Willow: Building digital twins, contextual diagnostics and operational workflows

Willow connects building data in a knowledge graph and digital twin, supporting diagnostics, maintenance workflows and an AI copilot.

Best for: Large property portfolios connecting operational data with asset relationships and maintenance workflows.
Less suited to: A standalone low-cost meter dashboard without asset modelling or enterprise integration.
Deployment: Azure-based enterprise software with portfolio integrations and tenant-specific data environments.
Data in: Live building telemetry, asset records, spatial data and maintenance documents.
Pricing: Project pricing requires a quotation; Microsoft Marketplace procurement is available.

Overview

Willow organises building information around the relationships between assets, spaces and systems. Its platform combines live telemetry with static records and spatial information in a digital twin. The purpose is to make a fault understandable in its operating context: which equipment serves a space, how that equipment is behaving and which maintenance action relates to it. This is broader than drawing a three-dimensional building model or collecting isolated meter readings. The platform targets portfolios where building systems, asset records and maintenance tools need to contribute to a common operational view across multiple sites.

Offering

The Building Energy and Operations Activate Pack applies the platform to energy and asset-performance tasks. It connects findings with maintenance workflows and operational changes rather than stopping at a chart. The wider product architecture uses a knowledge graph to preserve relationships between equipment and the services it supports. In the DFW airport account, Willow describes a large digital-twin deployment and the use of its analytical capabilities across airport assets. The airport’s stated future maintenance-reduction ambition is a target, not a completed measured saving. The useful evidence is the scope of the connected operational model and its application to a complex estate.

Technology

Willow Copilot adds a conversational interface grounded in the organisation’s knowledge graph and uploaded documentation. It can help teams investigate an asset, inspect diagnostic context and retrieve relevant operating or maintenance information. The product description includes citations when answers reference uploaded documents and describes tenant-specific environments. It also supports the workflow around an on-site visit, such as understanding earlier diagnostics and recording a resolution. These features depend on the building model and available source material; they should not be interpreted as an independent engineering judgement that replaces verified instructions or site-specific maintenance responsibilities.

Markets

The Microsoft integration connects Willow with Azure Digital Twins, Microsoft Foundry, Dynamics 365 Field Service and Microsoft Fabric. Its published architecture describes prioritised work orders and operational data made available to enterprise analysis. The HPE relationship combines secure networking with the Willow data model and includes HPE’s own workplace deployment. HPE Aruba Networking Central and Juniper Networking Mist are named integration points. This gives the platform a route into IT and facilities workflows as well as building controls. The relationships are specific software and network connections, rather than blanket compatibility with every device carrying those vendor names.

Company

Willow’s official company profile gives 2017 as its founding year and Sydney as headquarters. The current leadership page identifies Bert Van Hoof as CEO, Rick Szcodronski as chief product and technology officer, and LeighAnn Walters as CFO. Its published timeline records a 2018 WillowTwin launch on Azure and subsequent work with property and enterprise partners. Current market emphasis includes education, airports and healthcare, with commercial portfolios also represented in its history. The company combines building-domain modelling with enterprise software integrations, which explains why its offering is presented around operational workflows and portfolio context rather than one particular sensor or controller.
