M <br />Note 1- Insulation that is continuous except iteners may be entered here if the cross -sectional a eta/ penetration through otherwise <br />continuous insulation is less than 0. <br />Note 2 - Altemate prescriptive continuous insulation R-values per Table C402.1.4, Footnote F may be used if the cross sectional area of metal <br />penetrations exceeds 0.04% but is less than 0.12%. Calculations are required to use these alternate R-values. <br />Note 3 - Opaque assembly U-factors shall come from Appendix A or calculated per approved method as specified in C402.1.5.1. Specify the <br />table number or calculation page number. <br />Note 4 - Thermal spacer blocking and liner system are required for prescriptive R- Value compliance in metal building roof assemblies. Note thermal <br />spacer thickness and R-value in roof assembly description. <br />Note 5 - Intermediate framing is required for prescriptive R-Value compliance in wood -framed wall assemblies. <br />Note 6 - Proposed CMU mass walls in non -Group R that meet Table C402.1.4 Footnote C requirements can enter the target prescriptive <br />U-value of 0.104. <br />Note 7 - Mass transfer slab edges must be covered with an assembly having an overall U-factor of 0.2. <br />Note 8 - Refer to Table C402.1.3, Footnote E for prescriptive R- Value requirement for steel floor joist assemblies. <br />Note 9 - Prescriptive slab -on -grade insulation shall extend from top of slab to minimum length per an approved method as defined in C402.2.6. <br />Note 10 Slab -on -grade F-Factors shall come from Appendix A or calculated per approved method as specified in C402.1.5.1. <br />Note 11 Opaque door U-factors shall come from Appendix A or calculated per approved method as specified in C402.1.5.1. A door is defined as <br />opaque if less than 50% of the door area has glazing. <br />Note 12 - Refer to Equation C4-6 Projection Factor Calculation. <br />Note 13 - N = Oriented within 45 degrees of true north, SEW = All other orientations. <br />Note 14 - Fenestration assembly U-Factor and SHGC shall be the manufacturer's NFRC product rating, which includes the glazing and frame, or <br />shall be the default value per Section C303.1.3. <br />Note 15 - List all above -grade Group R mass walls and steel frame walls in Group R Walls section. List commercial above grade walls and all other <br />Group R above grade walls in Opaque Walls - Above Grade. <br />Note 16 - Refrigerated Coolers - All cooler roof, wall and door assemblies shall comply with the prescriptive R-values or U-factors per C410. Enter <br />proposed information under the most similar assembly type. Slab edge insulation for slab -on -grade floors shall comply with C402. Floors that <br />separate a cooler from a non -cooler space (unconditioned and conditioned) shall be insulated per C402. Vertical fenestration (not within <br />cooler doors) shall comply with the prescriptive R-values or U-factors per C402. Enter only the opaque portion of refrigerated space doors. <br />Windows within doors and reach -in display case doors shall comply with C410 prescriptive requirements. <br />Note 17 - Refrigerated Freezers - All freezer roof, wall and door assemblies shall comply with the prescriptive R-values or U-factors per C410. Enter <br />proposed information under the most similar assembly type. Freezer floor insulation shall comply with C410. Insulation is required under the <br />entire freezer floor. If the freezer floor assembly rests on top of a standard floor, the vertical edge of the freezer floor shall be entered as and <br />comply with the requirements for a freezer wall. If freezer floor insulation is installed as integral to or applied underneath a slab -on -grade or <br />exposed floor, this floor shall be thermally broken from the surrounding floor area with the same amount of insulation as required for a freezer <br />floor. Enter proposed thermal break information in the Freezer Floor section and note it as In -Floor Thermal Break. Enter only the opaque <br />L�) <br />
