The acronym IFC stands for Industry Foundation Classes. It is an open file, digital format for describing building models. The open format used in the building industry and for facility management enables important information to be described and exchanged in a software-neutral setup. The exchange takes place in the form of a digital building model for which the buildingSMART International (bSI) – formerly International Alliance for Interoperability (IAI) – dictates the exact features and structure.
The format is ISO-certified and presents its own ISO standard for the first time with the new IFC4 version.
