Abstract
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-met simulations + field measurements’, we found that the slanted-roof, low-rise courtyard exhibited optimal acoustic-thermal performance (SPLmin = 71.1 dB(A), σU T CI < 5 ◦C), while the mid-rise canyon demonstrated limited performance (SPLmin = 93.4 dB(A), σU T CI > 10 ◦C). These findings were observed under averaged boundary conditions of a 140 dB(A) aircraft sound source and a diurnal MRT range of 60 ◦C on a heatwave day in July 2022.
