What is the minimum height for a plume discharge above an inlet to a building?

The minimum height for a plume discharge above an inlet to a building is established to ensure proper ventilation and prevent the reintroduction of exhaust gases into the building's air supply. The standard for this height is set at 5 feet.

This requirement is crucial for maintaining indoor air quality and safety. By ensuring the plume discharge is above the building's air intakes, it minimizes the risk of contamination from potentially hazardous gases such as carbon monoxide or other pollutants that might be present in the exhaust.

Adhering to this standard helps to promote good practices in HVAC design and installation, ensuring that systems operate efficiently while prioritizing occupant health and safety.
