Why is the ceiling height of windows restricted to a maximum of 36 inches?

The restriction on the ceiling height of windows to a maximum of 36 inches primarily serves to ensure ease of access for all residents. This height allows individuals, including those with disabilities or limited mobility, to easily reach and operate the windows. Accessibility is a crucial aspect of building design, as it promotes safety and independence among all users of the space. Lower window heights can facilitate better access to fresh air and natural light, making spaces more user-friendly.

While the other options discuss aspects like lighting, ventilation, and aesthetics, the fundamental reason behind the height restriction centers on ensuring that all individuals can interact with the windows without barriers.
