A CEM is analyzing two candidate sites for a data center. Site A is in a cool northern climate; Site B is in a warm southern climate. Assuming similar electricity rates, which site offers a structural energy efficiency advantage and why?
-
A
Site B, because warmer air improves server processor efficiency
-
B
Site A, because the cooler climate enables more hours of economizer (free cooling) operation, reducing mechanical cooling energy
-
C
Site B, because higher ambient temperatures increase the delta-T across cooling towers
-
D
Site A, because northern utilities have fewer peak demand events
