3D simulation of urban microclimate using ENVI-Met / Norina Omar

One is the environmental impact of rapid urbanization is the Urban Heat Island (UHI). This climatic phenomenon can directly affect urban dwelling discomfort and indirectly related to climate change due to their contribution to the greenhouse effect and hence leads to global wanning.

This climatic phenomenon can directly affect urban dwelling discomfort and indirectly related to climate change due to their contribution to the greenhouse effect and hence leads to global wanning. This research aims to study the effects of built and natural environment on the air temperature distribution within a small urban setting.
