The minimum ventilation requirement for Type R construction, specifically for residential buildings, is crucial for ensuring adequate air quality and preventing the accumulation of moisture and pollutants. In this case, the correct answer is based on established building codes and standards that outline the necessary ventilation for various types of construction. For Type R construction, which refers to residential buildings, the requirement is set at 25 square feet. This ensures that living spaces have sufficient fresh air circulation, contributing to a safe and healthy indoor environment. Adequate ventilation helps to mitigate risks such as mold growth, excessive humidity, and the buildup of indoor pollutants, which can adversely affect the health of occupants.
