Abstract

The objective of this research was to investigate the design collaboration of climate-based daylight evaluation and daylight design for circadian rhythm. The variables of room proportion, window to wall ratio, and orientation were considered. Rooms were modeled by Rhinoceros. Daylight performance analysis were simulated by Grasshopper and DIVA software. And, MR and EML were calculated by WELL’s tools. The results of the research showed that all of the cases that passed both sDA and ASE were the North facing opening, while using openings in other orientations were not passed the threshold. From MR and EML results, it can be concluded that daylight performance in Thailand has a good potential for providing EML. However, if referred to horizontal illuminance, it has a chance that high illuminance in the near opening area will affect user’s visual comfort. Thus, the strategies of opening design for distributing daylight or providing circadian rhythm will be a new procedure in architectural design process in order to propose practical solution in real condition.
