We have been pursuing Strategy E, Option 2 in the Interior Lighting credit.  We have sealed concrete floors in most of the spaces, which is obviously done in the field and there is no manufacturer's product data for the final finish, so we would have to go to the project site and measure the LRV directly.  Would USGBC accept LRV from the Color Muse device?  https://colormuse.io/color-muse.html
