Facility Load Calculator
Facility Load: Facility kW = IT + cooling + distribution losses + other. Methodology stated, your own inputs only.
In short
Facility Load: Facility kW = IT + cooling + distribution losses + other. Methodology stated, your own inputs only.
Formula: Facility kW = IT + cooling + distribution losses + other.
What this calculator does
Facility Load: Facility kW = IT + cooling + distribution losses + other. Methodology stated, your own inputs only. Worked example, questions and limitations included.
Use it to turn IT load, Cooling plant electrical load, Power distribution and UPS losses, Lighting and other building loads (blank = none) into a checked result you can compare, copy, or rerun with different assumptions.
The page shows the formula, a numeric worked example, and the assumptions that affect this data centers calculation.
Inputs and what they mean
- IT load
- — number value.
- Cooling plant electrical load
- — number value.
- Power distribution and UPS losses
- — number value.
- Lighting and other building loads (blank = none)
- — number value.
How to use it
- Enter each value in the unit shown next to the box (use the unit converter first if your numbers are in other units).
- Check the breakdown to see every intermediate step.
- Read the limitations before relying on the result.
Formula
Methodology: facility load components as broken down by The Green Grid for PUE.
Instant PUE from power is shown only as a guide — annual energy PUE is the reported figure.
No component share is assumed.
Facility kW = IT + cooling + distribution losses + other.
Inputs used: IT load, Cooling plant electrical load, Power distribution and UPS losses, Lighting and other building loads (blank = none).
Worked example
Hall totals
- 160 + 64 + 16 + 4 = 244 kW.
- 244 ÷ 160 = 1.525.
Reading the result
The headline figure is the main answer. Any breakdown underneath shows the parts that make it up, so you can check the working and see what changes when you adjust an input.
Limitations and assumptions
- Snapshot of power, not energy.
- Shared building loads must be apportioned by you.
- Results are estimates built only from the figures you enter. No electricity, fuel or gas price, equipment efficiency or benchmark is built in — tariffs vary by supplier, region and time, and equipment data must come from the manufacturer. Designs and installations must be checked by a qualified professional.
- The result depends on the values you enter for this facility load calculator; it does not supply missing rates, rules, prices, dates, or assumptions for you.

Common questions
Is there a target or industry average built in?
No. Results depend on climate, design, load and measurement point, so none is shown. Compare against your own history.
How do I get UPS losses?
Input minus output power at the UPS, or from the manufacturer's efficiency curve at your load. Check the formula, example, and limitations on this page before using the result for a real data centers decision.
Why is the PUE here 'instant'?
It uses power at one moment. Reported PUE should use energy over a year.
How do I use the Facility Load Calculator?
Enter the required values for IT load, Cooling plant electrical load, Power distribution and UPS losses, Lighting and other building loads (blank = none). The calculator applies the formula on this page and shows the main result with any supporting breakdown so you can check the arithmetic.
What formula does the Facility Load Calculator use?
Facility kW = IT + cooling + distribution losses + other. The visible formula section above lists the calculation path and the edge cases the page handles, so the result can be checked without relying on the form alone.
Can the Facility Load Calculator be used for exact decisions?
Use it as a calculation aid, not as a substitute for checking the underlying rule, contract, policy, or professional advice that applies to your situation. When a result depends on local rules, personal details, prices, or dates, enter those values yourself and confirm them before acting.
