May be the only legal option
Interior smoking is not allowed in many building types, and for those projects, this prerequisite should be easy and not add costs. It may even be the only legal option. To comply, you may need to establish a nonsmoking policy in and around the building (including entrances and balconies), and install appropriate signage.
If smoking is allowed, stringent measures needed
Multifamily residences and hotels may feel compelled to allow smoking in some or all units, and some projects, like airports, have designated smoking rooms. In these cases, stringent measures will be needed to stop movement of smoke from smoking to nonsmoking areas. These measures include air barriers between units, negative air pressure in smoking areas, separate exhaust systems, and blower-door testing, all of which may add design and construction costs. The added trouble of these measures is offset by some added benefits. The air barrier in particular can improve energy efficiency as well as acoustical privacy.
Warning: Get ready for your blower door test
Meeting the air leakage rateThe speed at which an appliance loses refrigerant, measured between refrigerant charges or over 12 months, whichever is shorter. The leakage rate is expressed in terms of the percentage of the appliance's full charge that would be lost over a 12-month period if the rate stabilized. (EPA Clean Air Act, Title VI, Rule 608). requirements for projects that must perform blower-door testing (multi-family and hotel projects allowing smoking) can be extremely challenging and a major barrier toward achieving LEED certification. The leakage rates require construction practices for unit sealing that are far beyond standard practice and as a result, many projects have failed the blower door tests and have not been eligible for certification.
It is critical that a blower-door-testing consultant be brought onboard during design development or early duing construction documents to ensure that drawings are detailed enough to properly seal units. Get the whole team, including the commissioning agent, general contractor, and subcontractors on board with the necessary practices, and keep this same expert involved during construction to ensure proper sealing techniques are being followed.
Project teams should perform a mock test of a typical unit to ensure sealing techniques are being followed and to identify any potential locations of air leakage. This ensures that problem areas are identified early on in the construction process so that problems can be corrected for the remainder of units. It can be very costly to correct common problem areas across a project if the testing is only done at the completion of the project.
Use these questions to assess your project's compliance with this prerequisite
- What is the project’s smoking policy?
Smoking Not Allowed
- If designated smoking areas are used, are they located 25 feet from entrances (primary and secondary), operable windows, and ventilation intakes?
- Has the building indicated smoking areas and nonsmoking areas with appropriate signage?
- Will smoking be prohibited on all areas of balconies and decks, even for private residences and hotel rooms, that are within 25 feet of entries, outdoor air intakes and operable windows of common spaces or other units?
Smoking Allowed in Designated Interior Spaces
- Has the mechanical system been designed to meet the necessary negative pressure requirements?
- Have designated smoking areas been designed to adequately seal and minimize smoke transfer?
- Have deck-to-deck partitions and other air-sealing construction practices been integrated into construction specifications?
- Has a blower door or equivalent testing agent reviewed the construction documents to identify areas for potential air leakage?
- Has the client been informed of the potential expense for blower door testing?
- Has the contractor briefed subcontractors and installers about best practices for sealing smoking units?
- Have air testing schedules been integrated in to the general construction schedule?
FAQs for IEQp2
Municipal law requires that our building be completely smoke-free inside. It also bans smoking next to the building, but it’s not as stringent as the 25 foot LEED requirement. Do we have to make another policy that bans smoking within 25 feet?
Yes, if local regulations are not as strict as LEED, you must create a policy that complies with LEED standards (and communicate this policy to building users) to achieve this prerequisite. Exterior signage which communicates the policy is required so that all occupants, visitors, and passersby are made aware of the exterior smoking policy.
Our outside smoking area is located less than 25 feet from an emergency exit. Is this okay since that door is rarely (if ever) used?
The Reference Guide doesn’t explicitly make a distinction between a regular door and an emergency exit, making this a bit of a gray area. The safest bet is to assume they’re treated the same way under this prerequisite, which would require relocation of the smoking area to a compliant distance. If you’d like a definitive answer to this question you can submit a CIRCredit Interpretation Ruling. Used by design team members experiencing difficulties in the application of a LEED prerequisite or credit to a project. Typically, difficulties arise when specific issues are not directly addressed by LEED information/guide.
How do you calculate the 25 ft. rule from designated smoking areas to building openings?
The 25 feet should be calculated from the closest point within the smoking area to the building opening, going around any solid objects (balconies, walls, etc.) as needed. For calculating distances between a lower level smoking area and an upper floor building opening, it should be calculated starting from the ceiling of the lower floor to the nearest (lowest) point in the upper floor opening.
We have a strict no-smoking policy and local smoking laws that all our employees are familiar with. Can we skip the signage?
No. Visitors and other non-employees might not be familiar with the building policies or local smoking laws.

