Willow Knowledge Graph

The foundation for intelligence

See How it Works

Navigating building operations is no easy feat

Buildings rely on unique systems, data structures, and operational workflows to operate—many of which fail to speak to one another.

The Willow Knowledge Graph eliminates these silos by creating an independent data layer (IDL) that normalizes how the many different systems used for operations and management of buildings organize and describe their data. This enables Willow to rapidly scale across thousands of buildings where all have unique layouts and systems.

The Willow Knowledge Graph is built on two key layers:
Layer 1: Ontology → Layer 2: Twins & relationships →
Layer 1

The world’s most complete ontology for the built world 

At the core of Willow’s intelligence is the most comprehensive buildings ontology ever developed—a powerful set of models that describe what exists in the built environment and how those entities relate to one other.

3700+

Models

1400+

Properties

120+

Relationships
Layer 2

Twins & Relationships

The Knowledge Graph is comprised of twins and relationships where every twin has a defined model from the ontology and at least one relationship to another twin in the graph. Twins are instances of a model in the real world.

As the Knowledge Graph expands with more twins and relationships, Willow’s AI grows stronger, unlocking deeper insights, predictive capabilities, and automated decision-making at scale.

Turn your data into AI-driven intelligence 

With the Willow digital twin platform, your building data is structured, stored, and activated into powerful insights and data-driven decision-making. Unlock a more efficient and sustainable way to manage buildings.
