Green infrastructure plays a fundamental role in mitigating the effects of urban heat island. Vegetation may trap particulates and absorb pollutants like ozone, thus improving air quality. Understanding how green reduces island pollution within specific zones can provide valuable insights for better design, improved environmental quality, increased resident well-being. This study addresses impact deprivation on effects, pollution, heat-related health risks Porto, Portugal. The employs monitoring network to analyse spatial distribution temperature humidity throughout city, although with gaps coverage. With focus this paper uses data from Porto Digital's between 2019 2022.

Scenario analysis of supply‐ and demand‐side solutions for circular economy and climate change mitigation in the global building sector

Journal of Industrial Ecology, Journal Year: 2024, Volume and Issue: 28(6), P. 1699 - 1715

Abstract Residential and non‐residential buildings are a major contributor to human well‐being. At the same time, cause 30% of final energy use, 18% greenhouse gas emissions (GHGE), about 65% material accumulation globally. With electrification higher efficiency buildings, material‐related gain relevance. The circular economy (CE) strategies, narrow, slow, close , together with wooden can reduce emissions. We provide comprehensive set building stock transformation scenarios for 10 world regions until 2060, using resource climate change model stock–flow–service nexus including full CE spectrum plus wood‐intensive buildings. 2020–2050 global cumulative new construction ranges from 150 280 billion m 2 residential 70‐120 Ambitious reduces primary demand 80 30 gigatons (Gt) cement 35 15 Gt steel.

Influence of objective and perceived exposures to urban nature on people’s happiness

Published: May 13, 2025

Exposure to nature influences urban dwellers’ well-being and happiness, thereby impacting sustainability. However, dwellers are exposed in different ways: indirect exposure through window views, incidental when walking along streets, intentional visiting parks. Moreover, objective does not necessarily align with how people perceive their nature. This study examines three types of exposure—indirect, incidental, intentional—provided by greenery water bodies, perceived exposure, impact happiness Tokyo, Japan. To measure the we use 3D photorealistic city information models, street view imagery, road network datasets, remote sensing imagery. data from a national survey, focusing on results 10,798 residents 801 neighborhoods Tokyo. Results showed that has higher explanatory power for than exposure. Views windows (indirect exposure) proximity parks (intentional influenced most.

Research on Summer Hourly Climate-Influencing Factors in Suburban Areas of Cities in CFA Zone—Taking Chengdu, China as an Example

Buildings, Journal Year: 2024, Volume and Issue: 14(10), P. 3083 - 3083

Published: Sept. 26, 2024

Elevated temperatures in urban centers have become a common problem cities around the world. However, climate problems suburban areas are equally severe; there is an urgent need to find zero-carbon ways mitigate this problem. Recent studies revealed thermal performance of vegetation, buildings, and water surfaces. They functioned differently regarding at different periods day. Accordingly, study synthesizes remote sensing technology meteorology station observation data deeply explore differences role each climate-influencing factor Chengdu. The land surface temperature (LST) air (Ta) were used as environmental indicators, while normalized difference vegetation index (NDVI), (NDWI), built-up (NDBI), altitude factors. results showed that relevant influences factors on sample significantly affected by time NDVI (R2 = 0.5884), NDBI 0.3012), 0.5638) all strong correlations with Ta during night (20:00–7:00), which gradually weakened after sunrise, yet NDWI poorer cooling effect night, strengthened reaching maximum 15:00 0.5012). One reason for phenomenon was daily weather changes. These findings facilitate advancement understanding provide clear directions further services targeted towards people areas.

Published: Feb. 2, 2025

Abundant and diverse urban bird communities promote ecosystem human health in cities. However, the estimation of community structure requires large amounts resources. On other hand, calculating remotely sensed spectral indices is cheap easy. Such are directly related to vegetation cover, built-up temperature, factors that also affect presence abundance species areas. Therefore, can be used as proxies communities. We estimated abundance, taxonomic, functional, phylogenetic diversity at each 18 50 m radius survey stations core area Kavala, Greece. calculated eight (means standard deviations, SDs) around m, 200 500 spatial scales. The land surface temperature SD (LST) was most important proxy, positively At same time, mean green normalized difference index (GNDVI) negatively scale. Means SDs indices, such (NDVI), enhanced (EVI2), soil-adjusted (SAVI), atmospherically resistant (ARVI), were proxies, taxonomic functional all LST, moisture (NDMI), (NDBI) variously affected diversity. LST best scales, while NDBI NDMI results suggest several reliable various facets Using an easy efficient way informing successful planning management.
