See how Willow can help you cut costs, save energy, and operate your buildings more efficiently and sustainably.
While HVACs contribute on the order of 40% of a building’s operational expenses, whole‑building strategies can yield up to 70% reductions. Modern campuses, airports, stadiums and healthcare facilities operate as interconnected ecosystems. Willow’s platform is built to unify systems, correlate signals across them, and deliver operational intelligence. Stepping beyond traditional HVAC-centric fault detection, Willow has Skills and Insights that work holistically across systems such as mechanical, plumbing, refrigeration, and electrical, and more.
Let’s walk through five use cases where Willow delivers value that goes beyond traditional HVAC-focused fault detection:
Water is one of the highest risk building systems. Willow gives operators a way to stay ahead of water leaks with continuous monitoring of meters and sensors using Skills to spot early warning signs. These include anomalies and unexpected consumption patterns. Early detection prevents escalation in the form of burst pipes and occupant disruption, giving teams time to intervene while the problem is still preventable.
As an example, Spike in Water Consumption – Potential Water Leak continuously analyzes water consumption data to flag unexpected increases in water usage, which may indicate a leak in the piping downstream of the meter.
A rich ontology supports modeling pipes, fixtures, and valves. The Knowledge Graph can describe assets relationships spatially and functionally. As a result, when a leak is detected, it is easy to pinpoint the exact location of the upstream shut off valve. Instead of hunting through mechanical rooms and documents, operators can converse with Willow Copilot to check the valve’s position and what downstream areas are impacted when it’s closed.
Willow strengthens refrigeration reliability by giving teams realtime visibility into cooler performance and asset temperature stability. Skills and Insights make it easy to spot drifting temperatures, failing compressors, or doors left open before they threaten the integrity of the case contents.
An example is Display Case Temperature Out of Target Range. This Skill monitors the temperature inside the refrigerated display case to ensure it remains within the designated target range.
Automated alerts in the form of Insights highlight anomalies early, reducing spoilage risk of perishable contents. Technicians get clear context on root causes, while managers can see patterns across facilities. The result is tighter compliance and consistently protected inventory that stays within required temperature ranges.
Willow elevates fume hood safety and performance by giving facilities a view of how each hood is operating. Data from sensors is ingested and normalized. Decision intelligence in fume hood-specific Skills generates Insights. As a result, Willow enables 24/7 analysis of each fume hood, enabling precise management. With the Fume Hood Sash Open 24×7 position monitoring Skill, Willow tracks when sashes are open or closed.
The Skill looks for sashes left in open position for the last 24 hours and generates insights to alert users. Teams gain clear signal per asset, while managers can compare performance across labs and identify chronic offenders. In turn, this enables safer workspaces and fewer unplanned disruptions.
Willow ensures that IoT sensors stay functional by turning reactive maintenance into a proactive workflow. The IoT Sensor Battery Low Skill monitors battery-powered sensors within a building and proactively generates Insights when a sensor’s battery level drops below a predefined threshold. This Skill plays a critical role in maintaining reliable sensor operation across environments that depend on occupancy sensors, temperature probes, air quality monitors, and more.
This minimizes downtime and ensures that sensor-driven data streams, such as space occupancy or environmental conditions, remain uninterrupted.
The Insight provides detailed context, enabling teams to prioritize replacement tasks efficiently, reduce manual checks, and improve operational continuity.
By integrating real-time data from the energy grid and building systems, Willow helps facility teams make informed decisions about energy use. Skills and Insights enable load shaping and responses to grid signals. With Willow, buildings become grid aware as soon as they onboard.
Willow’s Load Shed – Power Consumption Approaching Monthly Peak Demand Skill generates an Insight to identify that current power consumption is approaching last month’s peak demand, which could trigger higher demand charges from the utility company. The system recommends immediate actions to reduce load, such as increasing temperature set points and turning off unnecessary equipment. The Time Series graph illustrates power usage over several days, highlighting periods of high demand. This insight helps facility teams act proactively to avoid costly peak charges and improve energy efficiency through real-time control.
Willow’s ability to support systems and solutions beyond HVAC unlocks deeper operational efficiency by connecting interdependent systems. By unifying Insights, Willow improves overall building health and enables proactive issue detection. This holistic view also drives greater building-wide efficiency by revealing cross-system opportunities for energy savings and smarter asset utilization. Work orders become more informative, with a single history spanning all systems. This improves response time, tracks building health, and ensures thorough documentation for compliance. Willow Copilot’s enables conversational experiences to understand and reason across all systems. This enables organizations to realize the power of going beyond HVAC.
