This toolkit provides guidance and a logical sequence for users to employ the CoE Tools in order to achieve energy efficiency in their data centers. 

The DC Pro tools, DC Pro and the PUE Estimator are two "early stage" profiling tools designed for data center owners and operators to diagnose how energy is being used by their data centers and determine ways to save energy and money.

This document is a step-by-step guide to the DOE/LBNL Data Center Energy Assessment Process.

Excel-based worksheet to document metrics, actions, and measurements from data center assessments. It is recommended that users first use the DC Pro tool before using this worksheet.

Guide that covers how a portable and temporary wireless mesh assessment kit can be used to speed up the energy assessment process, reduce the costs, and overcome the issues with respect to shutdowns.

Two Excel-based tools designed to optimize air management in data centers while enhancing energy efficiency. Both tools were intended to help users accelerate the energy savings in data centers without affecting the thermal IT equipment environment.

Excel-based tool designed to help data center owners assess potential savings from efficiency actions in the electrical power chain of a data center.

Microsoft Word template for qualified assessors to report data center energy efficiency assessment findings. The document can easily be filled in with site data. An example assessment report using the template is also available here.

Comprehensive list of both high-level and detailed best practices. It is recommended to utilize this list of best practices within an energy assessment report.

IT equipment is at the core of energy consumption in data centers. Energy savings at the IT level will have an impact on essentially all energy use in these facilities.
