NC-2009 IEQp2: Environmental Tobacco Smoke (ETS) Control

  • Multi-rating system IEQp2 Credit Requirements Diagram
  • 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

    Do I have to provide a designated smoking area?

    No—this is optional.

    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.

    How can I prohibit smoking 25 feet from the entrance of my project when it is a zero lot line and its entrance abuts a public sidewalk?

    Although projects may not have complete control over the public space that surrounds their building, at minimum, provide adequate signage that communicates smoking is prohibited 25 feet from the entrance. Signage can help deter people from standing outside of the door to smoke.

    Additionally, do not have designated smoking areas or ash trays outside the entrance to further discourage smoking by the entrance. For documentation purposes, provide a photo or plan indicating where the signage will be installed, and note any additional efforts (such as no ashtray by entrance or security that may enforce the no smoking within 25 feet rule).

    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.

    Does this prerequisite apply to e-cigarettes?

    Yes. As of 7/1/2014, with LEED InterpretationLEED Interpretations are official answers to technical inquiries about implementing LEED on a project. They help people understand how their projects can meet LEED requirements and provide clarity on existing options. LEED Interpretations are to be used by any project certifying under an applicable rating system. All project teams are required to adhere to all LEED Interpretations posted before their registration date. This also applies to other addenda. Adherence to rulings posted after a project registers is optional, but strongly encouraged. LEED Interpretations are published in a searchable database at usgbc.org. #10388, the environmental tobacco smoke (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.) prerequisite applies to e-cigarettes as well as conventional cigarettes. USGBC cites the World Health Organization, stating that "e-cigarettes should be prohibited anywhere where the use of conventional cigarettes is prohibited."

Legend

  • Best Practices
  • Gotcha
  • Action Steps
  • Cost Tip

Pre-Design

Expand All

  • Establish the smoking policies for interior spaces and exterior spaces, including balconies, by working with the building owner. Many municipal codes do not permit smoking in public buildings, so banning smoking (Option 1) may be the only legal option in some cases.


  • Additional consultant costs may arise from documentation and testing processes, if projects choose to have interior designated smoking areas.


  • For residential applications, adopting a no-smoking policy in Homeowners Association policies has been a good strategy for reducing ETS transfer between units. In past versions of LEED, this type of policy has also been sufficient to demonstrate compliance with the prerequisite requirements. However, because of changes to the credit language and LEED Online credit form, it is unclear if this strategy would be accepted as compliant without conducting blower door testing as well. Any multi-family project pursuing this type of strategy should be prepared to submit a CIR to confirm that the approach will be acceptable to the GBCI review team.


  • Air sealing between units is recommended for several reasons, even if smoking is banned.  In multifamily buildings and hotels it is common for occupants to smoke inside their units despite nonsmoking policies. Without air sealing between units, other occupants may be exposed to secondhand smoke and odors. Air sealing between units also improves energy performance, particularly in high rises subject to the stack effect, in which warm, buoyant air rises upward, leading to thermal losses and ventilation problems. Acoustic privacy is also improved by air sealing, and air sealing also reduces pathways for vermin.


  • High quality construction using air sealing can be marketed as a building feature for multi-unit construction, and has been shown to attract premium rents and sales prices.


  • Banning smoking on private balconies is necessary if they are within 25 feet of a neighbor’s operable window or another building opening, even if smoking is allowed inside the unit. Multifamily tenants may be unhappy with these rules, so owners should carefully consider their policies, the needs and habits of their tenants, and the design and location of balconies and openings.

Schematic Design

Expand All

  • If allowing smoking in some units, clustering those rooms on one floor can keep the need for special air sealing and hallway pressurization strategies (which can be used in lieu of weatherstripping) relatively contained.


  • Incorporate smoking-related requirements into the commissioning documentation, including the Owner’s Project Requirements and the Basis of Design for EAp1: Fundamental Commissioning.


  • Designate the location of outdoor smoking areas, if any, on design drawings. Ensure that these areas are appropriately removed from building windows, ventilation opens, and entrances, and entrance paths.

Design Development

Expand All

  • The mechanical engineer ensures that the HVAC design meets the exhaust and pressure levels of the LEED requirements. Also ensure that all units will receive adequate fresh air. A certain amount of air infiltration may be assumed, but the careful air-sealing associated with this credit may reduce the infiltration below expected levels. Ensure that mechanical systems, operable windows, or a combination, are able to provide enough ventilation. Make sure that pressure differences between the hallway and unit are enough to prevent cross contamination, but not so much that doors slam doors shut or are difficult to operate.


