I am working on a project where one of the janitor's closets is located in the kitchen area.

a small printing room in an open office, no enclosure for the printing room. but on the top of the printing room, we have an exhaust fan for pollution air. so can we earn IEQ credit5

If a project space does have printer areas in the open plan office but those printers/copiers are low-use, are there any additional details we need to provide or should we just mention these printe

What is meant by "Average Differential Pressure"? In my case, i have 4 janitor's closets and a recycling room on the same fan.
