“…Most urban areas are considered the centers of heat generation and are commonly called "urban heat islands" [93] They largely depend on solar insolation, wind speed, cloud cover, humidity, vegetation coverage, construction materials, etc. [94], [95]. Urban heat islands consume vast amounts of cooling energy during the summer season [96].…”

“…Urban heat islands consume vast amounts of cooling energy during the summer season [96]. Sufficient green space in urban areas reduces air temperature on both the horizontal [97] and vertical [96] scales, as well as cooling energy requirements within the urban area and its periphery [17], [94]- [97]. Some scholars explain green spaces as the "natural air conditioner" that can reduce building energy [98], [99] and create barriers to release carbon dioxide, nitrogen dioxide, and ozone gases into the air [100].…”

In this research, the connection between land use and energy has been discussed from two points of view, i.e., the impacts of energy on land use and the impacts of land use on energy. This research identified several direct and indirect land use changes that occur by clearing vegetation, destroying top soils, and relocating human populations during the different stages of extraction, deposition, and transportation of fossil fuels and uranium ore; and during the establishment of renewable energy sources including wind turbines, hydro-power plants, and associated structures (highways, dams, culverts, tunnels, power station infrastructure, and energy transmission networks). Likewise, feedstock cultivation, processing, and transportation to biomass plants, as well as the production of biodiesel from municipal solid waste, require accessible land resources that further contribute to global land-use change. In the case of the impacts of land use on energy, mixed use development was found to be one of the most efficient approaches to achieve energy efficiency. Similarly, energy demand for motorized travel can also be reduced with the development of urban blocks and transit-oriented development. Furthermore, integrated combined heat and power systems, green space, and energy-supporting land use regulations were identified as energy savings strategies that may aid in achieving energy efficiency and ensuring sustainable development.

“…En el mismo trabajo de García-Nevado, Pages-Ramon y Coch, se ha podido calcular el análisis de las principales variables que influyen en el acceso al sol utilizando análisis estadísticos (Arboit, Diblasi, Fernández Llano, y de Rosa, 2008). Además, se ha monitoreado in situ la irradiancia solar en fachadas norte (W/m2), calculando el enmascaramiento sólido y el enmascaramiento del arbolado y se han establecido coeficientes de sombra e irradiación para las distintas configuraciones morfológicas urbano-edilicias (Arboit y Betman, 2016;Arboit y Betman, 2017). Las variables morfológicas de las configuraciones urbanas y edilicias tienen una incidencia fundamental en la factibilidad técnica de implementar estrategias de aprovechamiento de la energía solar en medios urbanos.…”

El estudio realiza un análisis del ancho de calles en el Área Metropolitana de Mendoza (AMM) y sus seis departamentos, como parte de la problemática del desarrollo ambiental y energéticamente sostenible del sector edilicio en ciudades de la región árida del centro-oeste de Argentina. La morfología urbano-edilicia está en estrecha relación con las condiciones energéticas y el confort urbano, por lo que el conocimiento de las características del trazado urbano y la disponibilidad de datos para evaluar las posibilidades de implementar estrategias en procesos de densificación, renovación, rehabilitación y diseño de zonas urbanas es de gran utilidad para la planificación energéticamente más eficiente en ciudades con crecimiento de población y expansión urbana. Metodológicamente se cuantificó la variable urbana ancho de calle y se categorizó a las manzanas urbanas en función de dicha variable para el AMM en sistemas de información geográfica (SIG). Se analizaron estadísticamente los resultados para las manzanas urbanas y se construyeron gráficos de densidades a partir de las categorías definidas. La evaluación indica, un valor medio de ancho de calles de 19,07m. Las conclusiones del estudio espacial evidencian que es posible elaborar estrategias energéticas basadas en los anchos de calle existentes, identificando prioridades por departamentos.

“…Two modeling tools are used, the software i-Tree Canopy and the computational fluid dynamics (CFD)-based microclimate model ENVI-met. i-Tree Canopy was recently applied in the scientific literature to quantify green cover and its economic benefits [25][26][27][28][29][30][31][32][33], while there are no studies applying such a tool in Lecce. ENVI-met was successfully employed in studies analyzing the effects of vegetation on microclimate and thermal comfort in the urban environment, where it was thoroughly described [34][35][36][37][38][39][40]; it was also employed for an investigation of air quality, focusing on air pollutant deposition and dispersion in several studies [41][42][43][44][45][46][47][48][49], which mostly found a satisfactory agreement with observations and concluded that, although it is not a very sophisticated model, it provides sufficient functions for establishing small-scale pollutant distribution for studies of urban greening in near-road environments.…”

Characterization of Urban Greening in a District of Lecce (Southern Italy) for the Analysis of CO2 Storage and Air Pollutant Dispersion

et al. 2020

This paper is devoted to the assessment of urban greening effects on two important ecosystem services, i.e., air quality and CO2 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 dynamics (CFD) microclimate model ENVI-met. i-Tree Canopy allowed fully determining the land-cover percentage on the basis of different ground cover classes and obtaining an estimate of annual values of CO2 storage, air pollutant removal, and economic benefits in the presence of urban greening. The estimate in i-Tree Canopy considered only the amount of greening; therefore, air pollutant removal estimates were only potential. As the vegetation was located in street canyons, its interaction with local meteorology and urban geometry strictly affected the dispersion of nitrogen oxides (NOx) (taken here as an example) as obtained from ENVI-met simulations. In ENVI-met, both deposition/absorption and aerodynamic effects were considered, and local increases in concentration were found in the district. The analysis of results obtained from different tools (one complex (CFD model) and the other simple (i-Tree model)) showed the error associated with the simple model in the computation of impacts if the interaction among the vegetation characteristics, the meteorological conditions, and the urban geometry was neglected; however, it also uncovers a novel approach for comprehensively characterizing a given area in terms of its vegetation cover, CO2 storage, and economic benefits, as well as local effects on air quality. This study is set in a broader context aimed at assessing the air quality in urban canopies of Mediterranean areas characterized by the presence of narrow street canyons where pollutants can accumulate due to ineffective air exchange with the above atmosphere.
