Now with Arva the autonomous building agent
DigiNest is the
AI platform that
makes your building act.
Not another dashboard. An AI building management layer that connects to your existing BMS over BACnet & Modbus, senses everything that matters, and takes action within limits you set.
- Works with your BMS
- No rip-and-replace
- BRSR-ready
Most building software is built around dashboards.We build around agents.
A dashboard shows you a problem and waits. An agent closes the loop it senses, decides, acts and learns continuously, so routine optimization happens without anyone watching a screen.
Connects to your BMS, meters and sensors 200+ live signals across every zone and asset.
Builds a live model of how each zone behaves, then weighs comfort, cost and carbon together.
Adjusts setpoints, ventilation, lighting and loads automatically within the limits you set.
Adapts to your building's unique patterns and gets smarter with every decision made.
Every other system tells you
something is wrong.
Arva does something about it.
Arva is DigiNest's first AI agent, always-on, acting within limits you set. Low-risk optimizations happen automatically. High-impact decisions come to you with a recommendation ready to approve.
Arva acts within limits you set. Your approval, one tap.
- Watches 200+ building signals continuously
- Generates energy-saving schedules with impact estimates
- Raises facility tickets before equipment fails
- Drafts BRSR section narratives from your data
- Learns your preferences over time

Buildings represent ~30% of global final energy consumption and ~26% of energy-related emissions (IEA). The opportunity for AI agents to close that gap is enormous. Here is what DigiNest's customers see:
On healthier air: In a controlled Harvard T.H. Chan study, cognitive scores were 61% higher on a green-building day and 101% higher with enhanced ventilation vs. a conventional building (Allen et al., Environmental Health Perspectives 124:805-812, 2016; DOI 10.1289/ehp.1510037). Healthier air shows up in how people think and work.
Who DigiNest
is built for.
Real operating-cost reductions and ESG proof that protects asset value, supports green financing, and satisfies board-level reporting.
Stop firefighting. Arva handles the routine, prioritizes the alarms that matter, and hands you a prepared work order.
Works with the systems
you already use.
DigiNest speaks the open protocols your building runs on and connects natively to the BMS and controllers already in your plant room. No rip-and-replace upgrades required.
Frequently asked.
What is DigiNest?
DigiNest is a startup building AI agents for smart buildings. Our first agent, Arva, connects a building's sensors, meters, and existing systems into one live model, then optimizes energy, sustainability, and occupant comfort, automatically for low-risk actions and with your approval for high-impact ones.
What does Arva do?
Arva is DigiNest's first AI agent. It continuously senses the building, understands how each zone and asset behaves, and takes action, adjusting setpoints, ventilation, lighting, and loads within limits you set, and recommending larger changes for human approval.
What is a building energy management system (BEMS)?
A building energy management system (BEMS) is software that monitors, controls, and optimizes a building's energy use across HVAC, lighting, and electrical systems. DigiNest's Arva goes beyond a traditional BEMS by acting as an autonomous AI agent: not just monitoring but continuously optimizing in real time over BACnet and Modbus, without replacing your existing systems.
Does AI HVAC optimization work without replacing existing hardware?
Yes. DigiNest connects over open protocols (BACnet, Modbus, KNX, LoRaWAN) to the systems already installed in your building. There is no rip-and-replace and no new hardware required. Arva operates as a software layer on top of what you already have.
Does DigiNest replace my building management system (BMS)?
No. DigiNest works on top of your existing BMS and devices over open protocols such as BACnet, Modbus, KNX, and LoRaWAN. There is no rip-and-replace.
How does DigiNest help with ESG and sustainability reporting?
It turns the energy and carbon data your building already produces into audit-ready evidence, mapped to frameworks including GRESB, BRSR, CSRD, and ENERGY STAR, continuously, rather than reconstructed before a deadline.
Is occupancy sensing privacy-preserving?
DigiNest uses privacy-first occupancy sensing that does not require cameras. Sensing measures presence and utilization without identifying individuals.
What happens if BACnet connectivity is lost?
Arva monitors protocol connectivity continuously. If a BACnet or Modbus connection drops, Arva flags the gap, holds the last known safe setpoints on affected devices, and alerts your team. No optimization runs against stale data; the system degrades gracefully and recovers automatically when connectivity is restored.
