An ASHRAE Level 2 energy audit in Kentucky typically costs $0.10 to $0.50 per square foot — roughly $5,000 for a 25,000 sq ft office and $25,000+ for a large industrial facility. Here's the full breakdown, what's included, and how the audit pays for itself.
Short answer: An ASHRAE Level 2 energy audit in Kentucky typically costs $0.10 to $0.50 per square foot, or roughly $5,000 to $25,000+ depending on building size, complexity, and how many systems are audited. Most commercial buildings recover the audit cost within the first 12 months of implementing the recommended measures.
Below are typical price ranges for Kentucky commercial and industrial buildings, what's actually included at Level 2, and how audits are typically financed.
Cost drops per square foot as buildings get larger because fixed engineering time is spread across more area. Cost rises for buildings with unusual systems — process loads, cleanrooms, 24/7 operations, or multiple utility meters.
ASHRAE defines three audit levels. Level 2 is the sweet spot for most Kentucky commercial buildings — enough engineering to make capital decisions, without the cost of a full investment-grade audit.
Level 2 gives you engineering estimates good enough for planning. It does not include long-term data logging, hourly simulation, or the M&V plan required for performance contracting. If a lender or ESCO requires guaranteed savings, you'll need a Level 3 investment-grade audit — usually $0.30–$1.00 per square foot.
For a typical 50,000 sq ft Kentucky commercial building spending $80,000–$120,000 annually on energy, a Level 2 audit usually identifies 15%–30% in cost-effective savings — $12,000–$36,000 per year. Against a $10,000 audit fee, that's a payback measured in months once the first measures are implemented.
Common Kentucky-specific wins we surface: LG&E and KU rate optimization, demand-side management incentives, LED retrofits with paid rebates through the utility, and RTU right-sizing (most Kentucky commercial buildings are 20%–40% oversized on cooling).

An ASHRAE Level 2 audit in Kentucky typically costs $0.10 to $0.50 per square foot. A 25,000 sq ft office building runs about $5,000–$9,000; a 100,000 sq ft facility runs $12,000–$22,000.
Level 1 is a walk-through with utility bill benchmarking ($0.02–$0.05/sq ft) — good for triage. Level 2 adds a calibrated energy model, measure-level financial analysis, and a capital-planning report — the standard for making investment decisions.
Most Kentucky commercial buildings take 4–8 weeks from kickoff to final report: 1–2 weeks for data gathering, 1 week on site, 2–4 weeks for modeling, analysis, and reporting.
Yes. LG&E, KU, and Duke Energy Indiana all offer prescriptive and custom rebates for measures identified in an audit — commonly LED lighting, VFDs, high-efficiency HVAC, and controls. The audit report is often required documentation.
No. The audit is a planning tool. You choose which measures to implement, in what order, and with which contractor. A good audit gives you a prioritized menu, not a single mandatory package.
