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?

Historic Building Limitations

Has anyone been successful with a variance on the 10'-0" walk off-matt rule based on the limitations of a historic building? My building has an 8'-0" vestibule at the 2 main entrances. We have installed 6'-0" permanent walk off systems (metal grate in the floor) in the direction of egress. Do I need to add 4'-0" of roll-away matts on the other side of the vestibule to be compliant, or can we contend that the existing vestibule size only allowed for a 6'-0" walk-off system? The vestibule is a typical air lock type entry with two sets of doors (one at the exterior and on into the building). Any assistance would be greatly appreciated.

Todd, see the FAQ above about variances from 10 feet. You're not likely to get any special treatment as a historic building.

I didn't think so, but thought it was worth a question. I will advise the client to install the additional 4'-0" of roll-off matt (with weekly maintainance). As always, thanks...

see LEED Interpretation 10098, Applicable to v2009 projects won't help on the length but might help on the configuration? "Where there are physical impediments to locating 10 ft of walk-off mats inside the building, is it acceptable to locate a portion of the mat or grate outside and then the remainder of the required 10 ft inside?" Ruling The intent for the entryway system (grilles, grates, walk-off mats) is to capture dirt and dust. An exception to the 10 ft length and/or indoor location is acceptable provided your alternative solution meets this intent and is thoroughly justified. Applicable Internationally.
