Cities, portfolio operators, stadiums, arenas, and the contractors keeping them running all transact on records that don't survive a single ownership change. Harmelo gives every mechanical and energy system on earth a permanent, verifiable identity — so compliance becomes auditable, emissions become reportable, safety becomes provable, and capital planning becomes data-grounded.
The registry isn't a diagram — it's a working environment. Cities and portfolio operators see one view. Contractors and trades see another. Every building is a digital twin of itself. Every stakeholder gets exactly the surface they need to act. Pick a seat below.
A chiller installed in 2008 has had four owners, six contractors, and three control upgrades. Ask anyone managing that building today what its full history looks like. They can't tell you — not because the data never existed, but because there was never a permanent home for it.
Records live in contractor binders, legacy software, and the memories of people who no longer work there. Every ownership change, every new service provider, every system upgrade scatters what little continuity existed.
The result isn't just lost paperwork. It's reactive decisions, unpredictable capital spend, and infrastructure that slowly becomes a liability instead of an asset.
HMIN™ and HEIN™ are to buildings what VINs are to vehicles and ISBNs are to books — the foundational identity primitives every other system builds on. Once identity is in place, history compounds.
Persistent identity for HVAC, mechanical, plumbing, and building systems. Established at registration. Follows the system through every service visit, every contractor, every owner — for life.
Persistent identity for energy infrastructure — solar arrays, battery storage, meters, generation assets, and distribution systems. Durable across ownership changes and operational transitions.
Contractors join to prove their work. Owners join to know what they own. Cities deploy Harmelo as a public standard. Insurers and lenders underwrite on verified data. Each side makes the others more valuable.
Cities and public authorities adopt Harmelo as the permanent identity standard for physical infrastructure across their jurisdictions. Every regulated system — boilers, chillers, backflow preventers, fire suppression, EV chargers, energy infrastructure — gets an HMIN™ or HEIN™. Compliance becomes auditable in real time. Capital planning becomes data-grounded. Public infrastructure becomes legible.
Authenticated service logs. Warranty-validating records. Customer retention that survives ownership changes. WarrantyTech™ protects every tech on every job.
Portfolio-wide visibility across every registered system. ICI™ rollups, AHR™ records, IFI™ reserve-fund planning, and IDR™ disclosure output — the rails large-format venues and ESG-committed operators need to report emissions, track safety, and defend capital decisions with verifiable data.
When you sell, your HVAC, water heater, and solar history go with the home — not with you. Buyers see what's been done. You get paid for the work you invested. See how the Asset History Report works →
Infrastructure Disclosure Report™ turns opaque building risk into structured, underwriting-grade data. Insurers price accurately. Lenders lend against assets they can verify.
Every product runs on the same identity layer. Once a system is registered, every module compounds on every other.
The neutral, permanent home for every HMIN™ and HEIN™ record. Append-only. Portable. Independent of any contractor, software platform, or owner.
Full installation, service, upgrade, and lifecycle history for any registered system. A permanent record of every mechanical and energy asset — available to whoever owns it, for as long as it exists. Learn more →
Performance trends over years, not snapshots. Predictive maintenance signals. Replacement timing grounded in actual data, not guesswork.
Replacement forecasting. Multi-year capital planning. Budget smoothing. Reserve fund rails for owners and institutions managing infrastructure at scale.
Underwriting-grade structured data for insurance, sale, refinance, and transaction events. Turns opaque building condition into a defensible document.
Authenticated service logging and trade verification that ensures system-level records remain valid across warranty, ownership, and lifecycle transitions.
Cities, portfolio holders, stadium and arena operators, racetracks with ESG commitments, multi-site operators, and the contractors who keep all of it running. Harmelo is the neutral identity rail every side of the infrastructure economy needs — and nobody has built yet.
