Data Centre Demand Calculator
Estimate the annual electricity demand, water demand and household-equivalent consumption of a data centre from its rack count and server density.

Facility
Plain English summary
This facility could consume about 184 GWh per year — equivalent to 68,133.3 UK homes — and around 331.1 megalitres of cooling water if evaporatively cooled.
How This Calculator Works
IT load = racks × per-rack power × utilisation. Facility load = IT load × PUE (1.4). Annual electricity = facility load × 24 × 365. Water uses ≈1.8 litres per kWh for evaporative cooling.
What The Result Means
The figures size the facility's draw on the grid and water network, and translate it into homes-equivalent terms for context.
Limitations
Cooling method changes the water/electricity trade-off significantly; treat results as directional.
