The Cheapest Cooling Window Keeps Shrinking
A global analysis found rising heat and humidity are reducing the hours when data centers can rely on outside air alone.
Summary
A global analysis found rising heat and humidity are reducing the hours when data centers can rely on outside air alone.
University of Hawaiʻi at Mānoa researchers combined hourly weather observations, climate simulations, and a database of data-center locations to examine direct-air free cooling. They found that hot, humid periods exceeding recommended operating limits have become more frequent and longer, particularly in the tropics and southeastern United States. Projections extend the constraint through mid-century, while the harshest days can worsen faster than average conditions. The study does not calculate the energy bill of any named facility; it identifies a planning risk for a cooling method that depends on ambient weather.
