Web: Smokefree.ne.gov E-mail: smokefree@dhhs.ne.gov Phone: 402-471-8320 Indoor/Outdoor Areas Indoor area defined: “an area enclosed by a floor, a ceiling, and walls on all sides that are continuous and solid except for closeable entry and exit doors and windows and in which less than twenty percent of the total wall area is permanently open to the outdoors.” So if doesn’t meet definition of indoor area, then it is an outdoor area.

Only the first 8 feet of wall height are used in the Total Wall Square Footage (TWSF) calculation. The wall is completely enclosed, with no open area to the outdoors.

This entire wall is open to the outdoors, but the opening is partially blocked by 0.5 inch thick iron bars spaced evenly 6 inches apart. The entire open area, including that above 8 feet tall, is included in the Permanent Open Space Present (POSP) calculation.

Measuring Permanent Open Space Present (POSP) 10 ft high X 10 ft long = 100 sq. ft. total Subtract wrought iron bars 0.042 feet X 10 ft tall X 20 bars = 8.4 sq. ft. NOTE: bar width = 0.5 inches which equals 0.042 feet Bar spacing = 6 inches apart is 2 per foot POSP = 100 sq. ft. – 8.4 sq. ft. = 91.6 sq. ft.
