401.2.1. Compliance software tools. Software tools used to demonstrate energy code
compliance that are deemed acceptable by the building official. The PNL program RES
Check is not acceptable for residential compliance.
Amend Section 402.1.1 Insulation and fenestration criteria. to read as follows:
402.1.1 Insulation and fenestration criteria. The building thermal envelope shall meet

compliance.
When compliance using Table 402.1.1 is demonstrated with a ceiling R-value ofR30 or
less, no more than 33% of the total projected ceiling area may be of cathedral type
construction (ceiling joist/roof rafter assembly) and the required insulation R-value may
be reduced to a minimum of R22 insulation when the remaining ceiling area insulation is

to all glazed fenestration.
c. R-5 shall be added to the required slab edge R-values for heated slabs.
d. The total R-value may be achieved with a combination of cavity insulation and
insulating sheathing that covers 100% of the exterior wall.
e. The wall insulation may be the sum of the two values where the first value is the
cavity insulation and the second value is insulating sheathing. The combination
of cavity insulation plus insulating sheathing may be used where structural
sheathing covers not more than 25% of the exterior wall area and insulating
sheathing is not required where structural sheathing is used. If structural
sheathing covers more than 25% of exterior wall area then the wall insulation
requirement may only be satisfied with the single insulation value.

envelope component criteria in Table 402.3.7 for the sub climate zone applicable to the
location. The U-factor of each individual fenestration product (windows, doors and
skylights) shall be used to calculate and area-weighted average fenestration product U-
factor for the addition, which shall not exceed the applicable listed values in Table
402.3.7. For additions, other than sumoom additions, the total area of fenestration
products shall not exceed 40 percent of the gross wall and roof area of the addition. The
R-values for opaque thermal envelope components shall be equal to or greater than the
applicable listed values in Table 402.3.7.
Conditioned sumoom additions shall maintain thermal isolation; shall not be used as
kitchens or sleeping rooms.

above the NAECA (National Appliance Energy Conservation Act)
Standard.
Add Section 501.3. Compliance software tools. to read asfollows:
Section 501.3. Compliance software tools. Software tools used to demonstrate energy
