Data-driven and distributed governance of building facilities management using decentralized autonomous organization, digital twin, and large language models
This paper proposes and evaluates a novel distributed governance framework for smart building facilities management that integrates decentralized autonomous organizations (DAOs), digital twins, large language models (LLMs), and blockchain technology to overcome the limitations of traditional centralized approaches by enabling transparent, secure, and inclusive decision-making.

Imagine a large office building as a giant, complex living organism. Traditionally, keeping this organism healthy (cleaning, heating, cooling, fixing lights) is like having a single, strict head doctor who makes all the decisions without asking the patients (the people working inside) what they need. This paper proposes a radical new way to run the building: a democratic, digital team of doctors that uses a super-smart computer assistant to make decisions together.
Here is how the paper breaks down this new system, using simple analogies:
1. The Problem: The "Dictator" Building
Right now, most buildings are run by a centralized management team. The paper argues this is like a dictatorship where only a few people decide the temperature, lighting, and maintenance schedules.
- The Risk: If the central computer gets hacked (like a cyber-attack), the whole building is vulnerable.
- The Frustration: The people actually living and working in the building often feel ignored. Their needs aren't heard, leading to unhappy occupants and wasted energy.
2. The Solution: A "Digital Town Hall" (DAO)
The authors propose replacing the single boss with a Decentralized Autonomous Organization (DAO).
- The Analogy: Think of this as a digital town hall meeting that never closes. Instead of one manager deciding, everyone with a stake in the building (owners, managers, tenants) gets a vote.
- How it works: They use Blockchain (a digital ledger that acts like a public, unchangeable diary) to record every vote and decision. Once a decision is made by the group, it happens automatically. No one can sneakily change the rules later because the "diary" is locked and transparent.
3. The Eyes: The "Digital Twin"
To make good decisions, the group needs to see what's happening inside the building in real-time.
- The Analogy: Imagine a perfect, 3D video game clone of the actual building. This is the Digital Twin.
- What it does: Real sensors in the building (measuring temperature, humidity, and how many people are in a room) feed data into this digital clone. The "town hall" can look at this clone to see, for example, "Room 302 is empty but the AC is blasting at full power."
4. The Brain: The "Super Assistant" (LLM)
Looking at data is hard. The paper introduces a Large Language Model (LLM) to act as a smart assistant for the group.
- The Analogy: Think of this as a super-intelligent librarian who has read every manual and data log in the building.
- How it helps: Instead of the building manager needing to be a data scientist, they can just ask the assistant in plain English: "Hey, why is the energy bill so high this week?" or "Show me a graph of the temperature in the lobby." The assistant analyzes the data from the Digital Twin and gives a clear answer or suggests a fix, like "Turn off the fans in the empty conference rooms at night."
5. Putting It All Together: The "Full-Stack App"
The researchers built a complete software application (a DApp) that connects all these pieces.
- The Workflow:
- Sensors in the real building talk to the Digital Twin.
- The AI Assistant looks at the Twin's data and tells the group, "We are wasting energy."
- The DAO members (the people) log in, see the data, and vote on a new rule (e.g., "Turn off lights automatically after 6 PM").
- Once the vote passes, a Smart Contract (a self-executing digital agreement) automatically sends the command to the building's systems to turn off the lights. No human has to physically flip a switch.
6. Did It Work? (The Test Drive)
The team tested this system in a real building at Virginia Tech (Bishop-Favrao Hall).
- The Experiment: They set up sensors, created the digital twin, and let a small group of people vote on changing the temperature settings and turning off devices.
- The Results:
- Usability: People found the system easy to use (scoring high on a standard "usability test"). The digital twin was the most popular part because it was easy to understand visually.
- AI Performance: The AI assistant was very good at analyzing data and suggesting energy-saving ideas (getting a 92% accuracy score compared to a gold standard).
- Cost: It was relatively cheap to run the digital votes and transactions on the test network.
- Challenges: The experts noted that while the idea is great, getting everyone to agree on rules can be tricky, and some people are still skeptical about trusting AI suggestions without double-checking them.
Summary
In short, this paper presents a blueprint for a building that runs itself based on group votes, guided by a digital clone of the building and a smart AI assistant. It moves away from "one boss decides" to "everyone decides together," using technology to make sure the building is safe, efficient, and actually meets the needs of the people inside it.
