This office lighting design is based with WELL Building standard (v2 2022) that requires:
‍
• L03 Part 1, the melanopic EDI of daytime light environment should be not less than 250 lx (3 points).
• L04 Part 1, the UGR should be 16 or lower (2 points).
• L08 Part 1, the CRI should be not less than 90 (1 point).
• L08 Part 2, Pst LM≤1.0 and SVM≤0.6 (1 point).
• L09 Part 1, Color temperature and distribution of light can be changed and controlled both manually and by computer (2 points).
