OR
-Located in a jurisdiction where smoking is banned outdoors, except in designated areas. Such designated areas must be more than 50 m [164 ft] from all functional building entrances, and smoking ban must be enforced.
Projects may achieve Feature 02, Part 1 by providing smoking areas within the project boundary that meet the following requirements:
1. Clearly designated as a smoking area.
2. Independently ventilated and negatively pressurized to prevent smoke from escaping, as per either ASHRAE 62.1-2013, Section 5.17 or LEED NC 2009 IEQ prerequisite Environmental Tobacco Smoking (ETS) Control, Option 2 Case 1 Non-Residential Projects.
3. Uses doors that are equipped with self-closing mechanisms on all entrances.
4. Constructed of materials and furnishings with low absorptive and non-porous characteristics.
5. Does not allow persons under the age of 18 to enter.
6. Contains prominently-displayed smoking cessation and health education signage and does not contain entertainment amenities.
7. When cleaned, cleaning staff are provided with P100 respirator masks.
8. If the smoking area is repurposed, all materials within the space must be discarded.

During performance verification, one of the sampling points for Feature 01 will be 2–5 m [6.6–16.4 ft] meters from the door to the smoking room and the door will be opened at least once every ten minutes during the testing period.

For Feature 02, Part 2, project may have outdoor smoking areas (e.g., on a roof or patio), provided that these areas are at least 8 m [26 ft] from outdoor air intakes and operable windows. There must be at least two regularly closed doors (or one revolving door) between the smoking area and any regularly occupied interior space for any entries within 8 m [26 ft] of outdoor smoking area. Project must include an identical (or superior) outdoor area where smoking is banned at least 20 m [66 ft] from any other outdoor area where smoking is allowed.

A project using this AAP is limited to Silver level certification, unless it:
- Achieves Feature 95: Stress and addiction treatment, in which case it can achieve Gold.

In addition to original documentation, an architectural drawing must be provided which indicates location, entrances, and wall construction of smoking area. Furthermore, the MEP engineer must provide a Letter of Assurance that the ventilation and pressurization requirements are met. Proper signage must be posted at the entrance to the smoking area and is subject to a spot check during performance review.

Previously published as an AAP:
Field and Laboratory Emission Cell (FLEC) emissions testing is approved as an emissions testing methodology only for furniture and furnishings that are made up of a uniform material and have flat testing surfaces on which the FLEC emissions testing methodology may be applied. For example, flat surfaced cabinetry that is made up of a uniform material may be tested using this methodology. However, chairs that are made from a variety of materials that lack flat surfaces may not be tested using this methodology. The emissions test must be administered by a third party investigator with no affiliation with the project. The associated costs are the responsibility of the project team.
