Outdoor Thermal Comfort Research and Its Implications for Landscape Architecture: A Systematic Review

Sustainability, Journal Year: 2025, Volume and Issue: 17(5), P. 2330 - 2330

Published: March 6, 2025

Amid global warming and urbanization, outdoor thermal comfort has become a critical consideration in landscape architecture. This study integrates systematic review bibliometric analysis of 1417 empirical studies (1980–2024) sourced from Web Science, aiming to clarify the current state research, identify core themes, propose future directions. examines key evaluation models, influence spatial morphology, their practical applications using keyword co-occurrence, citation networks, thematic analyses. Findings show significant rise research over past decade, particularly tropical subtropical regions. Core themes include indices (PMV, PET, UTCI), microclimate regulation, important indicators (height-to-width ratio, sky view factor, greening). The field is increasingly shifting towards simulation tools (such as ENVI-met CFD) rather than traditional measurements, with artificial intelligence emerging tool for predictive regulatory purposes, though its application remains limited. However, much focuses on small-scale morphological optimization lacks framework representation. Future should prioritize developing comprehensive system adaptable diverse landscapes, investigating interplay between form comfort, advancing sustainable, low-carbon design strategies. insights this provide solid foundation improving guiding sustainable urban development through

Experimental Analysis of Cool Roof Coatings as an Urban Heat Mitigation Strategy to Enhance Thermal Performance

Buildings, Journal Year: 2025, Volume and Issue: 15(5), P. 685 - 685

Published: Feb. 22, 2025

Driven by rapid urbanisation and global climate change, the increasing frequency intensity of Urban Heat Island effect poses significant risks to health well-being urban dwellers across world. To combat extreme heat ensure a safe level thermal comfort for residents, innovative sustainable technologies, such as green infrastructure cool roof coatings, have been incorporated into building design planning. This study aims evaluate compare effectiveness six different coating brands in reducing surface temperatures under harsh fast-changing conditions Melbourne, Australia. A pilot-sized experimental was installed on rooftop an existing office monitor temperature variations using infrared camera, accompanied statistical analysis potential reductions varying weather sky conditions. The results this show that application coatings reduced at least 8.7 °C up 34.2 °C, corresponding 13.2% 53.6% from maximum temperature, respectively. When comparing paint brands, it observed Brand 4 demonstrated best performance, minimum value 34.3 (45.5% reduction) when 62.9 °C. On other hand, 5 showed effective performance but still achieved reduction 15.8 (25.1% reduction). highlights mitigation strategy lowering temperatures. Alongside strategies, roofs walls, offer viable solution buildings.

Systematic Exploration of the Effect of Urban Green Space on Land Surface Temperature: A Scientometric Analysis

Buildings, Journal Year: 2025, Volume and Issue: 15(7), P. 1032 - 1032

Published: March 24, 2025

Urban green spaces (UGSs) are crucial for mitigating land surface temperature (LST) in the context of climate change and extremely high temperatures. Although numerous studies have explored impact UGSs on LST, a systematic understanding research scope, knowledge network structure, data sources, main methods, frontier trends this field is lacking. In study, 740 documents were retrieved from Web Science database, hotspots, trends, frontiers LST analyzed using scientometric analysis CiteSpace 6.2.R4 software. The results revealed that annual number publications citations has increased consistently, with rapid growth 2019 to 2024. However, communication dissemination findings hindered by lack efficient international collaboration networks academic institutions authors, highlighting need more vigorous global exchanges cooperation. Additionally, eight identified clusters extracted literature keywords, covering remote sensing, urban infrastructure, landscape patterns, spatial regression analysis, threshold values efficiency, etc., established specific content system, methodology. Furthermore, enhancing multi-disciplinary integration incorporating practical case will improve accuracy applicability facilitate translation theoretical into applications. This study provided comprehensive overview current offered valuable guidance studying thermal comfort sustainable development future.

Urban Microclimates in a Warming World: Land Surface Temperature (LST) Trends Across Ten Major Cities on Seven Continents

Urban Science, Journal Year: 2025, Volume and Issue: 9(4), P. 115 - 115

Published: April 5, 2025

Understanding microclimatic changes driven by urbanization is critical in the context of global warming and climate change. This study investigates land surface temperature (LST), normalized difference vegetation index (NDVI), use types for 10 major cities across seven continents between 2001 2021. Utilizing MODIS satellite data processed on Google Earth Engine (GEE) platform, analysis focused yearly median values to examine variations LST during day night, as well dynamics different types, including bare land. The mean trend from 2021, derived Terra MOD11A2 data, was found be 0.025 °C/year. daytime nighttime (nocturnal) (LST) trends ten examined this reveals notable variations, with most exhibiting an increasing within urban mosaics. Airports exhibited a that 2.5 °C higher than surrounding areas, while industrial zones demonstrated even greater disparity, average increase 2.81 °C. In contrast, cold spots characterized dense showed cooling effect, differences reaching −3.7 Similarly, proximity water bodies contributed mitigation, areas near significant sources recorded lower differences, averaging −4.09 A strong negative correlation NDVI LST, underscoring effect through evapotranspiration shading. provides comprehensive perspective commonalities diverse geographical regions climates, contributing deeper understanding how influence temperatures

Urban parks play a key role in mitigating heat stress and improving outdoor thermal comfort, especially tropical subtropical cities. This study evaluates comfort Nuevo Bosque Park (Montería, Colombia) through multiperspective approach that combines perception surveys (n = 99), situ microclimatic measurements, spatial mapping. Surface temperatures ranged from 32.0 °C the morning to 51.7 at midday sun-exposed areas, while vegetated zones remained up 10 cooler. Heat Index (HI) Temperature–Humidity (THI) values confirmed severe stress, with HI reaching 32 THI peaking 55.0 some zones. Subjective responses showed 69.69% of users reported discomfort, areas impermeable surfaces little shade. In contrast, 90.91% respondents stated tree cover improved their experience. The results indicate strong correlation between vegetation density, surface type, users’ perceived comfort. Additionally, urban furniture location natural ventilation emerged as factors influencing sensation. integration objective subjective data has enabled identification risk informed evidence-based recommendations for climate-adaptive park design. offers practical insights sustainable planning climates, demonstrating importance assessments consider both human environmental conditions enhance resilience usability public spaces.
