According to code, where is emergency power not typically required?

Emergency power systems are critical for maintaining essential operations during a power outage, particularly in facilities that provide vital services or contain sensitive equipment. Data centers usually require robust emergency power solutions to ensure continuous operation, data integrity, and security.

In contrast, the other environments listed, such as hospitals, shopping malls, and residential buildings, typically have established safety codes that necessitate some level of emergency power to ensure safety and functional continuity. Hospitals, for instance, rely heavily on emergency power to support life-saving equipment and systems. Shopping malls may need emergency power for lighting and security. Residential buildings might not require extensive emergency power but often have basic backup systems for safety.

While data centers have high power demands and can operate with advanced backup solutions, the context suggests they are generally designed to manage these needs internally, often through dedicated uninterruptible power supplies (UPS) and generator systems. In certain codes or standards, especially those dictating minimum requirements for emergency power, it is common for data centers to focus on self-sufficiency while less critical environments may have looser requirements or none at all.

Thus, the reasoning aligns with the position that emergency power is not typically required in data centers compared to the other options presented.
