The fourth issue of the magazine aims to analyze the state of the art of professional practice and research activities a year after the issuing of the D.M. 560/17, which establishes methods and timing for the progressive introduction of electronic modeling methods and tools for the building and infrastructure sectors, making obligatory specific electronic methods and tools for complex works related to tender base amount mandatory ≥ 100 million euros.

Different forms of BIM-oriented systems constitute the object of investigation, highlighting the ways in which these issues, with their apparently purely technical or technological connotations, can instead have multiple application derivatives, creating new areas of interest for researchers, experts, operators and professionals.

BIM approach is, by its nature, three-dimensional, enriched and implemented by informative variables and parameters which, based on different contexts, needs and different application scenarios, can be characterized by many deeply interdisciplinary branches. A good example are studies and analyzes on contemporary architecture; applications related to energy sustainability; analyzes and processes applied to Facility Management.

This is the direction of the papers of Andrea Barbero, Francesca Maria Ugliotti and Matteo Del Giudice with BIM-based collaborative process for Facility Management, Sara Conte and Michela Rossi with BIM model for enhanching modern architecture. Olivetti’s case, Fabio Luce with Parametric modelling for energy retrofitting of existing building. Two possible strategies, Alessandro Sepe and Andrea Tiveron with BIM and technical management of the built.

Presence of a vast cultural heritage in Italy requires significant conservation and restoration processes. This leads to the organization of digitized data according to HBIM (Heritage Building Information Modeling) processes, for which an operating method has not yet been clearly defined. The sector is still in research and definition phase of contents and in this direction lead the contributions of Elena D’Angelo, Federica Marini, Paola Morrone, Andrea Natalucci and Alessandra Ponzetta with The Garden of Ninfa: a BIM application for the conservation of the ruins, Maria Laura Rossi with Computational design for diffused historical heritage. Genotypic aspects and theoretical foundations.

Three-dimensional modeling, directed towards advanced systems and controls for the visualization of architectural project, can derive from BIM models and relate effectively with them. In any case, they are environments of vital and fruitful processing in terms of research, evolution and expected results. Critically reflect on these instances the contributions of Cristian Farinella with Style issues. The relationships between photography, cinema and CG film in the 3D visualization and Lorena Greco with From photographic set to 3D visualization. Modeling of light sources in an IT environment and relationships with photography.
