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) worker-safety 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.
