The emerging concepts of resilient cities, involving the ability to withstand and adapt to natural hazards (including those exacerbated by climate change), are attracting considerable attention. Beyond the contribution of residents, the resilience of cities to natural hazards undoubtedly depends on their built environment. Current building design standards ensure the survival of occupants in the event of extreme events, not that structures remain intact. This assumes "disposable" buildings. However, as some climate-related disasters increase in frequency and intensity, losses increase significantly. Assessing the resilience of buildings to natural hazards not only allows for the projection of potential damage, but should also allow for the assessment of associated environmental impacts. This integrated approach would identify concrete solutions to optimize both resilience and sustainability in the built environment. Rather than repairing or rebuilding them at a later date, existing buildings could be adapted in anticipation of a changing climate. Similarly, regulatory requirements for new buildings could be adapted to encourage designs that are both resilient and sustainable. Interested in this emerging and highly promising field, Xavier decided to pursue graduate studies at LIRIDE. His ambitious project is to synthesize existing research to identify gaps, develop a methodological framework for modeling environmental losses, integrate climate change into his modeling, and ultimately propose a list of concrete solutions to develop or implement to adapt to and combat climate change.
