• Multiple applications, capable of exhausting general clean air and satisfying emergency smoke control regulations.

With changes in building codes and standards, more equipment is being required to be seismically certiﬁed in areas of the country not commonly thought of as being in seismically active zones.

The International Building Code (IBC) is designed to provide model code regulations that safeguard public health and safety in all U.S. communities. This code is intended to improve the performance and design of nonstructural systems subject to seismic events.

The State of California, one of the most active seismic areas in the United

States, has the Ofﬁce of Statewide Health Planning and Development

(OSHPD) to regulate the design and construction of health care facilities

to ensure they are safe and capable of providing

services to the public after a seismic event.

OSHPD developed their own unique certiﬁcation

process to incorporate the IBC and ASCE testing standards to ensure equipment remains operable after a seismic event.

Note: All G and GB models meet seismic

requirements.

Protocols designed for seismic standards:

All Greenheck seismically certified models have been tested using the most severe seismic event that is

found on the Spectral Response Map per IBC Figures 1613.5 (1-2). Our testing is performed under the worst case scenario using the highest mapped seismic load, highest level occupancy category, worst case site class, and highest code mandated importance factor, thereby allowing Greenheck’s seismically certified fans to be used anywhere in the United States under any conditions.

The California Office of Statewide Health Planning and Development (OSHPD) requires all certified models be shake table tested in accordance with ICC ES AC-156, in which the fans are physically subjected to the same or greater forces than they will see during a seismic event. Subjecting Greenheck model G and GB fans to this type of testing ensures the fans will operate without problems after a seismic event.

The OSHPD certification numbers and supporting documents can be viewed on OSHPD’s website ensuring that the fan has been subjected to and passed rigorous testing standards.

High Wind and Hurricane - G and GB

Greenheck is leading the High Wind Standard for roof top fans and ventilators. Forceful winds and wind-borne debris are the cause of most hurricane damage. Hurricane winds start at 75mph and can exert a force of 75poundspersquarefoot of pressure—or over 900pounds on a fan and curb. Forceful winds are not the only problem; wind-borne debris can also cause detrimental effects to objects and structures. High winds and extreme forces are the cause of most storm damage. By analyzing calculations, computer simulations, actual testing, and other standards—Greenheck developed the High Wind Standard.

Demand Control Ventilation for Multistory Buildings

Applications requiring constant pressure or variable volume can utilize G fans with Vari-Green motors and Vari-Green controls. Demand control ventilation systems reduce the amount of energy used by decreasing the speed of the fan when demand is low. This lessens the amount of conditioned air exhausted, and in turn, reduces the total operating costs associated with air conditioning and heating in multistoried buildings including hotels, multifamily complexes, institutional facilities, and high-rise commercial buildings.

Fan Inlet Connections

To ensure proper fan performance, exercise caution in fan placement and connection to the ventilation system. Obstructions, transitions, poorly designed elbows, improperly selected dampers, etc., can cause reduced performance, excessive noise, and increased mechanical stress. For performance to be as published, the system must provide uniform and stable airﬂow into the fan.

Provide uniform airﬂow at fan inlet to ensure

optimum performance.

Provide uniform airﬂow at fan inlet and through

the damper to ensure optimum performance.

Dampers must open fully. Use motorized

dampers in low airﬂow applications to reduce losses.

Avoid sharp turns or entrance conditions that

cause uneven ﬂow. Use turning vanes in elbows to reduce adverse effects.
