    Abstract
    Building skin can provide comprehensive functions of energy production, daylighting and shading with the transmissive concentrating panel integrated. A comparative study was conducted on the three variables of the size, rotation angle and number of concentrating modules based on the parametric modelling platform of Rhino-grasshopper, performance simulation platform of Ladybug tools and multi-objective optimization platform of Octopus. The optimal solution was designed, and the multi-objective optimization technical framework of the office space was constructed by solving the optimal relationship between the light environment quality and energy output efficiency of the solar concentrating skin. The results showed that the dynamic solar concentrating skin can effectively reduce the Daylighting Glare Probability (DGP) and increase the Useful Daylighting Illumination (UDI) while achieving energy output by comparing the office space with integrated solar concentrating shutters, ordinary shutters and no shutters. Then the optimal design interval of each variable of the solar concentrating skin was obtained through the scheme comparison. This study can provide a method for improving the balanced design of indoor light environment and building productivity efficiency, and provide a technical framework for the multi-objective optimization process. And it also can provide a reference for the integrated design of dynamic concentrating skin and building.
