Venice is known for its urban heritage fragility. The city is experiencing an increase in yearly average temperatures affecting outdoor–indoor comfort and average energy expenditure. Owing to existing literature demonstrating how local microclimate depends on urban density, form, and materials, this investigation studies the influence of the changing local climate on Venetian vernacular open spaces, known as Campi. Based on the comparison of contemporary weather and the Intergovernmental Panel on Climate Change’s (IPCC) future predictions for the 2050 scenario, this investigation highlights how Campi’s open spaces and the surrounding buildings, canals, and green public areas contribute to building climate resilience. By employing advanced modelling, the study analyses microclimate and outdoor comfort with respect to users’ perception of Physiological Equivalent Temperature (PET). The ENVI-met tool is used to simulate the thermal behaviour of two representative Campi: SS. Giovanni e Paolo and S. Polo. Despite significant temperature growths, Venetian urban fabric characteristics seem to play a crucial role in strengthening the climate resilience of open spaces, thus preserving outdoor comfort quality in a warmer future. The analysis shows how the historical matrix of open spaces and buildings cooperate. Thus, this study offers a contribution to how built heritage should be considered in light of climate change.
A city is an organism made of social, economic, cultural, and environmental fabrics, the interactions of which determine the form and functioning of city life. Different disciplines are then involved in analyzing the complex processes of the 21st-century city. The aim of this study was to explore the use of an analytical method that can act as a catalyst for the main players involved in the environmental urban morphology (EUM). This multidisciplinary methodology focuses on the study of public space in dense urban fabrics as a key context for understanding a city. Operationally, the work shows the potential of integrating morphological analysis, pedestrian flow analysis, and environmental analysis and applying them in dense and compact urban fabrics. The first of these analyses methods was carried out using urban survey tools and the geographic information system (GIS) in order to detect the physical forms of the city and develop a number of morphological maps. The second, using the global positioning system (GPS) and on-site detectors, maps pedestrian movement within public spaces. The latter mainly focuses on the microclimatic analysis of public spaces and outdoor comfort, carried out using environmental software such as ENVI-met (4.4 version). The ultimate goal of this study was to achieve the definition of a dynamic, multidisciplinary, and multilayer methodology for the analysis of dense urban fabrics which we believe could be very useful for addressing the regenerative processes of the contemporary city.
Since the entry of Emilia-Romagna Regional Law No. 24/2017 Disciplina regionale sulla tutela e l’uso del territorio, the processes guiding the development of the territory have profoundly changed, in principle, in the structuring through processes of participation and how contents are expressed and represented. Concepts such as the containment of soil consumption as a non-renewable resource; regeneration of urbanized territories; protection and enhancement of land, including agricultural land; protection and enhancement of historical and cultural elements; and promotion of greater levels of knowledge of the territory and its existing built heritage are the main principles of the law that give foundational importance to the entire process of forming the knowledge framework and strategic lines that structure General Urban Plans, which are designed to express planning contents through an ideogrammatic type of cartography. The analysis of the law and its contents also becomes an opportunity to reflect on the tools through which the governance of the territory is implemented, from GIS to web GIS up to the changes in the graphic language through which the planning principles are expressed, with specific reference to the planning tools of Parma, on which the new General Urban Plan (PUG) is being defined.
