The Semantic Interoperability Working Group is developing a comprehensive way to apply semantic formalisms to represent the context of building system data and relationships between the associated building systems and components. The objective of this work is to enable applications to find and understand the information in an automated way. This will facilitate the development and implementation of building analytics tools and enterprise knowledge applications that can implement a number of building system functions.
This working group is the home for development of proposed ASHRAE standard 223P Semantic Data Model for Analytics and Automation Applications in Buildings. It is also developing guidance for enhancements to the BACnet standard that relate to the use of the Tags properties in BACnet objects.
