Every service company keeps its own notes in its own format. The system's real history scatters across trucks, binders, and software that gets replaced — so owners, operators, and regulators never see what's actually happening. Harmelo gives every mechanical and energy system one standardized, signed, persistent record that stays with it for life. From homes to portfolios to public infrastructure, one registry, one identity per asset, one history that doesn't reset.
A city sees its public infrastructure. A portfolio operator sees its buildings. A contractor sees their work. Every view is the same registry — one standardized record, permissioned to the stakeholder who needs it. The tech below isn't the product. The registry underneath it is.
In 2008, a chiller was installed at a 400-unit apartment building in Brooklyn. Today it's on its fourth owner, sixth contractor, and third control system. Ask the super what broke last winter and he'll tell you. Ask what's going to break next winter and nobody can.
Every building has this story. The records existed — they just lived in binders, in legacy software, in the memories of people who no longer work there. Every ownership change, every contractor rotation, every platform migration scattered them. What little continuity survived was fragmented, unstandardized, and unverifiable.
CRMs track relationships. CMMS track work orders. Both are owner-centric — they reset the moment the owner changes. A registry is asset-centric. The record belongs to the mechanical or energy system itself. It survives every transition. Every entry is standardized. And across millions of systems, the data compounds into intelligence no siloed tool can produce.
One record. Many views. Continuous history. Neutral ground. That's what ends the story above.
Harmelo Corp. operates the persistent identity infrastructure for mechanical and energy systems. Two reports come out of it, structured for the buyers who need them: Asset History Report (AHR) for homes, builders, contractors, property managers, and multifamily owner-operators. Infrastructure Disclosure Report (IDR) for institutional portfolios and public infrastructure.
The record that follows the property. AHR captures every install, service event, permit, warranty, and inspection across a building's mechanical and energy systems — signed by the contractor who did the work, owned by the property owner, transferable to whoever owns the property next.
The institutional artifact for diversified portfolios and public infrastructure. IDR delivers regulatory-grade, transaction-ready, audit-defensible records across heterogeneous holdings — the kind of disclosure document a portfolio operator hands a lender, an investor, a regulator, or a buyer.
Both reports are built on the same infrastructure: every asset gets a permanent identifier (HMIN for mechanical and electrical, HEIN for energy and generation), every service event is signed by a credentialed contractor, every record is standardized to the same schema. The registry is the source of truth. AHR and IDR are how that truth gets delivered to the people who need it.
Every registry needs a unit of identity. HMIN™ and HEIN™ are the primitives that make every mechanical and energy system on earth uniquely addressable — so service data written by one contractor reads the same as service data written by any other, across any building, any jurisdiction, any owner. Standardization is what turns raw entries into compounding intelligence.
Permanent identity for HVAC, mechanical, plumbing, and building systems. Assigned at registration. Every service event — by every licensed trade, across every ownership change — writes back to the same record, in the same format, for the life of the asset.
Permanent identity for energy infrastructure — solar arrays, battery storage, meters, generation assets, and distribution systems. Durable across ownership changes, operator transitions, and regulatory reporting cycles.
A neutral Infrastructure Identity Intelligence Registry™ sits above every operator, contractor, and platform. Lenders, insurers, governments, and institutional owners read the same standardized record — each through their own permissioned view. No silos. No resets at transitions. No one side owns the data; every side gets the intelligence. The record itself is written in the field and carried to homeowners through the Asset History Report.
Last three service visits. Isolation points. Compliance status. Shutoff location for first responders — before the laptop is open. Now multiply that across every regulated system in the jurisdiction. Cross-department compliance becomes visible. Public-housing accountability becomes real. Capital planning across the public portfolio stops being guesswork grounded in inspection-cycle snapshots and starts being grounded in continuous lifecycle data.
