cents Achieve LEED certification for the physical building â $
cents Rely on more
efficient water cooling that potentially takes advantage of an on - site tower to chill water for cooling the system (thus reducing energy consumption by using nature's natural cooling power to chill water) â $

models to precisely design the interior of the building to maximize the efficiency of the HV / AC system for air - cooled computing systems â $
cents Tap into a mixed energy grid that relies on green energy sources such as solar, wind or hydroelectric (depending on geographic feasibility), along with a reliable city grid thus avoiding the need for the standard back - up Uninterruptible Power Supply (which will reduce equipment costs, minimize floor space used, and increase energy efficiency because systems that employ a UPS convert AC to DC and back, incurring substantial energy losses).
