One floor underground parking lot with 30m * 390m dimension in Tropical Island. There are not any opening in all side of parking lot except 2 car entrance, but I want to design some opening in top of parking lot. So question is "minimum number of opening (place and area of opening) that needed to make this parking lot, an open parking."
