How do you calculate the light refectance value of a glass partition? Also patterned wallpapers, manifests and screen prints where the information is not available from the manufacturer?
Any help would be much appreciated!

Hi Karen,
I'm curious if you ever received any further guidance on this question?
Or if you've received any further feedback from reviewers during the submission process? Thanks!

Hi Simon
We used the BS standards for them. We have not submitted yet, but hoping to soon. I will let you know what the feedback is when we get it.
Karen.

Hi Karen, What is the "BS standard"? Have you received any feedback on getting LVR values from vendors?

The BS standard we used is BS 8206, Lighting got buildings, Part 2. Code of pacatice for daylighting. The LVR table in it only has a handful of materials, but does have window glass (used internally), which is 0.1.
We have ended up abandoning the credit as too many products fell under the limit, so I didn't end up asking the vendors, sorry.
