Thermal benefits of vertical greening in a high-density city: Case study of Hong Kong
TL;DR: In this paper, a parametric study was conducted to investigate the quantity and location of facade greening required for potential air cooling and thermal comfort improvement of a neighborhood of varying densities, which revealed an acceptable modelling of facade surface temperature, air temperature, relative humidity and wall-emitted long-wave fluxes.

LES case study on pedestrian level ventilation in two neighbourhoods in Hong Kong
TL;DR: In this paper, a case study of pedestrian level ventilation in two neighbourhoods in Kowloon, downtown Hong Kong using the parallelized large-eddy-simulation (LES) model PALM is presented.

Observational studies of mean radiant temperature across different outdoor spaces under shaded conditions in densely built environment
Alan Lai,Minjung Maing,Edward Ng +2 more
TL;DR: In this article, the relationship between sky view factor (SVF) and MRT in built environment is examined. But, it is believed that overly restricted Sky View Factor limits the radiative cooling by the sky of lower effective temperature.

Relationship between pedestrian-level outdoor thermal comfort and building morphology in a high-density city
TL;DR: The objective was to quantify the thermal environment and OTC in different planned complex urban forms by well-validated numerical models and produced sensible street-level physiologically equivalent temperatures (PETs) when comparing with those listed in the human thermal sensation categories.

Reduced effectiveness of tree planting on micro-climate cooling due to ozone pollution—A modeling study
TL;DR: In this paper, the effects of ambient ozone on the leaf area index (LAI) of trees and the resultant reduction in the effectiveness of trees in providing micro-climate cooling in megacities were studied.
