LEED ID+C: Retail | v1.0 pilot

Environmental tobacco smoke (ETS) control

EQp2 | Required

Intent

Prevent or minimize exposure of tenant space occupants, indoor surfaces and systems to Environmental Tobacco Smoke (ETS).

Requirements

Minimize exposure of non-smokers to ETS by one of the following options:

Option A: Locating tenant space in a building that prohibits smoking by all occupants and users and maintains any exterior designated smoking areas at least 25 feet away from entries, outdoor air intakes and operable windows,

OR

Option B: In buildings where smoking is permitted, confirming that smoking is prohibited in the portions of the tenant space not designated as a smoking space, in all other building areas served by the same HVAC system, and the common areas used by tenant’s occupants, and that there is no migration of ETS by either mechanical or natural ventilation from other areas of the building.

AND

If the tenant’s occupants are permitted to smoke, providing one or more designated smoking rooms designed to effectively contain, capture and remove ETS from the building. At a minimum, each smoking room must be directly exhausted to the outdoors with no recirculation of ETS-containing air to the nonsmoking area of a building, enclosed with impermeable deck-to-deck partitions and operated at a negative pressure compared to surrounding 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) when the doors to the smoking room are closed.

Performance of the smoking rooms differential air pressure shall be verified by conducting 15 minutes of measurement, with a minimum of one 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 rooms 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.

For projects located in a residential building that allows smoking

Please submit documentation demonstrating that there is no migration of ETS as described in the credit requirements. This might include documentation from the Commissioning Agent or Mechanical Engineer stating that the tenant space is served by a dedicated outside air supply system that provides the minimum fresh air to the HVAC system; that the shared walls the project and the residential units are sealed deck-to-deck partitions, that the HVAC units that condition the air maintain a constant positive pressure inside the space, and there is no smoking allowed in the tenant space.
