L’émergence des identités culturelles au Paléolithique inférieur: la cas de l’Italie
No full textThe QlandQlife tool
No full textIn recent decades, the city and the broader concept of the territory have experienced a metamorphosis: from usable physical resources and controllable, designable space to a new interpretation of the urban system. This system is complex, so the inadequacy of linear planning becomes clear when faced with an increasingly strong need for multiple intelligible responses. The ideal of the city as a “single element” has been substituted by the concept of “system city”, going beyond the model of a city that can be decomposed and simplified to attain an interpretation of the system as a “complex unit”
UnicamTools
No full textUnicamTools is a comprehensive software suite developed to streamline climate analysis and urban comfort studies. Built upon the Ladybug Tools framework, it provides an accessible interface that simplifies complex environmental analysis workflows. The suite comprises four integrated tools: a statistical analyzer for identifying representative climate scenarios (White Tool), a weather data integrator (Green Tool), an urban heat island effect simulator utilizing MIT's Urban Weather Generator (Orange Tool), and a thermal comfort calculator incorporating shadow analysis, radiation studies, and Universal Thermal Climate Index (UTCI) assessments (Blue Tool). This toolset addresses the growing need for user-friendly environmental analysis software in urban planning and climate studies, reducing the technical barriers typically associated with such analyses. Developed within the CLICCHE Erasmus+ Project framework, UnicamTools represents a significant step towards democratizing access to sophisticated climate analysis tools while maintaining scientific rigour through established methodologies and validated calculation engines.

Mass and lightness: urban quality along the Aurelian Walls in Rome. Walking through Walls. (Rivista di classe A)
Full text linkLo studio intende focalizzare la sua attenzione sul sistema delle Mura Aureliane, prendendo come riferimento il piano regolatore che ne indica il ruolo di infrastruttura verde al servizio delle aree immediatamente prossime al centro storico. Si propone un rafforzamento del sistema in chiave ambientale, come opportunità per rigenerare spazi aperti di relazione utilizzando la mas-sa muraria come dispositivo ambientale e, al tempo stesso, come memoria e simbolo della Roma storica. L’obiettivo è la rifunzionalizzazione dell’elemento murario come un’isopleta urbana capace di generare comfort termoigrometrico in virtù dell’inserimento di elementi verdi e dispositivi funzionali in zone della città pervase da materiale lapideo/cemento/asfalto.

Assessment of outdoor thermal comfort and its relation to urban geometry
No full textMicroclimate conditions in urban open spaces are directly linked to the configuration of street axes and building heights and their attributes. Within street canyons, public places, and open spaces, the local microclimate depends directly on the physical properties of the surrounding surfaces and objects, producing well-known effects that can decrease or increase thermal loads. All of these phenomena can greatly influence the comfort of a city and the thermal comfort of pedestrians. Thermal comfort is an indicator that cannot be easily converted into physical parameters. However, it may be defined more qualitatively as the range of climatic conditions in which most people feel comfortable. One well-recognized thermal comfort index used to measure comfort levels inside a space is the predicted mean vote (PMV). Fanger's PMV index has been widely used in the last ten years. It is based on six factors: air temperature, air speed, humidity, mean radiant temperature, metabolic rate, and clothing levels. The comfort equation establishes relationships among the abovementioned environmental variables, clothing type, and metabolic rate. The authors present results of PMV simulations using a multi-objective optimization tool (i.e., modeFrontier). ModeFRONTIER is an integration platform used to optimize and arrange PMV algorithms linked to urban geometry parameters (e.g., the height-to-width (H/W) ratio of urban streets). The optimization process employs given constraints, custom procedural algorithms, and genetic algorithms to examine a wide urban space and identify interesting relationships among the variables considered. Urban geometry, meteorological data, and latent influences are examined and negotiated quantitatively to improve outdoor thermal comfort. © 2013 WIT Press
