The case studies published here are intended to promote the sharing of knowledge between entities regarding the diagnoses and the consequent adoption of measures for the adaptation to the climate changes in respect to buildings and surrounding areas. In these case studies it is possible to find examples of diagnoses and implementation of adaptation measures related, essentially, with infrastructural and structural stability issues, energetic efficiency and comfort conditions in buildings, hydric efficiency, systems of water use and draining. These case studies should provide a demonstrative and a replicative effect in other entities and sectors, reinforcing the objectives of the adaptIS platform.