  • Operating energy use may be increased by maintaining the negative pressure requirements for interior designated smoking rooms. Designated smoking rooms in commercial properties can also add upfront costs associated with construction and design, added ventilation loads, and air sealing and deck-to-deck partitions. On the other hand, increased air sealing can decrease energy costs and increase rents, as noted earlier.


  • Eliminating smoking in a building costs virtually nothing and is the simplest way to control environmental tobacco smoke (ETS).  Possible associated costs would be the cost of signage indicating that the building is non-smoking and the development of a nonsmoking policy. Benefits include occupant health and productivity, and reduced cleaning and maintenance.

Construction Documents

Expand All

  • In non-residential construction when smoking will be banned (Case 1, Option 1), incorporate smoking-related signage into plans and construction specifications. Fill out LEED Credit Form and upload all supporting documentation to LEED Online.


  • If smoking is to be allowed in certain areas (Case 1, Option 2 and Case 2), integrate deck-to-deck partitions and weatherstripping or pressurization into plans and construction document specifications.


  • Identify potential air leakage points in design and construction plans early. Common examples of areas where leakage occur include electrical boxes, air registers, window frames, and where walls meet the floor.


  • Ask a blower-door or air-barrier expert to review construction documents and shop drawings prior to the actual testing to ensure that problem areas, including deck to deck partitions, are likely to be sealed according to specifications.


  • Ensure that the blower door test is included in the contractor’s or any other responsible parties’ scope of work.

Construction

Expand All

  • If smoking is to be allowed in certain areas (Case 1, Option 2 and Case 2), fill out LEED template and upload all supporting documentation to LEED Online.


  • A no-smoking policy for construction workers is not required for this prerequisite, but is a good practice, especially after the enclosure is installed, and will help achieve IEQc3.1: Construction IAQ Management


  • Orient all subcontractors to air-sealing goals and quality-control practices.


  • The contractor schedules any necessary air pressure or blower door tests in their proper sequence. Testing occurs at various construction phases and ideally with a test unit to identify any leakages and opportunities for improvement in other units.


  • Involve an experienced blower-door testing agent in visual inspections before drywall is installed in any of the units. This will ensure that problem areas are addressed while they are still easily accessible. Also bring the blower-door expert in for early testing, once the drywall is installed, but before painting, finish materials, and appliances are installed. This will point out penetrations that need to be sealed between units and allow contractors to address those penetrations in the remaining units to ensure that all units meet the standard.


  • Conduct blower door tests, which in multifamily and hotel applications typically require a sampling of one out of every seven units. See the Home Energy Rating System program (link) for details on sampling rates. For any spaces that do not pass the blower door pressure test, correct any potential problems and retest, or another space has to be tested until 100 percent of the requisite number of spaces have successfully passed.


  • The cost of a blower door test will vary by region and project, but expect an average of  $500–$800 per test.

Operations & Maintenance

Expand All

  • Uphold and enforce the nonsmoking policy, if applicable. Nonsmoking policies can be enforced with documented building policies, and building signage.


  • Additional policies to support a nonsmoking building may include providing smokers with alternatives such as outdoor smoking areas, giving employees incentives to quit smoking, and if smoking is permitted in parts of the building, developing a phase-out plan.


  • Nonsmoking policies can be implemented with homeowners association policies, building signage, and other means of communicating with occupants.


  • Additional costs from maintaining designated smoking areas within a building may include more frequent and more rigorous cleaning, disposal of ashes and butts, and frequent change-out of  ventilation system filters. Light fixtures and finishes may also need to be replaced more frequently in designated smoking areas.

    IEQ Prerequisite 2: Environmental Tobacco Smoke (ETS) Control

    Required

    Intent

    To prevent or minimize exposure of building occupants, indoor surfaces and ventilation air distribution systems to environmental tobacco smoke (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.).

    Requirements

    Option 1

    Prohibit smoking in the building.

    Prohibit on-property smoking within 25 feet of entries, outdoor air intakes and operable windows. Provide signage to allow smoking in designated areas, prohibit smoking in designated areas or prohibit smoking on the entire property.

    OR

    Option 2

    CASE 1. Non-Residential Projects

    Prohibit smoking in the building except in designated smoking areas.

    Prohibit on-property smoking within 25 feet of entries, outdoor air intakes and operable windows. Provide signage to allow smoking in designated areas, prohibit smoking in designated areas or prohibit smoking on the entire property.

