Pathian Incorporated

Pathian is the creator of the world’s first planetary-scale energy benchmarking engine, now available through the Microsoft App Store. Built on more than four decades of engineering innovation, Pathian provides the universal data language the entire energy ecosystem can build on. We invented GEES — Global Energy Efficiency Standards™, Pathian Curves®, and the Syrx® Number System, forming a single measurement framework that works for building owners, utilities, OEMs, contractors, and AI systems alike. At the center of this framework is the Pathian Curve. To people, it’s a visual chart that shows exactly how their building and HVAC systems consume energy — and how effective their decisions truly are. To AI, it’s a weather-indifferent data array that powers weather-indifferent mathematics and the next generation of autonomous control systems you can chat with. Pathian’s engine delivers 10X higher accuracy while using 90% less compute, enabling fair, consistent comparison across any building, climate, or mechanical system. By placing Microsoft at the center, Pathian creates a single ecosystem where OEMs, contractors, and utilities thrive using the same standardized data — or build their own branded technologies at a fraction of the cost. Our platform includes AOS® (Airside Optimization System) for optimized HVAC engineering and a cloud-connected BACnet driver that ingests data from any BAS, maps points automatically, and generates Pathian Curves instantly. This allows every partner, from OEMs to integrators, to leverage the same weather-indifferent foundation. Pathian’s ecosystem enables utilities to automate M&V, OEMs to create branded insight engines, contractors to optimize systems faster, and building owners to understand the real impact of their decisions. Our mission is to provide the global energy ecosystem with one clear, consistent standard — empowering every partner to build more, optimize more, and deliver more value than ever before.
