Stupid question: Wouldn't the snow cover the vault lights? (I know, they could clear them by clearing the sidewalks...)

- jrace 7y agoIt would. But not 100%. Same with skylights, depending on the depth and density some sunlight still makes it
- sampo 7y agoSnow also scatters light a lot, if it's not too dirty. One example I found, it takes about 8 cm (3 inches) of snow to reduce the light irradiance to half.
- jrochkind1 7y agoThey weren't clearing the sidewalks to let light through, they were (and we are) clearing the sidewalks so that people could walk on them! Anyway, with or without prism tiles.