    Provide designated smoking rooms designed to contain, capture and remove 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. from the building. 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. Operate exhaust sufficient to create a negative pressure differential 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 from entries, outdoor air intakes and operable windows opening to common areas.

    Prohibit on-property smoking within 25 feet of entries, outdoor air intakes and operable windows. Provide signage to allow smoking in designated areas, prohibit smoking in designated areas or prohibit smoking on the entire property.

    Weather-strip all exterior doors and operable windows in the residential units to minimize leakage from outdoors.

    Minimize uncontrolled pathways for ETS transfer between individual residential units by sealing penetrations in walls, ceilings and floors in the residential units and by sealing vertical chases adjacent to the units. Weather-strip all doors in the residential units leading to common hallways to minimize air leakage into the hallway1.

    Demonstrate acceptable sealing of residential units by 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. conducted in accordance with ANSI/ASTMVoluntary standards development organization which creates source technical standards for materials, products, systems, and services-E779-03, Standard Test Method for Determining Air Leakage RateThe speed at which an appliance loses refrigerant, measured between refrigerant charges or over 12 months, whichever is shorter.

By Fan Pressurization. Use the progressive sampling methodology defined in Chapter 4 (Compliance Through Quality Construction) of the Residential Manual for Compliance with California’s 2001 Energy Efficiency Standards. Residential units must demonstrate less than 1.25 square inches leakage area per 100 square feet of enclosure area (i.e., sum of all wall, ceiling and floor areas). Projects outside the U.S. may use a local equivalent to ANSI/ASTM-Control E779-03, Standard Test Method for Determining Air Leakage Rate By Fan Pressurization.

    Potential Technologies & Strategies

    Prohibit smoking in commercial buildings or effectively control the ventilation air in smoking rooms. For residential buildings, prohibit smoking in common areas and design building envelope and systems to minimize 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.

    FOOTNOTE

    1 If the common hallways are pressurized with respect to the residential units then doors in the residential units leading to the common hallways need not be weather-stripped provided that the positive differential pressure is demonstrated as in Option 2, Case 1 above, considering the residential unit as the smoking room.

Yes, alarmed exits are usually connected to the fire alarm / life safety. When a building occupant uses that exit and there is not a fire alarm going off, the door rings alerting people to a problem.

David, your review comments are consistent with what I've always understood to be the case. Can you alarm some of your exits? They want to ensure that people don't come and go through those doors to smoke. If there is a short cut, people will find it and exploit it.

Smoking room - separate AHU system?

This is an office building. The designer is proposing to use a single exaust system for one smoking room and other smoke free rooms. It is a 100% outdoor air system with a plate heat recovery, so there will be no 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. recirculation at all.
The IEQp2 requirements Option 2, Case 1 doesn't require a separate system. But in the implementation section it says "install separate ventilation systems must be installed" (seems to be an erroneous wording here).
Do we need a separate, standalone exhaust system for indoor smoking rooms? I think no and the proposed design is ok, as it fulfills the requirements and the intent of the prerequisite, as there will be no ETS contamination outside the smoking room.
Thanks

Worst condition?

From the requirements: "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."

It seems to me that having doors open is the worst case, not doors closed. Any opinions on that?

Non-smoking campus - are exterior signs required?

My project is on a college campus that is non-smoking on the entire campus, there are no areas with permitted smoking. The streets themselves are university property, not public streets.

If everything and everywhere is non-smoking, and there are "no smoking/tobacco inside and out" on exterior doors (for this building and every other building on campus), would there be any requirement to place free-standing signs on the edges of the site? Or are the signs on the doors enough?

The campus is willing to put up free-standing sign in areas that expercience difficulties with tobacco use, but I don't want to put up signs by default if I don't have to. Thanks!

There is no need to place free standing sings if you have signs on the building itself stating it is prohibited to smoke within 25 feet of the building.

But there is NO smoking on the entire campus, anywhere. A sign with the language no smoking "within 25 feet of the building" would go against their more stringent policy, and would imply that the students/visitors/professors CAN smoke at 26, 27, 28+ feet, etc. - which they definitely are not.

Would "no smoking/tobacco inside and out" and "tobacco free on entire campus" signs on the building actually not meet the requirements, simply because the sign doesn't mention 25'?

