Project information 2589-ZA CE DEVELOPMENT 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. 1AuthorhWdRepre$entadve1F___ - IlDote All Climate Zones Vable R402.1.1 R-ValueU-Factor' Fenestration U -Factor b n/a 0.30 Skylight U -Factor b n/a 0.50 Glazed Fenestration SHGC b.e n/a n/a Ceiling B 49 0.026 wood Frame Wall &" 21 int 0.056 Floor 30 0.029 Below Grade Wall a 10/15/21 Int +T8 0.042 Slab " R -Value & Depth 10, 2 ft n/a R -values are minimums.

"10/15/21 +5TB" 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 de 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 re u1rements for thermal harriers protectin foam p lastics. For log structures developed In compliance with Standard ICC 400, log walls shall meet the requirements for g climate zone 5 of ICC 400. int. (Intermediate framing) denotes fram€ng and insulation as described in Section A203.1.2 including standard h framing 16 inches on center, 78% of the wall cavity insulated and headers Insulated with a minimum of R-10 insulation. Prescriptive Path - Single Family 2018 Washington State Energy Code -R 2018 Washington State Energy Code - Residential Prescriptive Energy Code Compliance for All Climate Zones in Washington_ Single Family=`v & Additions (effective Febidary 1, 202 1) Each dwelling unit in a residential building shall comply with sufficient options from Table R406.2 (fuel normalization credits) and Table 406.3 (energy credits) to achieve the following minimum number of credits. To claim this credit, the building permit drawings shall specify the option selected and the maximum tested building air leakage, and show the qualifying ventilation system and its control sequence of operation. 1. Small Dwelling Unit: 3 credits Dwelling units less than 1,500 sf in conditioned floor area with less than 300 sf of fenestration area. Additions to existing building that are greater than 500 sf of heated floor area but less than 1,500 sf. 2. Medium Dwelling Unit: 6 credits All dwelling units that are not included in #1 or #3 3. Large Dwelling Unit: 7 credits Dwelling units exceeding 5,000 sf of conditioned floor area 4.
