Data Centre Cooling Calculator
Estimate the cooling a data centre needs. Set the IT load and target PUE, and get the cooling in tons, the total facility power, and the annual cooling-overhead energy and cost.
Total server/IT power draw — nearly all of it becomes heat.
PUE = total facility power ÷ IT power. Lower is better; 1.0 is the ideal.
to remove 100 kW of IT heat · add redundancy (N+1) and margin on top.
≈ 5,25,600 kWh/year of overhead (running 24/7). Every 0.1 off PUE is a real saving — which is why containment and efficiency matter.
A planning estimate. It assumes essentially all IT power becomes heat to be removed (1 TR = 3.517 kW), and derives facility power and overhead from PUE. Real design adds redundancy (N+1 or more), diversity, up-lift for future load, and detailed airflow/containment work — all specialist mission-critical engineering. Use this to frame the scale, not to size the plant.

Servers turn nearly all their power into heat, so a data centre is really a giant cooling problem — how precision cooling, hot-aisle/cold-aisle containment, CRAC/CRAH units and free cooling remove concentrated heat reliably, and why PUE is the number that matters.
