Natural-anthropogenic environment interactively causes the surface urban heat island intensity variations in global climate zones

Environment International, Journal Year: 2022, Volume and Issue: 170, P. 107574 - 107574

The inconstant climate change and rapid urbanization substantially disturb the global thermal balance induce severe urban heat island (UHI) effect, adversely impacting human development health. Existing literature has revealed UHI characteristics driving factors at an scale, but interactions between main of a grid scale assessment on context zones remain unclear. Therefore, based multidimensional climatic socio-economic statistical datasets, multi-time surface intensity (SUHI) was investigated in this study to analyze how natural-anthropogenic drivers affect variance SUHI vary their importance for changes other interaction factors. results show that mean value summer is higher than winter, daytime nighttime seasonal daily scale. SUHIs different have significant differences. When analyzing drivers' contributions with LightGBM model SHAP algorithm, we know monthly precipitation (PREC), estimated population (POP) pressure (PRES) are three major SUHI. mainly PREC, POP anthropogenic emission (AHE), influence rules natural driversare mostly opposite daytime. This highlights fundamental role background designing strategies. Irrigation or artificial rainfall will be effective mitigate low areas, while it more reduce AHE high areas. In where greening can difficult most developed cities, reducing AHE, increasing per capita GDP controlling may also contribute alleviating provides ideas developing responsive mitigation policies realistic setting.

Contrasting determinants of land surface temperature in three megacities: Implications to cool tropical metropolitan regions

Sustainable Cities and Society, Journal Year: 2023, Volume and Issue: 92, P. 104505 - 104505

Published: March 5, 2023

Megacities in tropical regions are among the urban centers most vulnerable to increasingly intense heatwaves. However, complex interactions between characteristics and thermal environments yet be fully understood. Here, we investigated relationship land surface temperature (LST) for three megacities savannah climate zone, Chennai, Dhaka, Kolkata. LST values were retrieved from Landsat 8 data, features constructed using digital models, building footprints, satellite imagery. Model-agnostic approaches adopted analyze impacts of on LST. The boosted regression tree (BRT) model was used capture nonlinear effects six important factors changes. dominant influencing normalized difference built-up index, albedo, vegetation index. Building roofs, roads, other hardscapes with high-albedo materials preferred alleviating heat island effect Dhaka placement parks woody an area larger than 0.6 ha produced effective cooling effect. In Chennai Kolkata, policies increase sky view factor recommended. application BRT integrated data provides unique insights resilience planning.

Impediments in BIM implementation for the risk management of tall buildings

Results in Engineering, Journal Year: 2023, Volume and Issue: 20, P. 101401 - 101401

Published: Sept. 5, 2023

This study background highlights the increasing need for effective management of risks in tall buildings due to their complexity and potential hazards. BIM has been accepted as a solution buildings; however, its adaptation slow several obstacles. The purpose this is identify validate impediments risks. adopted two-step methodology, consisting exploratory factor analysis (EFA) structural equation modelling (SEM). data were collected through an online survey professionals involved design, construction, management. Results reveal six significant impediments: technical, integration, operational, creativity, privacy, standardization. findings provide theoretical contributions literature by identifying validating buildings. Practical implications suggest that organizations address identified ensure successful contributes understanding obstacles provides insights overcome these impediments.
