The invention discloses a sun-shading system and method for a zero-energy-consumption building, and the method comprises the steps: obtaining a sun angle value, a sunlight intensity value, and a closing angle value of a sun-shading device of the zero-energy-consumption building; performing data preprocessing on the sun angle value and the sunlight intensity value to obtain a sequence of a sun angle local time sequence input vector and a sequence of a sunlight intensity local time sequence input vector; carrying out feature extraction and feature interaction association based on a similar bidirectional attention mechanism on the sun angle and the sunlight intensity so as to obtain a sun angle-sunlight intensity time sequence change fusion feature vector; determining a closing angle value of the recommended sunshade device based on the sun angle-sunlight intensity time sequence change fusion feature vector; and generating a closing angle control instruction based on comparison between the closing angle value of
