     techniques for modelling urban microclimates and urban block surfaces temperatures are desired by urban planners and architects for strategic urban designs at the early design stages. this paper introduces a simplified mathematical model for urban simulations (umsim) including urban surfaces temperatures and microclimates. the nodal network model has been developed by integrating coupled thermal and airflow model. direct solar radiation, diffuse radiation, reflected radiation, long-wave radiation, heat convection in air and heat transfer in the exterior walls and ground within the complex have been taken into account. the relevant equations have been solved using the finite difference method under the matlab platform. comparisons have been conducted between the data produced from the simulation and that from an urban experimental study carried out in a real architectural complex on the campus of chongqing university, china in july 2005 and january 2006. the results show a satisfactory agreement between the two sets of data. the umsim can be used to simulate the microclimates, in particular the surface temperatures of urban blocks, therefore it can be used to assess the impact of urban surfaces properties on urban microclimates. the umsim will be able to produce robust data and images of urban environments for sustainable urban design.
