Quick wins for Information and Communication Technologies

Quick Wins Lighting Logo
Information and Communications Technology (ICT) includes computing, imaging and business communications infrastructure equipment. Substantial savings can be made by ensuring that ICT systems, networks and devices are as efficient as possible. For data centres there are two basic approaches to increasing data energy efficiency: reducing energy consumption and improving cooling efficiency.
  • Do not over cool server rooms check with suppliers for the ideal temperature for the equipment
  • Create hot and cold aisles by arranging the servers in the data centre front-to-front and back-to-back
  • Install variable-speed fans and pumps and use high efficiency models
  • Exploit free cooling during cooler weather by using air/water economisers
  • Integrate performance per watt metrics into the procurement decision-making process
