How it works
Sense. Understand. Act.
Three layers, working as one. The sensing keeps the building honest. The data layer makes it understandable. The agent makes it act.
Sense: the foundation
IoT sensors and your existing meters and systems stream what is really happening in the building: occupancy, air quality, energy use, temperature, and equipment status. Sensing is privacy-first, no cameras required for occupancy, and protocol-flexible, so it works wireless where you need it and wired where you already have it.
This is the trusted foundation. Everything above it is only as good as the signals coming in.
Understand: the data layer
A live 3D digital twin organizes every signal into one coherent model of your building, zone by zone, asset by asset. It is how Arva knows not just what changed, but where, why, and what it affects.
The twin is the map; it is not the destination. Its job is to make the building legible so that intelligent action is possible.
Act: the agent
Arva, DigiNest's autonomous AI agent, reasons over the model and takes action: optimizing low-risk decisions automatically and bringing high-impact decisions to you with a recommendation, the reasoning, and the expected outcome already prepared.
You set the boundary between automatic and approval. The building does more of its own work; your team does more of theirs.
Meet Arva →Autonomy earns its place.
Many tools start with the dashboard and stop there. DigiNest is built the other way around: sensing earns trust in the data, the data layer earns understanding, and only then does the agent act.
That sequence is what makes autonomy safe. Arva acts on a verified picture of the building, within limits you control, with every action logged.
Frequently asked.
What is the difference between the digital twin and Arva?
The digital twin is the live data layer that organizes the building's signals into one understandable model. Arva is the AI agent that reasons over that model and takes action. The twin enables; Arva acts.
Do I need new sensors to get started?
Not necessarily. DigiNest can begin with your existing meters and systems, and add sensors where richer signals would help.
How does DigiNest keep autonomous action safe?
Arva acts on a verified live model, only within the operational limits you grant, with human escalation for anything outside its scope and a full audit trail for every action.
