How Tuu Verified works.

Tuu measures operational performance only.

The scored layer is built from monthly raw operational inputs, then converted into rolling annualised KPIs and weighted sub-scores. Policy declarations, narrative claims and self-assessed indicators do not form part of the score.

This is intentional. The aim is to produce a defensible performance record for procurement, owner reporting, lender review, disclosure and audit-related use.

One shared operational dataset.

Tuu Verified operates on one shared operational dataset across Hotels, Events and ISO 20121. The core scoring logic, benchmark treatment and verification method are common across the system. Track-level differences sit in cadence, supporting documents, output context and external framework alignment — not in separate scored architectures.

Five operational areas, organised monthly:

1. 01

   Energy — Purchased electricity, renewable energy and relevant fuels converted to kWh before entry.

2. 02

   Water — Total water use and recycled or reused water.

3. 03

   Waste — Total waste and diverted waste.

4. 04

   Food — Food purchased and food waste.

5. 05

   People — Training hours and full-time equivalent headcount.

Built-up area is the fixed denominator used for area-normalised KPIs unless a controlled update is issued.

Rolling annualised, from month one.

Intensity KPI    = rolling annualised total ÷ built-up area
Share KPI        = rolling annualised subset ÷ rolling annualised parent
Training per FTE = rolling annualised training hours ÷ rolling average FTE

The overall score is the weighted sum of the eight KPI sub-scores. Tuu does not apply policy modifiers, narrative overlays or internal carbon calculations.

Every input traces to evidence.

Integrity rules

• Subset values cannot exceed their parent totals

• Unsupported numeric inputs cannot form part of a verified cycle

• Corrections must be version-flagged and fully traceable

Independent review by HLB.

HLB International acts as the independent verification partner across all Tuu Verified tracks. HLB is a global network of independent accounting and advisory firms.

Their review covers four areas:

Each completed cycle produces a time-stamped Evidence Pack with a unique Record ID and the verified KPI dataset, registered on the Blockmark Registry.

Same KPI backbone. Different cadence.

All tracks use the same scored KPI backbone. They differ in cadence, supporting documents, documentary overlays and external framework alignment.

• Tuu Verified | Hotels

  Biannual · 6-month cycle

  Six-month cycles aligned to owner reporting, lender review and platform onboarding workflows. Reviewed against hospitality benchmarks and GSTC Industry Criteria for operational context.

• Tuu Verified | Events

  Quarterly · 3-month cycle

  Quarterly cycles aligned to tender and procurement timing. Reviewed against the same operational backbone with venue-level scope and supporting evidence.

• Tuu Verified | ISO 20121

  Staged · audit-aligned

  Staged cycles aligned to ISO 20121 audit readiness. Adds a clause-mapped evidence overlay on top of the scored KPI base.

Versioned. Time-stamped. Immutable.