At a minimum, the smoking room must be directly exhausted to the outdoors, away from air intakes and building entry paths, with no recirculation of ETS-containing air to nonsmoking areas and enclosed with impermeable
deck-to-deck partitions. The smoking room must be operated at a negative pressure, compared with the surrounding spaces, of at least an average of 5 Pascals (Pa) (0.02 inches of water gauge) and a minimum of 1 Pa (0.004 inches of water gauge) when the doors to the smoking rooms are closed.Verify performance of the smoking rooms’ differential air pressures by conducting 15 minutes of measurement, with a minimum of 1 measurement every 10 seconds, of the differential pressure in the smoking room with respect to each adjacent area and in each adjacent vertical chase with the doors to the smoking room closed. Conduct the testing with each space configured for worst-case conditions of transport of air from the smoking rooms (with closed doors) to adjacent spaces.
CASE 2. Residential and hospitality projects
Prohibit smoking in all common areas of the building.
Locate any exterior designated smoking areas, including balconies where smoking is permitted, at least 25 feet (8 meters) from entries, outdoor air intakes and operable windows opening to common areas.

Smoking areas
We prohibit smoking in our office buildings, but have a central plaza which will provide designated smoking area. Question: does that designated smoking area need to be covered? Thanks!!
No, not according to LEED. However, if on a practical basis smokers might gravitate to covered areas closer to the building, you might want to consider it.
Thanks Tristan!!
Smoking Room Testing
Dear Leedusers,
our project will include one smoking room within a restaurant space. However, the tenant will construct this smoking room during his fit-out works and therefore we are unable to provide testing data for the interior smoking room in either design phase nor during construction phase (the fit-out will be delayed).
Nevertheless, the CS building has necessary ductwork prepared but from my point of view the smoking room is out of our CS scope.
Any thoughts about it?
Jiri, see the LEED BD&C Reference Guide, appendix 4, Case C.
I expected this answer. Thank you Tristan for confirmation.
Multi-unit residential buildings
According to the reference guide, there are:
CASE 1 OPTION 1, where smoking is prohibited,
CASE 1 OPTION 2 (Non-residential projects), where smoking is prohibited except in designated areas, AND
CASE 2 (Residential and Hospitality Projects), where smoking shall be prohibited in all common areas and within 25ft of entries, and some requirements are set for private units, such as weather-strip exterior windows and doors, sealing of vertical chases, and ANSI/ASTMVoluntary standards development organization which creates source technical standards for materials, products, systems, and services-E779-03 compliance.
We have noticed that CASE 1 OPTION 2 allows areas for smoking since these are designed accordingly (isolation smoking rooms), BUT IT IS NOT CLEAR WHETHER THE SMOKING ROOM IS REQUIRED FOR CASE 2.
Hence, for a multi-unit residential building (CASE 2):
1. Shall each apartment be treated as an isolation smoking room and have their ante rooms at entries? (As long as smoking is prohibited at balconies, CASE 2 requirements are met, and each apartment HVAC system is designed so there is no recirculation of ETSEnvironmental tobacco smoke (ETS), or secondhand smoke, consists of airborne particles emitted from the burning end of cigarettes, pipes, and cigars, and is exhaled by smokers. These particles contain about 4,000 compounds, up to 50 of which are known to cause cancer. to other dwelling units)
OR
2. Are isolation smoking rooms required for each apartment?
OR
3. In case isolation smoking rooms are not required, must be there a very specific area within the dwelling unit where smoking is allowed? (in other words, in order to respect the 25ft minimum distance from entries, shall smoking be prohibited in every small room that is exposed to the outdoors? The concern would be to protect the entries of adjacent apartments).
Marcio, I think that you could treat an entire apartment as a designated smoking area as long as all the detailed requirements are met.
Core and Shell project including restaurant
Our project is a C&S building with a restaurant on the ground floor. A tenant has been already appointed but he wants to have his restaurant meant for smokers. My question is: is it possible to designate the whole restaurant as one smoking space with required construction adjustments (separate exhaust system, insulation etc.) with all necessary testing?
Thank you in advance for any suggestion and thoughts.
Jiri
If the restaurant has the chance for non-smokers to be inside then it is not a designated smoking space.

The prerequisite requires, "Zero exposure of nonsmokers to ETSEnvironmental tobacco smoke (ETS), or secondhand smoke, consists of airborne particles emitted from the burning end of cigarettes, pipes, and cigars, and is exhaled by smokers. These particles contain about 4,000 compounds, up to 50 of which are known to cause cancer. by prohibition of smoking in the building, OR, provide a designated smoking room designed to effectively contain, capture and remove ETS from the building". The CIRCredit Interpretation Ruling. Used by design team members experiencing difficulties in the application of a LEED prerequisite or credit to a project. Typically, difficulties arise when specific issues are not directly addressed by LEED information/guide narrative implies that the entire restaurant is being treated as a smoking room. While this approach will prevent building occupants in other spaces within the building from tobacco smoke exposure, it does not protect non-smoking restaurant patrons from smoke within the space. If smoking cannot be prohibited in the restaurant, the project team and owner may wish to consider creating a fully contained smoking section within the facility that meets the requirements set forth under the prerequisite. Applicable Internationally.
