear height of 5,10m to optimize both cost and electrical power requirements, as well as architectural and engineering solutions. In the design of the Phase-2 and 3 white spaces, unlike Phase-1, a side cooling method with a fanwall system is adopted. This system ensures more efficient distribution of cold air and energy savings.
The electrical areas are designed as two-story, and the support area, which includes the network operations center and office/lounge areas, is also planned as two-story on the facade facing Phase-1. Telco rooms are located in the middle of the ground floor, and technical volumes such as shelter, warehouses, and fire suppression system water tanks are located in the partial basement. The upper floor of the electrical areas and the mechanical area are integrated on the first floor of the building.
In the facility where the entire plot is arranged on a single level, the ground floor of the Phase-2 and 3 building is arranged at the same level as Phase-1, and level and continuous horizontal circulation is provided between all white spaces with the connection halls created between the two phases. The Phase 1 loading area is used for server entrances to the Phase-2 section, and an additional loading area is created in the area allowed by the plot setback distances for the Phase-3 section.
Horizontal and vertical user circulation within the building is provided by stair and elevator cores designed in accordance with Turkish regulations and NFPA conditions.
The majority of the structural system is designed as reinforced concrete, and the structure is divided into 3 sections with a minimum expansion joint line to minimize problems caused by structural movements. The beams spanning the approximately 20m span and 7,16m height of the white spaces, where columns are not desired, are designed as steel, and the loading area canopy, chiller platforms, transition bridges between Phase-1 and 2, and generator chimneys are also supported with steel elements.
All roof surfaces are designed as flat terraces to provide the most effective waterproofing, and water discharge is solved with a siphonic system that does not pass through the white spaces. Thanks to the flat surfaces of the roofs, chiller platforms can be placed on the white spaces, and satellite dishes can be placed on the mechanical area.
Cement-based panels are preferred on all solid facades of the building to match the texture with the Phase-1 buildings. To add dynamism to the very wide and monotonous opaque surfaces, the facade cladding is painted in two tones, concrete gray and dark gray, and the sections in these colors are separated by oblique lines.
The canopy covering the Phase-3 loading area and the desired canopy surfaces on the electrical area facades are integrated as a continuous line surrounding all facades and are covered with navy blue aluminum composite compatible with Phase-1.
The openings on the electrical area facades are covered with louvre surfaces that allow fresh air and equipment entry and exit. A steel construction framed screen consisting of louvres of the same quality is created on the west facade to obscure the view of the chiller platform located on the white space from a human perspective.
