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?
