Building intelligence for organizations
Building intelligence that stays with the building.
Harmelo turns fragmented building history into operating intelligence: what you own, what is known about it, what changed and what needs attention or funding next, kept useful for every party who touches the building.

- Know itBuildings, equipment and every signed visit, in one record.
- Operate itWhat needs attention or funding, with its reason, and what was done.
- Preserve itHistory that outlasts staff, contractors and subscriptions.
- Pass it onThe record moves to the next owner or operator, with its provenance.
The problem
Buildings keep losing what they already learned.
An organization pays for an inspection, a reserve study, an engineering assessment and years of service visits. Then the consultant hands in a report, the contract changes and the person who knew the building leaves. The next decision starts from a search through inboxes, spreadsheets and memory, and the next professional is paid to rediscover it.
- Every reserve study rebuilds the equipment inventory that the last one already compiled.
- Service history stays with the vendor, not with the equipment, and leaves when the contract does.
- Capital plans are rebuilt from memory every budget cycle, without the documented install dates and costs.
- Handovers lose the warranties, manuals and open recommendations that the building already paid for.

The operating model
One continuing record that becomes more useful every time work happens.
The record is the foundation, not the whole product. Each visit, document and assessment makes the record more complete, and a more complete record answers more of the questions an organization has to decide on.
- RecordWork is captured at the equipment, signed by who did it.
- ContinuityThe history stays with the building through every change.
- IntelligenceThe record shows what needs attention, funding or evidence.
- ActionFollow-ups, plans, handovers and reports start from it.
- OutcomeWhat was done and what happened next are recorded too.
Not another work-order system. A CMMS schedules work, a property system tracks leases and a service CRM bills the visit. Harmelo keeps what each of them loses: the governed history of the building and its equipment across every contractor, system and owner, and the intelligence that history makes possible. It runs alongside the systems you already use.
Every job adds to what the building knows.
One record per building: what is installed, what is documented, what work was done and by whom, the evidence behind it, and what is still unknown. Every visit leaves the next one better informed.
Missing information is shown as missing and is never treated as a defect. The record does not diagnose equipment, predict failure or replace a qualified professional's judgment.
7 of 7 entries on the record
- InstalledModel, serial and installation details recorded when the unit goes in.
- Documentation attachedInvoice, manual, warranty papers and photos kept with the unit.
- Service visit recordedChecklist, readings and photos filed by the technician who did the work.
- Observation addedA finding noted at the equipment, with its evidence beside it.
- Follow-up completedThe recommendation and what was decided, recorded against the same unit.
- Equipment replacedThe new unit starts its own record. The old unit's history stays with the building.
- History preservedStaff, contractors or owners change. The record stays with the building.
Continuity
The software can change. The building history stays.
Staff leave. Contractors change. Properties sell. Subscriptions end. Harmelo keeps the record attached to the building and its equipment, so the next person starts from what is already known instead of rebuilding it from scratch.
- Owner ACommissions the building and its records
- Operator AInstalls, services and documents for years
- Contractor AFiles every visit at the equipment
- Operator BTakes over with the history, not a blank screen
- Contractor BStarts from the last visit, not from rediscovery
- Owner BBuys the building and its memory
When a staff member leaves
The record belongs to the organization, not to a person. Their visits, notes and decisions stay on the building with who recorded them, and their access ends when you remove it.
Otherwise lost: what one person knew about the building.
When the contractor changes
A new contractor you authorize works from the equipment, its service history and its open recommendations. Contractor access is yours to grant and to end; it never carries over on its own.
Otherwise lost: the service history that left with the last vendor.
When the operator or manager changes
A new operator inherits the equipment, service history, documents, evidence, warranties, permits, capital projects and the documented costs behind them. The record carries its provenance with it.
Otherwise lost: years of history rebuilt from inboxes and memory.
When the property sells
The building's record moves to the receiving organization by an authorized custody transfer: proposed, accepted and audited on both sides, with a manifest of what moves and what stays.
Otherwise lost: the warranties, manuals and open items the building already paid for.

Sell the building without deleting its memory.
- What transfers. Building identity, equipment records, service history, evidence, warranties, permits and inspections on record, capital projects, replacement history, handover documents, and the provenance and audit history.
- What stays. Private and internal working notes, another party's confidential material, contractor access, and the outgoing organization's own portfolio planning.
- How it happens. The outgoing organization proposes, the receiving organization accepts and carries it out, and the outgoing organization's access ends. Every step is recorded in Audit.
Your building should not forget because your subscription changed.
When an organization's paid service ends, its account becomes read-only. It is not deleted and it is not locked away. Reactivating returns the same record.

