I looked through the archives and saw some discussions with this topic, but
wanted to ask the questions again. I need to model light shelves for the
aspect of reducing HVAC equipment size, with no regard to the daylighting,
as of right now. This will be an issue, but i just want to see the
difference in the HVAC sizes. Is the correct way to apply the light
shelves to use an over hang in the window properties? or should i use a
shading schedule? or should i use a building shade? My first guess would
be over hang, but i haven't used these for this reason, so i wanted input
from others.

Thanks,
