[ X] New Construction. All conditioned spaces within residential buildings must comply with Table N1101.1 (1) and two additional measures (one numbered and one lettered) from Table N1101.1 (2)

[ ] Additions. Additions to existing buildings or structures may be made without making the entire building or structure comply if the new additions comply with the requirements of this chapter. (N1101.3)

[ ] Large additions. Additions that are equal to or more than 40 percent of the existing building heated floor area or 600 square feet (55 m2) in area, whichever is less, must comply with Table N1101.1(2)

] Small additions. Additions that are less than 40 percent of the existing building healed floor area or less than 600 square feel in area, whichever is less, must select one measure from Table N1101.1 (2) on page 2 or comply with Table N1101.3 below. (N1101.3)

] Exception: Additions that are less than 15 percent of existing building heated floor are or 200 square feet (18.58 m2) in area, whichever is less, are not required to comply with Table N1101.1 (2) or Table N1101.3.

Selected item number: 2 Selected item letter: C ( TABLE N1101.3-SMALL ADDITION ADDITIONAL MEASURES ) --------- ---------

1 Increase the ceiling insulation of the existing portion of the home as specified in Table N1101.2 2 Replace all existing single-pane wood or aluminum windows to be U-value as specified in Table N1101.2 3 Insulate the floor system as specified in Table N1101.2 and install 100 percent of permanently installed lighting fixtures

as CFL, LED or linear fluorescent or min. efficacy of 40 lumens per watt as specified in Section N 1107.2 4 Test the entire dwelling with blower door and exhibit no more than 6.0 air changes per hour@ 50 Pascals. 5 Seal and performance test the duct system. 6 Replace existing 78 percent AFUE or less gas furnace with a 92 percent AFUE or greater system. 7 Replace existing electric radiant space heaters with a ductless mini-split system with a minimum HSPF of 10.0. 8 Replace existing electric forced air furnace with an air source heat pump with a minimum HSPF of 9.5. 9 Replace existing water heater for a water heater meeting Conservation Measure D (Table N1101.1 (2))

a. As allowed in Section N1104.1, thermal performance of a component may be adjusted provided that overall heat loss does not exceed the total resul�ng from conformance to the required U-value standards. Calculations to document equivalent heat loss shall be perform9d using the procedure and epprovad U-values contained in Tab le N1104.1(1)

b. R-velues used In this tab le are nominal for the Insulation only In standard wood framed construction and not for the entire assembly. c. wa11Insulallon requirements appl)' to all axtertor wood framed, concrete or maaonrywalls that are above grade. This Includes a1pple walls and rtm Joist areas. R-19 AdVancad Frame or 2x4 wall with rigid insulation may be aubalitutad if total nominal insulation R-value is 18.5 or greater. d. The wall component shall be a minimum solid log ortimber wall thickness of 3.5 inches (90 mm). e. Below-grade wood, concrete or masonry walls include all walls that are below grade and do not include those portions of such wall that extend more than 24 inphes (609.6 mm) above grade. f, Insulation levels for ceilings that have limited attit:/rafter depth such as dormers, bay windows or similar arc:hiteciural features totaling not more than 150 square feet (13.9 m} in area may be reduced to not less than R-21.

When reduced, the cavity shall be filled (except for required Yentilatiori spaces), g. The maximum vaulted celling surface area shall not be greater than 50 percent of the total heated space floor area unless area has a U-factor no greater than U-0.026. (equlvllent to R-38 fatter or scissor truss with R-38 advanced framing) h. A=Advanc:ed frame construction, which shall provide full required Insulating value to Iha outside of exterior walls. i. Heated slab interior applies to concrete slab floors (both on Elnd bEllow grade) th Ell incorporate a rediant heating system within the slab. Insulation shall be install&d undemeatt, Iha entire slab. j. Sliding glallll doors shall oompi)' with window performance requirements. Windows exempt from testing in aooordance with Section NF1111.2, Item 3 shall comply with window performance requirements if oonatrucied with lharmal break

aluminum or wood. or vinyl, or fiberglass frames and double-pane glazing with low-emissivity coatngs of 0.10 or less. Buildings designed to incorporate passive solar elements may include glazing with a U-factor greater than 0.35 by using Table N1004.1(1) to demonstrate equivalence Ill building envelope requirements.

k. Reduced window area may not be used as a trade-offcrilarion forlharmal performance of any component. I. Skylight araa installed at 2 percent or less of total heated space floor area shall be deemed to satisfy this requirement with vinyl, wood or thermally broken aluminum frames and doub le-pane glazing with low-emiEEivity coatings.

Skylight LI-factor is tested in 1he 20 degree (0.35 rad) overhead plane per NFRC stenderds. m. A mexlmum of 2B square feet {2.&n ) of extertor door erea per dwelling unit can have a U-tactor of 0.54 or lass. n. Glazing that Is either double pane with low-a cos�ng on one surface, or trlpla pane shall be dee mad to comply with this U-0.40 requirement.
