A Study on Parametric Design Method for Optimization of Daylight in Commercial Building’s Atrium in Cold Regions

With the development of urbanization, more and commercial buildings are built in cities, which is resulting a large amount building energy consumption that threatens ecological environment earth. Lighting occupies proportion consumption, improving quality natural daylight atriums great significance for efficiency as well indoor comfort. This paper proposes method optimizing atriums. Starting from perspective parametric design, this investigates current status theoretical research on cold regions, taking Jinan, China, an example. Dynamic glare simulations were performed using Rhino + Grasshopper Ladybug Honeybee every design parameter system, followed by correlation analysis multiple linear regression SPSS to determine degree influence each atrium. Based results above analysis, multi-objective optimization plug-in Octopus used find combination parameters can achieve best daylight. The show among total fourteen atrium parameters, seven them significantly correlated with daylight, after it found affect following order: Skylight VT, ratio, Atrium inclination, Fabric coverage, Wall reflectivity, Roof reflectivity. optimal obtained according Pareto front solution set, provides some reference ideas regions China.
