A new paper in the Journal of Engineering for Sustainable Buildings and Cities entitled Data Center Waste Heat as an Emerging Urban Thermal Hazard: First Field Measurements of Neighborhood-Scale Air Temperature Impacts by David J. Sailor, Soroush Samareh Abolhassani, Eli P. Martin:
Data centers are among the fastest-growing sources of concentrated anthropogenic heat in urban environments. Despite 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. This short communication addresses that gap by presenting the first vehicle-based traverse measurements of air temperature in residential neighborhoods downwind of operational data centers.
This communication presents the first field evidence that operational data centers produce measurable warming in adjacent residential neighborhoods, with the downwind warming effect as large as 2.2 °C and average downwind air temperatures 0.7–0.9 °C warmer than upwind temperatures, extending more than 250 m downwind. These impacts arise from heat flux densities of 2000–6000 W/m2, magnitudes 2–6 times peak solar irradiance, equivalent to the heat emitted by thousands of residential buildings concentrated on a single site.
