Luminance of curtain wall glass

I have a question. I want to analyze the reflection luminance of curtain wall glass at a certain moment, but I have tried for a long time and still cannot get the desired result.
No matter how the setting, the result is always 119cd/㎡。
I have uploaded the file, thank you.
