Environmental Conditions

Most data centers are overcooled and have humidity control issues, which is a valid concern as room temperature and humidity are two of the main HVAC energy drivers. Air management issues should be addressed first, followed by environmental conditions. 

HIGH-LEVEL BEST PRACTICES 

Although most computer room air conditioners (CRACs) are controlled based on the return air temperature, air intake to IT equipment is the important specification to meet. 

  • At Minimum, Follow ASHRAE Guidelines for Data Center Temperature Ranges
  • Even Better, Operate at the Maximum ASHRAE Recommended Temperature Range (80.6°F)
  • Anticipate that Servers will Occasionally Operate in a Higher, but Allowable, Range (89.6°F)
  • Minimize or Eliminate Humidity Control Altogether
