Concerning the high temperatures during the summer season, the study implies green roofs as an effective sustainable design tool to mitigate urban heat island (UHI) effects.

Questo studio presenta un approccio integrato applicato per valutare l'implementazione di soluzioni basate sulla natura per infrastrutture verdi nelle aree industriali. La metodologia del Service Design sarà considerata come strumento di pianificazione per le infrastrutture verdi (IG), per proporre un piano d'azione in un ambiente urbano consolidato. Per quanto riguarda le alte temperature durante la stagione estiva, questo studio suggerisce che le coperture verdi siano un efficace strumento di progettazione sostenibile per mitigare gli effetti delle isole di calore urbane (UHI). Studi precedenti hanno identificato i benefici delle coperture verdi per il raffreddamento e il risparmio energetico degli edifici, con poca considerazione dell’influenza sul microclima del vicinato e sul comfort termico. In questo studio sono svolte una serie di analisi urbane e ambientali, focalizzate sugli impatti dell’utilizzo delle coperture verdi su scala locale, per la riduzione della temperatura dell'aria e il comfort termico esterno nell'area industriale di Bolzano Sud. Sono stati svolti modelli numerici e di fluidodinamica computazionale con strumenti di simulazione come ENVI_met per eseguire analisi nell'area, su scala microclimatica, tramite l’Universal Thermal Climate Index (UTCI). L'approccio è testato su due scenari: (i) uno scenario realistico dell'area industriale senza aggiunte di coperture verdi, (ii) uno scenario verde con l’integrazione di coperture verdi nel quartiere. Le coperture verdi semi-intensive possono ridurre la temperatura dell'aria a livello pedonale da - 0,4 a - 0,7 ° C nelle zone calde, offrendo un ambiente termico confortevole per i residenti urbani. Lo sviluppo e i risultati di progetto, divisi in pratica e indicazioni partecipative, dimostrano che gli effetti di raffreddamento delle coperture verdi migliorano il microclima del vicinato. Questo studio si concentra sui vantaggi che l'integrazione delle infrastrutture verdi portano al microclima come parte dell'adattamento delle città ai cambiamenti climatici.

Abstract
This study presents an integrated approach applied to assess the implementation of Nature-based Solutions for green practices in industrial areas. The Service design methodology will be considered as a planning tool for green infrastructure (GI) in an action plan proposal in a consolidated urban environment. Concerning the high temperatures during the summer season, the study implies green roofs as an effective sustainable design tool to mitigate urban heat island (UHI) effects. Previous studies have identified the benefits of green roofs in cooling and energy conservation at the building scale, with limited exploration of the influence on neighborhood microclimate and human thermal comfort. This research implies a set of urban and environmental analyses, focused on the impacts of neighborhood-scale green roof implementation for air temperature reduction and thermal outdoor comfort in the industrial area of Bolzano South. Numerical and computational fluid dynamic models were conducted with simulations tools as ENVI_met to carry out microclimate scale analyses through the Universal Thermal Climate Index (UTCI) in the area. The approach is tested in two scenarios: (i) actual scenario of the industrial area with no additions of green practices, (ii) green scenario with green roofs implementation in the neighborhood. Semi-intensive green roofs can reduce the air temperature at a pedestrian level by - 0.4 to - 0.7 °C in warm areas, bringing a comfortable thermal environment for urban residents. The development and results of the initiative divided into practice and participatory indications demonstrate that green roof cooling effects improve neighborhood microclimate. This paper focuses on the microclimate benefits of integrating green infrastructure practices as part of adapting cities to climate change.File | Dimensione | Formato | |
