nis chapter has been revised in its entirety, there will be no marginal markings. <br />SECTION 401 <br />GENERAL <br />401.1 Scope. This chapter applies to residential buildings. <br />401.2 Compliance. Projects shall comply with Sections 401, <br />402.4, 402.5, 402.6 and 403 (referred to as the mandatory pro- <br />visions) and either: <br />1.. Sections 402A through 402.3 (prescriptive); or <br />2. Section 404 (performance). <br />4013 Certificate. A permanent certificate shall be posted on <br />or.in the electrical distribution panel. The certificate shall be <br />completedby the builder or registered design professional. The <br />certificate shall list the predominant R-values- of insulation <br />installed in or on coiling/roof, walls, foundation (slab, base- <br />mentwall, crawlspace wall and/or floor) and ducts outside con- <br />ditioned spaces; U-factors for fenestration; and the solar heat <br />gain coefficient (SHGC) of fenestration. Where there is more <br />than one value for each component, the certificate shall list the <br />value covering the largest area The certificate shall Jilt the typo <br />and efficiency of heating, cooling and service water heating <br />equipment. <br />, "i- C? <br />7 <br />SECTION 402 <br />BUILDING THERMAL ENVELOPE <br />402.1 General. (Prescriptive). <br />402.1.1 Insulation and fenestration criteria. The building <br />thermal envelope shall meet the requirements of Table <br />402.1.1 based on the climate zone specified in Chapter 3. <br />402.1.2 1?-value computation. lasulation material used in <br />layers, such as framing. cavity insulation and insulating <br />sheathing, shall be sumed to compute the component <br />R-value. The manufacturer's settled R-value shall be used <br />for blown insulation. Computed R-valuos shall not include <br />an R-value for other building materials or air films. <br />-402.1.3 U factor alternative. An assembly with a U-factor <br />equal to or less than that specified in Table 402.1.3 shall be <br />permitted as an alternative to then -value in Table 402.1.1. <br />Exception., For mass walls not meeting the criterion for <br />insulation locationin Section 402.2.3, the U-factor shall <br />be permitted to be: <br />1. U-factor of 0.17 in Climate Zone 1. <br />2. U factor of 0.14 in Climate Zone 2. <br />3. U-factor of 0.12 in Climate Zone 3. <br />TABLE 402.1.1 <br />INSULATION AND FENESTRATION REQUIREMENTS 13Y COMPONENT' <br />CRAWL <br />GLAZED <br />WOOD <br />MASS <br />.BASEMENT' <br />SLAB° <br />SPACE` <br />CLIMATMZ <br />FENESTRATION <br />SKYLIGHT6 <br />FENESTRATION <br />FILING <br />FRAME WALL <br />WALL <br />FLOOR <br />WALL <br />R-VALUE <br />WALL. <br />ONE <br />fJ-FACTDR <br />U-PACTOR <br />SHGC <br />R-VALUE <br />R-VALUE _ <br />R-VALU> <br />_R VALUE. <br />8-VALUE _ <br />..8, DEPTH._ <br />R-VALUE <br />1 <br />1.20 <br />0.75 <br />0.40 <br />30 <br />13 <br />3 <br />13 <br />0 <br />0 <br />0 <br />-.2 . <br />0.75 <br />0.75 <br />0.40 <br />30 <br />13 <br />4 <br />13• <br />0 <br />0 <br />0 <br />3 <br />0.65 <br />0.65 <br />0.400 <br />30 <br />13 <br />5 <br />19 <br />i 0 <br />0 <br />5/13 <br />4 except <br />Marine <br />0.40 <br />0.60 <br />NR <br />38 <br />13 <br />5 <br />19 <br />10/13 <br />10, 2 ft <br />10/13 <br />5 and <br />Marine 4 <br />0.35 <br />0.60 <br />NR <br />38 <br />19 or 13+51 <br />13 <br />30f <br />10 / 13 <br />10, 2 ft <br />10/13 <br />6 <br />0.35 <br />0.60 <br />NR <br />49 <br />19 or 13+59 <br />15 <br />30' <br />10/13 <br />10, 4 ft <br />.10/13 <br />7 and 8 <br />0.35 <br />0.60 <br />NR <br />49 <br />21 <br />19 <br />301f <br />10/13 <br />10, 4 ft <br />10113 <br />For SI: 1 foot = 304.8 mm <br />a.
