Hello, we are dealing with the interior project of a beauty shop.

Some of the space in the project is ventilated with an Energy Recovery Unit and an Exhaust Fan.

ERU did not meet the minimum ventilation of ASHRAE62.1, so an exhaust fan was additionally installed.

Exhaust fan meets ASHRAE 62.1-2010 Table 6-4 Minimim Exhaust Rates.

Do I need to prove make up air for exhaust air in this case?
