The calculations on the lower pan oi this page may be ignored N below grade wail insulation will either be R19 on the interior or R10 exlerior, or if thie basement will not be a habitahle space and unheated, and the floor above is insulated. Page 2, Base Case Dwelling Celculatlon Compute areas using outer suAaces tor walls, ceil(ngs (less skylfghts), and iloors. Use the rough framed openfng areas tor doors.The glazing area fs derived by muitipiying a constant value (.15) by the sum o(the wnditioned iloor areas(Don't include unheated attached garages, etc). Page 2, Proposed Dwelling Calculatlon Compute areas using outer suKaces for walls,ceilings, and(loors. Use the rough framed opening areas(or doors and glazing. Since there are only tour boxes on the form tor glazing, combine the areas of units with the same Uo value into a single ent�. WSEC, Chapter 10, defauit values must be used tor all walls, ceilings, fioors, untested doors/giaziny, and to determine below-grade walVslab UA.