Hi Renee,
Using language that indicates there is no smoking allowed on campus is perfectly acceptable - it does not specifically have to state 25.' We have used that approach on many campus projects. The language we have typically seen is "Tobacco Free Campus" or "This is a Nonsmoking Campus"

THANK YOU!!! That is what I was hoping for. The university's policy also clearly states that signs (wall-mounted or free-standing) can be added wherever problems with adherance may arise, so hopefully that should satisfy any reviewer that thinks there should be more signs. The client will be very happy.

Site plan without smoking areas

Hello LEEDusers!
We are supposed to upload a site plan/map that shows the location of the designated outdoor smoking /nonsmoking areas. Since we have no smoking areas we upload a site plan highlighting only the 25ft distance from the building and position of all signs communicating the 25 ft rule. However, the building's facade is very close to the LEEDboundary. Shall we mark the non-smoking area beyond the LEEDboundary in the site plan or keep it within?

Hi Jiri,
I have done dozens of projects in WA where smoking is not allowed in most places. In all cases, I have simply uploaded a statement that we have no designated smoking areas. It's a bit frustrating that item is a mandatory upload. Despite many other issues with reviewers about smoking sign verbiage and locations, no one has ever commented on that simple statement.

"Vertical chase" meaning

The term "vertical chase" is present on the definition of "differential air pressureThe difference in air pressure between two spaces, potentially leading, in the case of a pressure difference, to the migration of contaminants from one space to another. When using a designated smoking room ror environmental tobacco smoke control, you may need to test the differential air 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. The testing will be conducted with each space configured for worst case conditions of transport of air from the smoking rooms to adjacent spaces with the smoking rooms' doors closed to the adjacent spaces. The test can be conducted by a mechanical engineer. The test should involve 15 minutes of measurement, with a minimum of one measurement every 10 seconds. With the doors to the smoking room closed, operate exhaust sufficient to create a negative pressure with respect to the adjacent spaces of at least an average of 5 Pa (0.02 inches of water gauge) and with a minimum of 1 Pa (0.004 inches of water gauge).". Does "vertical chase" refers to pipe shafts adjacent to the room or to the ceiling plenum?

The definition of differential air pressure is copied below:

I realized that vertical chase does not refer to plenum, as I asked above.

I have a follow up question though: does this prerequisite require that a differential pressure measurement is conducted for each adjacent space or vertical chase that HAS a door to the smoking room?

e-cigarettes just like regular cigarettes

USGBC has just issued a LEED InterpretationLEED Interpretations are official answers to technical inquiries about implementing LEED on a project. They help people understand how their projects can meet LEED requirements and provide clarity on existing options. LEED Interpretations are to be used by any project certifying under an applicable rating system. All project teams are required to adhere to all LEED Interpretations posted before their registration date. This also applies to other addenda. Adherence to rulings posted after a project registers is optional, but strongly encouraged. LEED Interpretations are published in a searchable database at usgbc.org. clarifying that e-cigarettes should be considered the same as conventional cigarettes for the purpose of this prerequisite. This follows World Health Organization recommendations. See LEED Interpretation #10388 for the exact language.

Alternative compliance with ETS prohibition

We would like to certify a multifamily Residential building. Smoking will be prohibited within the LEED Boundary in common areas, but in some public areas (closer than 25 feet from main entrance) we cannot prohibit smoking because this would contrast local regulations.

The apartments are equipped of mechanical ventilation system (the air intake is on roof, far from any 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.

Entrance doors will be equipped with self-closing mechanisms, in order to guarantee that outdoor smoke will be kept out. External windows are equipped with sealings which guarantee air tightness. Blower door tests will be performed according to the Protocol.

Are these systems sufficient to comply with prerequisite requirements?

Blower door test for 1 in 7 of each room model

Hi,
I was wondering if the v2.2 option (HERS methodology) would still apply for v2009 in regards to 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. and number of units that must be tested. I read once that you could test only 1 in 7 similar units (same layout).
My project is both a hotel and residential building, and there are different types of apartments and hotel rooms which are obviously repeated throughout the building.
Just as an example, if I had 3 different types of hotel rooms with 10 units each, I would have to test only a total of six units.
Can we still do this and comply with the prerequisite requirements?
If anyone can come up with the official source of this info I recall I'd be glad to hear it.
Thank you.

Performing Arts Building may have periodic smoking on stage

Hello,
I am working on a performing arts building that has a no-smoking policy for the interior and within 25' of the building. However, there may be occasions where scripts warrant smoking and actors will smoke on stage.

