Cut service cost and risk with decisions that stand up to audit.
Aeterno turns your building and home energy data into governed, evidence‑backed decisions—so you resolve issues faster, prove compliance instantly, and unlock new revenue from every asset.
Why a Model Asset Platform
A Model Asset is a governed digital representation of a specific home, building or system that carries models, data, policy and evidence—so you can generate value across the entire lifecycle, not just at anomaly detection time.
Grow revenue from your installed base
More qualified pipelines, higher conversion to upgrades and new services, and better flex participation—grounded in per‑asset evidence.
Cut service and warranty cost
Fewer truck rolls and callbacks, faster triage and approvals, and clearer prioritisation for EMCs and field teams.
Reduce risk while automating more
Assist‑by‑default governance, promotion to Auto via measurable gates, and audit‑ready evidence for regulators, customers and boards.

Leaders in asset‑heavy businesses tell us the same story: decisions are slow, risky to automate, and hard to defend to regulators and boards.
- Decisions need to move faster — Asset portfolios keep growing, but expert capacity doesn't. What worked at 100 sites breaks at 1,000. Value gets trapped in review queues while field teams, contact centres and partners wait.
- Evidence expectations are rising — Boards, regulators, and customers expect transparent rationale and proof. Manual reconstruction of decision trails takes weeks when everyone needs answers in hours.
- Coordination costs are climbing — Operations, finance, compliance, and partners each hold part of the truth. Reconciling viewpoints across tools consumes time that should go to outcomes.
- Change velocity keeps accelerating — New products, tariffs and regulations arrive monthly. Process improvements that take quarters leave value on the table.
The result is slower growth, higher service cost, and weak confidence to automate—even when the data exists to do better.
How Aeterno solves this
We turn your models, data and policies into decisions that travel with your assets—so every stakeholder sees what to do next, and why:
- ●One truth, many viewpoints — A single governed kernel generates role‑specific views. Operations sees maintenance priorities, finance sees investment cases, compliance sees audit trails—all from the same evidence base, without reconciliation wars.
- ●Scale expertise, not headcount — Your domain knowledge becomes reusable Model Assets. What took expert hours becomes instant recommendations with full evidence—so you cut backlog, reduce cost‑to‑serve, and free experts to improve the system, not work in it.
- ●Evidence travels with decisions — Every recommendation ships with its proof: data sources, model logic, policy references, confidence levels. You stay audit‑ready from day one, not scrambling to assemble evidence months later.
- ●Automation you control — Start in Assist mode with human oversight. Promote to Auto only when you've proven the business case. Set your own gates, change windows and approval chains—so automation reduces risk instead of introducing it.
