Envelope Requirements Summary, pg 2 ENV-REQ 2015 WSEC Compliance Forms for Commercial Buildings including R2,R3,&R4 over 3 stories and all R1 Revised Jun 2016 Definitions: Ls=Liner system--A continuous membrane installed below the purlins and uninterrupted by framing members.Uncompressed,unfaced insulation rests on top of the membrane between the purlins.Refer to Section A102.2.5.4. c.i.=Continuous insulation--Insulation that is continuous across all structural members without thermal bridges other than service openings and penetrations by metal fasteners with a x-sectional area of less than 0.04%of the opaque surface area of the assembly. Components with more than 0.04%metal penentrations may be eligible to follow the alternate CI values below. int=Intermediate framing--Includes insulated headers,corners and interior partition wall to exterior wall intersections.Refer to Section A103.2 for framing definitions. Footnote Summary: Each table in the 2015 WSEC has footnotes applicable to specific information provided in the table.This footnote summary provides only abbreviated details from these footnotes. Refer to 2015 WSEC for complete footnote information. Note 1-Assembly descriptions can be found in Chapter 2 and Appendix A. Note 2-Use of assembly U-factors,C-fanominal ctors and F-factors from Appendix A and Chapter 3 are required unless otherwise allowed by the provisions of this Code. Note 3-For metal building roofs where using R-value compliance method,a thermal spacer block is required.Otherwise use the U-factor compliance method. Note 4-Where heated slabs are below-grade,below-grade walls shall comply with the exterior insulation requirements for heated slabs. Note 5-Heated slab F-factors shall be determined specifically for heated slabs.Unheated slab F-factors shall not be used. Note 6-CMU walls in all occupancies other than Group R may be eligible for reduced insulation if all provisions stated in applicable footnote are met.Refer to Footnote D in Table C402.1.4 or Footnote C in Table C402.1.3 for eligibility requirements. Note 7-Components with continuous insulation but with metal penetrations/connections may be eligible for alternate continuous insulation R-values if all provisions in applicable footnote are met. Refer to alternate prescriptive R-values in table below and Footnote F in Table C402.1.3 for eligibility requirements. Alternate continuous insulation nominal R-values This alternate nominal R-value compliance option is allowed for projects complying with all of the following: 1.The ratio of the cross-sectional area,as measured in the plane of the surface,of metal penetrations of otherwise continuous insulation to the opaque surface area of the assembly is greater than 0.0004(0.04%),but less than 0.0012(0.12%). 2.The metal penetrations of otherwise continuous insulation are isolated or discontinuous(e.g.,brick ties or other discontinuous metal attachments,offset brackets supporting shelf angles that allow insulation to go between the shelf angle and the primary portions of the wall structure).No continuous metal elements(e.g.,metal studs,z-girts,z-channels, shelf angles)penetrate the otherwise continuous portion of the insulation. 3.Building permit drawings shall contain details showing the locations and dimensions of all the metal penetrations(e.g., brick ties or other discontinuous metal attachments,offset brackets,etc.)of otherwise continuous insulation.In addition, calculations shall be provided showing the ratio of the cross-sectional area of metal penetrations of otherwise continuous insulation to the overall opaque wall area. Assemblies with Alternate option for assemblies with Alternate option for assemblies with continnons metal penetrations,greater than metal penetrations,greater than or insulation(see 0.04%bat less than 0.08% equal to 0.08%bet less than 0.12% definition) R•9.Sd R-11 9ci 3-13ci R-11.4ci R-14.3ci R-15.7d R-13.3ci R-1d.6ci R-18.3d R-15 2ci R-19.Oct R-21d • R-30ci R-3S 3-42c1 R-38d R-4Sd R-53ci y..
