Does your containment strategy comply with TITLE 24?

Tuesday, April 11, 2017

With Silicon Valley right in the middle of California, numerous prominent technology companies call the Golden State home to their corporate headquarters – and to their large data centers. California is home to 800 data centers, more than any other state. This implicates a very serious California state requirement: Title 24.


Date center managers deploying containment strategies in California must comply with the state’s Title 24 regulations in the sections referred to as “computer rooms.” The legislation defines a computer room as:


“A room whose primary function is to house electronic equipment and that has a design equipment power density exceeding 20watts/ft² (215 watts/m²) of condi¬≠tioned floor space.”

Compliance for Title 24 is required in:

  • All new construction computer room loads over 5 tons of cooling (17.5 kW IT load)
  • Any new computer room in an existing building that adds more than a total of 20 tons of cooling (70 kW IT load) above 2013 baseline
  • Any addition to an existing room that adds more than a total of 50 tons of cooling (175 kW IT load) above 2013 baseline


Containment is required when rooms reach above a 175 kW total design IT load. The method of containment can be selected by the end user as long as hot/cold-air mixing is substantially prohibited.


Expansion of an existing computer room is exempt if IT racks have a design load under 1 kW and equivalent energy perfor­mance based on engineering analysis.


Regardless of the computer room layout, containment solutions must be flexible if data center managers want to meet Title 24. And with so many data centers in the Golden State, these regulations are worth knowing about!


To support these growing regulations and energy efficiencies that are being placed on data centers, Legrand has recently launched a new containment solution that is designed to be easy to specify and install using modular components. To learn more about the new containment solution, visit