Thank you for such a fast reply. So if we create a fully contained smoking section for cigarette-loving customers within our restaurant, we will comply?
Is the staff serving that side of the restaurant also all smokers? It will be a difficult case to prove. There is a more recent interpretation about connecting a new building to an existing building with smoking. I've modified the text below to your situation. You may want to submit your own official question to GBCI for a ruling.
Measures must be taken to ensure that Environmental Tobacco Smoke from the smoking space does not enter the new building. There must be self-closing doors and impermeable deck-to-deck partitions separating the building from the smoking space. Furthermore, there must be an exhaust system sufficient to create a negative pressure differential between the building and the smoking space (or connecting corridor) of at least an average of 5 Pascals (Pa) and a minimum of 1 Pa when the doors between the building and the smoking space are closed. Performance of the required air pressure differentials must be verified by conducting 15 minutes of measurement with a minimum of one measurement every 10 seconds. Note that we are essentially requiring isolation of the connected smoking space with mechanical exhaust as if it were a designated smoking room with respect to the LEED-certifying building. Please refer to Option 2, Case 1, of IEQp2 for additional details on how to properly isolate, and verify the performance of, a designated smoking room. Smoking must also be prohibited within the smoking space within 25ft of the connection to the rest of the LEED building. All other requirements of IEQp2 must also be met for the new building pursuing LEED Certification.
Residential Blower Door Test results
Our Blower door tests of the residential top floor of a mixed use building reports the findings as Total Airflow through the door seals [m3/h] at a given pressure differential [Pa]. The also calculate Airflow through 1m of joint [m3/(h*m)], which both make sense.
But the credit requirement indicates square inches of leakage (per 100sqft of enclosure area.)
How do we go from measure airflow at a given pressure to an 'assumed' leakage area? (obviously we can calculate the enclosure area, but I am stumped by this demonstrated leakage area.)
Please advise.
Hi Cory, please check this: http://www.greenbuildingadvisor.com/blogs/dept/musings/blower-door-basics. Further down the page you will find explanations that should answer your question.
Comments appreciated.
No-smoking Signage provided as part of tenant package
Hi,
I am working on a LEED CS project with a single tenant. The tenant has a no-smoking policy and is providing signage throughout the property and building. Would it be acceptable for the CS project to submit the tenant no-smoking signage (part of tenant package) as documentation for IEQp2? The tenant has a 20 year lease. If this is not acceptable we will end up with 2 sets of signage...!
Any insight would be great.
Thank you.
Sarah, based on CS Appendix 4, I think this approach shoud be fine.
On-property smoking
Hi!
I'm working on a project of a multifamiliar building and we've chose Option 2, Case 2.
It's prohibit to smoke in all common areas, except on a specific area more than 25 ft from entries and openings, and we're going to make a blower door testA blower door test gives an overall value for airtightness of a space, and can help identify air leaks. The testing unit consists of a calibrated fan that is sealed onto the unit entrance. The fan creates a continuous flow of pressure into the unit (or out of the unit when using theatrical fog to locate leaks). Devices detect the rate of pressure retention and loss due to possible air leaks in the construction. to demonstrate the acceptable sealing of residential units.
But we understood that it's also necessary to prohibit smoking inside the appartments, is that right? It's really difficult to control and assure that the tenants won't smoke inside their own properties.
If we garantee that the appartment is well sealed, it's still necessary to prohibit on-property smoking??
Thanks!
Angela,
If this is a residential project then you must "prohibit smoking in all common areas of the building," but not in the residential units themselves. There are a number of requirements for Option 2 Case 2: Residential Projects. I would suggest reading through those in the Credit Language tab above.
Thanks Emily!
One more question...
We thought we would be able to run the blower door testA blower door test gives an overall value for airtightness of a space, and can help identify air leaks. The testing unit consists of a calibrated fan that is sealed onto the unit entrance. The fan creates a continuous flow of pressure into the unit (or out of the unit when using theatrical fog to locate leaks). Devices detect the rate of pressure retention and loss due to possible air leaks in the construction. but we're having a lot of trouble in finding someone to run it for us. As far as we know, there isn't anything similar here in Brazil, neither anyone to run the test nor a local standard that assure something like that.
We've found an enterprise that runs a test with infrared and generates thermal images that allows to calculate the volume of air that can leak from the appartment. It can be accepted as an alternative compliance path?
