We have a project where the hallways are pressurized to provide ventilation air thru door undercuts. In V3, there was a foot note which mentioned that for doors leading to pressurized hallways, weather stripping may not be required provided that the positive differential pressure is demonstrated as in case 1, Option 2. I don't see anything similar in V4. And if you weatherstrip the door to hallway, then required ventilation air supply will be at stake. Is anyone facing similar issues? Or does that mean that per v4, you cannot have door undercuts for ventilation?

Hi Judhajit,
According to the Reference Guide weather-stripping must be placed on all doors that lead to common space hallways, IF smoking is allowed in the units. I don't believe there is a workaround for this requirement. So, in terms of ventilation, it would mean that the unit would need to supply the ventilation air through different means. I do not have specific project experience to speak to this, nor are there any LEED Interpretations that speak to this issue (yet), but this would be my guess from interpreting the Reference Guide.
