This Excel-based tool helps data center owners identify energy efficiency opportunities in the electrical power chain of a data center (transformers, generators, UPSs, power distribution units), plus lighting. The tool quantifies the energy and cost savings of the selected measures and calculates the payback periods for each measure. This new version, released in March 2020, offers a cleaner interface, a wider array of UPS load factors and control options (includes "ecomode"), and updated efficiency curves.
Note that this tool offers more energy efficiency options than Data Center Profiler (DC Pro) but is not a detailed 'investment-grade' audit tool. The savings estimates are driven by user inputs but based on typical practice and do not account for interactive effects. Actual savings will vary based on site-specific conditions and operations.
To use the tool, users will need to input:
- Basic configuration and efficiency information on electrical system components such as transformers, generators, uninterruptible power supply (UPS), power distribution unit (PDU) devices and lighting
- Energy use of electrical systems
