Walkability for inclusive cities: A quantitative methodology to address urban inequalities in Ponticelli, a peripheral neighbourhood district of Naples (Italy)
No full textWalkability assessments are crucial for fostering inclusive and sustainable cities, yet they often fall short in peripheral neighbourhoods, where inequalities are most pronounced. Traditional models frequently prioritise efficiency metrics, overlooking the qualitative and experiential factors that shape pedestrian behaviour. This article proposes a novel, hybrid methodology to address this gap. Our approach integrates quantitative GIS-based audits with qualitative data from resident surveys to create a more holistic walkability assessment.
The methodology produces two key metrics: a Walkability Index (Wi), which evaluates the quality of pedestrian paths based on weighted factors of safety, comfort, attractiveness, and pleasantness derived from resident perceptions; and a Wi-adjusted Urban Services Accessibility Index (USAI), which measures accessibility to essential services within a 15-min walk, adjusted by the Wi of the routes. Moreover, our method aims at moving beyond a simple link-node analysis by integrating open spaces, such as parks and squares, into the pedestrian network, offering a more comprehensive representation of the urban environment pedestrians experience daily.
Applied to Ponticelli, a peripheral neighbourhood of Naples, Italy, the methodology effectively identifies priority areas for intervention where high population density coincides with poor walkability. The findings offer a replicable framework and operational support tool for policymakers to target investments, supporting the development of more equitable and truly walkable cities

No full textA European Photovoltaic Atlas: Technology-Specific Yield Analysis by Tilt and Azimuth
No full textOptimizing photovoltaic (PV) installations requires precise understanding of the annual energy yield, which depends heavily on geographical location, panel technology, tilt, and azimuth. This study establishes the framework for a “European Photovoltaic Atlas”. In this pilot phase, the dynamic tool is applied to representative European climatic zones to compare diverse latitudes and technologies. Consequently, we aim to create a robust database and interactive visualization tool that allows users to analyze technology-specific yields based on variable orientation parameters. The study employs a large-scale simulation campaign using EnergyPlus coupled with a PVWatts model. Two photovoltaic technologies (PERC and TOPCon monocrystalline) have been simulated in seven European reference cities: Naples, Madrid, Berlin, Paris, London, Stockholm, and Warsaw. For each city and technology, simulations have been performed for a complete grid of orientations. The tilt was varied from 0° to 90° in 5° increments, and the azimuth was varied from 0° to 360° in 5° increments. All panels have been simulated at a height of 15 m to represent typical rooftop installations. The main result is a comprehensive database that links location, technology, tilt, azimuth, and normalized annual energy yield. This database feeds an interactive application developed in Python. This tool generates 2D heatmaps showing the surface orientation factor of any selected city–technology pair, 3D surface plots comparing performance across multiple technologies or locations simultaneously, and 2D charts estimating hourly annual productivity by varying technology efficiency values. The “Photovoltaic Atlas” serves as a practical decision support tool for architects and engineers by enabling the rapid optimization of photovoltaic systems and clearly illustrating performance in the European context
