FAQs about IEQc5 :

Should track-off mats being used on the project to meet IEQc5 requirements be included in IEQc4.3 credit requirements?

What is the definition of a high-volume copier?

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

I do not have 10' of space inside my building entrance to install a walk-off system. Can I include one on the exterior? Can the shape be irregular?

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

Are entryway mats required for a building entrance from another building?

Can I use carpet tile as a track-off system? What about carpet?

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?

MERV 13 requirement in tall buildings

I am working on a CI project which is in a tall building. The building itself is not LEED certified and the air intakes of the building on 41st floor that provide air to the CI project do not have MERV 13 filters. The intent of this credit is, I believe, prevent hazardous particles that are typically from traffic and other activities surrounding the building that from entering the project space. Would this requirement be still enforced without an exception, even if physical circumstances almost guarantee that the fresh air is unlikely to be polluted at that height (41st floor)? Would it be worth writing a narrative describing that the intent of this credit is fulfilled with the existing filters?

Hi Bilge, I can't speak to air quality at the 41st floor. But I can offer that in our many CIs that occur in parts of uncertified LEED buildings, we have had to install MERV13s on rooftop AHUs that serve our project scope along with other parts of the building to comply. Good luck.

I have also always seen reviewers require MERV 13 no matter the situation circumstances. It never hurts to try a narrative, but I think it's a real long shot.
