“…Organizations and agencies such as the Landscape Architecture Foundation, World Green Infrastructure Network, the U.S. Green Building Councils, and the U.S. Environmental Protection Agency emphasize the strengths of GR in regulating microclimates and improving urban sustainability [9][10][11][12]. Due to the plant covering, GR can minimize solar radiation absorption, retention, and transmission [13][14][15][16][17][18]. GR lessens the thermal burden of the rooms located below in the summer as well as the wintertime heat loss via the roof [19].…”

This study explores and quantifies the impacts of green roofs (GR) design factors on microclimate regulation. Against rapid urbanization and intensifying climate changes, green infrastructure has received increasing attention due to its contribution to dealing with the urban heat islands effect (UHIE) and increasing urban sustainability. GR is one example of green infrastructure and is widely used in cities. However, its microclimate regulation benefits have not been thoroughly explored and require more exploration. There are insufficient studies on quantifying GR design factors impacts on microclimate regulation. Meanwhile, little research has explored the impact of regulating microclimate when accessibility is considered as a design factor. Using a GR in Washington, D.C., as a case study, this study models 14 roof scenarios with several common GR design factors, generates their simulated microclimate patterns, and quantifies each design factors impact based on statistical analyses. Results present quantitative data on how studied design factors change microclimate patterns and find that accessibility does affect some microclimate aspects but only to a limited rate. This study provides suggestions and insights to optimize GR design guidelines. Overall, this study contributes to the refinement of GR research, promotes better GR design, and responds to urbanization and climate issues.

“…The LST value retrieval from satellite imagery can highlight that the major contribution to lessening and moderating the impact of heat waves is mainly associated with urban green infrastructure (UGI) assets, such as urban forests, parks, water bodies, leisure spaces with impervious surfaces, or smaller green spaces (i.e., green roofs or pocket parks) [33][34][35][36][37]. The assessment of those UGI areas in terms of greenness or any other type of land cover can be efficiently carried out with the normalized difference vegetation index (NDVI).…”

Heat wave episodes are becoming more frequent and severe worldwide, especially in areas such as the Mediterranean region. This study is aimed at assessing the impact of heat waves in an urban environment and the ways areas of urban green infrastructure (UGI) can play key roles in moderating the impacts of these high-temperature events. We analyzed land surface temperature (LST) and normalized difference vegetation index (NDVI) data retrieved from Landsat 8/9 satellite images. These data were recorded during heat wave episodes from 2017 to 2022 in a representative Mediterranean medium-sized compact city. We carried out a correlation analysis between LST and NDVI per area type and as individual units to assess how UGI elements can contribute to the cooling of the urban matrix during heat wave episodes. Those small green spaces distributed throughout the city, defined as “Other” areas, showed stronger negative correlation. These spaces are particularly relevant for Mediterranean cities, where highly limited space in city centers hinders the possibility of having larger-surface UGI elements. The study highlights the need for further research into the composition of those small public green spaces to understand how their components enhance the city’s cooling capacity given the climate conditions and water scarcity in the Mediterranean region.

“…Different GI types play multiple functions in mitigating UHIs, serving to lower land surface temperatures and easing the urban thermal environment by increasing cooling, such as increasing shaded areas from tree canopies and the evaporation of various types of vegetation; improving the surface energy balance, as by increasing the absorption and reflection of solar radiation from trees or different types of vegetation; and affecting air movements and heat exchange, as by covering areas with vegetation to retain water for evaporation and to quickly absorb and retain heat when exposed to solar radiation [20][21][22][23][24][25]. Additionally, GI can reduce air pollution, carbon emissions and carbon sequestration, stormwater runoff, heat-stress-associated mortality, and illness, and is thus beneficial for human health, the ecological environment, and sustainability development [26][27][28].…”

Climate change and rapid urbanization increase/amplify urban heat islands (UHIs). Green infrastructure (GI) is an effective and popularly strategy used to moderate UHIs. This paper aims to better understand the progress of different GI types (urban parks, urban forests, street trees, green roofs, green walls) in mitigating UHIs, and what benefits they provide. Firstly, this paper used CiteSpace to analyze 1243 publications on the Web of Science from 1990 to 2021, then analyzed the function/regulation of ecosystem services/benefits and values of GI types in reducing UHIs. The historical review results show that research on all GI types showed rapid growth since 2013, and their GR increased rapidly. The highest-ranking keywords were urban heat island/heat island, climate/climate change/microclimate, and temperature/land surface temperature/air temperature. “Design,” “vegetation,” “quality,” and “reduction” are the top four strongest keyword bursts. The most published countries are the People’s Republic of China, USA, Australia, Germany, and Italy, and the top three institutions are the Chinese Academy of Sciences, Arizona State University, and the National University of Singapore. Landscape and Urban Planning, Building and Environment, Energy and Building, and Urban Forestry and Urban Greening are the most published journals. In urban areas, different GI types as a form of ecosystem hardware provide multiple functions (reduced land surface temperatures, lower building energy usage, improved thermal comfort and enhanced human health, reduced morbidity and mortality, etc.). GI thus provides a regulated ecosystem service to ameliorate UHIs primarily through temperature regulation and shade. At the same time, GI provides benefits and values (ecological, economic, social, and cultural) to humans and urban sustainable development. GI types determine the functions they provide, afford corresponding regulated ecosystem services, and provide benefits and values in a logical/recycle system. Overall, this review highlights the development and importance of GI, as well as the relationship of GI types and functions of regulating the ecosystem service benefits and values to mitigate UHI, and advances the study of climate change adaptation in cities.
