High Cost but Low Value : 

High Cost but Low Value £1 spent on results in 45p on service delivery Considerable wastage exists within the 45p spend Opportunities for cost / performance improvement at all levels

Opportunity Overload :

Definition : 

Definition Data Centre Energy Efficiency Management is the organisational structure, procedures, processes and resources required to implement an Energy Management System (EnMS) in the data centre.

Scope of Influence : 

Scope of Influence

Structure of Data Centre Energy Efficiency Management : 

Structure of Data Centre Energy Efficiency Management Conforms to standard management practice (PDCA) Aligns to ISO, CEN and BSi standards methodology

PLAN : 

PLAN PLAN CHECK DO ACT Conduct Assessment and produce Gap analysis Determine programme of change Assign resources and timescales

DO : 

DO PLAN CHECK DO ACT Implement defined programme of change

CHECK : 

CHECK PLAN CHECK DO ACT Monitor and measure progress against original design Report on results

ACT : 

ACT PLAN CHECK DO ACT Modify activities to meet requirements of original plan Take actions to continually improve implementation

Implementation : 

Implementation Implementation follows the PDCA methodology Assessment is the first step Re-assessment should not be within 9 months
