SW, Everett WA 9B204 I ICI!ent: John Farris & Re ine Sullivan <br />Instructions: This single-family project will use the requirements of the Prescriptive Path below and <br />incorporate the minimum values listed. Based on the size of the structure, the appropriate number of <br />additional credits are checked as chosen by the permit applicant. <br />Provide all information from the following tables as building permit drawings: Table R402.1- Insulation and <br />Fenestration Requirements by Component, Table R406.2 - Fuel Normalization Credits and 406.3 - Energy Credits. <br />Authorized Re resentative -�" ��* <br />P Arra ana Hunkin `�5a�..�.��-.

When insulation is Installed in a cavity that is less <br />a than the label or design thickness of the insulation, the compressed R-value of the insulation from Appendix <br />Table A101.4 shall not be less than the R-value specified in the table. <br />b The fenestration U-factor column excludes skylights. <br />"10/15/21 +5TB" means R-10 continuous insulation on the exterior of the wall, or R-15 continuous insulation on <br />the interior of the wall, or R-21 cavity insulation plus a thermal break between the slab and the basement wall at <br />c the interior of the basement wall. "30/15/21 +5TB" shall be permitted to be met with R-13 cavity insulation on <br />the interior of the basement wall plus R-5 continuous insulation on the Interior or exterior of the wall. "5TB" <br />means R-S thermal break between floor slab and basement wall. <br />d R-30 continuous insulation is required under heated slab on grade floors. See Section R402.2.9.1. <br />For single rafter- or joist -vaulted ceilings, the insulation may be reduced to R-38 if the full insulation depth <br />e extends over the top plate of the exterior wall. <br />R-7.5 continuous Insulation installed over an existing slab is deemed to be equivalent to the required perimeter <br />f slab insulation when applied to existing slabs complying with Section R503.1.1. if foam plastic is used, it shall <br />meet the requirements for thermal barriers protecting foam plastics. - <br />For log structures developed In compliance with Standard ICC 400, log walls shall meet the requirements for <br />9 climate zone 5 of ICC 400. <br />Int. (intermediate framing) denotes framing and Insulation as described in Section A103.2.2 Including standard <br />h framing 16 inches on center, 78% of the wall cavity insulated and headers insulated with a minimum of R-10 <br />insulatlon. -. -- -- <br />Prescriptive Path - Single Family 2018 Washington State Energy Code-R <br />
