Hi all,
We have an existing building built in the early 1900s with three 100% make up air units supplying fresh air with no exhaust. The building is pressurized and fresh air exits through the building envelope. We have taken supply air measurements. What are the EQp1 guidelines for exhaust system tests on pressurized buildings without exhaust fans? There are four small evacuation fans for each bathroom which evacuate less than 5% of the total supply air.
Thank you for your help with this question.

It sounds to me like you would test for proper functioning of the evacuation fans and then include a narrative with the prerequisite submittal summarizing the building's strategy related to pressurization and exhaust.
