ASHRAE Energy Audit
Definition
A systematic evaluation of a commercial building's energy use, conducted according to ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers) standards. ASHRAE defines three audit levels: Level 1 (walkthrough), Level 2 (detailed energy survey), and Level 3 (detailed analysis of capital-intensive projects).
Why It Matters for Your Business
ASHRAE-standard audits are the foundation of any serious commercial energy program. They identify efficiency opportunities ranked by cost, savings, and payback period. Many states, cities (NYC LL87), and lending programs require ASHRAE-level audits as a prerequisite for incentives or compliance.
Frequently Asked Questions
What is the difference between Level 1, 2, and 3 audits?
Level 1: Walk-through assessment, identifies gross inefficiencies, rough energy savings estimates. Level 2: Detailed energy analysis with site measurements, utility data review, and cost/savings estimates for all recommendations. Level 3: Investment-grade analysis with detailed engineering calculations for major capital projects.
Who can perform an ASHRAE energy audit?
Level 1–2 audits are typically performed by Certified Energy Auditors (CEA) or licensed engineers. Level 3 audits require a licensed Professional Engineer (PE). Credentials: ASHRAE Building Energy Assessment Professional (BEAP), AEE Certified Energy Auditor (CEA).
