For SI: 1 foot = 304.8 mm.

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: In Climate Zones 1 through 3, skylights will be permitted to be excluded from glazed fenestration SHGC requirements, provided that the SHGC for such skylights does not exceed 0.30.

c.             “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. “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. Alternatively, “15/19” shall be R-13 cavity insulation on the interior of the basement wall plus R-5 continuous insulation on the interior or exterior of the home.

d.             R-5 shall be provided under the full slab area of a heated slab in addition to the required slab edge insulation R-value for slabs, as indicated in the table. The slab edge insulation for heated slabs shall not be required to extend below the slab.

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 R301.1 and Table R301.1.

g.             Alternatively, insulation sufficient to fill the framing cavity and providing not less than an R-value of R-19.

h.             The first value is cavity insulation, the second value is continuous insulation. Therefore, as an example, “13+5” means    R-13 cavity insulation plus R-5 continuous insulation.

i.              Mass walls shall be in accordance with Section R402.2.5. The second R-value applies where more than half of the insulation is on the interior mass of the wall.

5-807               Section R402.2.9 of the 2018 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 comply with this requirement except where 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.

5-808               Section R402.4.1.2 of the 2018 International Energy Conservation Code is hereby amended to read as follows:

R402.4.1.2 Testing. The building or dwelling unit shall be tested and verified as having an air leakage rate not exceeding five air changes per hour in Climate Zones 1 and 2, and three air changes per hour in Climate Zones 3 through 8. Testing shall be conducted in accordance with RESNET/ICC 380, ASTM E779 or ASTM E1827 and reported at a pressure of 0.2 inch w.g. (50 Pascals). Where required by the code official, testing shall be conducted by an approved third party. A written report of the results of the test shall be signed by the party conducting the test and provided to the code 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 weatherstripping 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, where installed at the time of the test, shall be open.

4.         Exterior or interior terminations for continuous ventilation systems shall be sealed.

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

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

Exception: When all reasonable efforts by an approved third party cannot verify an air leakage rate not exceeding three air changes per hour in Climate Zone 4, a written report of the efforts and results shall be made and signed by the party conducting the test and shall be provided to the code official. The code official is authorized to approve administratively a building or structure having a maximum of three and one-half air changes per hour.

5-809               Section 403.3.3 of the 2018 International Energy Conservation Code is hereby amended to read as follows:

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:

1.         A duct air-leakage test shall not be required where the ducts and air handlers are located entirely within the building thermal envelope.

2.         A duct air-leakage test shall not be required for ducts serving heat or energy recovery ventilators that are not integrated with ducts serving heating or cooling systems.

3. A duct air-leakage test shall not be required where a whole house air-leakage test is performed.

A written report of the results of the test shall be signed by the party conducting the test and provided to the code official.

5-810               R403.5.1.1 of the 2018 International Energy Conservation Code is hereby amended to read as follows:

                        R403.5.1.1 Circulation systems. Heated water circulation systems shall may be provided with a circulation pump. The system return pipe shall be a dedicated return pipe or a cold water supply pipe. Gravity and thermo-syphon circulation systems shall be prohibited. Controls for circulating hot water system pumps shall start 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.

5-811               Section R403.5.3 of the 2018 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 not less than 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.
