For SI: 1 foot = 304.8 mm.

a. R-values are minimums U-factors and SHGC are maximums. R-19 batts compressed into a nominal two by six (2 × 6) framing cavity such that the R- value is reduced by R-1 or more shall be marked with the compressed batt R-value in addition to the full thickness R-value.

b. The fenestration U-factor column excludes skylights. The SHGC column applies to all glazed fenestration.

c. "10/13" means R-10 continuous insulated sheathing on the interior or exterior of the home or R-13 cavity insulation at the interior of the basement wall.

d. R-5 shall be added to the entire slab and the required slab edge R-values for heated slabs

e. Or insulation sufficient to fill the framing cavity, R-19 minimum.

f. "13+5" means R-13 cavity insulation plus R-5 insulated sheathing. If structural sheathing covers twenty-five percent (25%) or less of the exterior, insulating sheathing is not required where structural sheathing is used. If structural sheathing covers more than twenty-five percent (25%) of exterior, structural sheathing shall be supplemented with insulated sheathing of at least R-2.

g. The second R-value applies when more than half the insulation is on the interior of the mass wall.

R402.1.5 Total UA alternative delete and substitute:

R402.1.5 Total UA alternative. If the total building thermal envelope UA (sum of U-factor times assembly area) is less than or equal to the total UA resulting from using the U-factors in Table R402.1.3 (multiplied by the same assembly area as in the proposed building), the building shall be considered in compliance with Table R402.1.1. The UA calculation shall include the thermal bridge effects of framing materials. The UA calculation shall include the thermal bridging effects of framing materials. The SHGC requirements shall be met in addition to UA compliance

R402.4.1.2 Delete and substitute the following:

R402.4.1.2 Testing. The building or dwelling unit shall be tested, and the air leakage rate shall be verified. Testing shall be conducted with a blower door at a pressure of two tenths of one inch (0.2") (fifty (50) Pascals). Maximum air change rates per hour: 5. Testing shall be conducted by an approved third (3^rd) party, where required by the building official. A written report of the results of the test shall be signed by the party conducting the test and provided to the building official. Testing shall be performed at any time after creation of all penetrations of the building thermal envelope.

During testing:

1. Exterior windows and doors, fireplace and stove doors shall be closed, but not sealed, beyond the intended weather-stripping or other infiltration control measures;

2. Dampers including exhaust, intake, makeup air, backdraft and flue dampers shall be closed, but not sealed beyond intended infiltration control measures;

3. Interior doors, if installed at the time of the test, shall be open.

4. Exterior doors for continuous ventilation systems and heat recovery ventilators shall be closed and sealed.

5. Heating and cooling systems, if installed at the time of the test, shall be turned off; and

6. Supply and return registers, if installed at the time of the test, shall be fully open.
