Four technical standards were published in NBIMS-US V3, The first is COBie. COBie provides least common denominator information for manufactured product and equipment. Three domain standards were created for HVAC, water, and electrical systems. With these we can automatically check design documentation for known errors. By adding one more specification, BAMie, we can integrate sensor telemetry to predict and measure emergent building performance.
The Construction Operations Building information exchange (COBie) standard delivers O&M data for manufactured, scheduled products and equipment.
In addition to providing the basis for a future digital twin having a full model, including information about logical connections among components allows automated, computer-supported design quality control to be built into design authoring tools. See the initial Support Environment for Design and Review demonstration from 1996.
The Heating, Ventilating, and Air Conditioning (HVAC) information exchange (HVACie) standard models the supply, return, and hydronic systems with logical and physical location of each piece of equipment, pipe, and duct. A combination of a Coordination MVD for a restricted set of object types, COBie Data, and ifcPorts.
The electrical system information exchange (Sparkie) standard models electrical power and distribution systems with logical and physical location of each piece of equipment, panels, components, and conductors. A combination of a Coordination MVD for a restricted set of object types, COBie Data, and ifcPorts.
The Water System information exchange (WSie) standard models supply and waste systems with logical and physical location of each piece of equipment, fixture, and pipe. A combination of a Coordination MVD for a restricted set of object types, COBie Data, and ifcPorts.
Based on the standards above and the specification below, create a domain-independent platform to predict building emergent performance and compare planned performance to messy sensor data.
The Building Automation Management information exchange (BAMie) specification models building automation and control systems with logical and physical location of each piece of equipment, panels, components, and the connections made between the underlying system object and the control system object. A combination of a Coordination MVD for a restricted set of object types, COBie Data, and ifcPorts.
The following additional resources are provided for technical standard implementors. See the Analysis of Classification Systems for more information.
Due to changes in the licensing of CSI products, OmniClass tables referenced in COBie may no longer be available through the world wide web. The classification tables published in NBIMS-US V3 are provided for historical/educational purposes for those using the standards above.
If your team is unable to use the default classification tables above, you may specify these publicly available, free alternative - Uniclass. Click here to find past and current Uniclass tables.
