The calculations on Ihe lower part ot this <br />page may be ignored if 6elow grade wall (nsulation will eAher be R19 on the interior or R10 exterior, or A the <br />basemenl will not be a habitable space and unhealed, and the floor above is insulated. <br />Page 2, Base Case Dwelling Calculetlon Compute areas using outer surfaces tor walls, ceilings (less skylights), <br />and Iloors. Uso Ihe rough tramed opening areas lor doors. The glazing area is derived by multiplying a constant <br />value (.15) by Ihe sum of tho condilioned floor areas(Don't include unheated attached garages, elc). <br />Page 2, Proposed Dwelling Calculation Compule areas using outer surtaces for walls, ceilings, and tloors. Use the <br />rough Iramed opening areas for doors and glazing. Since there are only four boxes on the lorm lor glazing, combine <br />the areas of units with ihe same Uo vciue into a single entry.
