FAQs about IEQc5 :

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?

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 recall seeing a CIR a few years that addressed this issue but I'm unable to retrieve it at the Interpretations Database. Issue: we have an institutional cafeteria that has doors leading outside to a paved terrace/patio. I presume we need to provide walk-off mats for these entrances as well. Does anyone have specific experience with this condition? Note that the terrace/patio is fenced so there is no entrance/egress from adjacent surfaces (paved or vegetated). Thanks for your input. David

Yes, you would need to provide walk-off mats at these entrances. We had a similar situation on a project.
