Clusters represent research networks made up of an articulated series of skills, especially interdisciplinary skills that the SITdA Members have developed over time. Through the clusters, SITdA provides a series of specific and interdisciplinary skills that can assist both the Customer in better explaining his/her needs (quality of public demand), and the operator of the building sector, in proposing appropriate design, realization and management solutions (effectiveness of the response).Remember that it is possible to join only TWO clusters.
