Proposed ASHRAE Standard 223P
“Designation and Classification of Semantic Tags for Building Data”
- The purpose of this standard is to provide a dictionary of uniform semantic tags. These tags enable interoperable use of descriptive information on building data.
- This standard provides a dictionary of semantic tags for descriptive tagging of building data including building automation and control data along with associated systems.

ASHRAE SSPC 135 AP-WG
• ASHRAE SSPC 135 is the BACnet Committee• AP-WG is the Application Profiles Working Group of SSPC 135• Historically, this group discussed ways to define "Application
Profiles" for standardized representation of complex structures:– Use of BACnet Objects and Properties– Use of BACnet Structured View Objects– Use of Semantic Tags in BACnet Objects– Use of Linked Data, Semantic Interoperability– Reach out to Project Haystack and Brick– Proposal for new ASHRAE Standard, independent of BACnet
• AP-WG in charge of drafting Proposed ASHRAE Standard 223P

ASHRAE Standard 223P and BACnet• 223P supports semantic interoperability for building data• Support in particular protocols or data schemas is specific to those• SSPC 135 will need to define how 223P is supported in BACnet objects,
device descriptions, and the Abstract Data Model

“Designation and Classification of Semantic Information for Building Data”
Building Automation Systems Information Model (BAS-IM)
• The purpose of this standard is to define an abstract, linked data information model defining concepts and requirements for describing building automation systems to promote semantic interoperability.
• The scope of this model includes equipment such as chillers, air handlers, and VAV controllers, the sensors and actuators used for control applications, direct digital control devices, and the connections between them.

BAS-IM Model Scope

Figure by Joel Bender
BAS-IM Model Scope
May 13-15, 2019 74
• Physical Model– Building, Space, Environment, Equipment, Piping, Wiring, Connections, Flows, Devices, ...
• Sensors and Actuators– Connect the physics with the building automation system
• Control Devices and Objects– Control device, points and object models– Control program and control function block models
• Basic models by 223P only• Based on selected shared and foundation ontologies• Co-exist with other application ontologies, • Mappings, bridges, etc. possible• Vocabulary definitions and concrete models by application domain bodies,
such as ASHRAE committees, Project Haystack, Brick, CEN, etc.

• Semantic Information Model Concepts• Foundation Models Support Profiles• Shared Ontologies Support Profiles• BAS Information Model and Support Profiles• Domain Models Support (-> Haystack 4.0)
• And maybe: Support Profiles for Lower Layers
Application Profiles & Haystack 4.0
May 13-15, 2019 76
• Application Profiles are structures and points of AHUs, VAVs, RTUs, etc.
• Haystack 4.0 provides mechanisms for definition of application profiles.
• Project Haystack is the preferred and capable community for defining application profiles.
• Referenced by 223P, alignment to BAS-IM by AP-WG• Freezed Haystack models in RDF as part of 223P
