The COBie standard achieved in several “firsts” in the use of open standard building information. COBie was the first standard to define objectively testable quality control standards that allow automated format verification by software companies and content validation by project teams. COBie was the first standard to address specific requirements for non-geometric building information. COBie was the first standard to document and model each lifecycle process where building equipment information is created, updated, and applied to predict of potential reduction in direct and overhead costs resulting from its adoption on projects and portfolios. COBie has been the only IFC-based non-geometric standard that conformed to International Alliance for Interoperability and buildingSMART alliance technical standards for Information Delivery Manuals and Model View Definitions. Aside from geometric coordination, which has now been largely integrated directly into design software, COBie is the most widely used open standard for the delivery of building information in use today.

For those who may not be familiar with the COBie project this appendix provides a reading list demonstrating these claims. Where possible URL’s for the document of record is provided (as of 22-Jun-20).

Documented Extensions

During the development of COBie, it was realized that many different types of property sets might be collected related to building rooms and equipment. The reports below identify some of these efforts.

2008. Properties reflecting the needs of facility management offices captured during COBie pilot testing. “Pilot Test of the Construction Operations Building information Exchange (COBie) Format for Army Installations,” Report not available by URL.

2012. Properties used for the prediction of energy and water resource use during building operations. “Life-Cycle Model of Mission-Ready and Sustainable Facilities: Planning Space Resource Utilization.”

2012. Evaluation of product property requirements. “Common Object Library Description.” Information contained here supported the Specifier's Properties information exchange project.

2012. Sustainable building product data extensions. “Sustainability Product Properties in Building Information Models.”

2013. Properties needed for (partial) automated production of sustainability scorecard. “Data Sharing for Sustainable Assessments: Using Functional Databases for Interoperating Multiple Building Information Structures.”

2013. Predictive model of impact of COBie-enabled project life cycle. “Assessment of Life Cycle information exchanges (LCie): Understanding the value-added benefit of a COBie process.” The resulting COBie Calculator predicts the project-specific and portfolio-wide COBie business case.
