This contribution introduces an airflow zonal model (AZM) for block-scale urban environments, designed to assess key climatic variables involved in heat stress wind-driven configurations. The relies on prior steady CFD calculations using the RANS realizable k−ϵ turbulence and linear interpolation predict average mass flow rates, wind speeds, convective transfer coefficients, pressure coefficients. Dynamic energy balances are solved each airzone. validity of setting is established by comparing simulation results with experimental data isolated cube. A case study a building block illustrates AZM's ability replicate patterns consistent CFD, emphasizing impact geometry thermal properties spatial temporal distribution air temperature, velocity, mean radiant temperature. AZM offers computationally efficient alternative enabling simulations over seasonal timescales.
