Abstract

The aim of this paper is to investigate the effect of urban geometry on microclimate through a case study of the Greater London area. GIS data are used to describe the urban characteristics and calculate both spatial average and heterogeneity variables. Computational Fluid Dynamics (CFD) simulations are performed in areas of London in order to obtain their microclimatic conditions. The CFD simulations are performed using the standard k-e turbulence model and Reynolds-Averaged Navier Stokes (RANS) equations. Next, correlation analyses using the Spearman's rank correlation coefficient are carried out to determine the impact of the urban variables on microclimate. The case study demonstrates that average urban density and building geometry have a substantial effect on microclimate. Furthermore, variation in building geometry and canyon ratio also have a significant impact. It is thus concluded that both average spatial variables and spatial heterogeneity should be included in urban climate studies.
