2 Costly Mistakes Energy Auditors Make (And How to Avoid Them)

If you’re an energy auditor, your job isn’t just to find savings—it’s to find savings your client will actually implement.

But most auditors fall into two traps that kill both credibility and results: Not understanding how energy-using equipment really delivers the service.
Over-estimating savings (and losing client trust).

In this video, I break down why these mistakes happen, how they show up in real audits (think: missing 10+ savings opportunities in a single chiller system), and what you can do to avoid them.

You’ll learn:
Why “just swap for a more efficient chiller” thinking leaves money on the table
How to spot hidden savings in complex systems (air handling, controls, ventilation, and more)
The psychology behind over-promising savings—and how to get your numbers right
How to move from guessing to measuring, so your recommendations actually get implemented
If you’re serious about delivering investment-grade audits that drive real action, not just reports, this is for you.
