Résumé
In this study, we demonstrate that upstream buildings exert a significant influence on the wind conditions at rooftop levels for energy generation. By systematically removing, adding, and modifying the layout of a section of the University of Alberta North Campus, we conclude that the obstructive effect of upstream buildings is a cumulative phenomenon. This finding adds complexity to urban wind energy assessments that are based on city morphology.A series of CFD simulations, comparing various building modifications (including the removal of tall obstructions, sheltered structures, and alterations to roof shape) revealed that changes in building inclusion can lead to substantial variations in both wind velocity and energy yields. These variations underscore the importance of understanding the complex interactions between urban structures and the wind.Following an initial exploration of building interactions, we are performing a systematic CFD simulations aimed at identifying the key variables that govern this cumulative influence. The objective is to characterize how factors such as friction velocity, surface roughness, building width, and relative distance (normalized by a characteristic height difference) affect urban wind flow. The results of this investigation are intended to guide the appropriate inclusion of upstream buildings in CFD simulations, and they highlight the need for further validation through wind tunnel experiments and field measurements.
