Multi-objective energy and daylight optimization of amorphous shading devices in buildings

•A novel shading design enhanced by multi-objective optimization is presented.•The amorphous shading device reduced total energy consumption of an office room up to 14%.•Minimization of total energy consumption and maximization of UDI are the objective functions.•We use surrogate modeling by making regression analysis of each daylight point.•Performances of two Pareto fronts are compared using Hyper Volume indicator.
