Data centers and their HVAC systems are among the most energy-intensive infrastructures in the modern world. Operating 24/7, they power the computing functions that drive global economic, scientific, and technological advancements. The energy consumption of data centers is estimated to account for 3% of the total worldwide electricity use, growing annually by 4.4%. This immense energy demand has far-reaching economic, environmental, and performance implications—making cooling system efficiency a top priority for data center designers, often even more critical than availability and security. ASHRAE data center standards were introduced to address these challenges and guide engineers toward designing energy-efficient, reliable HVAC systems for high-performance computing environments.

ASHRAE Data Center Standards and Energy Consumption

ASHRAE studies reveal that the cooling infrastructure accounts for about 50% of a typical data center’s total energy consumption, followed by servers and storage devices (26%).
To meet the growing demand for high-capacity data centers while controlling operational costs, energy efficiency in HVAC design has become the core focus for engineers. This shift led to the development of new, more relevant standards for measuring and improving cooling system performance.

Data Center HVAC: Which Standards to Follow?

Previously, the industry lacked uniform standards for evaluating HVAC energy efficiency in data centers. The introduction of Power Usage Effectiveness (PUE) in 2010 provided a performance metric to measure efficiency but not a design framework. PUE helped benchmark performance but did not standardize system design, leaving gaps in achieving consistent efficiency.

The New Energy Efficiency Standard – ASHRAE 90.4

Recognizing this gap, the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) developed the ASHRAE 90.4 standard—specifically for data center design and operation.
Published in September 2016, this standard established minimum energy efficiency requirements for:

  • Design and construction
  • Operation and maintenance
  • Integration of renewable energy resources (on-site or off-site)

Unlike previous metrics, ASHRAE 90.4 directly addresses the unique energy and reliability needs of data centers, offering detailed guidelines for:
  • HVAC system efficiency
  • Electrical and mechanical system losses
  • Climate zone–based performance requirements
This standard represents a significant step toward creating sustainable, high-performance data center environments that balance energy efficiency, reliability, and scalability.

Why is HVAC efficiency so critical in data centers?
Because cooling systems consume nearly half of a data center’s total energy, optimizing HVAC performance directly reduces operational costs and environmental impact.
It’s a guideline developed by ASHRAE that sets minimum energy efficiency requirements for the design, construction, and operation of data centers.
Our HVAC systems are designed following ASHRAE 90.4, SMACNA, and ISHRAE standards to ensure optimal cooling performance and energy efficiency.
PUE measures how efficiently a data center uses energy; it’s the ratio of total facility energy to IT equipment energy. A lower PUE indicates higher efficiency.
Yes. We design modular, scalable cooling solutions suited for both enterprise-level and hyperscale data centers, ensuring maximum uptime and efficiency.
