Design Criteria and Strategies

ThischapterisdedicatedtothreeaspectsofHIMresearch.Firstofall,an analysis of the great step forward in the microclimatic functions of architectures, between the eighteenth and the nineteenth centuries. This is at the basis of the conflicts that more and more often we see between physical architectures and their microclimate, which end up into slow but inexorable decay of buildings. Second, the nature of these phenomena, due to the imposition of an inadequate microclimate to a building, with an adequate support of literature. In the third and final part, strategies and interventions to reduce the risk of decay are presented along with evaluation criteria to intervene on historic indoor microclimate when this is needed.
