We are certifing a project with two buildings, the first is an offices, the second is a warehouses to rent in Spain.
The question is for the warehouse, this warehouse is not conditioned and the spain law (and UE) doesn't require ventilation for this type of buildings.
We don't Know the use, because it is for rent.
The question is:
To meet the crèdit -Minimum Indoor Air Quality Performance- and Leed V.4
does warehouses require ventilation? and if the answer is yes, with natural ventilation is it enough? or require mechanical ventilation?

Hi Helena,
Just seeing your post from last year. The warehouse spaces will require either natural or mechanical ventilation to meet the prerequisite. That said, some of the warehouse space may qualify as "inactive", which case that area could be excluded. In past versions of LEED, USGBC has defined inactive as nonoccupied (defined as spaces designed for equipment and machinery or storage with no human occupancy except for maintenance, repairs, and equipment retrieval. For areas with equipment retrieval, the space is only nonoccupied if the retrieval is occasional.)
A few other things to keep in mind is that there does appear to be an alternative compliance path available for projects in Europe. Otherwise, ASHRAE 62.1-2010 generally requires all naturally ventilated spaces to be mechanically ventilated as well, unless the natural ventilation openings are permanently open.
