In a 100 sq ft bedroom, what is the minimum total openable area of a window required?

The minimum total openable area of a window in a bedroom is determined by safety and ventilation requirements outlined in the International Property Maintenance Code. For a room used for sleeping purposes, adequate ventilation is essential to ensure a healthy indoor environment.

In this context, the requirement for openable area is usually aimed at providing a minimum percentage of the floor area of the room. Following general guidelines, a total openable area of 3.6 square feet is sufficient for a 100 square foot bedroom, as it meets the ventilation needs while promoting safety for the occupants. Specifically, this figure corresponds to approximately 10% of the floor area, aligning with recommendations for adequate airflow and emergency egress.

This requirement helps ensure that occupants can exit quickly in case of an emergency, such as a fire, while also supporting adequate air circulation, making 3.6 square feet the correct answer.
