The ANSI/TIA-942 is a quality standard for data centers. The standard specifies requirements for data centers including single tenant enterprise data centers and multi-tenant Internet hosting data centers. The topology presented in the standard is applicable to any size data center and covers all physical infrastructure including, but not limited to, site location, architectural, electrical, mechanical, fire safety, telecommunication, security and other requirements.

Data centers can be reviewed and certified for conformity to the requirements of the ANSI/TIA-942 standard.


Data Center Design and Implementation Best Practices

Data center construction and expansion is predicted to continue steadily worldwide.

With the increasing focus on reliability and efficiency, the initial design is more important than ever. Thus, professionals within data center design are required to have knowledge of mechanical, electrical and telecommunications systems and how they support the network and network equipment in the data center’s core.

ANSI/BICSI 002-2014, BICSI’s international best-seller, covers all major systems found within a data center. Written by industry professionals from all major disciplines, this standard not only lists what a data center requires, but provides ample recommendations on the best methods of implementing a design to fulfill your needs.


As the foundation standard for data center design, BICSI 002 features 17 chapters and 8 appendices, spread over 500 pages, covering the following and more:

  • Design methodology
    • Facilities, cabling, network, services and applications
    • Data center service outsourcing
  • Site selection and space planning
    • Modular and “container” data centers
    • Site services and hazards
  • Building structural and architectural requirements
  • Electrical systems
    • Utility to ITE power systems
    • Standby and backup power systems
    • DC power
    • Mechanical systems
    • Security and fire
      • Architectural, electronic and operational security
      • Fire safety for chimneys and aisle enclosures
    • DCIM and building systems
    • Telecommunications infrastructure
      • Hot and cold aisles
      • Cabinet airflow and cabling capacity
    • Network infrastructure
    • Data center commissioning & maintenance
    • Energy efficiency
    • Multi-site data center architecture
