Green Data Center

PCCW Solutions’ data center environmental management system has been certified to the ISO 14001 standard. All facilities such as UPS, air-conditioning, generators and E&M services feature the latest energy-saving and environment-care technologies available.

Our generators are extremely environment-friendly in terms of low levels of gaseous emission, smoke discharge and noise, while UPS batteries are air transport compliant and chillers generate low levels of noise and use environment-friendly refrigerant with zero potential for ozone depletion.

The cooling system has been designed to run at the highest level of efficiency. A hot aisle/cold aisle rack layout design, coupled with a high raised floor and minimal facilities underneath, provides a high volume of uniform cold air moving up the cold aisle, passing through servers and moving to the hot aisle before returning to the CRACs. Cold air does not mix with hot air and is able to circulate servers smoothly. The air output of the cold aisle can be adjusted to meet the cooling requirements of adjacent racks. Increasing cold aisle output caters for higher heat density racks, while lowering cold aisle output for lower heat density racks saves energy.

The quality of our overall energy-saving design enables our data centers to achieve best power usage effectiveness and helps our customers benefit from low electricity charges.
