The calculatfons on tha lower part of this <br />page may be ignored 'rf below grade wall insulation will efther be R19 on the interior or R10 exterior, or'rf the <br />basement will not be a habftable space and unheated, and the iloor above is insulated. <br />Page 2, Base Casa Dwefling Calculetlon Compute areas using outer surfaces forwalls, ceilings (less skylights), <br />and floors. Use the rough framed opening areas for doors. The glazing area is derived by multiplying a constant <br />value (.15) by the sum of the conditioned floor areas(Don't include unheated attached garages, etc). <br />Page 2, Proposedl Dwelling Caiculatlon Compute areas usfng auter surtaces forwalls, ceflfnns, _md floors.
