• Prohibiting smoking on private residential balconies is a best practice for protecting nearby nonsmoking units and balconies from ETS infiltration. Consider prohibiting smoking on balconies in lease agreements.

Exclusions The enforcement of no-smoking policies does not extend to areas within residential healthcare projects, such as long-term care facilities, where residents may have a clinical need to smoke.

This prerequisite is not intended to prohibit or deter indigenous or other cultural ceremonial practices (e.g., smudging) which may include the combustion of tobacco and other ceremonial materials. LEED projects that accommodate cultural ceremonial practices may still pursue this prerequisite.

NO SMOKING SIGNAGE

The project team determines the placement and design of signage, allowing for flexibility to address site-specific considerations.

When communicating a no smoking policy, use signage that includes illustrations, photographs, or clear and concise wording. Consider using explicit language such as “No smoking allowed within x feet” or “Smoking is allowed in designated smoking areas only”. Signs should clearly indicate the designated smoking areas.

Prohibit Vehicle Idling

Vehicle idling is prohibited to minimize the likelihood of vehicle exhaust entering the building and to provide better air quality on site and for the neighboring community. An idling vehicle emits harmful chemicals and gases into the air. Exposure to these chemicals can aggravate asthma, allergies, and cardiovascular and respiratory diseases. Note that some cities, campuses, and other institutions may already have vehicle idling policies in place as part of their efforts to reduce emissions.

A vehicle idling policy is a set of guidelines designed to minimize the unnecessary running of vehicle engines while stationary. Such a policy typically prohibits idling beyond a specified duration, except in certain situations where exceptions may apply. For example, exceptions might be allowed for cold weather conditions where engine idling is necessary to maintain vehicle performance or occupant comfort, during emergency or safety situations, or for vehicles with specific operational needs, such as refrigeration trucks or vehicles running specialized
