Identify and prioritize the equipment with the highest rated power, because those are the items that will help you most. Your credit calculations will be based on the rated power of the equipment, not the number of individual Energy Star labeled machines. For example, the rated power of a copier is much higher than a laptop. If you buy only one of each, an Energy Star labeled copier will contribute more to the overall Energy Star labeled power percentage. 

If an Energy Star product is purchased as a replacement for older, less efficient equipment, you can assign it the higher rated power of the original product for the purposes of your calculation. Doing that gives these replacement products more weight in the calculations. The replacement must be purchased between project registration and when the project is submitted for certification. 

Sum the two columns and calculate the percentage of rated power that comes from Energy Star labeled equipment. It has to be at least 50% of total project equipment rated power to achieve the prerequisite, and 70%, 77%, 84%, and 90% for 1-4 points.  

The rated power can also be derived from listed ratings in volts and amps, which you multiply to obtain watts. Use the equation Watts = Amps x Volts. 

Add the rated power of all equipment and the rated power of Energy Star labeled equipment for your project to your equipment list. The rated power is usually imprinted on the equipment (in watts or kilowatts, i.e., kW) or you can use the standard values in the LEED Reference Guide, EAc1.4 Table 2 for equipment and appliances listed there.

HVAC, lighting, and building envelope products are excluded from calculations for this credit.

Your list has to include only equipment that is installed new or purchased within the LEED-CI project scope; existing equipment may be excluded (note that this is a change from the original 2009 release of the rating system—see the Bird's Eye View for more detail).

First identify which appliances and equipment are eligible for an Energy Star rating in your project. Check the Energy Star website for up-to-date listings of products and appliances that are available as Energy Star-labeled and create a project-specific list of these items. At minimum, the equipment list will include office equipment such as computers, fax machines, printers, scanners, multi-function devices, and monitors, as well as appliances such as refrigerators, dishwashers, washers and dryers, etc.

If required by the remediation plan, monitor the levels of identified chemicals onsite after the remediation is complete to ensure that contamination remains below the maximum thresholds. 

Verify any ongoing requirements with your regulating agency, as some state and local agencies require a contaminated and remediated site to be retested or monitored on an ongoing basis.
