Vertical Fenestration Target Area Adjustment Calculations <br /> If vertical fenestration area exceeds maximum allowed per Section C402.4.1,then Target Area Adjustment of all applicable envelope elements is <br /> required. This worksheet automatically calculates these adjustments and updates target areas in the ENV-UA and ENV-SHGC worksheets. Information <br /> shown in this worksheet is for reference only and is write-protected.Submit this Target Area Adjustment form with ENV-UA and ENV-SHGC forms. <br /> VF=Vertical fenestration NW=Net above grade wall(excludes fenestration and doors.) <br /> DR=Opaque doors Gross Exterior Above-Grade Wall Area=VF+NW+DR <br /> AG=Above-grade <br /> Proposed Areas <br /> Vertical Fenestration-> VF= 571.0 <br /> Opaque-> NW= 1236.0 DR= <br /> Gross Exterior Max Vert.Fen.% Maximum Target <br /> AG Wall Area (C402.3.1) Vert.Fen.Area <br /> 1807.0 X 30.0% ± 100 = 542.1 <br /> Total Vertical Delta Vertical Excess Vertical <br /> Fenestration Maximum Target Fenestration 0 Fenestration <br /> 571.0 - 542.1 = 28.9 II greater = 28.9 <br /> ------ 28.9 <br /> / Multiplier applied to all <br /> Total Vertical Excess Vertical / Target Vertical Total Vertical Proposed Vertical <br /> Fenestration Fenestration Fenestration Fenestration Target VF Multiplier calculateFenestration Target Areasr to <br /> 571.0 - 28.9 = 542.1 - 571.0 = 0.95 eeTarget Vertical <br /> • Fenestration Area <br /> Net AG Wall Area Excess Fenestration Target Net Wall Area Net Wall Target Net Wall Mult.
