: Applies to new data centers and their systems, additions, and significant modifications. It generally excludes telephone exchanges and essential facilities. Key Metrics for Compliance
MLC stands for Mechanical Load Component, which measures the efficiency of the cooling system. ELC stands for Electrical Loss Component, which measures the efficiency of the power distribution system. Compliance with the standard is based on meeting maximum allowable values for these two metrics.
"No, sir. It’s the Aether Tower. I’m modeling the data center floors. I need ASHRAE 90.4. The specific requirements for the Mechanical Load Factor calculation. My baseline is rejecting the simulation and I can't find a clean copy of the current standard." ashrae 90.4 pdf
"I don't 'do' PDFs, son. I have the physical binders. But... give me a moment. I recall digitizing the tables for a lecture a few years back."

One of the most valuable aspects of ASHRAE 90.4 is the , which allows for a trade-off between the mechanical and electrical systems. If a data center design features an exceptionally efficient cooling system that beats the required MLC, the designer can "credit" those savings toward an electrical system that slightly misses the ELC target (or vice versa), provided the combined total energy use remains below the standard's threshold.
