Designing emergency back-up power systems to withstand catastrophic events such as earthquakes and hurricanes is the topic of a new white paper available for download from MTU Onsite Energy. “How IBC-2009 seismic and wind-loading standards apply to emergency standby power systems” provides an overview of the most recent IBC standards, which have now been adopted by all 50 states as their de facto building code.

The paper explains the IBC’s occupancy categories and site class definitions, as well as the Importance Factor which designates whether an emergency standby power system is a critical or non-critical application. The document includes IBC seismic and wind-loading tables and maps to help power systems designers evaluate the need for seismically certified generator sets in specific applications. The document also covers the shared responsibilities of the entire design team including the genset manufacturer, installing contractor and building owner.

The free white paper is available from local MTU Onsite Energy distributors or can be downloaded from MTU Onsite Energy’s “Technical Info” section at .
