In commercial structures, skylights are typically located over which area?

• A. Over manufacturing areas
• B. Over offices
• C. Over parking structures
• D. Over storage rooms

Answer: (A)

Natural daylighting is most effective on large, open spaces where light can spread evenly across a wide area. Manufacturing floors fit this need well: they’re typically expansive, unobstructed spaces where workers perform tasks that require good visibility across long widths and depths. Placing skylights above these areas brings daylight deep into the interior, reducing the reliance on artificial lighting and lowering energy costs while supporting safer, more productive work conditions. Proper diffusion and shading help minimize glare and hot spots from direct sun, making daylight more usable on the work surfaces and machines.

Offices often rely on perimeter windows or interior daylight strategies and may not gain as much from skylights in terms of overall illumination efficiency. Parking structures and storage rooms are less about widespread daylighting—their use patterns, security considerations, and potential for glare or UV exposure make skylights less advantageous in those spaces.
