Summary
This study presents the first direct field measurements of air temperature impacts from data center waste heat on surrounding residential neighborhoods. Using vehicle-based traverse measurements at four data center facilities in the Phoenix, Arizona metropolitan area (ranging from 36 MW to 169 MW), researchers found downwind air temperature warming up to 2.2 °C, with average warming of 0.7–0.9 °C compared to upwind areas. Thermal signatures were detectable up to 500 meters from facility perimeters. The paper highlights that data centers reject waste heat equivalent to the electricity consumption of tens of thousands of households, concentrated in small footprints, and warns that with U.S. data center capacity projected to more than double by 2030, this represents an undocumented urban thermal hazard requiring attention from data center and urban planning communities.

· 5 pulledDespite heat flux densities that exceed peak solar irradiance by a factor of 2–6, their thermal impacts on adjacent communities have never been directly measured or reported in the peer-reviewed literature.
Five traverses at four facilities in the Phoenix, Arizona metropolitan area... reveal downwind air temperature warming as high as 2.2 °C, with average downwind air temperatures 0.7–0.9 °C warmer than corresponding upwind areas.
Thermal signatures were detectable at distances up to 500 m from facility perimeters.
The 36 MW Mesa facility rejects waste heat equivalent to the electricity consumption of approximately 40,000 households, while the 169 MW Chandler campus is equivalent to over 180,000 households, both concentrated into footprints smaller than a single residential subdivision.
With U.S. data center capacity projected to more than double by 2030, these findings establish data center anthropogenic waste heat as a previously undocumented urban thermal hazard demanding attention from the data center and urban planning communities.
