Open223 Models

Open223 Models#

ASHRAE standard 223P is a proposed standard that formally defines knowledge concepts for representing building system information such as the connections between mechanical equipment, spaces within a building, and their measurement and control points. It is a metadata schema and semantic ontology that defines the modeling constructs and rules needed to construct semantically interoperable, machine-readable semantic models that provide software applications the ability to determine essential information about the meaning and context of building data to support the deployment of various advanced features such as advanced building controls, fault detection and diagnostics, and automated commissioning.

This site contains example buildings, systems, and other assets modeled in 223 with supporting documentation.
