Smart Redevelopment of Existing Buildings. Use of BIM in Economic Value Judgments

Industry 4.0, digitalization, smart building, virtual reality: these are terms that are also entering into the common use of a traditional sector such as that of real estate, a sector that today is at the centre of a revolution of approaches, methods, and processes. There is a change in the way of understanding the building that goes from being a simple shell to an advanced technological object. The advantages of living in a smart home compared to a traditional home are clearly numerous both from an economic point of view and from a psychophysical point of view but the real challenge, Nowadays, it is to be able to redevelop in a smart key existing buildings or belonging to the historical real estate. The topic of smart building becomes more complex when we talk about existing buildings because the constraints of intervention are many and therefore the decision margins to promote redevelopment actions are significantly reduced. With a view to redesigning existing buildings to make them economically viable, the BIM technology is a particularly effective tool, embracing a philosophy that bears witness to the concept of digitalization of the built environment, Today, the foundation of innovation in the construction industry. The estimation of the costs to be incurred for different improvement scenarios can be conducted through the BIM automatically. This makes it possible to simplify the analysis of economic feasibility in the processes of transformation of a property by orienting more effectively the identification of the best use of the property.