Glen Phillips Director of Sustainable Education, GreenCE, Inc. Jun 18 2014 Guest 409 Thumbs Up

As a non-answer, I would suggest maintaining the no smoking policy in full, and consider the use of prop cigarettes when they are called for by the script. I did a quick search online, and found several of these prop cigarettes that are designed specifically to look real on stage.

Regarding the blower door based approach, it would probably require designating the entire theater space (seating and performance areas) as the smoking area, which although the owner would be free to disallow smoking by the audience, would be an odd distinction. Additionally, and depending on climate zoneOne of five climatically distinct areas, defined by long-term weather conditions which affect the heating and cooling loads in buildings. The zones were determined according to the 45-year average (1931-1975) of the annual heating and cooling degree-days (base 65 degrees Fahrenheit). An individual building was assigned to a climate zone according to the 45-year average annual degree-days for its National Oceanic and Atmospheric Administration (NOAA) Division., there could be a huge energy penalty associated with the direct exhaust requirement for designated smoking areas of such a large volume.

All that said, and although it was (I think) under v2.2, I believe there was a Las Vegas casino project that successfully met this prerequisite, while allowing smoking in the gambling area and having no physical barrier between the smoking area and the lobby. My guess is that whatever strategy (read: loophole) they used for this has long since been closed, but if you are hard pressed for a way to approach this, it could be worth a look.

I think the loophole was relative to the LEED project boundary. They excluded the smoking area from the LEED project. Now with the MPRs since LEED 2009 you need to include the whole building and can't gerrymander.

I think Glen's answer was spot-on with regard to prop cigarettes. I don't think audiences these days are craving real cigarette smoke from their on-stage actors, either. A prop that doesn't quite smell like the real thing will be appreciated.

My city has an ordinance that there is no smoking within 20' of outside doors on City property. This is a City-owned facility and that is the rule that is enforced by management. If the no smoking signs say 20 feet instead of 25 feet, will that be accepted, if I also upload a copy of the City's ordinance?

Location of the sign "No smoking within 25' of building"

This question was posted a few years ago but I felt the response was ambiguous so I'd like to revisit.

Is it sufficient to have a "No smoking within 25' of building" sign posted at the building entrances or do they need to be located at the perimeter of the non-smoking area?

Michelle Rosenberger Partner, ArchEcology, LLC Jun 05 2014 LEEDuser Member 5515 Thumbs Up

Hi Allison,
I can understand why you'd post this. Even though there are ZERO requirements with respect to how many signs and what they should say specifically, we continue to get review comments that say we are not demonstrating "sufficient" signage to communicate "reasonably" with occupants.

We are in a state where smoking is prohibited in all public places and commercial buildings and most residential buildings are non-smoking also. Not a lot of communication is required for us to know we can't smoke. I understand that not all states are this way, and the LEED requirements need to be acknowledged. However, guessing what is sufficient and reasonable (obviously subjective terms) on a Prerequisite is incredibly frustrating.

It would be great if the USGBC would make these requirements definitive.

In the interim, we have been using the entire phrase "no smoking within 25' of entries, outdoor intakes and operable windows" and advising clients to post at all primary entrances and at exterior amenity spaces. We hope this will be sufficient and reasonable for reviewers.

posted signage

we are building a campus of buildings (non-school) that has a non smoking policy except in one designated outside area. In order to get into the campus you have to pass through security which has a posted no smoking sign at the entrance. The designated smoking area within the campus has a designated smoking area sign. Do the other buildings in the campus need to have posted no smoking signs and if so, do they need to clearly state "no smoking within 25 feet of the building except in designated outdoor smoking areas"? or can they just have 'no smoking' with the symbol?

Smoking zone - away from pedestrian traffic

We have recently received a remark from a review that our designated smoking zone is not compliant since it is not 25 feet away from concentrations of building occupants and pedestrian traffic. The reference guide does not include this requirement for this prerequisite but it is mentioned in the implementation strategy. Not meeting a minimum distance (not mentioned) away from public concentrations of building occupants and pedestrian traffic should not be an issue to meet the requirement of this prerequisite.

Has anyone successfully pursued Option 2 Case 2 (blower door testing) for type 1B multi-family project?

David Posada Sustainability Manager, SS TAG member, GBD Architects Apr 14 2014 LEEDuser Expert 17838 Thumbs Up

Jeremy,
We have used blower door testing on several projects to verify that residential units were air sealed and tobacco smoke in one unit would not travel to adjacent units.

