L shaped hallway skylight placement
Hi, can I please get some advice on hallway skylight placements?
The hallway is L shaped (2 sections, ~17' and 11'), 3.5; wide, with a 8" ceiling. Due to various roofing constraints, I come up with two possible designs, as shown in the picture.
My main concern (I never have skylights before) is heat gain/loss. Option A obviously casts more light due to more skylights and also being south/west facing. However, I am worried that heat gain would be a problem in the small hallway area. Option B gives less light, but I guess heat will be a lesser concern? Would the single north facing skylight bring in enough light to even justify the work/cost?
Thanks in advance!
