We are finishing a LEED CI certification in a building that was LEED NC certified several years ago. (Clearly it passed EQp2 regarding the smoking policy.)

For this project we have provided the template and photos of the signage on the entrances. The signage indicates the building is smoke-free but does not stipulate (explicitly) that smoking is prohibited within 25'. They have asked up to provide further documentation that indicates smoking is prohibited within 25' of all entries, intakes, windows...

The company has a written policy which has been in place since 2006 and our intention is to provide this to support the signage.

My question: Are we REQUIRED to post signage on the doors and other areas of the campus that say the 25' limit? Is the existing signage accompanied by the written policy not enough?
