The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) recommends an increase in the environmental temperature in data centres or the supply temperature to cool the active hardware to a delta T between 18 and 27 degrees Celsius to save energy and increase the flexibility of cooling systems in data centres. Every additional degree Celsius above the initial temperature reduces cooling system load by approximately three to five percent and translates directly into potential energy savings.
