Cooling is one of the top priorities for data centers and this makes effective energy management critical to their success. After all, data centers in the USA alone use over 90 billion kilowatt-hours of electricity per year – the total production of 34 giant 500-megawatt coal-powered plants. As commercial HVAC contractors, we know how important airflow management is to data centers – and how HVAC system best practices can help make this process more effective and more cost-efficient.

  • Constant monitoring: Monitoring and measuring PUE or power usage effectiveness (dividing the energy consumption of the data center by the energy consumption of the IT equipment it houses) is essential to understanding data center energy performance and recognizing opportunities for improvement. A PUE of 1.0 is considered very efficient, while a PUE of 2.0 and above is considered very inefficient.
  • Hot/cold aisle layout: This is a containment-style layout where hot and cold aisles are created by closing off cabinets, ducting the hot return air out of the cabinets. Ideally, air gaps should be sealed both within the IT racks as well as between them. Blanking panels are ideal for closing off empty rack slots and hanging plastic curtains to seal off the cold aisle is recommended.
  • Running your HVAC at the right temperature: Low temperatures are often touted as ideal, but many data centers are set to a far lower temperature than they should be, leading to rising cooling costs. The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) recommends a maximum of 80.6 degrees Fahrenheit – which is what Google uses. This can lead to a 2% savings in energy costs.
  • Server load: Servers that exclude all non-essential features are able to operate in a higher-temperature environment, lowering your overall cooling load.
