• • 2018 Washington State Energy Code—Residential Prescriptive Energy Code Compliance for All Climate Zones in Washington Single Family—New&Additions(effective February 1,2021) These requirements apply to all IRC building types,including detached one-and two-family dwellings and multiple single-family dwellings(townhouses). Project Information Contact information Freeman Bathrm Addition C _ Instructions:This single-family project will use the requirements of the Prescriptive Path below and incorporate the minimum values listed. Based on the size of the structure,the appropriate number of additional credits are checked as chosen by the permit applicant. Provide all information from the following tables as building permit drawings:Table R402.1-Insulation and Fenestration Requirements by Component,Table R406.2-Fuel Normalization Credits and 406.3-Energy Credits.

"10/15/21+5TB"means R-10 continuous insulation on the exterior of the wall,or R-15 continuous insulation on the interior of the wall, or R-21 cavity insulation plus a thermal break between the slab and the basement wall at c the interior of the basement wall. "10/15/21+5TI3" shall be permitted to be met with R-13 cavity insulation on the interior of the basement wall plus R-5 continuous insulation on the interior or exterior of the wall. "5TB" means R-5 thermal break between floor slab and basement wall. d R-10 continuous insulation is required under heated slab on grade floors.See Section R402.2.9.1. For single rafter-or joist-vaulted ceilings,the insulation may be reduced to R-38 if the full insulation depth e extends over the top plate of the exterior wall. R-7.5 continuous insulation installed over an existing slab is deemed to be equivalent to the required perimeter f slab insulation when applied to existing slabs complying with Section R503,1.1. If foam plastic is used, it shall meet the requirements for thermal barriers protecting foam plastics. g For log structures developed in compliance with Standard ICC 400,log walls shall meet the requirements for climate zone 5 of ICC 400.
