a. R-values are minimums. U-factors and SHGC are maximums. When insulation is installed in a cavity which is less than the label or design thickness of the insulation, the installed R-value of the insulation shall not be less than the R-value specified in the table.
b. The fenestration U-factor column excludes skylights. The SHGC column applies to all glazed fenestration.
Exception: Skylights may be excluded from glazed fenestration SHGC requirements in Climate Zones 1 through 3 where the SHGC for such skylights does not exceed 0.30.
c. “15/19” means R-15 continuous insulation on the interior or exterior of the home or R-19 cavity insulation at the interior of the basement wall. “15/19” shall be permitted to be met with R-13 cavity insulation on the interior of the basement wall plus R-5 continuous insulation on the interior or exterior of the home. “10/13” means R-10 continuous insulation 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 required slab edge R-values for heated slabs. Insulation depth shall be the depth of the footing or 2 feet, whichever is less in Zones 1 through 3 for heated slabs.
e. There are no SHGC requirements in the Marine Zone.
f. Basement wall insulation is not required in warm-humid locations as defined by Figure N1101.10 and Table N1101.10.
g. Or insulation sufficient to fill the framing cavity, R-19 minimum.
h. The first value is cavity insulation, the second value is continuous insulation, so “13+5” means R-13 cavity insulation plus R-5 continuous insulation.
i. The second R-value applies when more than half the insulation is on the interior of the mass wall.
j. Slab edge insulation may be eliminated for slab on grade floors when heating systems efficient rating is 90% or better.
5-807 Section R402.2.9 of the 2015 International Energy Conservation Code is hereby amended to read as follows:
R402.2.9 Basement walls. Walls associated with conditioned basements shall be insulated from the top of the basement wall down to 10 feet (3048 mm) below grade or to the basement floor, whichever is less. Walls associated with unconditioned basements shall meet this requirement unless the floor overhead is insulated in accordance with Section R402.1.2 and R402.2.8.
Exception: Basement walls that are otherwise exposed shall be insulated from the top of the basement wall down to 3 feet (914mm) below grade or the basement floor, whichever is less.

shall be permitted without additional joint seals. and seams of other
than the snap-lock and button-lock types.
R403.3.3 Duct Testing (Mandatory). Ducts shall be pressure tested to determine air leakage by one of the following methods:
1. Rough-in test: Total leakage shall be measured with a pressure differential of 0.1 inch w.g. (25 Pa) across the system, including the manufacturer’s air handler enclosure if installed at the time of the test. All registers shall be taped or otherwise sealed during the test.
2. Postconstruction test: Total leakage shall be measured with a pressure differential of 0.1 inch w.g. (25 Pa) across the entire system, including the manufacturer’s air handler enclosure. Registers shall be taped or otherwise sealed during the test.
Exceptions:
A duct air leakage test shall not be required where: the ducts
and air handlers are located entirely within the building thermal envelope.
1. The ducts and air handlers are located entirely within the building thermal envelope; or
2. A whole house air leakage test is performed.

the pump based on the identification of a demand for hot water within the
occupancy. The controls shall automatically turn off the pump when the water in
the circulation loop is at the desired temperature and when there is no demand
for hot water.
5-810 Section R403.5.3 of the 2015 International Energy Conservation Code is hereby amended to read as follows:
R403.5.3 Hot water pipe insulation (Prescriptive). Insulation for hot water pipe with a minimum thermal resistance (R-value) of R-3 shall be applied to the following:
1. Piping
3/4-inch (19 mm) and larger in nominal diameter.
2. Piping
serving more than one dwelling unit.
3.1. Piping located
outside the conditioned space.
4.2. Piping
from the water heater to a distribution manifold.
5.3. Piping
located under a floor slab.
6.4. Buried
in piping.
7.5. Supply and
return piping in recirculation systems other than demand recirculation systems.
