After they are delivered, pre-built racks are left in the staging area to acclimatise to the temperature and humidity in the data center.
All doors in the building are three metres-high, including the goods lift door, to get pre-built racks inside the center.
The data center has three emergency power supply rooms, each equipped with a low loss transformer to take the power up into the data hall.
Each emergency power supply room can deliver 1.1MW power to different zones in the building.
Batteries are kept in a separate room, and they can support the emergency power supply for six minutes in the case that the main supply went off.
There are four IT rooms in the center to store servers, and four entry points at ground level that lead into the data rooms.
Technology company Server Choice has just started storing its data in Kao Data's London 1 center.
Outside air comes through the corridor behind this screen, in which a damping system enables a uniform flow of air in the room.
Air from the hot aisle is circulated through a heat exchanger to remove the heat without the need for a mechanical refrigeration system.
There are three outside generators that can provide 1.75MW of power each in the case of an emergency.
Each outside generator sits on up to 48 hours of diesel storage, and the company is looking at renewable sources of energy to power the engines in the future.
