Energy and Risk Reduction Programme. Case study 2


Result

 

Brief

London facility that had already targeted energy reduction.

Recommended changes

PHASE 1:

  • Further air management – improved grille placement, blanking plates, and sealing of gaps in cabinets and floors
  • Increased CRAC set points and free cooling
  • Retrofitting of VFDs (to enable reduced fan speeds).
  • Reduced fresh air volume of AHU (previously over-supplied)
  • Lighting controls (previously lights were permanently on)

PHASE 2:

  • Semi-containment (25% of the facility)
  • Further increase of CRAC set points
  • Reconfiguring of CRAC fan speeds in UPS room and data halls

PHASE 3:

  • Semi-containment (remaining spaces)
  • Further increase of set points
  • Study of supply control and subsequent upgrade of control cards
  • Removal of unrequired under floor cabling
  • Solar gain window film
  • Study of pump controls
