Urban quality and environmental resilience at the edge = Qualità urbana e resilienza ambientale al margine
La percezione di un margine, un limite connesso al concetto di frangia urbana, ricorre in questo contributo ed è osservato da diversi punti di vista.
Il rapporto IPCC 2022 sui cambiamenti climatici ricorda che c’è un limite all’adattamento ai cambiamenti climatici quale soglia dinamica che si modifica in funzione della ‘salute’ degli ecosistemi. Tuttavia, il limite indica anche il passaggio fisico tra due condizioni, spesso ibride, incerte, e anche degradate, ma che possono rappresentare una opportunità di transizione (concetto dinamico). L’articolo descrive alcune strategie (vegetazione, materiali urbani, sistemi
di ombreggiamento) che possono essere impiegate nel superamento di barriere fisiche e per migliorare le condizioni sia ambientali sia fruitive delle aree di margine.The perception of a margin, a limit connected to the urban fringe concept, is recurrent in this paper and observed from different points of view. The ippc 2022 report on climate change states that there is a limit to climate change adaptation, a dynamic threshold that changes according to the ‘health’ of ecosystems.
On the other hand, the limit also indicates the physical passage between two conditions, often hybrid, uncertain, and even degraded, but which can represent an opportunity for transition (dynamic concept). This paper describes some strategies (shading systems, vegetation,
urban materials) that can overcome physical barriers and improve both the environmental and the fruition conditions of marginal areas
THE SCHOOLYARD: A RESOURCE FOR HEALTH AND EDUCATIONAL INNOVATION
L’impatto della pandemia da Covid19 ha
definitivamente svelato la criticità di molte
infrastrutture scolastiche connotate da ambiti spaziali
sottodimensionati e poco flessibili e/o con dotazioni
impiantistiche obsolete. La riapertura delle scuole in
condizioni di emergenza sanitaria ha avuto un impatto
significativo sulle modalità didattiche, sulle relazioni
interpersonali, sulle possibilità di movimento, sull’uso
di spazi ed attrezzature; ha, però, anche offerto
l’opportunità di rivalutare luoghi, come i cortili
scolastici, che diverse esperienze nel corso del tempo
hanno dimostrato essere risorse fondamentali per lo
sviluppo educativo e fisiologico degli studenti.
Lo scopo di questo lavoro è quello di confrontare uno
scenario critico, riguardo alle condizioni di vivibilità
delle infrastrutture scolastiche, ad una visione più
propositiva, articolata attraverso una serie di
riferimenti esemplificativi di interventi, che possono
essere assunti e declinati con un’ottica di lungimiranza.The impact of the Covid19 pandemic has
definitively revealed criticalities in those school
infrastructures that are characterized by
undersized and rigid spaces and / or are
equipped with obsolete equipment. The
reopening of schools in health emergency
conditions has highly impacted on teaching
methods, social relationships, student
movement, as well as the use of spaces and
equipment; however, it has also offered the
opportunity to reconsider some forgotten
places, such as schoolyards. In fact, these spaces
have shown to be fundamental resources for
the educational and physiological development
of students. The purpose of this work is to
compare a critical scenario, regarding the
livability conditions in schools, to a more
proactive vision, articulated through a set of
examples of potential interventions, or
perspectives
Il controllo dell'elemento naturale (acqua) per migliorare la resilienza ambientale urbana
“Requisiti e metodi per la progettazione ambientale degli spazi urbani”
The paper takes way from the outline of the state of the art on mobility issues and possibilities of reorganization from the point of view of quality of life improvement and environmental sustainability. The experiences already made in many other countries, both European and extra European, take to say that such reorganization has to be based on some main basic choices: to improve public transport and intermodality offer, to boost its use for the longer routes, and to promote non motorized transport modes for the short displacements, to discourage private individual traffic. To this aim it is necessary to affect the structure of the mobility system: components and speed, weights and hierarchies. The essay gives then an overview of various possible actions that can be taken to increase the share of the pedestrian mode in town and to regain space for hosting all the activities of displacement and stasis, with the aim to create a continuous pedestrian network, interlaced with a calmed vehicular mobility. The focus is on an Italian tool that could allow to do this, but that is not very much used yet: the Environmental Island, inserted in the indications given by the law on Urban Traffic Plans. Such instrument is up to date in respect with other European tools, as the English Home Zones, the French or German Zone 30 etc. Its potentialities are in particular analysed for the upgrading of residential districts, above all for meeting the main pedestrians’ requirements: safety and security, accessibility, comfort, use and aspect of the urban spaces. The essay suggests also a methodology, already applied in pilot projects elaborated for case studies in Rome, for integrating the two main aspects of the design: reorganization of the mobility and improvement of the urban quality on its whole. Finally it deals with three main issues: the behaviour and speed appropriate to the urban environment and the auto explicatory street as a measure of traffic calming; the design of a coexistence space; the environmental design of the intermediate spaces
Cooling Cities. Innovative Water-Based Cooling Systems in the Era of Urban Heat . Solutions for Outdoor Climate Adaptation
The Climate Change phenomenon continues to affect urban areas and their populations, the Urban Heat
Island Effect (UHI) related impacts, such as heatwaves, are known to affect the climatic conditions of cities and increase the thermal stress of citizens. This research investigates the implications of heat stress on citizens' thermal comfort by analysing the Universal Thermal Climate Index (UTCI); and, based on well-known urban cooling principles and techniques, proposes an innovative water-based cooling system design specifically to reduce peak temperatures during heatwaves in outdoor areas, promoting enhanced spaces (urban oasis) that improve citizens' thermal comfort during heat stress conditions. Applying a research through design approach to optimise and document results in a series of iterative design-test-optimisation processes. The cooling potential of the "downdraft-evaporative-windcatcher" (DEW).
Cooling Façade is simulated in a testbed combining four variables into twenty different configurations, the bestperforming configuration (in the UTCI values) is later applied to a case study in the city of Milan, Italy
