This paper proposes a workflow based on multi-objective optimization for the design of the building envelope. The design variables of the workflow are the sorting method of sun vectors to calculate the solar envelope, the building orientation and the number of floor plan divisions. The objectives are the maximization of the building volume, the maximization of the ratio of the windows that fulfill the solar access requirement and the minimization of the mean incident solar radiation through the windows to reduce the risk of overheating during the warm season. The workflow has the potential to be adopted by designers being integrated in the Grasshopper plug-in for Rhinoceros that is a widely used design platform. The proposed workflow shows a successful way to deal with complex multi objective design goals. Multi-objective criteria based on volume and solar access achieve the best trade-off solutions with volume ratios higher than 20% and ratio of the windows that fulfill the solar access requirements higher than 57%.

Abstract
This paper proposes a workflow based on multi-objective optimization for the design of the building envelope. The design variables of the workflow are the sorting method of sun vectors to calculate the solar envelope, the building orientation and the number of floor plan divisions. The objectives are the maximization of the building volume, the maximization of the ratio of the windows that fulfill the solar access requirement and the minimization of the mean incident solar radiation through the windows to reduce the risk of overheating during the warm season. The workflow has the potential to be adopted by designers being integrated in the Grasshopper plug-in for Rhinoceros that is a widely used design platform. The proposed workflow shows a successful way to deal with complex multi objective design goals. Multi-objective criteria based on volume and solar access achieve the best trade-off solutions with volume ratios higher than 20% and ratio of the windows that fulfill the solar access requirements higher than 57%.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
