Electrical designs now heavily favor modular, high-efficiency UPS systems that maintain optimal efficiency even when operating at partial loads. Conclusion
The benefits of ASHRAE 90.4 include:
Data centers are the backbone of the modern digital economy. As artificial intelligence (AI), cloud computing, and big data demands surge, the energy consumption of these facilities has come under intense scrutiny. To regulate and optimize this massive power usage, the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) developed . ashrae 90.4 pdf
Just like the MLC, the calculated design ELC must be lower than the values specified in the standard. 3. Compliance Pathways
What is the specific or geographic location of the facility?
As resource-heavy artificial intelligence (AI), machine learning, and cloud computing workloads accelerate global infrastructure growth, optimizing power and cooling systems has become critical. Standard 90.4 provides the precise framework needed to balance high-density operational performance with environmental compliance.

Using the formulas in Section 6.3, calculate: = Chiller + CRAH fans + Condenser pumps + Cooling tower + Drycooler. Divide this by your Critical IT Load (kW) from the nameplates of your servers.
The ELC measures the efficiency of the power distribution chain. It quantifies the energy lost as heat as electricity travels from the utility entrance down to the IT racks.

ASHRAE 90.4 is increasingly being adopted into law. It is referenced by the and has been adopted by states like Oregon, Virginia, and Washington.
ASHRAE 90.4 is a standard that provides guidelines for the design, construction, and operation of data centers to minimize energy consumption and optimize efficiency. The standard, titled "Energy Standard for Data Centers," was first published in 2016 and has since become a widely adopted benchmark for data center energy efficiency.
The International Code Council (ICC) sometimes offers standards like ASHRAE 90.4 for free online viewing (non-downloadable) as part of their "Get Free Access" initiative. You cannot save the PDF, but you can search and read it.
