For resident rooms, the required floor area must ensure how many windows to the outside?

The correct answer indicates that resident rooms are required to have windows providing access to natural light equal to one tenth of the room area. This standard is grounded in health and wellness regulations, which emphasize the importance of natural light and air circulation in living spaces, particularly in health facilities where residents may be more vulnerable.

Having a minimum window area allows for increased daylight exposure, which has positive effects on mood, mental health, and overall well-being. Such standards are important not only for comfort but also for aiding the healing process.

The requirement that this window area be at least one tenth of the room area ensures that all residents benefit from adequate lighting and ventilation. By adhering to these guidelines, facilities can create environments that support the physical and psychological health of their residents.

In contrast, options suggesting a higher proportion, such as one half, one quarter, or one eighth of the room area, would likely exceed the necessary requirement for natural light and could place undue architectural constraints on facility design. This could detract from the effectiveness of the space as a health environment rather than enhancing it.
