# Facility Load Calculator > Facility Load: Facility kW = IT + cooling + distribution losses + other. Methodology stated, your own inputs only. Page: https://freecalculator.tech/tools/facility-load-calculator Last reviewed: 2026-10-20 ## Formula Facility kW = IT + cooling + distribution losses + other. - 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). ## Inputs - IT load - Cooling plant electrical load - Power distribution and UPS losses - Lighting and other building loads (blank = none) ## Worked example: Hall totals 160 kW IT, 64 kW cooling, 16 kW losses, 4 kW other. 1. 160 + 64 + 16 + 4 = 244 kW. 2. 244 ÷ 160 = 1.525. ## 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. ## 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. ## Sources - The Green Grid — https://www.thegreengrid.org/en/resources/library-and-tools/20-PUE%3A-A-Comprehensive-Examination-of-the-Metric ## Cite this page - APA: Free Calculator.
