For LEED EBOM 2009, IEQp1, are exhaust fan test reports required for every fan or just one per type. We have 4 restrooms with an exhaust fan in each and then 4 industrial size exhaust fans in the production area that move air from inside the building to outside to help with air circ in summer. This production area is not air conditioned. Could you also tell me the best type of equipment to use for measuring outdoor airflow at the HVAC units. This project has six HVAC units to cool the office areas and computer rooms - just simple residential-size 4-5 ton split units, so I need to describe to contractor what tool to use and where to take the measurement. Readings are not required at diffusers/vents, correct? Thanks for any help you can pass on quickly as we wrap up this project!
