What is the definition of a high-volume copier?

Do I need to provide dedicated exhaust for my printer or copier?

What does ‘regularly used exterior entrance’ mean and how do I know which of my building entrances falls under this category?

Our building has a green cleaning program and is earning an ID credit for it, based on the LEED-EBOM IEQc3 requirements. Can we skip the exhaust requirements for our janitor rooms?

Regarding the MERV filter, I had advised the M&E the LEED Requirements and he has replied as "During the test run period (80days), the MERV 8 will be installed on the AHU, PAH & VRF Indoor Unit. After test run, new MERV 8 and MERV 13 will be installed on the AHU, PAH & VRF Indoor Unit to filter the return air and outside air". is ok if MERV 13 is not provided during the test run period? Kindly advice.

On the form for this credit, you will have to check a box that says: "Supply air systems, including both outside air and return air delivered as supply, serving all regularly occupied areas are sized to accommodate filtration media with a MERV rating of 13 or better. New filtration media which meet this MERV rating will be installed prior to occupancy." The strategy you are describing does not seem to be in line with honestly checking this box on the form, so I would recommend that you make sure the MERV 13 filters are installed before building occupancy.
