The size of a green data center is as small as possible, to maximize cooling efficiency. Construction is near-airtight; gaps that can leak large amounts of cool air are plugged.

Power converters are newer, adjustable units such as those made by Emerson, APC and Eaton, which are much more efficient than older, conventional models. These components take outside AC power and convert it to DC power with a minimum loss of power through excess heat.

An energy-efficient data center will have backup power generators (uninterrupted power supplies) that are tested at least monthly, will start immediately in an emergency, and will be able to carry the load for one to three days in the event of a prolonged outage. These generators should be powered by natural gas.
