Some units are tagged as RTU and others are tagged as AHU, and some units do not appear to have any tag numbers. For example, two rooftop units (RTU) near AHU-6 and one near AHU-5 do not appear to have tag numbers. On one unit tag number is hand written as #8 but very hard to see.
No tag number on one exhaust fan near AHU-8.

Lot of inconsistency on the position of the outside air dampers (OADs) from one unit to the other. On some units OADs appear to be 100% open while on other units the OADs are partially open, and on some units they are closed. For example, AHU-3, AHU (no tag number located near AHU-5) and RTU-13 OADs 100% open. AHU (no tag number located near AHU-6) OADs open. but less in comparison. RTU-12 - OADs closed.
