BLOG: Beyond energy efficiency - ROI for sustainable data centres

Peter Halliday | May 3, 2013
What are the challenges of operating energy efficient data centres and how operators can increase energy efficiency by adopting green practices at the infrastructure level?

Limiting energy loss from installed equipment

With a monitoring system that allows data centre operators to observe the exact amount of energy consumed in the facility, as well as the data centre's energy consumption trends, energy loss on installed equipment is quickly identified for prompt rectification. This minimizes any unintentional loss of energy.

Decreasing operating energy requirements

New technology and design features in data centres allow for higher internal temperature and humidity set points that do not affect the performance of IT equipment. This greatly reduces the demand load for cooling and cuts down operating energy demand.

Increasing power usage effectiveness

With power monitoring devices and communication-capable circuit breakers, that reliably and precisely monitor power at strategic points, operators are able to monitor power consumption patterns in real-time. Communication-capable circuit breakers increase the transparency in power distribution by transmitting current status, alarm signals and threshold warnings. Power usage strategies can then be adjusted and corrective actions taken to ensure optimal power usage.

Green steps in Singapore

As Singapore grows to be a data centre hub for the region, the need for energy efficient data centres will be critical as energy resources are limited. Data centres that are energy efficient at the infrastructure level will result in optimized performance, without compromising on environmental sustainability, which will lead to lower operating costs.
