ENERGY STAR is one of the most recognised efficiency labels in the US market, but the exact requirements differ sharply by product category. This checker shows the governing specification, the headline efficiency threshold, the required test method, and a realistic cost range for whichever category you are targeting.
How it works
ENERGY STAR sets a separate specification for each product type, and the bar is defined in different ways:
- Products such as computers, monitors, appliances, and lighting must meet a numeric efficiency limit — an annual energy cap, an on-mode power ceiling, a minimum efficacy, or a margin above the federal minimum — verified by a defined test method in an accredited lab.
- HVAC equipment relies on AHRI-certified ratings such as SEER2 and AFUE.
- Commercial buildings are not tested in a lab; they are benchmarked in ENERGY STAR Portfolio Manager and must earn a 1–100 score of 75 or higher, verified by a licensed professional.
The tool maps your chosen category to its specification, threshold, certifying body, and typical cost.
Example and notes
A laptop manufacturer targeting the Computers Version 8 spec must keep annual total energy consumption under the category cap and meet idle and sleep power limits, then have a model family tested by an EPA-recognised body for roughly five to twenty thousand dollars. A building owner instead benchmarks twelve months of metered energy in Portfolio Manager and needs a score of 75-plus. Always confirm the current spec version and exact numbers on energystar.gov.
