Executive Summary

In the previous iteration of this Green Quadrant assessment, in 2024, the platforms evaluated were largely Internet of Things (IoT)-led integration and visualization solutions, providing a centralized view of building data to generate insights, support recommendations and inform operational and strategic decisions. Since then, the unified digital building platform market has expanded considerably, establishing a new baseline that is moving beyond insights and recommendations, towards action. This 2026 Green Quadrant assesses platforms that unify IT, operational technology (OT), IoT and power infrastructure data to not only inform decisions, but also to orchestrate and control building operations. Although adoption remains nascent among buyers, vendors are increasingly investing in AI-driven analytics, agentic workflows and autonomous capabilities in anticipation of more intelligent and automated building operations. This market evolution necessitates a new assessment of unified digital building platforms, to capture both the continued advancement of core capabilities since 2024 and the emergence of new differentiators driven by evolving buyer expectations. The report provides an independent, fact-based benchmark of 12 prominent unified building orchestration platforms, based on the proprietary Verdantix Green Quadrant methodology.
