How Tuu Verified works.

All scored data enters the system as monthly raw operational inputs.

From that point, Tuu applies a rolling annualised calculation method from the first month onward. The system does not wait for a full twelve months before producing a comparable result. Instead, it annualises available monthly history until a full rolling year is established.

The purpose is to reduce seasonality distortion, limit timing manipulation and produce more stable performance curves over time.

Every monthly numeric input that feeds a scored KPI must be traceable to a primary source record or controlled aggregate. Typical examples include utility bills, invoices, meter logs, haulier or weighbridge records, training logs, payroll records and other operational source documents relevant to the reporting period.

Supporting documents also matter, but they do a different job. They help define scope, support framework mapping and assist documentary review. They do not change KPI calculations.

When an operator uploads a source document, the Tuu Performance Hub reads it and populates the relevant entry — the figure, the period and the source it came from — for the operator to approve. Every figure is confirmed by a person before it enters a verified cycle, and HLB reviews against the same source document. Automated reading speeds the trace. It does not replace it.

Source-document reading uses Microsoft Azure Document Intelligence, the same extraction service used in regulated finance and insurance workflows. It reads what the document shows, with the source visible — it does not generate or predict values.

All KPI definitions, formulas, benchmark corridors, weights and validation rules are version-controlled. When methodology changes, a new framework version is created. Historical scores are not retroactively altered.

Each verification cycle produces an immutable, time-stamped dataset and Record ID, preserving continuity for audit, procurement, lender review and longitudinal analysis.

The Tuu Verified Smart Trust Mark is issued to a named property for a stated period. It stays valid only while the property keeps its verification current.

Tuu suspends the mark if a property stops submitting its monthly data and evidence, if a quarterly review cannot be completed, or if the independent review finds exceptions that the property does not resolve. Tuu withdraws the mark if data or evidence is found to be misrepresented, or if the property no longer meets the scheme's requirements.

Tuu tells the property why, and where an issue can be corrected, gives it the chance to correct it before the mark is suspended.

Every suspension or withdrawal is recorded on the BlockMark Registry, and the property's public status updates immediately. While suspended, a property may not display the mark or make claims based on it. The mark is reinstated only after a completed review.

The Tuu Performance Hub also shows each property two estimates: its carbon and its costs. They are not part of the Tuu Rating, are not reviewed by HLB and are not in the Evidence Pack. They are labelled as estimates wherever they appear. They add context to a property's Tuu Verified data and Evidence Pack; they do not replace them.

Carbon is the energy a property reports each month (purchased electricity and fuels, in kWh) multiplied by an emission factor for each source: the country's grid factor for electricity, which is location based, and IPCC 2006 factors for fuels. Renewable electricity is not deducted, because it is part of the energy already reported. The estimate is refined when the property adds its occupied room nights. It is shown as a Proof Provided Estimate when its electricity and room nights match the bill and occupancy report the property attached. That is supporting data, not verification.

Costs are what each month cost. Tuu uses the property's own bill amounts where it has added them, and its usage at standard rates for its country where it has not. Food wasted is priced from the property's own food spend per kilogram, and waste collection from its own bill. Each cost is compared with what similar properties of the same type spend for the same size: per occupied room night when enough of them report room nights, otherwise per square metre of built-up area. The comparison needs at least three similar properties and only ever uses their middle figure, never another property's own.

Standard rates are published business prices for each country in Southeast Asia and Hong Kong, for example electricity tariffs from Thailand's Energy Regulatory Commission, Vietnam's EVN, Malaysia's TNB, Indonesia's PLN, the Philippines' Meralco, Singapore's SP Group and Hong Kong's CLP Power. Tuu uses them to start with, but a property's actual bill amounts always replace them.

Grid factors for electricity are the latest national figure each country's own agency publishes, such as Thailand's Greenhouse Gas Management Organization (0.4750 kg CO2e per kWh), Vietnam's Ministry of Agriculture and Environment, Malaysia's Energy Commission, Indonesia's Ministry of Energy and Mineral Resources, the Philippines' Department of Energy and Singapore's Energy Market Authority. Where a country has no published figure, Tuu uses the International Energy Agency's world average.

Renewable electricity is valued at what the property pays per kWh for electricity: its bill amount divided by its kWh, or the standard rate until it adds a bill amount. Where the renewable electricity comes from the property's own panels, that is roughly what it saved. Where it comes through a green tariff, it is already part of the bill, so the figure is a guide rather than money saved.

Bill amounts and occupied room nights are optional. Leaving them out never affects a property's Tuu Rating.
