PRF-DC protocol · draft for pilots

Cooling that saves water, proven.

The cooling water saved is measured and verified by a third party, with energy and carbon recorded alongside.

Cooling water loop of a data centre

02Situation

Data centres depend on the basins where they cool.

Water saved at one site frees resource in its basin.

  • Server roomsHeat to remove, continuously.
  • Towers and loopsWater drawn at every cooling cycle.

03Who gains

Operator or buyer, both count.

Each saving is proven, then recognised by whoever funds it.

  • OperatorsCertified water efficiency at every site.
  • BuyersVerified savings, not declarations.
  • BasinsA local resource that stays available.
  • SuppliersThe value of the saving goes to whoever made it possible.

04Alignment

Credible by construction.

References that auditors, regulators and financers already know.

  • Verification
    • ISO/IEC 17029
    • ISO 14064-3
  • Water method
    • ISO 14046

05What we certify

One measure, three records.

Water, energy and carbon are recorded separately, from one measure.

  1. Water withdrawn per cooling unit.
  2. Energy used by the cooling.
  3. Carbon linked to that energy.
  4. Any trade-off between water and energy is shown.

06How it works

From site to registry.

The baseline is fixed before any works.

  1. 01Measure the baselineRecord the water drawn before any change.
  2. 02ChangeModify the circuit or the cooling mode.
  3. 03CompareCompare the water drawn after the change.
  4. 04VerifyAn independent verifier checks. Veracity calculates, never validates.

07The measurement

Measure the flow, not an average.

Each saving starts from a flow measured on the loop.

  1. Cooling water flow, measured continuously.
  2. Cooling energy, read at the same step.
  3. Baseline fixed before works and validated by the verifier.

08Get started

Cooling water efficiency is open to founding pilots.

Start with one site: a measured baseline, then a change.

+Questions

Is the protocol final?

No. PRF-DC is a draft, ready to be used in pilots.

Why show energy and carbon next to water?

Because a water gain can cost energy. Every trade-off is shown, never hidden.

What is a performance record?

A saving measured against a baseline fixed before works, and verified by a third party.

Is this an offset?

No. It is a measured performance, not a water offset or a CO₂ removal.

Who verifies?

An accredited body, independent of Veracity (ISO/IEC 17029). Veracity's agent calculates and prepares the evidence; it never validates.

Who can contribute?

Data centre operators, industrial sites and buyers of projects in their basins.
