Hello, I got a sample script from GitHub as I am trying to calculate ASE and sDA, I modified it to fit my needs but whenever I Run the simulation it gives me values of 0/ null. Am I missing something? File attached as drive below.

My apologies! should be accessible now. Thank you!!

Hi @minggangyin were you able to open the file? I found out the problem comes from this component. How to address this error?

Looks to me that either you haven’t installed radiance to C:/radiance (default installer picks C:/program files/radiance for you), or that LBT can’t find it.

There might be a way to manually set it in LBT. It looks like it in the popup message.
