ApplicationsEmergency Smoke and SeismicEmergency Smoke ControlModels CUBE and USGFWhen you buy a Greenheck modelCUBE or USGF with the smokecontrol option, you receive a fanwith the industry’s best performanceand durability for smoke controlapplications (as found in emergencysmoke control systems).Note: Model sizes CUBE-099, 160XP,240XP, 300HP & 300XP are excludedfor Emergency Smoke Control.Refer to page 18 for size chart.SeismicModels CUE and CUBE UL/cUL Listed for 500 F (260 C) for 4 hoursand 1,000 F (538 C) for 15 minutes. Half the weight of traditional smoke controlfans, an ideal choice for roof load concerns. Low profile, height is less than half oftraditional smoke control fans, maximumof 481 8 inches (1,334 mm) from curb cap totop of the fan. Multiple applications, capable of exhaustinggeneral clean air and satisfying emergencysmoke control regulations.With changes in building codes and standards, more equipment is beingrequired to be seismically certified in areas of the country not commonlythought of as being in seismically active zones.The International Building Code (IBC) is designed to provide model coderegulations that safeguard public health and safety in all U.S. communities.With this code, the standards are intended to improve the performanceand design of nonstructural systems subject to seismic events.The state of California, one of the most active seismic areas in the UnitedStates, has the Office of Statewide Health Planning and Development(OSHPD). OSHPD regulates the design and constructionof health care facilities to ensure they are safe andcapable of providing services to the public aftera seismic event. OSHPD developed their ownunique certification process to incorporate the IBCand ASCE testing standards to ensure equipmentremains operable after a seismic event.Protocols designed for seismic standards:SeismicTesting CriteriaAll Greenheck seismically certified models have been tested using the most severe seismic event that is foundon the Spectral Response Map per IBC Figures 1613.5 (1-2). Our testing is performed under the worst-casescenario using the highest mapped seismic load, highest level occupancy category, worst-case site class, andhighest code mandated importance factor. This testing allows Greenheck seismically certified fans to be usedanywhere in the United States under any conditions.California OSHPDTest ProtocolsThe California Office of Statewide Health Planning and Development (OSHPD) requires all certified modelsto be shake table tested in accordance with ICC ES AC-156, in which the fans are physically subjected tothe same or greater forces than they will see during a seismic event. Subjecting models CUE and CUBEfans to this type of testing ensure the fans will operate without problems after a seismic event.OSHPD CertificationThe OSHPD certification numbers and supporting documents can be viewed on OSHPD’s website. Thisensures that the fan has been subjected to and passed rigorous testing standards.7
ApplicationsHigh Wind and HurricaneHigh Wind and HurricaneModels CUE, CUBE and USGFGreenheck is leading the High Wind Standard for rooftop fans and ventilators.Forceful winds are the cause of most hurricane damage. While forceful windsare not the only problem,wind-borne debris can alsocause detrimental effects toobjects and structures. Highwinds produce extreme forceson buildings and structures.By analyzing calculations,computer simulations, actualtesting, and other standards—Greenheck developed theHigh Wind Standard.Atlantic, Gulf and Pacific history of major hurricane tracks.Protocols designed to protect against wind-borne debris and severe wind loads:StructuralPerformance LoadA static load that is 1.5 times the design load (195 pounds per square foot pressure) is applied both positiveand negative to simulate wind force loads in each direction. Structural Performance per Dade CountyProtocol TAS-202 (ASTM E-330).Large MissileImpact TestLarge Missile Impact Testing is required when objects are 30 feet or less from the ground, The testis per Dade County Protocol TAS-201. The test unit is impacted three times with a piece of lumber(2 in. x 4 in. x 6 ft.) weighing approximately nine pounds and traveling at 34 mph. This simulateswind-borne debris striking the fan.Miami-Dade NOANumbersView the certifications on the Miami-Dade County website.
