Can a smoking room be regarded as regulary occupied space?

Noriko, I would not count a smoking room as regularly occupied space—I would consider smoking more of a leisure activity, not study, work, or "other focused activities."

Initially i would go with Tristan and say that the smoking room would not be considered regularly occuppied. It is similar to a break room, which can be excluded.

However, you are providing windows for the space, and if the design intent was to provide occupants a space where they could smoke and enjoy views and daylight, then include in your calculations.

I don;t think a reviewer would question your decision either way with this one as long as the inclusion of thsi space determines credit achievement or not.

It is my understanding that break rooms are explicitly called out as non-regularly occupied and MUST be excluded. This is a break room. Many break rooms are provided with views and daylight and this does not change their classification as regularly occupied or not. I would caution using this as ROS. If you do, I would include a detailed narrative of your argument for it and please, report back here on how it went!

As long as you are consistent with the inclusion and exclusion of spaces they should not be any issues. I've never had any issues when including non-regularly occupied spaces in the calculations. I have not read that you MUST not include these spaces. If you are consistent and providing views and daylight to more spaces then required, you are going above the intent and requirements in my opinion. I don;t a reviewer would question this, as long as you are consistent.

I've always wondered why break rooms have been allowed to be excluded from the calculations. Here is a space that is provided to workers to rest or eat lunch so why wouldn't you provide them daylight and views. This would especially be significant in buildings where workers live in cubicle land and may not have any relevant eye relief from their computer screens except when on break.

I agree. I think it's strange that break rooms are not considered in the daylight calculations, but it does say that regularly occupied spaces are where people are working. And, I guess if you are working in an office that has daylight and views, you don't necessarily need daylight and views in your break room. Still, it seems counter intuitive.

I see what you are saying about including non-regularly occupied spaces. It is a good argument. Glad to hear that you have not had issues with it.