Which systems are aging. Which contractors actually perform. Where capital is truly needed. Forecasting across the portfolio grounded in standardized, continuous data — not spreadsheet theater. Disclosure packages assemble in minutes instead of weeks, and transactions and refinancings move faster because what's owned is already documented. Explore Harmelo for portfolios →
The mechanical and energy systems inside the asset have always been a blind spot at origination. The registry turns them into verified, underwriting-grade data — condition known, not assumed. Loans price against actual condition, and refinance and disposition move faster because what sits behind the loan is already documented and defensible.
Property risk has always been priced largely blind to what's inside the building. The registry makes mechanical and energy condition structured and verifiable. Claims resolve against signed records, loss exposure becomes visible before it becomes a claim, and an opaque asset class becomes the first underwriting-grade mechanical dataset.
Every HVAC unit, chiller, generator, and energy system keeping the venue running carries a signed, timestamped service history. Safety and compliance claims reference the specific inspection entry that backs them. When sponsors, regulators, or auditors ask for proof, the answer is a record — not a narrative.
Standardized service records reveal how units fail, why, and where — drawn from what the trades actually write, not telemetry. No sensor, no firmware, no connection to the unit, so warranties stay intact. Problems surface as patterns instead of recalls, and suppliers can stock ahead of a shortage instead of scrambling after one.
Homeowners, home builders, the contractors who service the equipment, and the property managers who coordinate it all work through the Asset History Report — the homeowner-facing face of the same registry. That's where each record is created, signed, and carried from one owner to the next. See the Asset History Report →
Harmelo builds and operates one thing: the Infrastructure Identity Intelligence Registry. AHR and IDR are the two reports the world transacts on — but they're outputs of the registry, not the engine. The longer it runs, the more it produces. A CRM can't do this. A CMMS can't. It takes infrastructure built for continuity, not transactions.
The neutral, permanent, append-only registry that sits above every owner, operator, contractor, and platform. One standardized identity and one continuous history per asset — portable, independent, owned by no single side. This is the company. Everything below is something the registry produces.
The full continuous record for any registered system — install, every service event, upgrades, warranty, condition, remaining life. Travels with the asset across every ownership change. Learn more →
Transaction-ready, underwriting-grade disclosure assembled directly from the registry. Sale, refinance, insurance renewal, operator transition — the document is already there, verified, and defensible. See a sample IDR →
Pattern recognition across the registry — what performs, what extends life, what doesn't. Forecasting grounded in continuous, standardized data.
Replacement and multi-year capital forecasting for owners and institutions — grounded in the registry instead of spreadsheets.
One standardized condition score for any asset or portfolio that reads the same to an owner, a lender, and an underwriter.
Authenticated, signed entries from every licensed trade — keeping warranties valid and every record defensible across ownership changes.
Telemetry platforms, monitoring services, connected-equipment OEMs, and energy systems already generate the data institutions want on the record. Integration partners connect that data to the registry — so a reading written by one system becomes part of the same permanent, standardized history every owner, lender, and insurer reads. The systems behind the biggest preventable losses, water and fire, matter most of all.
Connect once and your telemetry, monitoring, or OEM data sits on the record as its institutional reach grows — a durable identity for what your systems produce, and a path to the people who act on it.
Water detection & surveillance, fire detection & suppression, telemetry & remote monitoring, building automation, energy & solar, battery storage, IoT, and connected-equipment OEMs.
Lenders, insurers, governments, and institutional owners price, regulate, and underwrite the built world on mechanical and energy data that has never existed in a standardized, verifiable form. Harmelo builds the neutral registry that creates it — owned by no single side, permanent by design, and more valuable with every record written. The reports are how the world transacts on it today. The registry is the asset.
The Asset History Report is how the registry surfaces in the real world. For every enrolled asset — a furnace, a chiller, a generator — the AHR is the verified, portable record of what's installed, what's been serviced, and what's coming next. It travels with the asset across owners, contractors, and decades.
AHR is a live Harmelo product, available now at assethistoryreport.com. The other registry modules — IIIR, IDR, ICI, IFI, POI, and WarrantyTech — follow the same pattern: built on the persistent identity layer, surfaced through purpose-built interfaces.
