1) ive looked at space matrix (this is a library project)... from what i gather EVERY space has to count.. even spaces not regularly occupied (mech closet, janitor closet, etc). Is this correct?
2) building has a large two story atrium. the floor of the atrium gets air from more than one air handler unit. how would I break this down in terms of area/AHU?
3) my understanding is that there needs to be at the very minimum, one test done per air handler unit (can be more tests if a AHU supplies more than 25,000 sq ft).. Is this correct?
4) what if there is an AHU that supplies less than 25,000 sq ft - but it supplies rooms on different floors? Would a space on each floor need to be tested?
would greatly appreciate any advice. thanks....

Refer to my previous reply. The main question that LEED does not answer is "What is a ventilation system?" If you count every VAV box and every associated thermostat in a building with this type of ventilation then you would be collecting way too many samples (in my opinion). That is why I look at number of outdoor air intakes and the areas served by each one of those. I would also recommend sampling the outdoor air at the OA intakes and using that data to correct the indoor numbers if the indoor samples fail LEED criteria. The intent statement says the credit is to reduce IAQ problems resulting from construction or renovation - not from bad outdoor air.
