Audit Energy Consumption

Systematically assess where and how energy is consumed across a facility or operation to identify waste, prioritize upgrades, and establish a measurement baseline for efficiency programs.

Why This Is Best Practice

Adopted by: U.S. Department of Energy Better Buildings program (covering 13% of U.S. commercial building space), EPA ENERGY STAR (certified 40,000+ buildings and plants), EU Energy Efficiency Directive (mandatory energy audits for large enterprises), ISO 50001 certified organizations in 170+ countries, ASHRAE (professional standard for commercial auditing). Impact: ASHRAE research shows Level II energy audits identify savings opportunities averaging 15–30% of energy costs. EPA ENERGY STAR buildings use 35% less energy than typical buildings (EPA 2023 data). ISO 50001 certified organizations achieve average energy intensity improvements of 10–15% within 3 years. DOE Better Buildings challenge participants saved $15 billion in energy costs and 7.4 quadrillion BTUs over 10 years. Most organizations reduce energy costs by optimizing what they already have — HVAC scheduling, lighting controls, equipment setpoints — before capital investment. An audit quantifies the opportunity in each system so resources target the highest-ROI improvements first. Without a baseline audit, efficiency programs lack the measurement foundation to claim savings or set credible targets.
