How owners and CFOs should hear a plant constraint

Plant engineers feel capture velocity and fan curves. Owners and CFOs feel margin, cash, and risk. Both are correct, and both have to share a measurement basis before capital is locked.

Best practice for manufacturers: express facility constraints as (1) utility dollars tied to systems you can change, (2) throughput or quality at risk, (3) compliance exposure, and (4) capital that would be wasted if the root cause is geometry or balance rather than "more CFM." Typical opportunity bands of 10-25% only hold when the baseline is facility-specific.

When a proposal leads with a tax product or a guaranteed percentage without interval data and field boundaries, treat it as marketing. EPAct 179D can support a business case where records justify eligibility; it is not a substitute for engineering. Tax filing stays with the CPA.

A clean sponsor packet names the system boundary, the uptime rule (including what counts as an unplanned halt), the ranked options, and the verification method. That is the language PE-led work should survive under capital committee scrutiny.

If you are an owner or CFO reading this: ask operations for the last utility allocation to exhaust/makeup and the last three vendor packages for the same system. That package is enough to start a diagnostic conversation without a multi-week study.
