Abstract: Need for natural ventilations are increasing because of demanding per capita energy consumption. Major challenges in natural ventilation are sufficient wind velocity throughout and providing cross ventilation building structure. Especially in urban area, possibility to provide cross ventilation is not possible as population factor is challenging. This lays emphasis on the significance of inducing natural ventilation in the buildings of urban areas to reduce energy consumption for human comfort. To visualize the performance of air ventilation of proposed models, simulation has been carried out using CFD. Proposal includes the new design in a residential room of urban building, which is having multiple opening with convergent and divergent nozzle structures in the pattern of window described below. For the boundary condition of CFD simulation, field study data were used. This paper investigates four different window patterns and is analyzed for better performance. In each pattern it has neutral axis horizontally and the structure used above are convergent type and bottom row are divergent type when it looks from inside of the buildings.
