Multi-objective optimization on daylight control system's qualitative and quantitative performance

In recent years, the parametric design has become a great interest to architects. Especially in a building envelope, daylight control systems (e.g. shades, reflectors) take a method of continuous deformation until the architect finds interesting patterns or shapes that satisfy the architect's favour. However, those new design approaches bring a controversial question with a reasonable sense of priority. In some cases, aesthetic variables control the true purpose of the daylight system; contrarily, the function-oriented daylight system could mar the visual interest of architects and building users. This paper would provide a suggestion to this issue by demonstrating how aesthetic preference and daylighting performance could be well balanced by means of Multi-Objective Optimization (MOO). This paper aims to demonstrate how aesthetic preference and visual comfort can be woven together into a daylight control system. In detail, how using Multi-Objective Optimization can find a solution that fulfils both aesthetic satisfaction as a qualitative performance and visual comfort as a quantitative performance.
