Heat exposure and cooling efficiency of trees in a tropical hot-humid neighborhood with a park
As cities increasingly endure hotter conditions, there is a critical need for reliable metrics that capture the cumulative and perceptual nature of pedestrian heat exposure. This study develops an integrated approach combining high-resolution urban Computational Fluid Dynmics (CFD) simulations with two complementary indices: a cumulative Heat Exposure Index and a Cooling Efficiency Index that quantify the magnitude, duration, and spatial variabil…
Global warming likely compromises the annual performance of zero-energy buildings while the urban heat island effect exacerbates the impact
Cooling efficacy of trees across cities is determined by background climate, urban morphology, and tree trait
Urban planners and other stakeholders often view trees as the ultimate panacea for mitigating urban heat stress; however, their cooling efficacy varies globally and is influenced by three primary factors: tree traits, urban morphology, and climate conditions. This study analyzes 182 studies on the cooling effects of urban trees across 17 climates in 110 global cities or regions. Tree implementation reduces peak monthly temperatures to below 26 °C…
Urban morphology clustering analysis to identify heat-prone neighbourhoods in cities
Exposure to heat is a major health concern to urban populations. Cities aim to reduce outdoor thermal stress by adapting the built environment, but the spatial heterogeneity within cities makes it difficult to establish universal mitigation strategies. We present a methodology that identifies the hottest neighbourhoods in a city and links them to underlying patterns in urban form and function, to derive heat mitigation measures for individual nei…
Optimal representation of tree foliage for local urban climate modeling
Starting with terrestrial LiDAR data from trees of different species, ages, and forms, we propose a systematic evaluation of the optimal representation of arboreal configurations in terms of local urban comfort. • Comparing four species and three maturity level of trees with this method, the paper shows that the size of the zone shadowed by a tree is the parameter with the largest impact on thermal comfort, as the ability of trees to absorb solar…
A WRF-UCM-Solweig framework for mapping thermal comfort and quantifying urban climate drivers: Advancing spatial and temporal resolutions at city scale
Highly inhomogeneous interactions between background climate and urban warming across typical local climate zones in heatwave and non-heatwave days
Urban heat island (UHI) in conjunction with heatwave (HW) leads to exacerbation of thermal stress in urban areas. Prior research on UHI and HW has predominantly concentrated on examining the thermal conditions at the surface and near-surface, with few investigations extending to the radiative and dynamical interactions of UHI and HW, particularly with a focus on the inhomogeneities across local climate zones (LCZs). Here, we analyse the temperatu…
Using clustering to understand intra-city warming in heatwaves: Insights into Paris, Montreal, and Zurich
We introduce a novel methodological advancement by clustering paired near-surface air temperature with the planetary boundary layer height to characterize intra-city clusters for analytics. To illustrate this approach, we analyze three heatwaves (HWs): the 2019 HW in Paris, the 2018 HW in Montreal, and the 2017 HW in Zurich. We assess cluster-based characteristics before, during, and after heatwave events. While the urban clusters identified by t…
Relating three-decade surge in space cooling demand to urban warming
Rising demand for space cooling has been placing enormous strain on various technological, environmental, and societal dimensions, resulting in issues related to energy consumption, environmental sustainability, health and well-being, affordability, and equity. Holistic approaches that combine energy efficiency optimization, policy-making, and societal adaptation must be rapidly promoted as viable and timely solutions. We interpret the 30 year cl…