If the answer is no, then what other way we could prove that there isn't leak of air?
Thanks again!
Hi Emilly!
We still hadn't found someone to run the blower test for us, any suggestion of an alternative compliance for our project? We're running out of time.
If we decide to use the infrared, does it have any chance the reviewers to accept it?
Thanks!
Angela,
Unfortunately, I don't have experience using this alternative compliance path. It sounds like the method you described might be acceptable, but I cannot say for sure. You may want to repost your question under ACP - Alternative Compliance Paths for international projects here on LEED User.
Good day! My project is
Good day!
My project is residential, pre-certified in Core & Shell. In our project will be no smoking in common areas of the building. Being allowed to smoke only in a smoking area open to the outdoors, more than 25 feet from any building entrance.
The apartments of the residents are not certified because the certification is only the common areas and within the apartments do not have the owner to prohibit smoking.
So my question is:
I need to do the blower door testA blower door test gives an overall value for airtightness of a space, and can help identify air leaks. The testing unit consists of a calibrated fan that is sealed onto the unit entrance. The fan creates a continuous flow of pressure into the unit (or out of the unit when using theatrical fog to locate leaks). Devices detect the rate of pressure retention and loss due to possible air leaks in the construction. in apartments, or in any other area of my building? Since we have no closed rooms for smokers.
Thank you!
Joaquim, you would have to comply with the requirements of Option 2, Case 2, as outlined above under the credit language. In that case, blower-door testing is one of the requirements.
Non-Smoking Signage
Dear all,
We're going for Option 1 of this prerequisite for a very large retail mall.
No smoking will be allowed indoors, and we will provide "NO SMOKING" signs internally.
Any thoughts on the required number of signs per floor and in the parking?
Or should the Architect decide on the optimum number?
Thanks!
George, the architect should decide on this. It's not an exact science, but there should definitely be plenty of the signs.
ETS - Testing
Hello,
we are currently working on a project and the owner intends to include several smoking rooms for the project.
Will the team be required to conduct blower-door-testing for each and every smoking room or will it be sufficient to perform one exemplary test?
It would be great if you could give me your opinion on this issue.
Many Thanks!
Oliver, I believe that each room needs to be tested—better quality control in terms of construction practices.
Combine smoking room exhaust with restroom exhaust
Sometimes it seams to be easier to combine the air duct system of the exhaust system of a restroom to that of a smoking room. In my oppinion there is no problem to match the requirement on the ventilation, if the system exhausts directly to outdoors.
I hope I'm right.
Hello,
as my question above is not answered yet, I have an additional Question.
Within a CS-Project the owner is not willing to provide public smoking rooms. Furthermore there is no possibility to provide onsite outdoor smoking areas at a suitable position (25 ft). Some of the tenants decided to build their own smoking rooms some didn’t.
Is there a responsibility for building owners to provide designated smoking areas onsite in CS-Projects?
Thank you for your answers.
Ralf
Ralf, based on the credit requirements it seems that if the exhaust from the smoking room meets the required pressure, it's okay to combined the exhaust with other rooms.
For your other question, building owners must either prohibit smoking, or if smoking will be allowed in designated places, the requirements outlined in the credit language must be followed, even if it's the tenant that builds the room. Make sense?
Thanks Tristan. In my oppinion that makes sense.
Minimum distance between smoking room exhaust and windows
Hello,
Under option 2 of this credit, the LEED Guidance states that: "At a minimum, the smoking room must be directly exhausted to the outdoors, away from air intakes and building entry paths , with no recirculation of ETSEnvironmental tobacco smoke (ETS), or secondhand smoke, consists of airborne particles emitted from the burning end of cigarettes, pipes, and cigars, and is exhaled by smokers. These particles contain about 4,000 compounds, up to 50 of which are known to cause cancer. contaning air to non smoking areas".
However the guidance does not specify the min distance required between the air intakes and the exhaust. Should we assume it's 25 feet (just like min distance between on-property smoking and air intakes/windows). What if the exhausted air is well filtered before exiting the building ?
Many thanks,
I would assume it's at least 25 feet, but if you want it to be closer, perhaps you could make a case for it in some fashion. I think this would be difficult, though.
High Residential Options
I am working on a high rise building with 22 stories. Is that eligible for choosing: Option 1- All Project - No Smoking in Buiding? Thanks.
Yes, definitely. Make sure to provide plenty of signage to prevent smoking in the building and near entrances, including any balconies.
Thanks Mr.Roberts. ...
I am sorry to say the building type, it is a residential project with individuale family unit in each floor. What about that?
You can earn the credit this way, just make sure that smoking is truly prohibited and that occupants will clearly understand that they can't smoke in their individual units.
Thanks Tristan. That makes sense.
