Hi everyone,
Although I read almost all the comments related with the ventilation requirements of the storage rooms, I could not find the exact answer for my question.
In our project we have a storage room (definitely will be visited maybe once a month for 10 min and will store no chemicals etc..), with just a small operable window, which is not providing %4 area condition.
Some comments say that "Storage Rooms" can be excluded from VRP calculations, but also some refers to ASHRAE 62.1-2007 table for Ra rate to be provided. So my question:
Should I exclude this area with a strong narrative for this prerequisite? or
The natural ventilation with small window for a storage room will be enough although it is not %4 by area?

Hello-
My understanding is that a storage room that is visited only once a month for 10 minutes can be classified as "Inactive" Storage. Spaces such as these do not need to be included (per the IAQ matrix spreadsheet), because they are considered unoccupied spaces.
Whether there is a window or not is irrelevant for compliance because the space does not have to be included at all.

Thanks Julia for your comment. Seems like no LEED User experts are replying any questions here any more...

I concur with Julia's comment.
to add:
Inactive storage is further defined as "unoccupied space" thus not requiring ventilation per IEQp1. Be sure to describe the function/use of the room to reviewer when submitting your project.
good luck!
