We have a question regarding the ventilation requirements on corridors in order to comply with requirements of Minimum Indoor Air Quality Performance prerrequisite.
Do we need to provide outdoor air to all the corridors or can we exclude "inactive corridors", corridors occupied only for short periods of time?
Do we need to ventilate spaces such as corridors leading to restrooms, corridors on emergency exists, corridors within the data center?
Best regards,

Hi Sofia, if you are using ASHRAE 62.1 to demonstrate prerequisite compliance I think you have to ventilate every "occupiable" space, as defined by ASHRAE 62.1: "occupiable space: an enclosed space intended for human activities, excluding those spaces intended primarily for other purposes, such as storage rooms and equipment rooms, that are only occupied occasionally and for short periods of time."
This includes corridors. Note that supplying outdoor air directly into the space is not the only method accepted to ventilate a room.

"regularly occupied" and "non-regularly occupied" occupiable spaces are required to be ventilated.
"unoccupied" occupiable spaces are not required to be ventilated. Mechanical rooms and inactive storage spaces are typically considered to be unoccupied occupiable space and therefore are not included within our ventilation calculations for LEED.
