What is the minimum ceiling height required for an artificially ventilated habitable room on the third floor and above?

The minimum ceiling height required for an artificially ventilated habitable room on the third floor and above is 2.4 meters. This requirement is set to ensure that the space is comfortable, safe, and suitable for living purposes, providing adequate circulation of air and light within the room. Ceiling height is a critical factor in design standards to ensure health and safety, especially in residential buildings where occupants may spend significant time.

A height of 2.4 meters meets the usability standards for living spaces while allowing for sufficient air movement that artificial ventilation systems can provide. This standard reflects the balance between maintaining an open and inviting environment that doesn’t feel cramped or restrictive. In contrast, higher ceilings could provide additional benefits, but they are not mandatory for the minimum requirements in specific contexts.
