The using of generative algorithm aided design tool (Rhinoceros/Grasshopper/Ladybug) to control solar access in urban street of hot-arid climate (Ouargla)

Abstract

Solar control is a major factor for thermal conditions in built forms. The intention of this study is to develop a parametric approach of generative algorithm aided design (Rhinoceros-Grasshopper- Ladybug) that examines and evaluates the effect of street geometry on solar radiation on ground surface of urban street. In order to achieve this aim a model of contemporary urban street will be analyzed. The investigation was conducted during summer period (21 Juin-21st September) in city of Ouargla (Algeria) characterized by hot dry climate. The results reveal that a number of useful relationships can be developed between the geometrical parameters of urban street dimensions, and solar radiation on ground surfaces of urban street
