FAQs about IEQc5 :

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 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?

Does anyone know if the requirements of this credit can be met with a split-system for an exercise room if the outdoor air ONLY has the MERV 13 filtration? There is no return air on the unit.

Patrick, This seems fine. If you have no return I assume you are direct ducting the return of the spilt unit to the outside. Then you are putting MERV 13 filters in that duct or the back of the split unit. How is the air exiting the space? Do you have constant exhaust? Or a relief?
