The Kitakyushu Data Center's Unrelenting Effort to Reduce Air Cooling Power Consumption

This session introduces the technical challenges tackled by facility engineers—who support our large-scale data centers from the physical layer—to reduce air conditioning power consumption.
In the data centers that support LY Corporation's services, optimizing the ever-increasing power consumption has become a crucial theme alongside ensuring stable server operation. In this session, we will introduce our initiatives to reduce air conditioning power in our data centers, sharing over a decade of accumulated know-how in free cooling (utilizing outside air) and practical examples of AI-driven automated air conditioning control. We will discuss from a facility engineer's perspective how we analyze physical environments—such as IT loads, server heat generation, air conditioning, and outside air—and how we translate this into PUE reduction. The content is designed to be easily understood, providing clear insights into facility optimization even for those without specialized knowledge of data centers or power equipment.