Read-only access applies to Harmelo organization accounts. Closing an account entirely is different: the Terms of Use and Privacy Policy describe what happens to its data then.
Continuity, not uncontrolled sharing. Records remain governed, access is permissioned, transfers are authorized, provenance stays intact, and private information does not follow the building where it should not.
What Harmelo helps you know
Seven questions every building owner is asked, answered from the record.
Real product workflows
The real workspace, solving real problems.
Current screens from Harmelo, opened in a fictional demonstration organization. Each one starts from a problem organizations already pay for.
Capital planning
- The problem
- Every reserve study rebuilds the equipment inventory from scratch.
- What Harmelo does
- Installation dates, service history, engineering evidence and documented costs stay with each asset, and the reserve planner compares lower, base and higher scenarios.
- The outcome
- The next plan starts from what is already known, for review with the professionals who prepare it.
Equipment history
- The problem
- When a contractor changes, the service history leaves with them.
- What Harmelo does
- Every signed visit is filed against the unit it was done to, by the company and technician who did it.
- The outcome
- The next contractor starts where the last one finished, instead of diagnosing from scratch.
Field to office
- The problem
- Field notes arrive incomplete and are retyped in the office.
- What Harmelo does
- The technician records readings, photos, findings and required sign-offs at the equipment; the office sees what each record still needs.
- The outcome
- Information is captured once and is ready for the owner, the office and the next technician.
What needs attention

- The problem
- Open recommendations and missing documents sit in reports nobody reopens.
- What Harmelo does
- Each building shows what is open, what is missing and what changed, every item with its reason and source.
- The outcome
- Attention goes to what is documented as open, before it becomes an emergency or an unfunded surprise.
Evidence outputs

- The problem
- Insurers, lenders and buyers ask for maintenance evidence that takes weeks to assemble.
- What Harmelo does
- Evidence packs and the Infrastructure Disclosure Report state each fact with its class and source, and say what is not on record.
- The outcome
- The reader gets facts with sources, prepared in minutes from the record already kept.
Intelligence
Every building you are responsible for, on one screen
The record is read four ways. Each item carries its reason and the evidence behind it. Where there is not enough evidence, the record says so, rather than having gaps guessed at or quietly averaged in.
Estimates should be reviewed alongside current inspections, professional advice and the organization's own planning requirements. An estimated replacement window is a planning assumption, not a prediction of failure.

Where Harmelo fits
Everyone contributes. Everyone benefits. The history stays with the property.
Access follows role and permission. What an account can open is set by the organization that holds the record, not by the page. See all nine roles
Owner or operator
- The problem
- Every reserve study, acquisition and budget cycle pays to rediscover the same buildings.
- What changes
- One record per building, with open items, gaps and capital planning across the portfolio. The owner decides who may add to it.
- Gets
- Decisions that start from what is known, continuity through turnover, and an Infrastructure Disclosure Report when a building changes hands.
Contractor
- The problem
- Technicians arrive without history, and good work is lost between visits.
- What changes
- Before the visit, the history; in the field, one consistent record; after it, office completion and a customer summary; over time, service intelligence from your own records.
- Gets
- Faster first visits, work that stays credited to the company, and a record customers value.
Housing provider
- The problem
- Between assessments, the history of each building lives in inboxes and memory.
- What changes
- Continuity across buildings, units, systems, contractors and staff.
- Gets
- Documented history for capital planning and future reserve or depreciation work.
Builder
- The problem
- Model, warranty and trade information is lost between construction and the first service call.
- What changes
- The record follows the home from construction through possession, warranty and service into ownership.
- Gets
- Fewer callbacks that start with a search, and a handover the buyer and the next service provider can use.
Inspector
- The problem
- A report is read once and filed.
- What changes
- Inspectors and consultants contribute findings with identity and date attached, with observed, not observed and outside scope kept clear.
- Gets
- Work that stays useful after the inspection date and after the engagement ends.
Technology partner
- The problem
- Device data sits in a dashboard, apart from the equipment history.
- What changes
- Readings and events sit beside what is installed and what was serviced.
- Gets
- Context for its data while keeping its own customer relationship.
Why you can trust the record
Built by people who have done the work, governed like evidence.
Harmelo was started by a heating and cooling contractor who spent years in the mechanical rooms of homes and buildings, watching the same history get lost. It is built to the standard an owner, a lender or an auditor would hold it to.
- Every fact has a class and a source: documented, technician observation, entered, engineering assessment, planning assumption or not documented.
- A person decides what changes the record: candidate facts wait in evidence review until someone accepts or rejects them.
- Every action is in the audit history: who filed, reviewed, shared or prepared what, and when.
- Your information stays yours: the organization holding the record decides who reads and writes it.

A record everyone can work from. Harmelo keeps service history connected to the building, so owners, contractors, tradespeople and portfolio teams can understand what happened, what changed and what needs attention next.
- Facts, not rankings. Harmelo preserves documented work. It does not rank contractors or sell preferred placement.
- Work that stays connected. Service notes and history remain attached to the equipment, creating continuity across visits, contractors and ownership changes.
- Clear boundaries. Harmelo does not certify work quality or promise leads. Participation does not give Harmelo ownership of a stakeholder's underlying information.
Why now
The people who remember the buildings are leaving, and the questions are getting harder.
Experience is retiring
Facility staff and long-serving contractors carry most building history in their heads. When they leave, it leaves with them unless it is on a record.
Equipment is reaching replacement together
Boards, funders and reserve requirements ask for a documented basis for capital plans, not a list rebuilt from memory.
Insurers, lenders and programmes ask for proof
Renewals, financing, acquisitions and energy programmes increasingly ask what is installed and how it was maintained. A kept record answers in minutes.
