2 SAMPlE cAlculAtIon In tHE VErtIcAl fAcAdE: SPEcIfIcAtIonof tHE StroKEthis sample calculation is based on the following classification:• WL 3000• SL 0• T(00)• B 300-E2.1. oBJEctIVEthe objective is to calculate the total aerodynamic smoke extraction cross section for this smoke section(A a target total) and to calculate the number of required windows.2.2. KnoWn dAtAthe following data are known from the specifications or the customer:• Profile system: xxx• Series: xx• Installation area: vertical facade• Casement width (W cM): 1200 mm• Casement height (H cM): 1600 mm• Clearance width ∆ w: 2 × 30 mm (series-dependent)• Clearance height ∆ h: 2 × 30 mm (series-dependent)• Type of opening and opening direction: Bottom hung vent, inward• Fill: glass, 6/12/6 mm (glass thicknesses: individual pane / space between panes / individual pane)• Installation position of the drives: on the side opposite to the hinges• Drive: chain drive, the same for all windows• Stroke: 1000 mm• Required aerodynamic free opening area: A a target total≥ 3.50 m²2.3. APProAcH2.3.1. dEtErMInInG tHE GEoMEtrIc oPEnInG ArEA A Vfor A WIndoWthe geometric opening area is calculated by multiplying the vent outer dimension width and the vent outerdimension height, in each case deducting the clearance width or height (∆ w and ∆ h):A v= clear width (rlB) × clear height (rlH)A v= (W cM– 2 ∆ w) × (H cM– 2 ∆ h)A v= (1200 – 60) × (1600 – 60)A v= 1140 × 1540A v= 1.76 m²36
2.3.2. dEtErMInInG tHE WIdtH/HEIGHt rAtIo of A cASEMEntthe width-height ratio is calculated from the ratio of clear width and clear height:W/H = clear width (rlB): clear height (rlH)W/H = (1200 - 60) : (1600 – 60)W/H = 1 140 : 1 540W/H = 0.74 → W/H < 1.002.3.3. dEtErMInInG tHE oPEnInG AnGlEthe opening angle is read off the following graph as a function of the stroke and the height. the values displayedon this graph are based on a simple sine trigonometric function. the graph is universally applicable across allsystems:Ratio of the opening angle to the height dependent on the strokeSash height Fh [mm]Stroke 800Opening angle [DEG]Stroke 300Stroke 1100Stroke 400Stroke 1200Stroke 500Stroke 1300Stroke 600 Stroke 700 Stroke 800 Stroke 900Stroke 1400Stroke 1000In this sample calculation, an opening angle of 37° is calculated at a vent height of 1,600 mm and a stroke ofTeil A1,000 mm.2.3.4. dEtErMInInG tHE coEffIcIEnt of dIScHArGE cV0using the width-height ratio determined under 2.3.2., the coefficient of discharge cv0 required for the nextcalculation can now be read off the corresponding table for the system:Openingasinwardsbottom/tophungFrame cleardimensions overlapWWWWOpening angle°At a width-height ratio of 0.74 and an opening angle of 35°, the coefficient of discharge cv0 is 0.40.
