Why it matters on the job

Running cost up front

Annual energy and cost so the cheap pump that costs more to run gets caught.

Payback you can defend

VSD and efficiency upgrades with real payback periods, not vibes.

Lifecycle, not sticker

Capital + energy + maintenance over the asset life — the number that matters.
