Reducing waste.
WHAT WASTES COOLING
Hot and cold air mixing Missing blanking panels Perforated tiles in the wrong places Obstructed airflow Running colder than necessary Cooling unused equipment
WHAT CONTAINMENT ACHIEVES
Cold air reaching intakes without mixing, which allows higher supply temperatures and less energy.
WHAT RAISING SUPPLY TEMPERATURE ACHIEVES
Substantial energy savings, within equipment tolerances.
WHAT TO ESTABLISH FIRST
That air separation is good, before raising temperature.
WHY
Raising it with poor separation creates hot spots.
WHAT ELSE HELPS
Sealing floor openings Removing disused cabling obstructing airflow Removing decommissioned equipment
THAT LAST ONE
It consumes power and cooling for nothing.
WHAT TO AUDIT
Which equipment is actually in use.
WHAT TO MEASURE
Cooling energy against computing energy.
WHAT TO REVIEW
Tile placement and containment, after any layout change.
WHY
Layout changes routinely break airflow arrangements nobody rechecks.
