*Based on design conditions of outdoor 20_F/ ---7_C dry bulb, 80% RH; indoor 70_F/21_C dry bulb, 40% RH, and minimum moisture production from residen- tial operations for an absolute humidity difference of 0.0049 lb/hr.

NOTE:

Tight house is defined as being well insulated, having vapor barriers, tight storm doors and windows with weatherstripping, and having dampered fireplaces. Average house is defined as being insulated, having vapor barriers, loose storm door and windows and having dampered fireplace.
