four keys for assessing the financial value of an IT energy policy

Share

Assessing the financial value of projects developed in the context of an IT energy policy requires a few best practices:

1) analyze as much equipment as possible 

Assessing a wide range of equipment helps make the project more appealing for decision-makers. Depending on the initial audit scope, it may be necessary to expand or extrapolate results over a larger scope.
 

2) evaluate all potential scenarios

Many different scenarios are available for energy-saving projects. It’s important to assess the savings generated by each scenario:

  • energy management software (savings generated by night and weekend shutdown of office PCs)
  • equipment update
  • virtualization
  • overhaul of IS architecture
  • combination of several different solutions
     

3) assess indirect energy savings

For each of these scenarios, it’s also important to consider any potential indirect energy savings:

  • optimizing the costs of managing IT equipment
  • reduced cooling costs for IT infrastructure
  • reduced CO2 emissions expressed in financial savings
     

4) perform post-launch analysis   

After launching any energy savings project, it’s important to analyze actual energy savings in order to compare this figure with the project’s initial estimates. This will help validate and enact an effective IT energy policy.
