Critical power: Backup, standby and emergency power for hospitals
1 AIA CES APPROVED LU AVAILABLE FOR ATTENDEES UPON SUCCESSFUL COMPLETION OF AN EXAM
When designing backup, standby and emergency power systems for hospitals, there are several considerations beyond NFPA 70: National Electrical Code and other building code requirements that must be addressed. Electrical engineers must understand the specific owner project requirements for the building’s power systems and ensure that the generator specification and system topologies meet all those requirements for cost, construction schedule, component performance and system maintainability.
Engineers also need to be mindful of the construction process, and ensure equipment replacement is coordinated, temporary power strategies are identified and phasing concepts are developed.
- Know the codes and standards that define the design of emergency, standby and backup power systems.
- Identify important qualities and characteristics of generators for hospitals beyond the standard National Electrical Code and building standards.
- Learn best practices for specifying power systems and identify commonly seen specification errors or omissions.
- Review and compare various design topologies and solutions often seen implemented for hospitals. Discuss why certain solutions may be more or less favorable.
