What is the minimum window area required for a naturally ventilated habitable room?

The minimum window area required for a naturally ventilated habitable room is generally set at 1 square meter. This requirement is established to ensure adequate ventilation and natural light, contributing to a healthy indoor environment. The window size not only facilitates airflow but also allows occupants to benefit from daylight, which is essential for both physical and psychological well-being.

In the context of building regulations, this specific measurement helps to standardize design practices, ensuring that rooms designated for habitation meet a fundamental level of comfort and safety. Natural ventilation is particularly important in residential settings, where stagnant air can lead to a variety of issues, including poor indoor air quality and moisture-related problems.

Therefore, the stipulated minimum window area is a critical guideline in architectural design, emphasizing the importance of light and ventilation in promoting a healthy living space.
