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

Smoke/acoustic seal around the door instead of weather seal

Residential units in the project have doors facing the corridors which in completely inside of the building as they are in a high-rise tower. 

 

The guide says "Weather-strip all doors in the residential units leading to common hallways to minimize air leakage into the hallway", but it is not a common practice to use weather strips for interior doors. Instead, as the doors are fire rated, fire/smoke seal are provided around the doors and auto-door bottom are at the bottom of the doors to seal for acoustic purpose. 

As the purpose of "weather-strip" for this credit is not for "weather" but for to completely seal around the doors, I think smoke/fire seal (gasket) and auto-door bottom do have the same function. 

 

I would like to seek you opinion and would like to see if any of you had the same conditions and accepted with fire/smoke seal by the USGBC reviewer. 

 

Thank you,
