EPA develops and revises ENERGY STAR performance-based specifications to ensure that the ENERGY STAR label remains an effective consumer tool, identifying energy-efficient products whose use results in reasonable financial return without sacrificing product performance or features.
There are several circumstances that can prompt the revision of a specification. These include:
- Significant increase in market penetration of ENERGY STAR certified models
- Change in the Federal minimum efficiency standards
- Technological advancements
- Product availability limitation
- Issues with consumers realizing expected energy savings
- Performance or quality issues
- Issues with test procedures.
As part of ongoing program management activities, EPA monitors the extent to which these factors apply to each product category and prioritize specifications for potential revision accordingly. In general, a market share of ENERGY STAR certified products in a particular category of 35% or higher, elevates that product category for revision consideration. However, even as the market share rises, a meaningful specification revision may not be immediately feasible based on other factors, including lack of a consensus test procedure, limited product differentiation, limited potential for additional energy savings, or significant incremental cost to the consumer.
EPA documents the process for revising an ENERGY STAR specification, including identifying circumstances when a specification will not be revised, despite high market share of certified products.
