The Green Grid provides a data center Power Usage Effectiveness (PUE) Estimator which allows you to enter data on the estimated power usage of the components for a data center facility in order to properly estimate the PUE of the facility. This tool includes the concept of physical boundaries within a data center and also reports partial PUE for these boundaries. Results of the PUE estimation can be saved as PDF or CSV files, in a URL for later reference, or emailed. All data is saved anonymously.
Info-Tech designed the Data Center Energy Efficiency Calculator to help analyze metrics in order to
optimize power utilization and cooling in the data center.
