PORTFOLIO ENERGY PERFORMANCE
Better Buildings Challenge partners sharing data centers strive to decrease portfolio-wide power usage effectiveness (PUE) and to increase the percent improvement compared to a set baseline. Sabey's portfolio consists of nine data centers with 31 MW of critical load capacity. Sabey has improved energy performance by 42% from a 2014 baseline, surpassing their original goal of 20% by 2024. Energy savings have been achieved by implementing hot aisle containment, utilizing indirect evaporative cooling air handlers, installing variable speed drives on fans, and choosing an efficient UPS system. Sabey also continues to experience a growth in leased occupancy, and the higher utilization of their more efficient data centers allowed those facilities to operate in a more efficient part of their design curve.
