Heated' I R-15 for 36" below + R-5 full slab <br />For SI:1 inch = 25.4 mm,1 pound per square foot = 4.88 kg/m=, 1 pound per cubic foot =16 kg/m=. <br />ci = Continuous Insulation, NR = No Requirement, LS = Liner System. <br />a.Where using li-value compliance method, a thermal spacer block shall be provided, <br />b.Where heated slabs are below grade, below -grade walls shall complywith the exterior insulation requirements for heated <br />slabs. <br />c."Mass floors" shall be in accordance with Section C402.2.3. <br />d."Mass walls" shall be in accordance with Section C402.2.2. <br />e.The first value is for perimeter insulation and the second value is for full, under -slab insulation. <br />8. Section C402.1.4 Assembly U factor, C factor or F factor -based method, <br />is hereby deleted in its entirety. <br />9. Section C402.1.5 Component performance alternative, is hereby deleted <br />in its entirety. <br />10. Table C402.4 Building Envelope Fenestration Maximum U-Factor and <br />SHGC Requirements, is hereby deleted and replaced with the following: <br />Table C402.4 <br />Building Envelope Fenestration <br />Vertical Fenestration <br />Maximum U-Factor <br />0.30 <br />Maximum SHGC <br />0.33 <br />Maximum Air leakage rate for all fenestration except curtain walls <br />and storefront glazing <br />.20 cfm/ft2 <br />Maximum air leakage rate for curtain walls and storefront glazing <br />.06 cfm/ft <br />Skylights <br />Maximum U-Factor <br />0.50 <br />Maximum SHGC <br />0.40 <br />Maximum Air leakage rate <br />.20 cfin/ft2 <br />11. Section C402.4.1 Maximum area, is hereby deleted and replaced with the <br />following: <br />1402.4.1 Minimum area of natural lighting. Not less than eight percent <br />of the floor area shall be glazed. <br />12. Section C402.4.2 Minimum skylight fenestration area, is hereby deleted <br />and replaced with the following: <br />Commented [CD3]: This seems confusing. How <br />does minimum floor area convert to minimum <br />percent of exterior walls with glazing? <br />
