Distinctive Features + Diverse Applications + Multitude of Benefits: Can be specified in modular panels or as a continuous application For a seamless, uninterrupted façade Ideal for inverted louvre situations (eg plant screens) Attention to Detail: 55% free open area Maximum blade span: 1500mm Maximum blade length: 6500mm Designed, engineered and certified for incidental live load. SEAMLESS, UNINTERRUPTED FACADE

2 Jupiter LOUVRE DATA SHEET Louvreclad s Jupiter Louvre was tested in CFD in 2D as requested by Louvreclad. 2D Simulation CFD by Autodesk was used to perform a steady state Computational Fluid Dynamic Analysis in order to obtain credible data on this louvre. Five equally spaced test velocities, with the fifth test velocity being at least 3 times greater than the first, were used to obtain pressure drops at each instance. These pressure drops were then used to calculate the Ci value for each instance and averaged out to a Cd value for the product. These were all done according to AS4740. Figure 1: Jupiter Louvre Chevron CFD Testing, Velocity Vector PERFORMANCE SPECIFICATIONS: Free Open Area, FOA = 55% A percentage of error of 5% in the determination of the pressure drop was also included in the calculations in order to provide a more reliable result. SST k-omega SAS turbulence model was used. The following equation was used as per AS4740 to calculate the coefficient of discharge using the pressure drop across the louvre. Coefficient of Discharge, Cd = Effective Aerodynamic Area, EAA = 0.29 PERFORMANCE LEVEL: According to AS 4740: 2000 (Natural Ventilators Classification and performance) Airflow Performance: Class 2 Where, = discharge coefficient for each air velocity = flow rate of air, m 3 /s A = throat area of ventilator, m² = air density, kg/m³ = pressure drop across louvre, Pa Note: Testing relates to the Jupiter Series standard louvre only.

3 Jupiter LOUVRE Water Ingress Performance Louvreclad s Jupiter Louvre was tested in CFD to identify its class for water ingress under AS-4740 as requested by Louvreclad. 3D Simulation CFD by Autodesk was used to perform a steady state Computational Fluid Dynamic Analysis in order to obtain water penetration data on this louvre. Figure 1: Jupiter Louvre water ingress CFD Testing WATER INGRESS PERFORMANCE: Minimum Effectiveness, E = WATER INGRESS PERFORMANCE LEVEL: According to AS 4740: 2000 (Natural Ventilators Classification and performance) Rain Penetration Performance: Class B Note: Naturally CFD cannot guarantee that there will be no more water ingress in all conditions because of the variables involved. Therefore, a percentage of error of 5% in the determination of the water penetration and the effectiveness was also included in the calculations in order to provide a more reliable result. The 1000 x 1000 mm 2 louvre was mounted in a section of wall 3000 x 3000 mm² and subjected to an air stream into which water has been introduced to simulate winddriven rain. The louvre was monitored for water penetration. 8 equally spaced test louvre core air velocities, ranging from 0 to 3.5 m/s in increments of 0.5 m/s have been considered at a constant simulated heavy rainfall rated at 75 L/h.m 2. All tests were conducted at a simulated wind speed of 13 m/s on the centreline of the louvre and 1 m in front of its face. These were all done according to AS4740 Appendix B. SST k- SAS turbulence model was used. About 1000 uniform rain droplets with a size of 2 mm and a coefficient of restitution of 0.25 have been used for the rain simulation to obtain the effectiveness of the louver: E=100.((75.A-q d).(75.a) -1 ) q d= water penetration rate, L/h A = Louvre face area, m² Note: Testing relates to the Jupiter Series standard louvre only.
