[1] DB/WB ratio is the ratio of dry-bulb to wet-bulb temperature at the cooling design-day conditions. It is intended as a relative indicator of a climate's humidity during the cooling season. DB/WB ratio has been rounded to 2 decimal places for the purpose of this report.

[2] For “duct factor” a value of 0 implies that heating is never needed, thus all duct losses are assigned to cooling. A value of 1 implies that cooling is never needed, thus all duct losses are assigned to heating. Duct Factor has been rounded to 3 decimal places for the purpose of this report.
