[Bldg-sim] 90.1-2010 question

[Nick Caton]

I have also taken those areas in the exceptions as the entire building's, though I'd agree it's not worded clearly enough to prevent various interpretations.  

I'm not an English major, but I think if you could find a grammar guru they'd be able to cite something to the following effect: When a sentence's subject and object is not made clear by any other means in the structure/word choice, the word closest to the verb is the object affected by that verb.

These exceptions to the mandated vestibule (varying by climate zone) seem generally logical to me.  While vestibules in many cases will save energy, at some point a vestibule of minimum dimensions becomes a significant fraction of cost and useable space for small buildings... Vestibules and other infiltration mitigation (revolving doors) cost money in and of themselves and probably generally do less for a tiny building relative to the savings to be had with larger buildings having heavier regular entry traffic.  That's not to say a vestibule is a BAD idea for small buildings - savings will be proportional to the entry traffic: a small McDonald's will get much more out of an entry vestibule than an equally-sized storage facility.

I vote: Buildings less than 1000 sq.ft. - but I wonder why they bother exempting such a small building///////

This is a question about 5.4.3.4, exception f) "Building entrances in buildings located in climate zone 5, 6, 7 or 8 that are less than
1000 ft2 in area."

Does this mean "building entrances that are less than 1000 ft2" or "buildings that are less than 1000 ft2."

Thanks for any insights.
