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
Participants

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.
