All the elements present in open areas contribute to define the microclimate and they have to be designed to mitigate the microclimate. In particular urban materials have to be selected on the basis of the urban space use and its thermal behavior.
This paper shows the influence of urban pavements and building facades materials on the open spaces environmental performance and on thermal comfort conditions. In order to evaluate the contribution of the materials thermal simulations in dynamic regime were carried out of simplified configurations (corner of squares and streets. The paper shows how the urban space thermal performances change when only one or two walls are considered and if differences occur when the analyzed area is near or far from the wall; as well as when building height changes. This first part of analysis considers the open space as reference case and evaluates how the thermal performances change according to the changing context (from open space to the corner of the square). The second part points out the differences among the materials due to the physical properties; like albedo; thermal capacity and density. The last analysis concerns the evaluation of these configurations in terms of thermal comfort.
