A Methodological Approach to represent Climate Change Impacts on Buildings

The main aim of the research is to propose a methodological approach to permit an assessment of the climate change impacts on buildings and their lifecycle, also by making the process computable. Climate change is a problem that designers and professionals in the AEC sector have begun to tackle more consistently and intensively in recent years. From the perspective of building sustainability in its entire life cycle, in fact, the problem of changing conditions in which the building 'lives' cannot be ignored, since many times they can be completely different from those in which it was designed and built. Recent research has shown how the use of BIM models, more systematic and relevant in the last few years, can be one of the best strategies for the management of new constructions and renovations in the different phases that characterise a building, from its design to its realisation and up to its renovation or change of use. That is not only due to the accurate 3D model, but especially thanks to the considerable availability of data and information related to the Building Object in question. The management of the simulation through a game engine, on the other hand, allows the user to live a direct experience in real-time. In this research, therefore, through the use of BIM models (Autodesk Revit) as a database (DB) of building-related data and combined and enriched with those obtained from other DBs from case studies and literature, it is possible to obtain a useful database which allows, through algorithms implemented within a game engine (Unity 3D), to visualise existing problems according to the date of construction and/or renovation.
