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.

R402.4.1.2 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
				 (3rd) 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.
