Best Practice

ICT Energy Efficiency Working Group


Energy Use in ICT

Site assessments by SEAI Advisors across the country have shown Information Technology services to be:

  • A significant uncontrolled energy user
  • Responsible for relatively high night-electricity usage in large public buildings
  • Driving cooling demand as IT service provision increases.

Potential Energy Efficiency Opportunities

There are several technology and management upgrade opportunities that are appropriate in ICT:

  • Reduced cost of energy - As office equipment runs more efficiently, there will be a drop in energy consumption — meaning a reduction in running costs too
  • Longer useful life of equipment - Equipment that operates at full power for less time will usually last longer and have less chance of overheating and failure
  • Increased mobility - Increased use of laptops allows for more flexibility and mobility.
  • Reduced mechanical ventilation requirements - Equipment on standby mode runs at lower temperatures which reduces the need for mechanical ventilation and cooling
  • Protecting the environment - Lower energy consumption means reduced carbon emissions which are a major contributor to climate change.
Key Issues

ICT is a key service within the Public Sector, with principal topics including:

  • Server virtualisation
  • Cooling demand
  • Best practice in day-to-day operations.
  • Identification and billing of energy usage

SEAI is facilitating an ICT group, bringing together principle stakeholders and leaders in energy efficiency to develop methods to improve energy efficiency. 

Membership includes:

  • Local authorities
  • National and international experts on data centres, green IT and cooling
  • Key stakeholders in Public Sector IT
  • SEAI
Planned Outcomes. Planned Results. Planned Savings.

The Working Groups developed a number of work streams to support energy efficiency in ICT services including:

  • Best practice guides
  • Identification of barriers to widespread replication & their respective solutions
  • Identification of training requirements for stakeholders.
  • Design for energy efficiency – Guideline requirements and specifications.
  • Case studies of work completed
  • Summary report of policy recommendations.
