Urban heat mitigation through misting, and its role in broader blue infrastructure portfolios
Urbanization-induced disparity of extreme heat distribution in metropolitan Beijing
Dynamic changes of urban street thermal environment from the pedestrian perspective and their impacts on pedestrians' walking behaviors
Observed determinants of urban outdoor thermal exposure during hot summer and snowy winter periods in a humid continental climate
Mobile biometeorological station MaRTy used for data collection in Guelph, Canada • Mean radiant temperature determined from 6-direction shortwave and longwave radiation • Shade strongly reduces daytime heat exposure but slightly increases it at night • Snow cover in winter generates solar reflection warming and longwave cooling at night • Recommendations for street design and maintenance for both hot and cold weather Many cities in the midlatitu…
WebMRT: An online tool to predict summertime mean radiant temperature using machine learning
The effects of 2-D and 3-D urban landscape metrics on mean radiant temperature in hot-arid Phoenix and Tempe, Arizona, USA
Maximizing the pedestrian radiative cooling benefit per street tree
Outdoor heat stress is a growing problem in cities during hot weather. City planners and designers require more pedestrian-centered approaches to understand sidewalk microclimates. Radiation loading, as quantified by mean radiant temperature (TMRT), is a key factor driving poor thermal comfort. Street trees provide shade and consequently reduce pedestrian TMRT. However, placement of trees to optimize the cooling they provide is not yet well under…

Impact of 3-D urban landscape patterns on the outdoor thermal environment: A modelling study with Solweig
How are cities planning for heat? Analysis of United States municipal plans
Heat has become a central concern for cities everywhere, but heat governance has historically lagged behind other climate change hazards. This study examines 175 municipal plans from the 50 most populous cities in the United States to understand which aspects of urban heat are included or not in city plans and what factors explain inclusion. We find that a majority of plans mention heat, but few include strategies to address it and even fewer cit…
Training Computers to See the Built Environment Related to Physical Activity: Detection of Microscale Walkability Features Using Computer Vision
The study purpose was to train and validate a deep learning approach to detect microscale streetscape features related to pedestrian physical activity. This work innovates by combining computer vision techniques with Google Street View (GSV) images to overcome impediments to conducting audits (e.g., time, safety, and expert labor cost). The EfficientNETB5 architecture was used to build deep learning models for eight microscale features guided by …
Outdoor thermal performance of green roofs across multiple time scales: A case study in subtropical China
Cooling hot cities: A systematic and critical review of the numerical modelling literature
Infrastructure-based heat reduction strategies can help cities adapt to high temperatures, but simulations of their cooling potential yield widely varying predictions. We systematically review 146 studies from 1987 to 2017 that conduct physically based numerical modelling of urban air temperature reduction resulting from green-blue infrastructure and reflective materials. Studies are grouped into two modelling scales: neighbourhood scale, buildin…
The co-production of sustainable future scenarios
Scenarios are a tool to develop plausible, coherent visions about the future and to foster anticipatory knowledge. We present the Sustainable Future Scenarios (SFS) framework and demonstrate its application through the Central Arizona-Phoenix Long-term Ecological Research (CAP LTER) urban site. The SFS approach emphasizes the co-development of positive and long-term alternative future visions. Through a collaboration of practitioner and academic …
Impacts of form and design policies on urban microclimate: Assessment of zoning and design guideline choices in urban redevelopment projects
Solar reflective pavements—A policy panacea to heat mitigation
Cities worldwide are piloting the use of solar reflective coatings on roads to mitigate the Urban Heat Island (UHI). Solar reflective pavement has been praised as simple, low-cost solution with a demonstrated ability to reduce surface temperature. Less well understood is the effect of solar reflective coatings on radiant heat, which influences human thermal exposure and comfort. We present the first biometeorological observations of solar reflect…
Thermally resilient communities: Creating a socio-technical collaborative response to extreme temperatures
Extreme temperatures claim more lives than any other weather-related event, posing escalating socio-technical and governance challenges that few urban communities have addressed in a systematic, coordinated and comprehensive way. Scholars have only recently begun to investigate the granular scales at which distributions of thermal risk are produced, people’s individual subjective thermal experiences and environmental justice dimensions of the haz…
Urban form and composition of street canyons: A human-centric big data and deep learning approach
Various research applications require detailed metrics to describe the form and composition of cities at fine scales, but the parameter computation remains a challenge due to limited data availability, quality, and processing capabilities. We developed an innovative big data approach to derive street-level morphology and urban feature composition as experienced by a pedestrian from Google Street View (GSV) imagery. We employed a scalable deep lea…
Heat exposure during outdoor activities in the US varies significantly by city, demography, and activity
Quality of Crowdsourced Data on Urban Morphology—The Human Influence Experiment (Huminex)
The World Urban Database and Access Portal Tools (WUDAPT) is a community initiative to collect worldwide data on urban form (i.e., morphology, materials) and function (i.e., use and metabolism). This is achieved through crowdsourcing, which we define here as the collection of data by a bounded crowd, composed of students. In this process, training data for the classification of urban structures into Local Climate Zones (LCZ) are obtained, which a…
Impact of shade on outdoor thermal comfort—a seasonal field study in Tempe, Arizona
Shade plays an important role in designing pedestrian-friendly outdoor spaces in hot desert cities. This study investigates the impact of photovoltaic canopy shade and tree shade on thermal comfort through meteorological observations and field surveys at a pedestrian mall on Arizona State University's Tempe campus. During the course of 1 year, on selected clear calm days representative of each season, we conducted hourly meteorological transects …
Urban forestry and cool roofs: Assessment of heat mitigation strategies in Phoenix residential neighborhoods
The City of Phoenix (Arizona, USA) developed a Tree and Shade Master Plan and a Cool Roofs initiative to ameliorate extreme heat during the summer months in their arid city. This study investigates the impact of the City's heat mitigation strategies on daytime microclimate for a pre-monsoon summer day under current climate conditions and two climate change scenarios. We assessed the cooling effect of trees and cool roofs in a Phoenix residential …
Impact of urban form and design on mid-afternoon microclimate in Phoenix Local Climate Zones
This study investigates the impact of urban form and landscaping type on the mid-afternoon microclimate in semi-arid Phoenix, Arizona. The goal is to find effective urban form and design strategies to ameliorate temperatures during the summer months. We simulated near-ground air temperatures for typical residential neighborhoods in Phoenix using the three-dimensional microclimate model ENVI-met. The model was validated using weather observations …
Tradeoffs Between Water Conservation and Temperature Amelioration In Phoenix and Portland: Implications For Urban Sustainability
This study addresses a classic sustainability challenge—the tradeoff between water conservation and temperature amelioration in rapidly growing cities, using Phoenix, Arizona and Portland, Oregon as case studies. An urban energy balance model— LUMPS (Local-Scale Urban Meteorological Parameterization Scheme)—is used to represent the tradeoff between outdoor water use and nighttime cooling during hot, dry summer months. Tradeoffs were characterized…
