Post-war industrialized housing between 1955 and 1985 in Belgrade and its special form of integrated prefabrication has been analyzed with a strong interest in transformation capacity of industrialized building model (IBM) on different technical levels. Research field is massive housing up to 23 floors, 400 dwellings per building and different housing layouts—to be evaluated for potential retrofitting at the dwelling level. IBM for massive housing built with IMS construction technology represents an integration of systems’ components into hierarchy assemblies by simple joints. IMS Building Technology by IMS Institute is the system for high-rise structures with prefabricated elements of the skeleton. In order to assess the current situation regarding the selection and implementation of energy savings measures and the role of industrialized technology in supporting the rehabilitation of post-war housing in Belgrade—building configuration model and IMS construction technology has been analyzed, providing in-depth information on the way building components and systems are put together into IBM. In which way retrofit may be approached? IBM is represented with graph model (GM) diagram to describe a number of value-added processes according to independent systems/components and flexible connections. This paper highlights the technological aspects of “open” prefabrication industry and building with the systems that should be assessed in the future retrofitting of massive housing based on industrialization and energy efficiency. The paper proposes an IBM that provides concrete description of massive housing buildings, the requirements for information to be provided to approving refurbishment processes. The research also addresses both: challenges as well as opportunities for advancing Building Information Modeling (BIM) standards in off-site re-construction of massive housing with new “infill” industry.
