Infrastructure That Remembers. Intelligence That Evolves.
Persistent identity and intelligence for systems that last decades.
Every transition is a reset.
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.
Harmelo was built around one idea: infrastructure history should stay with the system — not the owner, not the contractor, not the platform.
Persistent Infrastructure Identity™
Give your systems an identity they keep forever.
Think about what a street address does for a building. It doesn't belong to any tenant or owner, it belongs to the location itself, and it persists through every transition. Harmelo does the same thing for the systems inside.
Through HMIN™ and HEIN™, every mechanical and energy system receives a durable identifier the moment it's registered. That identity attaches to the system; not the owner, not the contractor and stays through installation, service, ownership changes, and full replacement cycles.
Infrastructure identity is established once. It doesn't reset. It doesn't disappear. It compounds.
HMIN™
Mechanical Identification Number™
Persistent identity for HVAC, mechanical, and building systems. Established once. Follows the system for life — across every service visit, every contractor, every owner.
HEIN™
Energy Identification Number™
Persistent identity for energy infrastructure — meters, generation assets, and distribution systems. Durable across ownership changes and operational transitions.
HMIN™ and HEIN™ are the foundation of everything Harmelo builds. Once identity is in place, lifecycle history can accumulate, intelligence can develop, and capital planning can finally be grounded in something real.
Two identifiers. One continuous record.
A neutral, permanent home for infrastructure intelligence.
The Infrastructure Identity Intelligence Registry™ is where persistent identity becomes lasting intelligence. As systems are installed, serviced, and replaced, every lifecycle event attaches to its HMIN™ or HEIN™. That data doesn't belong to a contractor, a software platform, or a previous owner. It belongs to the system.
Over time, the Registry builds a living intelligence layer across your portfolio — operational patterns, performance history, replacement signals, and financial exposure. All structured. All portable. All compounding.
Lifecycle records that survive ownership transitions and contractor changes
A neutral layer that sits above any single platform or operator
Intelligence that grows stronger the longer a system is registered
Portfolio-level visibility across every system, building, or region
