Abstract This paper presents the results of the experimental investigations carried out on two intricate plan-shaped buildings to evaluate the aerodynamic performance of the building. The intention is to explore the associated environment resulting from wind forces in both solitary and obstructing situations using a prototype model at a scale of 1:300 with a prototype having 180m height. Experimental tests were carried out at the boundary layer wind tunnel considering isolated conditions with 0° to 180° isolated wind directions and four interference conditions of twin buildings (separately for both the models). The research has been undertaken in Terrain Category II, which is the most widely available terrain in India. A comparative assessment of the two models is performed in an attempt to comprehend the various consequences of diverse conditions that may emerge in real-life situations, as well as the discrepancies among them. Experimental results of wind pressure coefficients of Model-1 and Model-2 show good agreement with various wind incidence conditions with the minute difference in the magnitudes of Cp. On the basis of wind tunnel studies, it is distinguished that the performance of Model-2 is better than Model-1 in both isolated as well as interference conditions for all wind incidences and orientations respectively.
