A room's window area is being checked for natural light. A common code benchmark for required glazing (natural light) in a habitable room is a glazed area of at least ____ of the floor area of the room.
a.25 percent
b.1 percent
c.8 percent
d.50 percent
Explanation
Habitable rooms typically must have glazing (for natural light) equal to at least 8 percent of the floor area, with about half of that openable for ventilation, unless mechanical/artificial systems are provided. Twenty-five and 50 percent are far above the minimum, and 1 percent is far too little.
