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.

For Core and Shell projects, tenant guidelines should stipulate a non-smoking policy or extra care should be taken by the core and shell build-out to ensure interior designated smoking areas will be property sealed for future tenant uses.

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

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.

In projects with operable windows, occupants may not know when conditions are best for opening the windows. Implement a system so that occupants are informed of when to open and close the windows to achieve designed performance and optimal comfort.

A documented ventilation performance plan can help ensure that systems reach the expected ventilation thresholds.

Getting feedback on ventilation performance from occupants through surveys can help to identify potential problems that may become expensive if they go unnoticed.

Provide operations and maintenance personnel with manuals and educate them about any atypical maintenance requirements.

Test all dedicated building exhaust systems including chemical areas, bathroom, shower, kitchen, and parking exhaust systems to confirm proper fan speed, voltage, control sequences, and set points as applicable.

Monitor outdoor air delivery periodically to confirm that minimum ventilation rates are being maintained. Implement a maintenance program to ensure that mechanical system components are functioning properly over time.
