Emergency Smoke Control

When you buy a Greenheck
model GB with the smoke
control option, you receive a
fan with the industry's best
performance and durability for
smoke control applications
(as found in emergency smoke
control systems).

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 non-structural 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 healthcare facilities
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.
When using the fans in applications which are not covered by California OSHPD standards, Greenheck
models G and GB have been certified by a third party engineering firm to IBC 2009, 2012 and ASCE
7-05 standards. These engineers hold professional engineering (P.E.) licenses in all 50 states, so no
matter where your job is located, you are backed by a P.E. signature for your state.
All Greenheck seismically certified fan models have gone through extensive testing procedures.
Greenheck models G and GB have been certified to IBC 2009, 2012, ASCE 7-05 and California OSHPD
standards through both engineering calculations and shake table testing of all models by independent
third party engineering firms.
