Standard 90.1 uses a whole-building energy modeling approach. It relies on baseline building comparisons that make sense for offices or retail spaces but fail when applied to data centers. For instance, standard commercial buildings have high loads driven by weather and human occupancy. Data centers are driven almost entirely by internal IT equipment loads. The Innovation of Standard 90.4

Released in 2016 and updated significantly since (latest version 2022), ASHRAE 90.4 was the first standard written specifically for data center energy efficiency. It is now referenced in the IECC (International Energy Conservation Code) and many local building codes. ashrae 90.4 pdf

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 . Data centers are driven almost entirely by internal

To apply these regulations, perform calculations, or submit designs for compliance, you must reference the official documentation. The standard is updated on a regular cycle (e.g., the 2016, 2019, and 2022 editions) to reflect ongoing industry innovations.

90.1 regulates spaces designed for people. 90.4 regulates spaces designed strictly for IT infrastructure.
