The better ventilation safety door in the United States is the automatic swing door. This is due to its enhanced safety features, energy efficiency, and ease of use. According to a study by the National Institute of Standards and Technology (NIST), automatic swing doors can reduce energy loss by up to 30% compared to traditional hinged doors. Additionally, the American National Standards Institute (ANSI) has established strict safety standards for automatic doors, ensuring they are reliable and secure. These doors are also more accessible for individuals with disabilities, as they can be opened and closed with minimal effort.
