Project Information Contact Informatkm 1_949-N GNS Construction 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. lAuffmrized Representative All Climate Lanes able 8402.1.1 R -Value ° U -atm'' Fenestration U -Factor a n/a 0.30 Skylight U -Factor b n/a 0.50 Glazed Fenestration SHGC eje n/a n/a Ceiling' 49 0.025 Wood Frame Wall 9.1 21 int 0.056 Floor 30 0.029 Below Grade W all yh 10/15/21 Int + TB 0.042 Slab011-Value & Depth 10, 2 ft n/a R -values are minimums.

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 req uirements for thermal harriers protecting foam plastics. For log structures developed In compliance with Standard ECC 400, lag walls shall meet the requirements for 9 eiimate zone 5 of ICC 400. Int. (Intermediate framing) denotes framing and insulation as described in Section A103.2.2 including standard h framing 15 inches on center, 78% of the wall cavity insulated and headers insulated with a minimum of R-10 insulation.
