| | You don't get approval for a roughly $250K project without some serious reasons and numbers. To start with an air flow dynamics analysis, and attempted improvements, utterly failed to improve our data center's environment. With the help of [[http://www.feace.com|FEACE]] we next embarked measuring our power consumption and cooling needs. The proposed solution is described above. The significant improvements are; abandon subfloor cold air delivery, reduce square footage cooled, free cooling below 45 degree ambient air, and much more energy efficient cooling units. |
