The enormous variety of design systems and data formats utilised by the actors in the building design process has been recognised as a significant challenge for information exchange and project management. The introduction of the Industry Foundation Classes (IFC) data standard as a par- adigm shift has opened a first time opportunity for smooth data and information exchange over the full range of design related parameters and processes, reaching beyond the classical constructional, economic and safety- related requirements. Moreover, IFC allows for the extension of the standard in further areas, corresponding to the specific design, project or client require- ments. These user-driven extensions often close an important gap of the IFC standard and can subsequently be imbedded in new releases of the IFC data standard. This paper is focused on the extension of IFC for the purposes of controlling and managing material use, increasing material efficiency and closing material cycles over the life cycle of a building. Material efficiency is defined by the design scopes of material recyclability, element reusability and waste reduction. The practical implications of the data format extension and design-check performance are examined on the level of the data model and, subsequently, on the level of proprietary Building Information Modelling (BIM) software, based on a pre-defined case.
