For SI: 1 cubic foot per minute = 0.47 L/s, 1 square foot =
				0.093m2, 1 pound per square inch = 6895 Pa, 1 inch
				water gauge = 1250 Pa.
a Values given by this table are for
				distribution systems, which must still meet all prescriptive requirements for
				duct and pipe system insulation and leakage.
b Entire system in conditioned space
				shall mean that no component of the distribution system, including the
				air-handler unit, is located outside of the conditioned space. All components
				must be located on the interior side of the thermal envelope (inside the
				insulation) and also inside of the air barrier. Refrigerant compressors and
				piping are allowed to be located outside.
c Zonal systems are systems where
				the heat source is located within each room. Systems shall be allowed to have
				forced airflow across a coil but shall not have any ducted airflow external to
				the manufacturer's air-handler enclosure. Hydronic systems do not
				qualify.
