Resumen
Building skin can provide comprehensive functions of energy production, daylighting, and shading with an integrated transmissive solar-concentrating panel. In this study, Rhino Grasshopper parametric modeling, Ladybug tool performance simulation, and Octopus multiobjective optimization platforms are used to carry out experimental research. This study establishes the optimal relationship between the conflicting objectives of light environment creation and energy production efficiency of solar-concentrating skin by controlling three variables, namely the size of the solar-concentrating module, the rotation angle, and the number of modules, aiming to design the optimal solution and build a multiobjective optimization technology framework for the solar-concentrating skin of an office space. A comparison and analysis of the scenarios indicate a dynamic concentrating skin that can effectively reduce the daylight glare probability (DGP) by 70% and increase the useful daylight illuminance (UDI) by 10%, while achieving energy production. The correlation between the variables and the performance indices of the solar-concentrating skin was obtained as angle > width > length > amount, and the optimal design interval for each parameter variable. This study reveals the laws of how parameter changes affect individual indicators, which can provide ideas for the design of dynamic concentrating skins and building integration, methods for improving the balanced design of indoor light environments and building capacity, and a technical framework for multiobjective optimization processes.
