Do I have to achieve Option 1 if I want to pursue Option 2?

Has the pressure differential requirement of at least 5 pascals for LEED 2009 EQc5: Indoor and Chemical Source Pollutant Control been eliminated from the requirement of this credit?

NC-v4 EQc1:Enhanced indoor air quality strategies

V4 Entrance mats/roll-up mats

Hi, does anyone know if the v2009 interpretation still applies that the first 3 ft of the 10 ft must be a permanent system (like recessed mat system) and the remainder can be roll-up mats.  Or with the new wording in v4 can the entire 10 feet be made up of rolling/walk-off mats if they are serviced weekly? this is for a school.  thank you

Although I can't pinpoint in my head exactly which project I've had do this, I know there have been several that had only roll-up mats and no permanently installed portion, and it was fine with confirmation from the owner regarding the maintenance. I've never had a review comment come back requiring a portion of it to be permanent.

Same here, like Emily says, I have had 3 m long roll-out mats with no part permanent in both v2009 and v4.
