Standard Limits, Equations & Space Presets

ISO 50001:2018 Industrial & Facility Energy Management System (EnMS) engineering suite: production-normalized Specific Energy Consumption (SEC), reactive power capacitor bank compensation sizing (kVAr), annual CO2e footprint reduction, and ISO/IEC 30134-2 Data Center PUE.

Governing Equations & Physical Constants
SEC (EnPI)

SEC = E_kWh / Production_Output

Production-normalized Energy Performance Indicator per ISO 50001:2018 §6.4.

Q_c (Capacitor Bank)

Q_c = P_kW x (tan(acos(PF_1)) - tan(acos(PF_2))) [kVAr]

Required reactive power compensation bank to raise power factor from PF_1 to PF_2 and eliminate utility reactive penalties.

Delta_CO2e

tCO2e = (E_baseline - E_current) x EF_grid / 1000

Annual Scope 2 greenhouse gas reduction in metric tonnes of CO2 equivalent.
