Use the rough framed opening areas for doors. The glazing area Is derived by multiplying a constant <br />value (A 6) by the sum of the conditioned floor areas(Don't Include unheated attached garages, etc). <br />Page 2, Proposed Dwelling Calculation Compute areas using outer Surfaces for walls, callings, and floors. Use the <br />rough framed opening areas for doors and glazing. Since there are only four boxes on the form for glazing, combine <br />the areas of units with the same Uo value Into a single entry.
