ASHRAE’s BACnet Committee, Project Haystack and Brick Schema to provide unified data semantic modelling solution

Atlanta, Berkley, California, USA, 05 March 2018: The ASHRAE BACnet Committee, Project Haystack and the Brick initiative announced they are actively collaborating to integrate Haystack tagging and Brick data modelling concepts into the new proposed ASHRAE Standard 223P, for semantic tagging of building data, in a Press communiqué. ASHRAE Standard 223P: "Designation and Classification of Semantic Tags for Building Data" provides a dictionary of semantic tags for descriptive tagging of building data, including building automation and control data, along with associated systems, the communiqué said. According to ASHRAE, integrating Haystack tagging and Brick data modelling concepts with the upcoming ASHRAE Standard 223P will enable interoperability on semantic information across the building industry, particularly in building automation. ASHRAE explained this unified effort aims to create a formally standardised application data modelling solution, which can be used for exchanging data over established communication protocols, like the Haystack web services or BACnet or applied on data stored in databases and cloud applications. ASHRAE said the first public review of the initial draft of 223P is envisioned for late 2018 and the final ASHRAE Standard 223P is intended to be adopted as an ISO standard.
