Assessing the influence of street canyon shape on aircraft noise
Results from measurements in courtyards near Amsterdam Schiphol Airport
Aircraft noise is a major stressor for communities in the vicinity of airports. Aircraft noise prediction models omit the built environment, based on an implicit assumption that the impact of buildings on the propagation of aircraft noise is neglectable. In this article a study i

This study aims to evaluate the impact of different urban building geometries (six courtyards, two canyons, two slabs) on heat mitigation and aircraft noise attenuation, in order to support an evidence-based retrofit plan for future airport neighborhoods. Using ’Pachyderm + ENVI-

Assessing the impact of building shape on aircraft noise attenuation
Comparison between geometrical acoustics simulation and in-situ measurements
Analyzing the impact of aircraft noise on urban areas requires specific consideration of sound propagation over long distances, which is not typically covered by tools designed for indoor acoustics. Although it is unclear to what extent existing parametric tools that combine 3D m

A scale model approach to simulate aircraft noise in street canyons
A comparison between in-situ and laboratory measurements
Aircraft noise is a major source of noise pollution in areas close to airports. Previous studies showed that the design of the urban and architectural context affects local sound levels. Due to surface reflections and edge diffraction, sound levels are reduced or amplified, depen

The dynamic thermal conditions profoundly impact on the quality of physical, cultural, and social experiences in courtyard spaces. This research aims to identify the microclimatic dissimilarities between courtyards in terms of tempering seasonal–diurnal thermal extremes and enric

Urban climate walk
A stop-and-go assessment of the dynamic thermal sensation and perception in two waterfront districts in Rome, Italy
This study set out to understand the dynamics of human thermal sensation and perception associated with outdoor thermal variability in urban contexts. Previous studies found that compact urban forms and green features can contribute to urban climate diversity, and conjectured whe

The effects of urban morphology on enriching thermal experience
Microclimates of courtyard spaces in Cambridge
The microclimate shaped by urban form is one of the critical determinants for the success of public spaces. To date, hundreds of studies have revealed the potential of mitigating heat and cold stresses by spatial-enclosure strategies to reduce thermal discomfort. However, most of

Crowdsourced weather data has been increasingly used to provide the input data for the boundary conditions in the microclimate models as well as to validate the modelling outputs. MeteoTracker (MT) is an Internet of Things (IoT) application for domestic vehicles that can contribu

Assessing Comfort in Urban Public Spaces
A Structural Equation Model Involving Environmental Attitude and Perception
The research of comfort in urban public spaces has become increasingly important for improving environmental quality and encouraging people spend more time in outdoor activities. Among numerous approaches to understand comfort perception, the rational indices based on heat balanc

This study addresses students’ perceptions of using urban green spaces (UGSs) after the easing of COVID-19 lockdown in China. We questioned whether they are still mindful of the risks from the outdoor gathering, or conversely, starting to learn the restoration benefits from the g

Urban microclimatic diversity and thermal comfort
Do variations in sun and wind conditions correlate with PET grades?
Urban microclimatic diversity is of significance to understanding outdoor thermal satisfaction, as it offers a degree of freedom of choice for comfort seeking behaviour, thermal stimulation and potential alliesthesia. The existing assessment of thermal diversity has shown a stron
