I recently started a full reading of the 2009 IRC. In the past I have found that even though I know the code fairly well there will be things that will "bite" me because I missed them. So the last thing I do before falling asleep several nights a week is to read word for word the sections I don't know as well that might apply to what I would do and make notes on things I might miss. So each time I come up upon something I think is not clear, I will post it here as a question and revise the thread each time I have a new question to pose.
Under light and ventilation, "R303.1 Habitable rooms. All habitable rooms shall have an aggregate glazing area of not less than 8 percent of the floor area of such rooms. Natural ventilation shall be through windows, doors, louvers or other approved openings to the outdoor air. Such openings shall be provided with ready access or shall otherwise be readily controllable by the building occupants. The minimum openable area to the outdoors shall be 4 percent of the floor area being ventilated."
What is a "room" is it a habitable area (which is defined in the code) that is closed off from other areas by a door? We usually refer to a kitchen as a room and sometimes as a kitchen dining room but the kitchen frequentely will not have a window or any natural ventilation.
I know the exceptions with adjoining "rooms" and common walls ect. but here is my question: The code doesn't define a room so what is a room?
