Introduction
My PhD research is focused on three big themes: Health, Sustainability and Urban planning. In particular, my activity is aimed at studying the impact of vegetation on thermal conditions and air quality in the urban environment. I'm using and exploring the potential of the CFD model ENVI-met. __________________________________________________________________________________________ [PAPER INVITATION] - SPECIAL ISSUE https://www.mdpi.com/journal/atmosphere/special_issues/urban_vegetation_climate

Article
This paper assesses the effects of trees (Platanus x hispanica) of different leaf area density on ventilation, NOx and PM2.5 concentrations across heights in Marylebone Rd street canyon in London (UK). Computational Fluid Dynamics steady state simulations are performed with OpenFOAM. The ventilation is evaluated through flow patterns and the analys...

This paper is devoted to the application of the modelling approach, as one of the methods for the evaluation of thermal comfort, to neighborhoods located in two cities characterized by a different climate, i.e., a Mediterranean city in southern Italy (Lecce) and a northern European city in southern Finland (Lahti). The impact of the presence of veg...

This study carries out a quantitative analysis of the impact on microclimate (air temperature and thermal comfort) of a row of 165 historical Pinus pinea L. located in a central neighbourhood of Rome (Italy). The analysis starts from a qualitative general analysis on the stressful conditions leading to tree decline in the urban environment especial...

Excess heat in urban environments is an increasing threat to human health and well-being. Furthermore, the increasingly important phenomenon of the Urban Heat Island (UHI) is exacerbating problems of livability in urban centers. Hence, there should be an increasing effort to assess the impact of heat mitigation strategies (HMSs) on outdoor thermal...

This study analyses the interactions and impacts between multiple factors i.e., urban greening, building layout, and meteorological conditions that characterise the urban microclimate and thermal comfort in the urban environment. The focus was on two neighbourhoods of Lecce city (southern Italy) characterised through field campaigns and modelling s...
Chapter
This study investigates the effect of urban vegetation on thermal comfort in a neighbourhood of Lahti (Finland) by means of modeling simulations performed with the Computational Fluid Dynamics-based and microclimate model ENVI-met. A scenario without vegetation and the current one (with vegetation) are considered to assess the effects of vegetation...

The Apulian Region (Italy) is a socio-ecological system shaped by the millennial co-evolution between human actions and ecological processes. It is characterized by monumental olive groves protected from Regional Law 14/2007 for the cultural value of the landscape, currently threatened by the spread of a devastating phytopathogen, the bacteria Xyle...

This paper is devoted to the assessment of urban greening effects on two important ecosystem services, i.e., air quality and CO 2 storage, including the corresponding economic impacts in a real urban area, i.e., a district located in the Mediterranean city of Lecce (southern Italy). Two tools were employed, i-Tree Canopy and the computational fluid...

This paper presents a conceptual framework that looks at photovoltaic systems in synergy with ecosystem services. The focus is to connect business success with social and ecological progress based on the operative concept of multifunctional land use. Such an approach attempts to harmonise the needs of the industrial processes of photovoltaic system...

M.V.) † Equal contribution to this work. Abstract: This paper is devoted to the analysis of the impact of changes in olive urban forests affected by Xylella fastidiosa on ecosystem services. The focus is on microclimate and thermal comfort evaluated by two indices: the temperature of equivalent perception (TEP) and the predicted mean vote (PMV), wh...
Article
This paper discusses current state-of-the-art features of the “plant evaluation model”, a framework which, starting from the representation of vegetation and its effects in microclimate models, defines a number of indices which can be employed for the evaluation of outdoor microclimate in terms of thermal environment and comfort in the urban enviro...
Article
This study quantifies the influence of green spaces on microclimate and PM10 concentration in a typical residential district of Nanjing (China) by employing the CFD-based and microclimate model ENVI-met 4. Five green indices, related to quantity and structure of vegetation, are employed to investigate the impact of different types (grass, shrub and...

Dear Colleagues, we'd like to invite you to submit original research papers, as well as review articles, relating to “The Role of Urban Vegetation Management and Planning in Climate Change Adaptation Strategies" for the Special Issue of the journal Atmosphere where we are Guest Editors. Main topics include, but are not limited to: - urban vegetation responses to climate change; - effects of air temperature, air pollution and extreme weather events on urban vegetation and how this influences management and planning choices; - climate change adaptation strategies through vegetation assessed through a modelling approach and in situ observations and so on. I believe your contribution based on sound experience and achievements in urban green planning, biometeorology and urban forestry would make a valuable chapter in this Special Issue. For further information about this Special Issue, please see: https://www.mdpi.com/journal/atmosphere/special_issues/urban_vegetation_climate Deadline for manuscript submissions: 25 September 2021

My PhD research is focused on three big themes: Health, Sustainability and Urban planning. In particular, my activity is aimed at a) studying the impact of vegetation on thermal conditions and air quality in the urban environment and b) developing an IT tool that allows a smart urban planning of green spaces. My research is motivated by a keen interest to understand the complex inter-relations between several factors, specifically vegetation, meteorological conditions, urban geometry, and pollutants emission rates, which influence the livability in urban environment. My research is tailored to an accurate planning of urban vegetation, which considers different key parameters of vegetation (e.g. type, height, leaf area density (LAI)), meteorology (e.g. wind speed, wind direction, temperature) and urban morphology (e.g. aspect ratio H/W). In this perspective, the integration of three components is necessary: a) fluid dynamics analysis, b) urban planning and c) software development. a) Fluid dynamics analysis consists of simulations with high resolution CFD (Computational Fluid Dynamics) models. In particular, ENVI-met is employed. It's a prognostic, three-dimensional, grid based microclimate model, designed to simulate complex surface-vegetation-air interactions in the urban environment. The final aim is to develop simplified functional relations between those different key parameters to be implemented in a smart IT tool which will help urban planners in the choice of the most suitable plant species or the most appropriate vegetation arrangements.
