Subject: Open Floor Plans, Building Telemetry, and BIM
BIM is something big, fat and process-driven. COBie, meant to be an interchange format has been hampered by formatted in EXPRESS (ISO10303-21). No one wants to process that or use it or validate it. NIBS and the IFC Process have been working with hard to adopt, hard to promulgate standards for some time. (There is nothing wrong with EXPRESS – it’s simply unfashionable today, enterprise and service interactions have gone another direction) Last summer, CERL used the OASIS CAM Specification to create clean schemas that are ready for service interactions. The results are NIEM conformant, which means ready for enterprise integration. http://buildingsmartalliance.org/index.php/projects/cobielite/ This TC has an identified interest in Open Floor Plans, currently more an aspiration than a specification. To my mind, Open Floor Plans has several elements. 1) There is a UI element, to describe the spatial stuff. How many rooms on the 4th floor? Where is room 208? Which rooms share the same ventilation? 2) There is a descriptive element. This could be a formal profile of COBie Light 3) There is an ongoing telemetry issue, including a need for BIM-derived metadata in the telemetry. oBIX and the Energy Services / Streams notions described in WS-Calendar and in Energy Interoperation can each serve the telemetry. A subset schema of COBie Lite could provide the metadata. There are certainly other valid opinions on how to fit this together. In any case, I recommend that TC members interested in this portion of Building-Emergency situation awareness submit comments on the COBie Lite specification, now out for initial public review. tc "If something is not worth doing, it`s not worth doing well" - Peter Drucker
