With changes in
building codes
and standards,
more equipment
is 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.
The IBC 2009 is the latest version adopted on state
or local levels. With this code, the standards are
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). OSHPD regulates the design and
construction of healthcare 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.

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). Because 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, this allows Greenheck 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 models SWB, SFD and SFB fans
to this type of testing ensures the fans will
operate without problems after a seismic
event. (OSP-0113-10 - SWB Series 100 and

High

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. At speeds over 150 mph, wind
can exert a force of 75 pounds per square foot of
pressure or over 900 pounds on a fan. 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 and actual testing—Greenheck
developed the High Wind Standard.
