Assessing data center operating headroom for extreme weather

Weather extremes have always shaped data center design and equipment choices. Cooling systems, generators and electrical infrastructure are typically specified according to the assumed design day conditions, including the upper and lower temperature boundaries the infrastructure needs to withstand. Design day conditions are informed by at least 20 years of historical climate data. As the climate changes, however, extreme temperatures may become more frequent, increasing the likelihood of new records exceeding design conditions.

In many regions around the world, heat waves are becoming longer and winter storms more disruptive. At the same time, electrical utilities are operating under increasing strain as AI drives unprecedented demand for power, exacerbating weather-related issues. These trends are forcing operators to revisit their infrastructure resiliency.
