what is dead air in abandoned buildings

Dead air in abandoned buildings refers to the stagnant air that accumulates in a building that is no longer occupied or ventilated. This can lead to a buildup of moisture, which can cause mold and mildew to grow, and can also cause the air to become stale and musty. Dead air can also contribute to poor air quality, which can be a health hazard for anyone who enters the building. In addition to dead air, abandoned buildings can also deteriorate quickly due to leaks, damage to windows, ceilings, and floors, and lack of maintenance.
