The calculations on the lower part of this page may be <br /> ignored if below grade wall insulation will either be R-19 on the interior or R-10 on the exterior or if the basement will not <br /> be heated or a habitable space, and the floor above is insulated. <br /> Page 2,Target Dwelling Calculation. Compute areas using outer surfaces for walls, ceilings(less skylights), and floors. � <br /> Use the rough-framed opening areas for doors and giazing. WSEC Chapter 10 default vaiues must be used for all walls, i <br /> ceiiings, floors, untested doors/glazing, and to determine below-grade wall/slab UA'. The Target glazing area is 15°/a of � <br /> the total heated floor area. , <br /> Page 2,Proposed Dwelling Calculation. Compute areas using outer surfaces for wall, ceilings, and floors.

Exclude door and glezing areas and insert only i <br /> the concrete wall area fnto the designated boxes for both Target and Proposed heat loaa. � <br /> 3. Find the appropriate wall depths in Table 1 and insert the corrcsponding wall values into the Target box(es). Multiply { <br /> the wrtespanding wall U•factor by the area derived in Step pL 1 <br /> ♦. Measure the perimeter distance in linear feet for each slab under a wall with a different Table 1 depth.
