Fact Sheet – Compliance with International Building Codes
OVERVIEW: Johnson Controls has a long history of leadership in the seismic engineering field. We have been
offering certificates of compliance in accordance with the International Building Code (IBC) since
2004. We have maintained an active presence in this arena and as compliance requirements
increase from the Office of Statewide Health Planning and Development (OSHPD), we will
aggressively manage meeting or exceeding those requirements. OSHPD is regulating agency for
the installation of HVAC and Fire Life Safety systems and non-structural equipment in California
health care facilities.
DESCRIPTION: Driven by market forces, the emergence of IBC Seismic Codes and the adoption of IBC by all
states, Johnson Controls elected to accept a leadership position in the area of seismic certification
to sustain our competitive advantage in the marketplace as follows:
HISTORY: • Johnson Controls has regularly interacted with OSHPD since 2003 on complex support issues for
seismic certification on health care facilities in California.
• In 2004 a cross-functional team was formed to elevate and address safety and ensure seismic
compliance.
• We have supported ASHRAE research at the Multi-Disciplinary Center for Earthquake Engineering
Research (MCEER) to quantify the amplification effects of spring isolated HVAC equipment.
• We pioneered shake-table testing and analysis of a complete commercial chiller that was
charged, filled with water and subsequently operated; both rigid and spring isolated.
• We have performed analytical dynamic response comparisons for our flagship large tonnage
centrifugal chiller line.
• In March 2005, we achieved IBC seismic certification for our flagship large tonnage centrifugal
chiller line by shake table testing and analysis per American Society of Civil Engineers 7.
• In June 2009, we received 3rd party IBC seismic certification for many sizes of indoor and
outdoor air handler unit fans by shake table testing and analysis per ASCE 7.
• In November 2009, we received OSHPD Special Seismic Certification for our flagship large
tonnage chiller.
INVOLVEMENT: • We were instrumental in the creation of the AHRI seismic subcommittee, which is drafting the
first seismic analysis standard that will address HVAC equipment.
• We maintain an active presence on the following committees that are helping to develop the
next generation of seismic regulations: Building Seismic Safety Council (BSSC), ASHRAE TC 2.7
(Seismic Resistant Design), and the ASCE (Section TC-8 on non-structural component seismic
response) and the Boiler and Pressure Vessel Code Committees of the American Society of
Mechanical Engineers (SG Heat Transfer Equipment - SC VIII).
• Johnson Controls currently works with the OSHPD leadership team on many of the above
committees and have provided input to their process for certifying non-structural components.
• In alignment with our commitment to serving the needs of our California health care facility
equipment customers, Johnson Controls is currently engaged with California structural engineers
to obtain the necessary pre-approvals from OSHPD for several key HVAC equipment families.
Johnson Controls is continuing its efforts to have our full complement of HVAC and Fire Life
Safety systems and non-structural equipment available with OSHPD approval. For specific
applications of seismic rated products, please contact the applications support team for each product.
CREDIBILITY: Wherever the requirements of the IBC have been enforced, Johnson Controls has provided seismic
certificates of compliance for HVAC products including: Large Tonnage Chillers, Air Handling Units,
Small Tonnage Chillers and Commercial Systems. These certificates are based upon a combination
of analysis and shake table testing and have been submitted to authorities having jurisdiction in
both the domestic and international markets.
OSHPD’s history of seismic regulations coupled with the higher risk of earthquake occurrence in
California, led to the formulation of a Code Application Notice (CAN) 2-1708A.5. This document
establishes the additional special inspections and qualifications that are needed for non-structural
components to be installed in California health care facilities. The document requires pre-approval
of a product or submission of approval on a job-by-job basis.
Johnson Controls is dedicated to serving the equipment certification needs of our California health
care facility customers. The cross-functional seismic team we established in 2004 proactively
works to maintain a deep understanding of the special requirements facing these customers.
Our commitment includes hosting an internal workshop focused on the impact of seismic
certification and OSHPD approval of HVAC equipment for health care facilities. The workshop
featured a respected California structural engineering firm that specializes in the field of seismic
certification of non-structural equipment for California health care facilities specific to the OSHPD
Code Application Notice (CAN) 2-1708A.5. The California structural engineering firm advised the
Johnson Controls product engineering team on testing protocol, process and compliance issues
inherent in seismic certification of non-structural product for health care facilities.
Our leadership in the seismic arena is part of our continuing commitment to deliver a more
comfortable, safe and sustainable world to our customers.