This not easy to achieve in projects with light gauge metal framing. Wood framed buildings are a bit easier, but can still require additional diligence to seal penetrations. While wood studs can sometimes help create an air barrier between one stud bayA bay is a component of a standard, rectilinear building design. It is the open area defined by a building element such as columns or a window. Typically, there are multiple identical bays in succession. and another, metal studs and joist all have openings for routing wires, etc.

The effort is worthwhile: complaints from smoke odors passing between units can and do happen and are hard to fix. The air sealing also contributes to acoustic (and thermal) performance.

Some typical problem spots: pocket doors, soffits, can lights, wet walls with many penetrations, bundles of wires, and tub/shower enclosures that don’t have wall board behind them. Common walls between dwelling units may have staggered studs, or RC channel like you mention, so electrical outlets facing one unit could have an air pathway to an outlet facing the other unit even if they are in separate stud bays. In some cases “putty packs” to seal outlets in common walls might be useful.

One good reference is the EPA Thermal Bypass Checklist Guide used by LEED Homes, HERS raters and others: http://www.energystar.gov/ia/partners/bldrs_lenders_raters/downloads/TBC...
One approach is to create a continuous air barrier with drywall at the common wall between units. This layer of drywall needs a small gap in the framing so is not interrupted by the interior walls within a dwelling unit that are perpendicular to that common wall. Since framing will usually be done before any drywall gets hung, the goal is to leave a gap between the common wall framing and the interior wall framing so that drywall can slide through that gap and be hung to create one continuous plane at the common wall. It’s not common practice, and requires coordination.

Expect the first project to have challenges. Consider finishing a sample unit before the others so you can do a pre-test and correct any issues. This can also provide a mock-up for orienting all the trades that can impact the air barrier.

Hope that helps!

Unfortunately there is only so much control the project can have in this instance. At minimum, you should show that adequate signage communicating smoking is prohibited 25 feet from the entrance has been installed or planned. Usually a photo, and or a plan indicating where signage will go is sufficient. While you can't corner off a 25 foot space in the zero lot line case, you can deter people from standing outside of the door to smoke. In this case, you also do not want to have a designated smoking area, i.e. an ash tray, and could state that in your documentation to strengthen the efforts the project has made to curb smoking.

But there may be good reason to use the updated standard and if you wanted to do that I would submit a project specific CIRCredit Interpretation Ruling.

Residential Units - Pressure Testing

The rooms are served ventilation via a central system with under-door cuts into each unit, and we intend to show compliance via design for proper positive pressure differential from the hallways to the space (in lieu of weatherstripping).

Will we also need to complete pressure testing for these units, per the non-residential requirement? Or will the mechanical design documentation suffice?

I don't think that any specific filtration is required for a smoking zone's exhaust system for the LEED prerequisite.

ETS Signage Requirements

We submitted a project for review on a campus which prohibits smoking both in the building and the entire campus site. We provided the campus policy as well the campus poster indicating the policy. Our review comments were: '...the drawings / photographs confirming signage system communicating the exterior smoking policy have not been provided as required. Note that a campus policy is insufficient to achieve this prerequisite. Signage must be provided to communicate the building smoking policy to all occupants, visitors, and passersby, including those individuals who may be unfamiliar with the policy.' Since smoking is prohibited everywhere on the campus, will no-smoking signage on the building entry doors satisfy this requirement?

USGBC typically requires actual photographs of the signage. It isn't enough to indicate where they are located on plans; rather, documentation should include detail drawings of the signs (if not yet constructed) or photographs of the actual signage, to demonstrate that they meet all requirements.

The reason they won't allow an all-campus policy to meet the requirement is that if someone were to visit the campus (non-student or staff), they would need to be informed visually of the smoking restrictions.

As far as I know the timing of blower door tests is not specified by the referenced standards, and is not specified by the LEED language, so you could perform it at the most reasonable time for the project, in accordance with the credit intent. 

My concern here would be that installation of nonmovable furniture could cause wall or other penetrations that would allow leakage. I would take steps to avoid this and/or hold off on testing.

1- As what stated before, can the Project's owner deliever the signatory statement or it has to be the building's managaer who has to provide this?

2-In signage, it has to state clearly the 25 ft requierement of just by showing the no-smoking signs located in the building is enough?

Thank you

Daniel, the most recent version of this form that I looked at called for owner/agent signature. 

I don't understand your second question—can you try rephrasing?

No Smoking Signs

Where do the no smoking signs need to be located? All exterior doors? Only ingress doors?

Thanks,
Crissy

Crissy, I would not think it necessary to post signs at doors that will not be used for ingress.
