Building Information Modeling (BIM) is an increasingly common acronym among architects. Most offices and professionals are already migrating or planning to switch to this system, which represents digitally the physical and functional characteristics of a building, integrating various information about all components present in a project. Through BIM software it is possible to digitally create one or more accurate virtual models of a building, which provides greater cost control and efficiency in the work. It is also possible to simulate the building, understanding its behavior before the start of construction and supporting the project throughout its phases, including after construction or dismantling and demolition.
BIM methodology is mostly developed for and applied to new construction projects and its potential for renovations and retrofits is still less explored. If we take into account societal needs to improve the spatial quality and poor performance of the vast majority of existing building stock, especially with regards to energy consumption, BIM can contribute to making retrofits and renovations more efficient, intelligent and sustainable.
