[Radiance-general] Re: effectiveness of light shelves

[Paul LaBerge]

Hi Ramana,

Light shelves do redirect light deeper into a space under both overcast 
and clear sky conditions. Whether they do this effectively and for all 
overcast and clear sky conditions depends on building and light shelf 
design. They do not necessarily block nor reduce glare. That depends on 
design particulars as well.
