Online SAS - data centre in Vitry sur Seine, France

• Datacenter is using outdoor vegetable oil-immersed transformers

• Only one stage of power transformation (20kV to 410V) in order to optimize efficiency and reliability,

• Cooling system is using outdoor dry-coolers in closed cooling circuit.

• Chilled water system is using a specific water temperature 9°C-19°C with 10°C water temperature drop difference. This specific water temperature permits to double all cooling exchange with the same water volume.

• High free-chilling capacity using heat exchangers between dry-coolers and chilled water can be used in a ‘mixed ‘ configuration (chillers and free-cooling) between 14,5°C to 4,5°C outdoor and in ’absolute‘ configuration (free-cooing only) on outside temperature below 4,5°C

• All the data center is using cold-aisle containment by default in order to get a return air to CRAC at more than 31°C

• PUE = 1.358 May 2013

TISSAT SA – data centre Walhalla in Castellon, Spain

An advanced structural design (e.g. using the Hot Aisle

Containment System “) solving the tradeoff between the high

availability needs of Tier IV DC and the reduction of energy

consumption.

Construction of an eco-efficient building.

Generation of primary energy and cooling with Tri-

generation.

Limitation of the power lost with the use of UPS allowing

99.9% of energy use.

Using the air conditioning condenser for rationalizing energy

consumption of air conditioning.

water-cooled DX

• Dry air coolers inside the plant room

• Variable speed pumps and fans

• Generator installed on the rejection side of the dry air

coolers

• Reuse of waste heat

• 250kW data centre

• Design PUE of 1.2

• Removed equipment from and turned off old inefficient AC

United Nation Support Base – data centre in

Valencia, SpainSolar panel installation Phase A (February 2012) 700 solar panels 280 Watt each (196 KW peak, 300 MWh

per year), Phase B (September 2014), 1080 solar panels 300 Watt each (324 KW peak, 500 MWh per year)

UPS in power Efficiency boosting mode Estimated savings: Around 350 MWh per year

PVC Curtains in Data Center Cold Aisle

Free cooling System Hours of free cooling: Around 3000 hours per year Estimated Annual Savings: 180 MWh

per year

Data Center Infrastructure Management Software Monitorization of power consumption of the different

electrical systems, main electrical panels and all the PDU located in the racks.

An automatic light control system has been implemented in order to switch off unnecessary lights in the Data

Center out of working hours.
