Living Wallet

The problem

The purchase process ends at handover. Financial reality only starts there. Many promise the same; few can evidence that they deliver it.

A home passes through design, build, sales, financing, handover, operation and resale. Between brochure, handover and real operation there is no shared, reliable layer of information. The developer sells design, specification and brochure claims long before performance can be measured. The buyer decides on a promise. The lender assesses affordability without the running costs that follow.

Real value of living

It is not just square metres. What matters is the real value owners and occupiers receive. The Living Wallet links living quality to the total monthly cost: in the illustrative example a total of €2,380 per month made up of €1,850 mortgage, €140 energy, €310 operating costs and €80 maintenance.

Against that total sit indoor comfort, indoor quality and summer and winter comfort; energy and CO₂ consumption, cost and future readiness; digital and smart living through connectivity, usability and operational readiness; and accessibility and safety. The outcome is evidenced quality that carries into resale and financing.

Product architecture

One shared evidence base, a different view for every decision. Project documents, energy and MEP information, contracts and approvals, operating costs and operating data feed a single Living Wallet.

From it come the Living Performance Index for quality and future readiness, the Total Cost of Living covering financing plus running costs, the Living Wallet Passport showing status, evidence and open items, and the Performance Record of actual operating performance. Each role sees what it needs: the buyer asks what they get and what it costs, the lender how robust overall affordability is, the developer which product strengths are provable, and operations how the building actually performs.

Lifecycle loop

The Wallet grows with the building, and forecasts become verified performance: promised, designed, built, sold and financed, handed over, measured, verified. Design produces a Design Score, build produces evidence and variations, sales produces the Buyer View, financing the Total Cost of Living, handover a Readiness Score, operation a verified LPI and resale a Performance Record. One database follows the same property across the entire lifecycle, and a verified LPI improves the next design.

Living Performance Index

Quality becomes measurable, but only if data coverage and evidence confidence hold. Eight categories of 12.5 points each make 100: design and construction quality, energy and CO₂, indoor comfort, operating cost and affordability, digital and smart living, accessibility and safety, location and mobility, and resilience and future readiness.

Three layers govern statement quality: the Design Score asks how strong the intended quality is, data coverage asks which expected evidence is available, and evidence confidence asks how reliable the statements are. A category gate means no reliable evidence, no category score. A project gate marks a scheme below minimum coverage as not yet assessable.

Each category has fixed test criteria with a fixed point key. Testing is rule-based against the value evidenced in the document, not by a language model. Without evidence a criterion stays unrated and is not counted as zero.

From evidence to communication

Evidence confidence drives not only the score, but what sales can promise with proof. Seven evidence levels run from a claim with no supporting evidence, through design, calculated, contractually documented, independently checked, installed and tested, to confirmed by real data in operation.

A traffic-light logic then controls technical claims. A projected final energy demand of 43.7 kWh per m² per year, sourced from the energy concept and calculated rather than measured, is amber: usable only with the qualifier projected. A fibre connection and digital resident portal that are contractually documented in the technical building specification are green: approved and usable without restriction. Insufficiently evidenced claims are red and not approved for use.

Developer view

Technical documents, cost assumptions and reports sit apart, so product strength stays hard to compare in sales. The Living Wallet turns quality promises into documented, approved statements: strengths become visible and comparable through the LPI, every sales wording is linked to source and evidence level, missing evidence and design gaps surface before marketing starts, and design is checked at commissioning and verified in operation. The LPI also positions a project against schemes of similar use, size and region, and the comparison base grows with every project assessed.

Commercial value from the developer perspective

An illustrative model of 100 units, €50m GDV and 50% average development finance drawn, so €25m: a price premium of 2 to 3% is approximately €1.0 to 1.5m, three months faster sales absorption brings earlier capital recovery, and lower interim finance cost is approximately €375k, calculated as €25m at 6% per year over three months.

The illustrative earnings contribution is €1.4 to 1.9m, roughly 2.8 to 3.8% of GDV, before operational effects. This is a full-scale reference case, not pilot size. The price premium and faster absorption are hypotheses to be validated per project with pilot data, operational effects are not included, and the model carries no commitment to an achievable uplift.

Value from the buyer and investor perspective

The Wallet makes living performance, total cost and evidence clear at a glance. An illustrative unit view shows an LPI score of 62 out of 100 with a potential of 73, a total cost of €2,380 per month, category scores for energy and CO₂, comfort, operating costs and digital, evidence confidence of 3 out of 7, data coverage of 68% and three open items.

The buyer gains more certainty before buying because quality features are linked to source and evidence level, a better affordability decision because financing, energy and operating costs become visible together, less document hunting because specification, energy, reports, sign-offs and contracts sit in one Wallet, and continuing value after handover as forecasts are replaced by real performance.

Value from the lender perspective

An added view on quality, cost and evidence that complements credit review and valuation and replaces neither the credit decision nor due diligence. In the illustrative case, financing of €1,850 per month plus running costs of €530 gives a total cost of €2,380 per month, alongside data coverage of 68%, an LPI Design Score of 62 with a potential of 73, and three open items with cost impact.

This matters because project-level energy and operating costs complement the individual loan instalment, sources, forecasts, evidence levels and open items are stated explicitly, open items with possible cost or completion impact become visible, and after handover design can be reconciled with real operating and consumption data. The aim is better transparency, not an automated credit decision.

From intelligence to verified performance

The Wallet does not stop at documents and scores; it reaches actual operating performance in one continuous, measurable logic. Design gives the LPI Design Score of what was designed and calculated, commissioning gives the Readiness Score of what was actually installed and tested, and operation gives the verified LPI of how the property actually performs.

Five capabilities sit behind it: intelligence through document analysis, the LPI and Cost View and AI gap detection; hardware through IoT sensors, smart metering and gateways; integration through BMS and BACnet and open interfaces; execution through commissioning, optimisation measures and local partners; and verification through monitoring, MRV and the verified LPI. workcloud24 closes the gap between the designed building, the installed systems and actual operation.

Starting with a pilot project

You provide the documents, we do the rest. A suitable pilot is a new build sold unit by unit, anywhere from concept design to active sales, with a manageable volume of documents and ideally up to approximately 3,000 m². We need the project name and location, the number of units, the current project stage, access to existing documents and one point of contact.

The first output is the LPI Design Score, data coverage and evidence confidence, a gap report and measures, the Living Wallet and Passport, the Total Cost of Living view and buyer and lender information. There is no complex technical questionnaire, no new data room structure, no manual data entry, no pre-sorting of documents, and no system integration or sensors at the start.
