DCO² only uses 11% of the IT load to cool and secure the services.
This very low overhead is achieved by using the local weather to cool the datacenter and using optimal UPS systems to secure the power infrastructure.
Every powered device is checked on power consumption, and -where possible- is only powered on when needed.
The overall power usage of the building is even lower when you take into account the 430 kVA solar plant that is placed on the roof of the building. This roof is generating about 11% of the total energy need of the datacenter.
The datacenter is original built for a PUE of 1,06 and we have effectively achieved this in our datacenter.
After 2 years we changed the cooling from direct free air cooling to an indirect free air cooling system. Its means an actual PUE of 1,11
