Designers select equipment that meets or exceeds the exact performance values listed in the standard's tables.
If you open the PDF, you will notice that 90.4 doesn't just give you a simple number. It forces you to use to calculate your IT load diversity.

Unlike general commercial real estate, data centers are mission-critical facilities where a single minute of downtime can cost hundreds of thousands of dollars. For years, engineers used ASHRAE Standard 90.1 to evaluate data centers. However, its prescriptive requirements—such as mandating air-side economizers—regularly conflicted with data center reliability goals. ASHRAE 90.4 Energy Standard for Data Centers
It covers new data centers, additions to existing facilities, and major alterations that require new mechanical or electrical systems. Designers select equipment that meets or exceeds the
In the digital age, data centers are the backbone of global commerce, communication, and cloud computing. However, they are also notorious for their immense energy consumption. According to the International Energy Agency (IEA), data centers account for roughly 1% of global electricity demand. To combat this, engineers and facility managers rely on rigorous standards.
Data centers serve as the modern backbone of global commerce, cloud computing, and artificial intelligence. However, their immense computational power demands vast amounts of energy. For years, engineers struggled to apply generalized building energy codes to these highly specialized, mission-critical environments. PASSED
High-density Artificial Intelligence (AI) clusters generate more heat than traditional air cooling can handle. Future iterations of 90.4 are continuously refining metrics to accommodate direct-to-chip liquid cooling and immersion cooling architectures.
ANSI/ASHRAE Standard 90.4 is the dedicated energy standard for data centers, establishing minimum efficiency requirements for their design and operation. Unlike Standard 90.1, which covers general commercial buildings, 90.4 is tailored to the unique, high-intensity load requirements of data center environments. Core Compliance Metrics
